A Great Dream – By Kit Pharo

In response to last week’s PCC Update, a subscriber in Illinois sent me the following quote.   As you know, I like to share favorite quotes in our PCC Updates and Quarterly Newsletters.   This quote really packs a punch!

“A great dream is not as good as a great memory.   The dream can be had by anyone.   The memory – must be made.”    ~ Eric Thomas

This quote speaks for itself and does not require commentary.   Nevertheless, I feel compelled to comment.   In my lifetime, I have met many, many people who had GREAT dreams.   Unfortunately, very few of those people made their dreams come true.   Most never did get off the starting line.   They always came up with excuses to put off the most important things in their life.   As I think back, I find this to be very sad.

I want to challenge you to get off the starting line and do what it takes to make some of your dreams come true.   Turn those great dreams into great memories.   Do you have some personal dreams or family dreams?   I hear people all the time talking about the things they have on their Bucket List.   Most of those people, however, never get beyond talking about their dreams.   Before you know it, they no longer have the ability or the desire to do the things on their Bucket List.   Consequently, they did not create any great memories.

Do you have some business dreams?   Would you like to make your business substantially more profitable, enjoyable and sustainable?   Would you like to create a business the next generation is excited to become a part of?   As Walt Disney once said, “If you can dream it, you can do it.”   Please remember, though, the present is different from the past and the future will be different from the present.   Creating a bigger and/or better business will involve CHANGE.   There is no getting around that fact.   While everyone else is afraid of change, we should be embracing it!

Resistance to Change –

By Kit Pharo

People hate change!   Nowhere is this more prevalent than in agriculture.   It seems to take years for people in agriculture to make simple changes – even though they know the change will be for their own good.   I must confess that I too am reluctant to change.   I may not hate change as much as most people, but it still makes me uncomfortable.

I read a neat little Seth Godin book entitled Tribes.   In this book, Seth spends a considerable amount of time discussing the status quo and its fear of change.   He believes change is inevitable.   I don’t think anyone can argue with that.   Change is a normal and necessary part of life – and the sooner we embrace it, the better off we will be.

Seth says, “Change almost never fails because it was too early.   It almost always fails because it was too late.   By the time you realize your corner of the world is ready for change, it’s almost certainly too late.   It’s definitely not too early.”   Mr. Godin goes on to say, “There may be a small price to pay for being too early, but there will be a huge penalty for being too late.”

We use the term Herd Quitter to refer to people who have enough courage to break away from the status quo, herd-mentality way of thinking.   It is more about thinking for yourself than anything else.   Following the crowd (herd) and doing what everyone else is doing is never the best way to manage a business.   Dare to be a Herd Quitter.   Dare to enter the New Frontier in beef production.   Dare to make the necessary changes in your operation while you still have a choice in the matter.   The sooner, the better!

Bull Selection – Using Economically Relevant Traits

Sire selection often encompass a variety of factors such as how well a bull fits into the breeding objectives of your operation, breed, conformation, pedigree, birthweight, and price. Recent surveys from western Canada in 2014 and 2017, Ontario in 2015/16, northern Ontario and Quebec in 2015/16, and Atlantic Canada in 2016/17 production years asked respondents to rank their top bull selection criteria.  There wasn’t a lot of variation between regions with breed, conformation, pedigree, birth weight, individual performance, expected progeny differences (EPDs), and temperament all being highly ranked by survey participants.   

Some of the criteria, like breed, may influence sire selection due to the desire to capture heterosis or breed complementarity effects.  Conformation is important for longevity and ensuring the bull gets the job done during the breeding season.  Having a bull with a desirable temperament makes everyone’s lives easier, especially if there are children or older individuals involved in the operation.  Individual performance and birth weight may give some indication of how the bull’s progeny may perform, but a better indicator in this area is actually the bull’s EPDs. Response to selection using EPDs is 7-9 times more effective than selecting based on individual animal performance7.

The question is, how well do these various selection criteria translate into profit?

Answering this question means taking a look at your operation.

  • What are your breeding/marketing goals?
  • Which traits affect the profitability of your operation?
  • What constraints does your operation have (forage resources, labour, etc.)?
  • Do you raise your own replacements or purchase them4?

Once those questions are answered, there are likely a number of traits you have identified as important to your operation.

While a number of data sources exist to help you evaluate the contribution of a potential herd sire to improving the traits of interest, it is important to recognize whether the traits you have identified are indicator or economically relevant traits.  Good record keeping is crucial to determine whether or not progress is being made in the traits you have identified as important to your operation’s productivity and profitability.

Economically relevant traits (ERTs) are those that are directly associated with a source of revenue, or a cost.  Not all EPDs represent ERTs – instead they use a related (or indicator) trait to estimate the ERT.

One of the best examples is birth weight.  Decreasing a bull’s birth weight by 5 lbs does not have any associated income or costs, but is often used as a bull buying criteria in an effort to reduce calving problems.

The actual ERT in this case is calving ease, as an increase in calving problems will reduce calf survival (less calves to sell), incurs higher labour costs (pulling calves, or more time spent monitoring), and delays cow rebreeding (younger and lighter calves to sell next year).

Similarly, ultrasound for carcass traits is another suite of common indicator traits, while the ERTs are the actual carcass measurements (weight, yield, and marbling).

We all recognize fertility (in both sires and dams) as a trait that has the biggest impacts on profitability.  But fertility has relatively low heritability, meaning that cumulative environmental influences (e.g. nutrition, weather, etc.) generally have a larger impact than genetics.  In Canada, some genetic evaluations do not report any EPDs at all for ERTs related to female fertility. While most evaluations include scrotal circumference (indicator), it actually has a near zero relationship with heifer pregnancy rate (ERT)

In the Canadian context, a stayablity or length of productive life type of EPD (probability of an animal remaining in the herd for X period of time or awarding more credit to cows remaining longer in the herd), while an ERT itself, is also the best proxy for fertility given the lack of EPDs in this area, as the most common reason for a cow to be culled is because she’s open.

When EPDs for both indicator and ERTs for the same trait are included in genetic evaluations (e.g. calving ease and birth weight), make sure you focus on the EPD for the ERT and not the indicator trait. The indicator trait cannot add more information to the selection process, as it is already used in the calculation of the EPD for the ERT in the first place.  When an EPD for an indicator trait is available, but no EPD exists for the ERT (e.g. scrotal circumference and heifer pregnancy rate), it can result in an over or under-estimation of the ability of the indicator trait to predict the ERT3.

Given the plethora of EPDs available, trying to sort through ten or fifteen or twenty individual EPDs that may not have relevance to your particular operation can easily lead to information overload.  By focusing on the ERTs, you can eliminate those bits of information that will not directly impact your operation’s profitability.

For example, if you’re using a terminal system (not keeping replacements) and selling at weaning, the weaning weight EPD is going to be one of your most important ERTs.  If you tend to retain ownership through to slaughter, the more relevant ERTs are carcass weight, quality, and yield grades.

In some cases, whether a published EPD is an indicator or ERT will depend on how that EPD is reported.  For example, carcass trait EPDs calculated using combination of ultrasound and actual carcass data would be ERTs (e.g. marbling score), but those reported on an ultrasound data basis (e.g. percent intramuscular fat) would be indicators.  Table 1 contains some common traits that may or may not have a published EPD in your breed of choice and whether they are an indicator or ERT.

Table 1.  List of selected EPDs characterized as indicator or ERT

Adapted from (4) and (6) (see references below).  This is not an exhaustive list.

Many genetic evaluations offer selection indices in addition to individual EPDs.  These are calculated by placing an economic weighting on individual EPDs to create a multi-trait selection model for different types of broad production systems (generally maternal or terminal).  These provide a way to objectively categorize a set of animals using the same criteria throughout.  Examples include the Canadian Simmental Association’s All Purpose Index (API) and Terminal Index (TI), AgSight’s BIO$ Economic Index, or the Canadian Hereford Association’s Maternal Productivity Index (MPI) and Feedlot Merit Index (FPI).  The indices offered by most breed associations are fairly robust across production environments, keeping in mind their overall objective – don’t expect high ranking terminal index bulls to give you stellar replacement heifers.


Ideally, selection indices would be tailored to each individual operation’s identified ERTs, with different economic weightings depending on the production system, but the creation of customized selection indices with real-world economic weightings requires detailed cost and return information and a complete understanding of the complex genetic relationships between traits.  This type of model may also present some difficulty for seedstock producers, as marketing based on a fluid index (where a bull could be in the top 1% for X trait in one type of production system, but only in the top 50% for the same trait in another production system) would be challenging.4

Regardless, the amount of detailed information required to populate these types of models may not be readily available for the average producer.

By identifying ERTs, you can narrow your selection focus to the EPDs that matter most for your breeding goals, increasing the likelihood that the decisions you make will actually have an impact on your bottom line.

Reducing Heifer Development Costs By Growing Smaller Cows and Using Lower-Quality Forages

By   /  October 30, 2017  /  4 Comments

More recent research is overturning old ideas about heifer development and providing ways to reduce costs while maintaining breed-back rates and longevity in the herd.

his article comes to us from Aaron L. Berger, Extension Educator, and Rick N. Funston, Beef Reproductive Physiology Specialist, both from University of Nebraska Extension.

In the past several decades, post-weaning development of replacement heifers has focused on feeding heifers to reach a target body weight of 60 to 65 percent of mature weight at breeding to achieve acceptable pregnancy rates (85 to 95 percent) in a breeding season that ranges from 45 to 70 days. This development system was based on historical research that indicated heifers bred at approximately 14 months of age should reach this target weight to achieve acceptable pregnancy rates.

In an effort to reduce costs, recent research has focused on comparing traditional, more intensive replacement heifer development systems to systems utilizing more inexpensive feed resources to develop heifers to lighter target body weights at breeding (i.e., 50 to 57 percent of mature weight compared with the traditional 60 to 65 percent of mature weight). Research has demonstrated replacement heifers developed to lower target weights — but on a positive plane of nutrition before the breeding season through calving — can have acceptable pregnancy rates and longevity.

These lower-input systems allow producers to develop replacement heifers at lower cost without sacrificing reproductive performance. This publication highlights why recommended target weights for replacement heifers have changed and key aspects of successful low-input replacement heifer development systems.

Why Recommendations for Heifer Target Body Weight at Breeding Have Changed

Genetic Selection
Much of the research recommending heifers be at a target weight of 60 to 65 percent of mature weight by breeding was conducted from the late 1960s through the 1980s. Since then, the genetic makeup of the U.S. cowherd has changed significantly. Age of puberty does not seem to be limiting heifer development programs as it did in the past. Heifers are reaching puberty at younger ages and at a lower percentage of their mature weight than has occurred historically.

Research contributing to this publication was conducted using current British and Continental genetics in the United States. The following genetic trends have been realized by widespread management changes and the use of Expected Progeny Differences (EPDs) in the selection for a variety of traits, including scrotal circumference and yearling weight:

Decreased age at calving.
Fundamental changes to the U.S. cattle industry include the now common management practice of heifers being bred as yearlings and calving for the first time as 2-year-olds, rather than calving as 3-year-olds. Over time, this practice has indirectly selected for heifers that reach puberty at an earlier age lower percentage of mature weight.

Increased scrotal circumference in bulls.
Average yearling scrotal circumference EPD for most breeds has increased significantly since the 1980s. Scrotal circumference in bulls moderately correlates with age at puberty in heifers. As average scrotal size increases, heifer age at puberty decreases. Selecting yearling bulls for larger scrotal size may have indirectly resulted in decreasing the average age heifers reach puberty.
Increased mature cow weight. Major U.S. cattle breeds have been selected for larger yearling weights, resulting in heavier mature cows. However, increase in mature cow size has not resulted in heifers delaying puberty to larger weights. Consequently, heifers are reaching puberty at a lower percentage of mature weight than in the past when mature cow weights were lower.

Greater Understanding of Heifer Development Physiology

Timing of body weight gain.
Timing when body weight gain occurs in replacement heifer development can reduce development costs. Heifers developed to 50 to 57 percent of mature weight at breeding can still achieve acceptable pregnancy rates (80 to 95 percent during a breeding season ranging from 45 to 70 days ) if the period of slower weight gain is followed by a positive energy balance prior to and through the breeding season.

Heifers developed on crop residue or native range at low rates of gain have demonstrated compensatory gain in the spring when placed on higher quality forage. When this compensatory/higher rate of gain coincides with breeding, either A.I. or natural service, it appears to benefit conception and maintenance of pregnancy.

These research results contrast results of heifers developed in a drylot on moderate to high rates of gain through the winter. When placed on forage prior to or during the breeding season, heifers previously on a moderate to high level of gain often experience minimal weight gain, or in some cases, weight loss, for several days while adapting to this new forage resource. This neutral or negative nutritional change occurring around breeding may negatively affect conception rates and/or maintenance of pregnancy.

An appropriate level of nutrition immediately prior to breeding and continuing through subsequent calving is required for low-input developed heifers to experience compensatory gain and attain sufficient size and body condition. This allows them to successfully calve and rebreed. Providing adequate nutrition during this phase has shown rebreeding rates as 2-year-olds to be equal to or greater than heifers that received higher energy during development and were a larger percentage of mature body weight at breeding. Body condition at calving should be 5 or greater.

Many producers using a low-input replacement heifer development system retain all potential replacement females and expose them for a short (45 days or less) breeding season. Remember, as the breeding season is shortened, fewer heifers will likely become pregnant. Retain more heifers than needed for replacements to determine how heifers will respond to a lower-input development system. Non-pregnant heifers grown in a low-input development system can be a profitable commodity as they can be marketed as feeders.

Protein supplementation.
Heifers developed on low-quality forage often require protein supplementation to more effectively use this feed resource and meet nutritional requirements. Avoid feeding excess protein when energy is limiting because it can negatively affect reproduction if this occurs immediately prior to or during the breeding season.

Use of ionophores.
Monensin (Rumensin®) and lasalocid (Bovatec®) are ionophores approved for growing heifers. Ionophores affect the microbial population, increasing the efficiency of forage digestion. Research has shown either of these compounds in replacement heifer diets can decrease age at puberty and increase conception rates. In addition, ionophores can increase daily gains by 0.1 to 0.2 lb/day depending on the quality of the diet.

Possible Negative Effect of Over-Conditioned Heifers on Future Fertility

Heifers developed in an intensive system of high energy feeds often can be fed to a body condition score of 7 or greater at first breeding. Heifers over-conditioned at their first breeding may perpetuate the need for a higher level of body fat (requiring more feed resources) to breed back as 2- and 3-year-olds. Yearling heifers with a body condition score 5 at their first breeding are more likely to be fertile and conceive at a similar body condition score as 2- and 3-year-olds. Overfeeding heifers prior to breeding increases heifer development costs and may have a detrimental effect on heifer longevity.

Learning to be a Cow

Replacement heifers developed on forages (often low-quality) that they will consume as cows often are better adapted to their environment than heifers in intensive development systems. Grazing is a learned behavior, which suggests that heifers developed on grazed forages may acquire more experience consuming forage, allowing them to better use these same feed resources as cows. Intensively developed heifers appear to undergo a learning and adaptation phase when introduced to forages. This can coincide with a time when they are already nutritionally challenged as growing yearling heifers being bred for their first calves.

Supplementation Strategies for Summer Breeding of Heifers

Current research validates the importance of nutrition prior to and through the breeding season to achieve acceptable pregnancy rates for heifers developed in a low-input system. Many cow-calf producers have moved to later spring calving to decrease labor, increase flexibility in marketing calves, and decrease harvested feed costs.

This shift to later spring calving has resulted in heifers being bred in mid to late summer on pasture and rangeland where forage quality is often decreasing. These heifers, while adequate in size and age for breeding, often have decreased pregnancy rates. A recent study demonstrated supplementing heifers during a late summer breeding season with a protein supplement (1 lb/hd/day of a 30 percent crude protein cube containing Rumensin®) on native range resulted in 20 to 25 percent greater pregnancy rates than heifers not receiving the supplement. When breeding occurs during decreasing forage quality, protein supplementation prior to and during the breeding season may be important to the success of the heifer development system.

Summary

Development systems targeting 12- to 14-month-old heifers to be at 50 to 57 percent of mature weight at the time of breeding can result in acceptable pregnancy rates. These systems must employ adequate nutrition prior to and through the breeding season. These heifers need to experience compensatory gain from breeding to calving to ensure adequate size and body condition to calve and rebreed successfully.

Development systems using lower-quality forages allow heifers to be developed at lower costs than intensive development systems. When changing to a lower-input system, initially retain more replacement heifers than needed. This will help determine how herd genetics will respond to a reduced nutritional environment during development.

Evaluate how many replacement heifers to keep

Each year, commercial cow-calf operations must decide how many replacement heifers are grown out to be put in the breeding pasture. Individual ranches must make the decisions about heifer retention based upon factors that directly affect their bottom line. Stocking rates may have changed over time due to increases in cow size. Droughts have caused herd sizes to fluctuate over time.

Matching the number of cattle to the grass and feed resources on the ranch is a constant challenge for any cow-calf producer. Also, producers strive to maintain cow numbers to match their marketing plans for the long-term changes in the cattle cycle. Therefore, it is a constant struggle to evaluate the number of replacement heifers that must be developed or purchased to bring into the herd each year.

As a starting place in the effort to answer this question, it is important to look at the “average” cow herd to understand how many cows are in each age category. Dr. Kris Ringwall, director of the Dickinson, ND, Research and Extension Center, reported on the average number of cows in their research herd by age group for a period of over 20 years.

Figure 1 depicts the “average” percent of cows in this herd by age group. The graph indicates that the typical herd will, “on the average,” introduce 17 percent new first-calf heifers each year. Stated another way, if 100 cows are expected to produce a calf each year, 17 of them will be having their first baby. Therefore, this gives us a starting point in choosing how many heifers we need to save each year.

Next, we must predict the percentage of heifers that enter a breeding season that will become pregnant. The prediction is made primarily upon the nutritional growing program that the heifers receive between weaning and breeding.

Researchers many years ago found that only half of heifers that reached 55 percent of their eventual mature weight were cycling by the time they entered their first breeding season. This data was reinforced with data from Oklahoma State University. If these heifers were exposed to a bull for a limited number of days (45-60), not all would have a chance to become pregnant during that breeding season. Therefore, it would be necessary to keep an additional 50 percent more heifers just to make certain that enough bred heifers were available to go into the herd.

Remember the increased number of heifers will require additional pasture, increased health costs, and increased breeding costs. If natural breeding is used, extra bull power will be necessary. If artificial insemination (AI) is the method of choice, the larger number of heifers will require increased synchronization and AI costs. As soon as possible the heifers should be pregnancy checked and the open heifers marketed as stocker heifers.

However, if the heifers were grown at a more rapid rate and weighed 65 percent of their eventual mature weight, then 90 percent of them would be cycling at the start of the breeding season and a much higher pregnancy rate would be the result.

Even in the very best scenarios, some heifers will be difficult or impossible to breed. Most experienced cow herd managers will always expose at least 10 percent more heifers than they need even when all heifers are grown properly and weigh at least 65 percent of the expected mature weight.

The need to properly estimate the expected mature weight is important in understanding heifer growing programs. Cattle type and mature size have increased over the last half century. Rules of thumb that apply to 1,000-lb. mature cows very likely do not apply to your herd.

Watch sale weights of culled mature cows from your herd to better estimate the needed size and weights for heifers in your program. Most commercial herds have cows that average about 1,200 lbs. or more. This requires that the heifers from these cows must weigh at least 780 lbs. at the start of their first breeding season to expect a high percentage to be cycling when you turn in the bulls.

This discussion is meant to be a starting place in the decision to determine the number of heifers needed for replacements. Ranchers must keep in mind the overriding need to understand what forage base resources that they have available to them. — Glenn Selk, Oklahoma State University emeritus extension animal scientist

Setting heifers up to breed early has lifelong benefits

Experts from Zoetis and the University of Nebraska shared the latest technology available in the art of selecting replacement heifers during a strategic heifer retention seminar last week at the McCook Farm and Ranch Expo in McCook, Neb.

Kent Andersen of Zoetis, the world’s largest animal health company, told producers they should select heifers that breed up early for genetic, environmental and management reasons.

“I would also encourage all producers to work with their veterinarian to develop a good vaccination program,” he said. “You should be willing to do everything you can, management-wise, to take advantage of that genetic experience.”

With replacement heifer development costs averaging $1,000 for the heifer, $500 in costs from weaning to breeding and $500 in costs each year after that to retain a heifer, it is not cheap to develop replacement heifers. In fact, Andersen estimated each heifer to have a minimum value of $1,700-$1,800.

“With that much money at stake, you will want to set the stage for success,” he said. “It is important to minimize dropouts as much as possible. Do everything management-wise to set them up for success.”

The first step is to make a good pool of replacements, Andersen said.

“You can accomplish that by buying the right bulls that have good maternal traits,” he explained.

Ranchers also should consider selecting heifers that have a good visual appearance and are born earlier. They also might want to have a veterinarian score the heifer’s reproductive tract, measure the pelvis and perform a pregnancy test if there is a possibility the heifer was bred while still on the cow.

The dam’s production soundness should be considered, and production records like birth weight and weaning weight evaluated. Producers should eliminate any heifers from dam’s with bad bags or disposition problems.

“Use all the information you have available to select heifers that are most likely to succeed,” Andersen said.

“There are some traits you can’t see,” he continued. “But, you could utilize leverage technology to determine which heifers are the best, and which cows are more likely to be in the herd long-term.”

Using genetic testing methods, like the GeneMax system, Andersen said he can tell a lot about how a producer selects his bulls. In fact, by performing the 150K marker test, Andersen said he can tell more about a herd of cattle than from a producer who gathered data for long periods of time.

The GeneMax Advantage test can be used to test Angus-based females and Angus-based bull battery. This genetic test scores cattle from 1 to 100, with a score of 50 considered average.

“Using indexes like this are meant to simplify life,” he said. “It helps producers find the heifers that are the most efficient to help keep cow costs sensible.”

However, Andersen told producers they should still think about which heifers should be culled and which ones have the look of being highly productive in the herd.

“Some people think of these tests as a product to use to keep or cull, but don’t put it in a drawer and forget about it,” he cautioned. “I can tell a lot about a producer’s bull buying habits, based on how their heifers test. The genetic benefit of doing these tests is to show producers what they should be paying attention to when they are purchasing a bull.”

The test costs $28 a head, but Andersen admits it isn’t very effective to test cattle that are less than 75 percent Angus. While the company focuses on developing genetic tests that can make predictions on crossbred cattle, it still can be used to determine the percentage of each breed in an animal.

“This is the first step in unlocking the genetic merit in a hybrid animal,” he said.

Travis Mulliniks, beef nutritionist with the University of Nebraska West Central Research Center in North Platte, talked about the importance of nutrition in developing and breeding replacement heifers.

“Reproduction is the main factor limiting production efficiency in the beef cow herd,” he said. “Management early in life has long-term implications. Early conception increases longevity in the herd.”

The break-even cost for heifer development takes three to five years, according to Mulliniks. He said nutrition plays a large role in getting heifers bred.

“Nutrition at the time of breeding is critical,” he explained. “It is not based on how much you feed, but what you feed that is important.”

He warned producers they should only moderately select heifers for milk production.

“Angus cows produce more milk today than a high milking Holstein did in 1970. At some point, we need to quit putting so much emphasis on milk production,” he said.

Burke Teichert: 10 thoughts on heifer development

One of the biggest determinants of ranch profit is the cost of developing or acquiring herd replacements.

Much has been written recently on heifer development. Here are 10 comments, in no particular order, related to the subject:

1.     Know going into it, replacements will determine ranch profitability.

One of the biggest determinants of ranch profitis the cost of developing or acquiring herd replacements. Of the various accounting methods you might use, cow acquisition costs must be absorbed in the sale of cattle.

2.     Develop or buy?

Therefore, the first decision to make is whether to develop your own heifers or buy replacement cows—notice that I said cows. While purchased heifers might be slightly better genetically, they have the two toughest years of their life ahead of them and will have to adjust to a new environment after relocation. If you are not raising your own, buy bred cows. The terminal sires you use will be the major determinant of the quality of your calves.

3.     Keep that breeding season short, and then cull.

I have continually encouraged keeping all but the poorest heifer calves and exposing them to AI and/or bulls for a very short time—not more than 30 days. I’ll guarantee that the bulls and the environment will select better heifers than you will. The main reason is that heifers that breed and calve late cannot live long enough to catch up with those that breed and calve early regardless of genetic superiority in non-fertility traits.

4.     Develop those heifers on grass.

I don’t like to develop heifers in pens. I think they should be wintered like dry wintered stockers on grass, crop residues or hay along with appropriate protein and mineral supplementation.

Work at the Fort Keogh Livestock and Range Research Station at Miles City, Mont., and at New Mexico State indicate that including Rumensin and a high proportion of bypass protein in the yearling heifer supplement will pay reproduction dividends into the cows’ later life. No, they won’t all get pregnant with this kind of development, but the open heifers should be profitable, and the pregnant heifers are set up to become very good cows.  It’s been so long ago that I can’t remember the numbers, but on the ranch where I was raised in western Wyoming at 6200 feet elevation with a lot of snow, our heifer calves were fed hay and free choice salt. Occasionally, I remember feeding them a little grain.

5.     Nutrition matters.

Since heifers developed in this manner are smaller than typical heifers and still need to grow while getting ready to calve, it is good to ensure adequate protein and quality pasture as they approach calving season or perhaps before the second breeding season if you are calving in summer or fall. You would much rather that they fail to breed and fall out as yearlings than as two year olds.

6.     Is reproduction really a genetic trait?

There are those who will argue that the heritability of reproduction is low. You can almost make any yearling heifer get pregnant if you provide enough feed. Therefore, you could argue that most of reproduction is due to management.

However, if you restrict inputs or expect the animals to get pregnant in tougher conditions, I think the heritability becomes higher—at least there is certainly more segregation when all are given the same chance to get pregnant. But, even if the heritability is low, it still makes economic sense to select the heifers that become pregnant early in the breeding season because of their economic advantage over late bred heifers.

In this argument, a short calving season and low heifer development costs are significantly more important economically than genetics for growth and carcass. That’s not saying you abandon growth and carcass, but don’t let them rule.

7.     Let’s emphasize a short calving season one more time. It’s important.

The cows in most herds are fairly evenly distributed under a bell shaped curve—with a few very good cows, a few bad ones and the rest scattered in between with more around average. We should cull the obviously bad ones every year. That will keep the bottom end cleaned up fairly well.

It’s really hard to tell the truly good cows. We might know the weaning weight of their calves. We might know their calving interval. We might know they are problem free.  But, we don’t know how much feed they ate in relationship to the pounds of calf they produced. We probably don’t know their contribution to carcass quality, etc.

When all traits are considered economically, I think it is really difficult to know how to separate the good cows from the average except by calving date.  So, set your herd up to calve early by selecting heifers that calve early—hopefully as a result of first cycle conception.

8.     Are your bulls really that good?

One more question—If you are buying good bulls, why will you keep a cow when you are not willing to give her daughter a chance to breed? If you won’t keep the heifer calf, would that not be a reason to cull the mother? Or is it possible that the bulls you bought aren’t so good after all?  If sire and dam are both good, shouldn’t you give the daughter a chance to show she can get pregnant on time?  If she does that, she’s already on the road to being pretty good.

9.     Steers as a by-product?

I have a good friend who retains all of his steer calves to run as yearling stockers. Even doing that, he says that his steers are a by-product of his bred cow business. By keeping and exposing most of his heifers, he has a good number of bred cows to sell. He does breed the heifers longer than I recommend, but sells those that breed later—after 24-30 days depending on breeding success.

While I don’t believe in buying bred heifers for replacements, I don’t have any problem selling them to those who still haven’t figured it out. In the meantime, he doesn’t keep many cows over six years old—just the very best.  So, when you buy cows from him, you will be getting good young cows.

10.  Terminal cross for growth, carcass

For many people, it is much simpler to buy replacement cows from those who make good cows as described above. Then breed them to bulls that favor growth and carcass.

Show-Me-Select heifers add genetics when replacing old beef cows in herd

Proven replacement heifers build genetics in beef herds. They increase future calf value from the herd.

Buying Show-Me-Select replacement heifers gives a quicker boost to herd genetics than growing your own, says Dave Patterson, University of Missouri Extension beef specialist.

Increasing numbers of herd owners specialize in raising superior SMS replacements. Buying them adds heifers from the top proven sires in the breed.

Six fall sales of spring-calving SMS heifers start Oct. 28.

Sale dates, locations, times and contacts are:

-Oct. 28, Farmington Livestock Auction, 7 p.m.; Kendra Graham, 573-756-4539.

-Nov. 18, Joplin Regional Stockyards, Carthage, 7 p.m.; Eldon Cole, Mount Vernon, 417-466-3102.

-Nov. 18, Kirksville Livestock, 6 p.m.; Zac Erwin, 660-665-9866.

-Nov. 26, Kingsville Livestock Auction, 11 a.m.; David Hoffman, Harrisonville, 816-380-8460.

-Dec. 3, Fruitland Livestock Sales, 1 p.m.; Erin Larimore, Jackson, 573-243-3581.

-Dec. 10, F & T Livestock Market, Palmyra, 12:30 p.m.; Daniel Mallory, New London, 573-985-3911.

Producing superior heifers with calving-ease genetics isn’t a quick process. Heifer buyers gain benefits of years of work by developers. Purchased genetics show up in the next calf crop.

This fall, MU Extension regional livestock specialists say sellers are uncertain about expected prices. Calf prices and beef futures markets dropped sharply this year from record prices two years ago.

Specialists remind sellers that many more bidders know the value of beef genetics. They pay more for quality.

However, Eldon Cole, MU Extension specialist at Mount Vernon, says, “It could be a buyers’ market.”

MU Extension leads the nation in heifer development education, which has been underway since 1997. Buyers from 19 states have bought heifers at SMS sales.

Kendra Graham, MU Extension specialist, Farmington, is surprised by the number of phone calls from potential out-of-state buyers.

“Repeat buyers bid more for Show-Me-Select,” Patterson said. “They know what they are buying.”

Bidders get data as well as heifers. Sale-day catalogs give genetic details such as sire EPDs (expected progeny differences) on sale offerings.

Major emphasis in the early years was on adding calving-ease EPDs. Herd owners almost eliminated need for cesarean-section births of large calves. Veterinarians like that.

With calving ease, buyers cut death losses of heifers and offspring at calving. Along with calving ease, breeders add EPDs for carcass traits such as marbling.

With fixed-time artificial insemination (FTAI), all cows can be bred on the same day. That shortens calving seasons. Producers spend fewer nights checking calving.

Best of all, they find fewer heifers need assistance at birth.

SMS is more than genetics, Patterson said. Good health and nutrition help heifers reach puberty earlier. Pre-breeding exams cull heifers that can’t calve. That groups calving dates and boosts calving rates as well. Dead calves hurt herd profits.

In recent talks at beef meetings, MU Extension economist Scott Brown says growing quality beef gives risk management. Carcasses grading USDA prime sell for more than lower-quality grades. Also, prime quality smooths price volatility.

Information on the SMS program and sales can be found at agebb.missouri.edu/select.

Patterson and MU graduate students did research on heifer management and breeding at the MU Thompson Farm, Spickard. The farm, part of the MU College of Agriculture, Food and Natural Resources, maintains a commercial Angus-based beef herd.
