THE WEIGHT GAIN IS REAL. Go ahead, blink.

A deworming with LONGRANGE® (eprinomectin) can help keep parasites from eating into your profits. If you used a conventional dewormer like CYDECTIN® (moxidectin), SAFE-GUARD® (fenbendazole) or in combination, your cattle are probably already reinfected with parasites. That’s because conventional dewormers only last 14 to 42 days and SAFE-GUARD has no persistent effect. Only LONGRANGE delivers up to 150 days of parasite control in a single treatment.1,2 When you look at the benefits of season-long parasite control with LONGRANGE – you’ll see you have a lot to gain.

Use LONGRANGE on your cow/calf operation and see the difference for yourself.

Environmental Hazards Not for use in cattle managed in feedlots or under intensive rotational grazing because the environmental impact has not been evaluated for these scenarios. Other Warnings: Underdosing and/or subtherapeutic concentrations of extended-release anthelmintic products may encourage the development of parasite resistance. It is recommended that parasite resistance be monitored following the use of any anthelmintic with the use of a fecal egg count reduction test program. TARGET ANIMAL SAFETY Clinical studies have demonstrated the wide margin of safety of LONGRANGE® (eprinomectin). Overdosing at 3 to 5 times the recommended dose resulted in a statistically significant reduction in average weight gain when compared to the group tested at label dose. Treatment-related lesions observed in most cattle administered the product included swelling, hyperemia, or necrosis in the subcutaneous tissue of the skin. The administration of LONGRANGE at 3 times the recommended therapeutic dose had no adverse reproductive effects on beef cows at all stages of breeding or pregnancy or on their calves. Not for use in bulls, as reproductive safety testing has not been conducted in males intended for breeding or actively breeding. Not for use in calves less than 3 months of age because safety testing has not been conducted in calves less than 3 months of age.

of Directions. We’ve worked with presenters from the 2017 Cattlemen’s College to provide you with the latest management information and ideas to allow you to move your herds forward. The consumer ultimately drives the market and prices for the beef we produce, and we must always keep their demands in mind when we make our decisions each spring. That’s why we focus on innovation in the spring magazine. It’s because of this dedication that beef continues to be the protein of choice for consumers and we must never lose that focus. Whether it’s new ideas about selection or better information about grass and forage management, the idea is to provide you with the information that allows you to move your herd forward, protect the resources with which we’ve been entrusted, add to your bottom line and produce the beef that consumers want to purchase.

Letter from the President Craig Uden Every spring we have an opportunity in this business to choose a direction, and that applies to our herds, businesses and our industry. It’s the time when we see new calves hit the ground across a large portion of the country, we make breeding decisions and some of us take to the fields to plant new crops. It’s a time for renewal and it’s a time of year when there’s a strong sense of optimism among cattlemen and cattlewomen. The uptick in the market this spring has added to that optimism, and frankly, it’s an improvement that we needed to see after a historic sell-off in cattle markets. But, it also serves as a good reminder that no matter how much we might want to be in control of cattle prices, they’re subject to many forces outside of our control. There are things we do have the ability to affect, though, and one of those items includes the management and quality of our animals and the beef they produce. That’s the focus of this edition 6 NATIONAL CATTLEMEN

I once sat in the audience while Joann Smith admonished a room full of beef producers for failing to listen to the consumer, and it’s a speech I have never forgotten. In fact, Smith’s words stuck with me and helped to guide my management decisions and leadership philosophy since that time. As producers, every single member of the beef community owes it to our communities to take care of the air, land and water we manage. We owe it to our family to make decisions that guide us to profitability and we owe it to our animals to ensure we’re making the right decisions for their health and welfare. And finally, we owe it to the consumer to make sure we’re producing beef that’s safe, wholesome and meets their demands, even as those demands change over time. In my mind, sustainability encompasses those four pillars but it’s also about identifying the issues we face and continue to learn as we make improvements in our operations over time. I’ve been thinking a lot about sustainability as NCBA president. I think about the sustainability of our industry and what we can do to improve it and make sure it’s prospering for the next generation as they begin to take on management and leadership roles. That’s why publications such as this one are important to us at NCBA. It’s why we’ve served the beef community since 1898 and it’s what guides the volunteers and staff who work on your behalf each day. SPRING

We fight to make certain rural voices are represented at the tables which are increasingly dominated by urban decision-makers. We remain committed to the ideas and principles that our country was founded upon and we’re there each day to be certain that beef competes on a level playing field in the United States and abroad when market and trade rules are being considered.

Letter from the CEO Kendal Frazier NCBA serves two distinct purposes within the beef community. We are, and have been since our beginning, a membership organization which serves to insulate our dues paying members from the heavy hand of government. We are also a major contractor to the Beef Checkoff Program. This branch of NCBA serves every checkoff paying member of the beef value chain. From cow-calf producers to importers and every segment between, we contract to do the work that must be done to keep beef at the center of the plate in the marketplace. This work is done knowing that beef competes against intense competition from pork, poultry and other meal choices. As a membership organization, we take our direction from our individual members and state cattlemen’s associations, which direct the policies of NCBA and the work of our staff in both Washington, D.C., and Denver, Colo. As a

As a proud contractor to the beef checkoff, we do the difficult work that must be done for the beef community. The work we do as a contractor is essential and valuable to our business. Third-party research shows that every dollar invested into the checkoff returns $11.20 to cattlemen and women. The work on beef promotion and research is also directed by grassroots members of the Cattlemen’s Beef Board and the Beef Promotion Operating Committee. These volunteer cattlemen and women are tasked with addressing the needs of our industry today and anticipating the changing demands of future consumers in an effort to ensure beef remains competitive against other proteins. Regardless of the project or the issue, each NCBA volunteer leader and staff member goes to work each day knowing that the work they do improves the future for beef producers. Sometimes there are immediate results, other times those results are delayed, sometimes for years. However, we all remain committed to the goal of a brighter future for beef and the beef community. I’m proud to work with a strong and committed team and I’m proud of the work we do each day for the beef community as a membership organization and as a proud contractor to the beef checkoff. As you begin making business of your spring work, we

hope you’ll take a moment and give a little back to your community in one form or another. Volunteer at your

church, read to a child or serve a leadership role in an

organization that makes a difference. It’s that spirit that separates the communities where beef producers live

from the rest of America. It’s the same spirit that makes America, and beef producers in particular, so great.

Managing Forages to Meet Beef Cattle Nutrient Needs By Dennis Hancock, Ph.D.1, and Beth Kegley, Ph.D. 2 1

Department of Crop and Soil Sciences, University of Georgia 2 Department of Animal Sciences, University of Arkansas

Summary The most cost-effective way to meet beef cattle nutritional needs is generally to ensure that the forage provided to the animals approaches or exceeds the nutrient needs of the cattle being fed. The challenge is consistently producing forages that provide sufficient protein, energy, and mineral content. Management factors, such as the forage crop’s maturity and the species of the forage provided to the animal, has a significant impact on the crude protein, digestible energy content, and mineral concentration. This paper describes some of the management factors that influence the nutritive value and mineral content of forage.

Background In most beef cattle enterprises, 60 percent or more of the total cost of production is tied up in feed

costs. The forage component consists of the largest proportion of that cost. The use of forages that approach or exceed the nutrient needs of the cattle being fed will minimize the total cost and increase profitability. The challenge is consistently producing forages that provide sufficient protein, energy, and mineral content. This article discusses some of the management factors that influence forage quality and mineral content.

Discussion Management Factors That Affect Forage Quality The most critical management factors and their relative importance with regard to forage quality are listed in Table 1. Certainly, there are many additional factors that affect forage quality. However, following the recommendations for each

High Forage Species Moderate Forage Utilization Moderate Variety Moderate Storage Moderate Rain Damage Moderate Heat Damage Low Fertilization www.BeefUSA.org

Recommendations Cut the forage in the late vegetative or early reproductive stages of growth. See the harvest recommendations in Table 2 for detailed information on individual species. Use a high-quality forage species that persists and can be produced economically in your environment. Species resistant to drought and temperature extremes should be used. Grazed forage is generally higher quality than conserved forage (i.e., barn, hay silage, etc.) However, animal selectivity may reduce overall forage utilization compared to mechanically harvestedsystems. Use varieties that have proven to provide a good balance of high quality and high yields. Select disease and insect resistant varieties. Protect hay bales from rainfall and weathering during storage (i.e., barn, tarp, etc.). Properly pack and exclude oxygen from forage that is being ensiled. Avoid cutting if significant rainfall (> 0.50 inches) is predicted during curing, but take care to avoid allowing forage to become overly mature. Dry forage to the appropriate moisture for making hay (Round: 15%; Square: 18%) and store in a manner that allows adequate ventilation. Maintain integrity of oxygen barrier in silage storage. Fertilize based on soil test recommendations and at recommended times to sustain CP/mineral concentrations in the forage and to maximize vegetative mass in the standing forage. NATIONAL CATTLEMEN

Continued from page 12 Because of the effects of advancing maturity on

quality, it is critical to harvest the crop whenever the forage reaches the recommended stage for harvest. Table 2 lists the maturity stages that should be

targeted for some of the major forage crops. Delaying

a harvest beyond the recommended maturity stage will result in forage that is less digestible and

much less capable of being consumed at a high

rate of intake. Harvesting slightly earlier than the recommended maturity is an option and may be advisable to avoid weather-related risk.

In the spring after establishment, allow the first cutting to reach mid-bloom. Harvest if forage growth ceases because of hot or dry weather. If the variety rarely gets taller than 14 - 15 inches, take the first harvest at 12 inches. Harvest if forage growth ceases because of hot or dry weather. When grown with a grass, cut at the correct the correct stage for the grass. If the boot-early head stage is missed, take the first harvest at the dough stage. Harvest if forage growth ceases because of hot or dry weather. When grown with a grass, cut at the correct stage for the grass.

Management Factors That Affect Mineral Content

Like its impact on protein and digestible energy content, plant maturity is a crucial factor affecting mineral content in forages. Actively growing plant tissue generally has higher concentrations of P, Mg, and K. Mature forage generally has lower Co, Cu, Fe, Mo, and Zn. In contrast, the Ca levels are usually not affected by maturity.

Forage species also vary in mineral content (Table 3). Legumes generally have higher concentrations of Ca, Mg, K, Cu, Zn, and Co than grasses, while grasses are generally higher in Mn. However, mineral content in the various forage species may also be substantially affected by the soil in which they are growing. Soil fertility has a major impact on mineral

nutrition. The status of the soil with regard to the mineral in question would certainly have an impact on the forage’s mineral concentration. Soil type and the parent material of the soil can influence the nutrient concentration that is observed. Further, soil pH that is too high or too low can influence mineral content, particularly the micronutrients. Higher pH tends to increase Se and Mo, but may actually reduce Cu, Co, Mn, Fe, and Zn concentrations.

Further, fertilization that stimulates plant growth can increase the concentration of the mineral(s) being added, but it may lower other minerals’ concentration. Fertilization in excess of the plant’s need may result in high or toxic concentrations developing in the forage. Because of the variability induced by different soil fertility and forage management tactics, it is important that the forage mineral content be regularly monitored with a forage test.

real task may be getting the industry to incorporate the trait of disease susceptibility into beef cattle selection indices and selection decisions. One issue is that not all beef breed associations have economic selection

indices, which would leave the value determination

of BRD susceptibility up to the individual breeder. A recent economic analysis on a terminal sire selection index showed that BRD had a high economic value – almost as high as hot carcass weight - meaning

selection against BRD incidence should get a high economic weighting as its economic importance is significant to overall profitability (Table 1).

Conclusion There is clearly value in selection for cattle health. If producers were able to make a 1-2 percent

improvement in BRD susceptibility by selecting for cattle using an accurate BRD susceptibility genetic

Purina® All Seasons™ Cattle Nutrition Program

First-calf heifers: friend or foe? Calving a first-calf heifer out and then trying to get her bred back in 60 days can be a challenge. It’s a critical timeframe that can make or break a heifer’s future in the herd. Help put your heifers on the path to success by evaluating your nutrition program. A heifer nutrition program should: 1. Support more heifers bred Your herd relies on developing heifers that are fertile, milk well and have longevity. But, heifers are still growing, developing their next calf and may also have a calf at side. You can’t assume they have it all covered. Your heifers need a boost. The nutrition you provide heifers plays an important role in getting them bred and rebred. Quality nutrition during all three trimesters of a heifer’s pregnancy can also maximize the genetic potential of the resulting calf. The Purina® All Seasons™ Cattle Nutrition Program is designed to support more heifers bred in the first 60 days postcalving. 2.

When forage availability changes throughout the year, choices within the Purina® All Seasons™ Cattle Nutrition Program do too. Plus, Accuration® protein supplements with Intake Modifying Technology® encourage snack eating, causing heifers to be able to eat more forage and get more out of the forage they eat.

Bradley 3 Ranch is a registered Angus and Charolais operation located in the Texas panhandle. Despite sparse forage and extreme weather conditions, cattle are expected to be productive. Replacement heifers are no exception.

Weather-resistant Wind and Rain® Storm® minerals provide another layer of convenience, ensuring your mineral investment isn’t being washed away. 3. Give you confidence You should be confident in your heifer nutrition program. You need to know you’re doing what’s best for your cattle and operation to move it forward to the next generation. Over 1,800 Proof Pays feeding trials have been completed nationwide on operations just like yours, proving that solutions within the Purina® All Seasons™ Cattle Nutrition Program work. If you need your own proof, you can complete an on-farm feeding trial and let your animals speak to the results. Talk to your local Purina representative, or visit ProofPays.com to start your feeding trial.

“Replacement heifers are our future, and we’ve found that nutrition is a big part of developing them. Every bit of performance that we can get out of those animals pays,” says James Henderson, part owner. “Producers in many areas spend a tremendous amount of time hauling forage and feed to their cattle. It takes a lot of labor and resources to do that. We need a system that works for our cattle and us.” The Purina® All Seasons™ Cattle Nutrition Program has flexible solutions designed to support productive heifers.

Grazing management that removes too much leaf area weakens forage plants. Plants cannot capture

enough sunlight for regrowth, and will sacrifice roots

and energy reserves to support essential leaf regrowth. With fewer roots, plants cannot fully access soil

moisture and nutrients. Tate cautions that weakened

forage plants can be displaced by undesired or invasive species. As Rogers notes, poor grazing management on wet, moderate to heavy textured soils will also often compact the soil and limit water, root, and

nutrient penetration. This is a dangerous cycle that will not sustain livestock production.

outcomes. Management that supports growth and Examining the structure of a soil aggregate for evidence of compaction on a rangeland pasture.

in Rangeland Watershed Science at University of

California – Davis. Echoing earlier emphases, Tate notes that ranchers must manage the intensity and timing of grazing, as well as — equally important — rest from grazing, to 1) optimize forage and

livestock harvest; 2) meet forage plant requirements for growth and vigor; and 3) mitigate potential

negative impacts on soils and the environment. He points out that optimal cattle performance in rangeland systems depends upon abundant,

nutritious forage – which in turn depends upon healthy forage plants with enough leaf area to

capture sunlight, and many deep roots to access abundant soil moisture and nutrients.

vigor of desired forage plants, as well as root and

water penetration throughout the soil, will result in:  Optimal forage production and quality  Optimal animal performance

 Pasture resilience to drought, weed invasion, and other stresses  Return on investments in herd genetics, reproduction, health, supplementation, and infrastructure

 Healthy and productive soil and environmental conditions Many grazing strategies can sustain forage plant vigor and soil health. Tate emphasizes that continuous and rotational grazing strategies at moderate stocking rates in rangeland systems can sustain high levels of soil function, forage production, and livestock performance. However, recent surveys of 765

California and Wyoming ranchers show that two-

thirds of respondents use extensive rotational grazing strategies, with livestock movements every few weeks and moderate stocking rates — ranchers see on-theground and on-the-hoof benefits from pasture rest and rotation of grazing animals.

Tate advises that underperforming rangeland

pastures should be investigated, particularly in heavy soils commonly grazed during wet periods. Grab

a shovel, and dig a pit 1 foot deep by a couple feet long. Look 3 to 6 inches below the surface for a

band of compacted, platy, massive soil with little

root penetration. Look for fine plant roots stacked on top of this layer. Presence indicates you might

have a “cow-pan”. For additional information on this and other grazing management issues, soil, forage,

and livestock expertise is available within university Cooperative Extension, as well as through NRCS. In most cases, Tate assures that small adjustments

in intensity and timing of grazing will allow rooting

and natural soil processes to break down compaction and improve soil structure within a few years –

allowing increases in water infiltration, soil health, forage and cattle production.

Conclusions Grazing management in pasture and rangeland systems is sustainable when it promotes profit as well as environmental health over the long term. Speakers in this Cattlemen’s College

session asserted what ranchers have known for

generations – if you take care of the land, it will take care of you. Optimizing grazing involves

appropriate stock densities, duration of grazing,

and adequate non-grazing rest periods for plants. Soil health is a key component of a sustainable operation. Rogers notes the importance of

keeping the soil covered to maintain temperatures for microbial activity and prevent erosion.

Effective management of aboveground resources

benefits the belowground community, and Rogers mentions the importance of microbial activity for aggregate formation to improve soil structure.

Future of the Cattle Feeding Industry in the United States By Galen E. Erickson1 1

Nebraska Cattle Industry Professor of Animal Science; Beef Feedlot Extension Specialist Department of Animal Science; University of Nebraska-Lincoln

Introduction The U.S. beef industry is the most intensive beef production system in the world, and as a result,

the most efficient. In this case, efficiency refers to the number of cows in production relative to the

tons of beef produced. Intensive beef production is often thought of in terms of feeding cereal grains. However, many producers and consumers do not

recognize the importance of forage in intensive beef

production systems. We estimate that approximately 80 to 85 percent of the feed required to raise a steer or heifer for market is forage. The new NASEM (2016) Nutrient Requirements of Beef Cattle

estimates that approximately 80.8 percent of feed

required is forage and less than 10 percent is grain. The reasons that an overwhelming majority of the

feed inputs are forage include the fact that there is a cow that is fed forage for a year in order to produce a market animal. The proportion of forage required in beef production systems is further influenced by

the average age of grain finished beef, average days in feed yard systems, and reproductive and survival rates in the industry. With increased intensity

of cattle feeding, many environmental issues are actually improved relative to producing beef. However, there are challenges as well.

While it is difficult to predict the future, this

paper will focus on recent trends in key areas that

www.BeefUSA.org

are expected to continue and therefore help predict the future of the feeding industry in the U.S. The key areas that need to be considered are:

1) Geographic location of the feeding industry

2) Cattle characteristics 3) Nutrition advances

4) Health issues and challenges

5) Marketing

6) Environmental issues 7) Technology 8) People

The largest cattle feeding states are Nebraska,

Texas, and Kansas but cattle are fed in many other Plains and Midwest areas. There are pockets of

cattle feeding areas including the Pacific Northwest and Southwest regions. The question is, where will

cattle feeding locations be in the future? In the old days, the Midwest region fed the most cattle and

then there was a transition to the Southern Plains

due to climate, cattle availability, and inf rastructure to translocate feed resources. With distiller’s

byproducts and housing changes, some transitions back to Midwest feeding has occurred in recent

years. While it is unclear where more cattle will be

fed in the future as the cattle industry expands and contracts, clearly water and packing capacities will influence these decisions.

may look like. We are experiencing record quality

cattle bigger results in a more efficient beef industry.

difficult part is to predict what a future carcass grades (75 percent choice or above) and record

carcass weights. The trendline for the past 45 years has been a linear increase in carcass weights of 5

lb/year for steers and 6 lb/year for heifers. While

many view this as a challenge for the industry and

others suggest cattle can’t get bigger, clearly there are some efficiencies to larger carcasses and cattle have

been selected to be bigger and have been fed longer to make carcasses heavier. Without changing the

market pricing approach for fat cattle (price slide or

greater penalties for big cattle), this trend is unlikely to change. From an individual feeder perspective,

bigger carcasses generate greater revenue and cost

of gain is lower than finished price, even at the end

of the feeding period. As a result, the individual has an incentive to make cattle bigger. Suggesting that

feedyards should market cattle at lighter weights is counterproductive to their economic sustainability

in today’s market. Selling cattle on a carcass weightbasis instead of a live-basis only encourages cattle to be fed longer as the cattle are depositing a

larger proportion of gain on the carcass relative to

54 NATIONAL CATTLEMEN

Additionally, the more beef supplied by making

About 70 percent of the feed and 50 percent of the cost of a finished animal is the cow.

Nutrition programs are very advanced, and are based on research designed to optimize how cattle are fed. One of the biggest changes in diets in the past 20

years has been the popularity and economic incentive to feed corn byproducts such as distillers grains, corn gluten feed, or Sweet Bran. Feeding byproducts is

not a new concept for beef producers. Corn grain is

still the most important ingredient in feed yard diets. There has been increased interest and adoption of

steam-flaking in Nebraska, whereas the technology

is commonly used in the southern plains. New corn

hybrids, new byproducts, or changing how cattle are fed in terms of additives, technologies, adaptation programs, bunk reading, and overall nutrition

programs is exciting but changes will be relatively slow depending on the adoption rates of new improvements based on research.

for feed yard managers and often will take much of but the most time is spent marketing finished cattle. One of the most widely debated topics today is

whether prices are suppressed for fat cattle due to

marketing arrangements. Marketing arrangements, such as formula pricing and captive supplies, are

desirable by some because it is less expensive and

time consuming for the feed yard manager. On the other hand, if all cattle are priced relative to some plant or area average price, then questions arise

on whether the smaller and smaller percentage of

cattle that are negotiated for price are sufficient to set the market price for the majority of cattle that are not negotiated at the time

of sale. It is not clear what the

minimum number of cattle need to be negotiated to obtain a fair

or maximal cattle price. There are also dramatic regional differences with the southern plains states

The feeding industry has very high expectations for businesses are smart, tough, innovative, and often independent individuals. Most managers do not

enjoy all the normal challenges related to managing

employees. As a generalization, the feedyard industry will need to do a better job of attracting talent,

attracting laborer employees, and then a better job of training, retaining, and firing people than in

the past. The opportunities for young people are

obvious but taking advantage of those opportunities requires young people who work hard, can work with people, understand a risky, complicated

business, and are willing to work long hours in

Developing Heifers For the Long Haul By G. Cliff Lamb1, Pedro L. P. Fontes2, Nicky Oosthuizen2, Carla D. Sanford2 1

Introduction Most beef producers replace up to 20 percent of their mature cows each year with heifers. Those heifers represent the future genetics and profit potential of the operation. However, beef producers today are faced with several decisions that impact the

productivity of their operations, of which selecting

replacement beef heifers is critical to sustaining an

ever-decreasing profit margin. The unique challenge that each cow/calf producer is faced with is that the

selection of heifers now will affect the profitability of an operation for at least a decade. The mindset for a

cow/calf producer needs to take into account how the heifers that are selected now, as replacements, will

affect their operation ten to twelve years from now. This mindset is entirely different from the feedlot industry or even the poultry and swine industries where turnover and generation intervals are far

shorter; thus, in these industries an error in selection or management can be noticed and remedied at a far faster rate.

It is fairly simple to purchase heifers at a discounted price either from a sale barn, neighbor or even a

heifer replacement sale. However, it is imperative to keep in mind that not any heifer will become a profitable cow. Many factors dictate how an

individual cow performs in a given management

system, and each producer should evaluate the effects of those factors on the potential profitability of 63 NATIONAL CATTLEMEN

their cows. The genetic origin (i.e. breed and color), management techniques from diet to reproduction,

alliances, marketability of heifers, and economics are

all factors that a producer needs to take into account when purchasing or developing heifers.

The efficiency of post-weaning development of heifers has a major impact on the overall

profitability of cow-calf operations. To ensure

satisfactory performance during the first breeding season, replacement heifers must be subjected to an adequate development program. A program

should provide proper conditions for heifers to

conceive, maintain full-term pregnancies, calve

without assistance, wean a healthy calf, and conceive again as first-calf heifers. Knowledge of the basic physiology underlying heifer performance and

the available breeding preparation strategies is important. This awareness allows producers to

adjust their replacement heifer system and increase the economic returns of their operations.

Age At Puberty, Nutrition, And Target Body Weight Gain Age at puberty is a major factor that influences

reproductive success of beef heifers. Ideally, heifers should reach puberty approximately 60 days

before the beginning of their first breeding season,

increasing their chances of becoming pregnant and allowing them to conceive earlier in the season.

The timing of first conception is also important to the overall productivity of a heifer. Females that

calve at the beginning of their first calving season have been shown to have a greater probability of

pregnancy in the subsequent breeding season when

bred as first-calf heifers (Patterson et al. 1992). Cows that calve in the beginning of the calving season

were also shown to wean heavier calves (Rodgers et

al. 2012) and stay productive in the herd for a longer period of time (Cushman et al. 2013). Therefore,

increasing the proportion of beef females that calve

earlier can increase the economic returns of cow-calf producers (Rodgers et al. 2012; Lamb et al. 2016).

Management strategies that lower the age at which

heifers reach puberty can have a great impact on the reproductive efficiency of beef heifers and positively affect overall profitability for the producer. Breed is an important aspect that must be

considered when preparing heifers for breeding.

www.BeefUSA.org

Most U.S. heifer herds are composed of Bos taurus

breeds in which heifers are bred to calve at 2 years of age. However, in the southern states, such as

Florida, more than 50 percent of heifers calve at a later age (Day and Nogueira 2013). This is a

result of a greater presence of Bos indicus genotype in these particular herds. Bos indicus-influenced heifers reach puberty later. Producers generally

manage their herds to achieve parturition at 30–36

months of age for this reason. However, Bos indicus heifers can be developed to calve at 2 years old if they are properly managed. The use of nutrition strategies and pharmacological treatments that

accelerate puberty allows producers with Bos indicus cattle to breed heifers to calve at 24 months (Day and Nogueira 2013).

The period of time that precedes puberty is

called the peripubertal period. From an endocrine standpoint, this period is characterized by a

However, dominant follicles fail to ovulate during feedback of estradiol on GnRH secretion. The

negative feedback of estradiol decreases as puberty approaches, allowing the secretion of GnRH and LH to increase. Increased LH activity stimulates final follicular growth and maturation of the

dominant follicles, therefore increasing estradiol

concentration to a threshold that activates the preovulatory LH surge and causes ovulation.

The mechanisms that control the decrease in the

negative feedback of estradiol are not completely understood. Nevertheless, it is well documented that nutrition is a key factor that influences

age at puberty and, consequently, reproductive performance of heifers (Patterson et al. 1992; Day and Nogueira 2013). An adequate plane

capable of providing sufficient energy and protein before the beginning of the breeding season.

Pelvic Area Measurements and Reproductive Tract Score Dystocia is a constant concern in heifer

management. The incidence of dystocia is increased in heifers that are not fully grown at the time of first calving. Heifers with small pelvic areas are

more likely to have greater calving difficulty. The measurements of pelvic area can help producers

determine which animals are ready to be exposed to breeding and decrease the risk of dystocia by

helping them select animals with larger birth canals (Troxel 2011).
