Substantial research has been conducted contributing to the traditional guidelines of developing heifers to 60 to 65% of mature body weight at time of breeding. In general, studies evaluating different postweaning rates of gain or target weights have used either different amounts of feed, or different types of feeds varying in energy and/or protein content to obtain differences in rates of growth....
Proper planning prior to calving season can mean more live calves. Excessive losses can mean the difference between a year’s profit or loss for a beef producer. Before the calving season, it is a good time to put together the supplies and equipment that will be needed to assist heifers and cows that need help at calving time....

The nutritional quality of feeds and forage can have a tremendous influence on the reproductive performance of cattle. Although reproductive failure may occur for several reasons, management and the environment are often important contributing factors....
Fall means gathering the cattle and assessing the summer grazing season. If not already done, calf vaccinations should be completed in preparation for weaning and marketing. Some areas already may have weaned because pastures are short....
Leptospirosis is a zoonotic disease (affects both animals and people) that can cause significant economic losses in a number of domestic species. Vaccination is the key to preventing leptospirosis infections....
The two-year-old first calf heifer that needs to rebreed may be one of your most valued females, but she can be one of the most costly and one that requires more management. According to Tom Geary with the USDA Ag Research Service, she is the most valuable and most expensive animal in the herd....
Introduction Evaluating the reproductive ability of breeding stock is crucial for cow/calf operations. Cattle that have irregular estrous cycles often have difficulty becoming pregnant, thus increasing the total days open and reducing the total pounds of calf weaned per cow exposed....
Trichomoniasis or “trich” for short is a venereal disease of cattle that causes infertility, open cows, and abortions in cows and heifers. It is caused by Tritrichomonas fetus, a small protozoan parasite of the reproductive tract of the bull and cow....
AUSTIN, Texas – September 16, 2008 – Just two weeks since announcing a partnership with Texas Tech University System (TTUS) to license and develop the universities’ intellectual properties, LGE Execs has created a company to develop its first product out of the TTUS laboratories....
Over the past 15 years, 30 different research trials have been conducted that examine the impact of supplemental fat on reproductive performance of beef and dairy cattle. Fats (or lipids) have been fed before and after calving and during the breeding season....
As fall calving begins, the North American Limousin Foundation (NALF) encourages its members to score their cows’ teat sizes and udder suspensions so the data can help guide future selection decisions....
One of the most challenging aspects of spring calving is trying to determine when to calve to maximize reproductive rate. Reproductive efficiency in a cow herd is most accurately measured by the term "percent calf crop weaned" which is calculated by dividing the number of calves weaned by the number of cows that were in the cow herd when the breeding season began the previous year....
Rebreeding performance of the first calf heifer has major economic consequences. This classification of breeding animal is often the most challenging to manage for reproductive efficiency, primarily because this animal is not only subject to the stresses of calving and lactation for the first time but she is also still growing....
Occasionally, beef cattle develop problems with prolapses near the time of calving. A prolapse can be basically defined as an abnormal repositioning of a body part from its normal anatomical position....
Artificial insemination (AI) is one of the most effective tools available to enhance the productivity and profitability of beef cattle production systems. Even though this tool has been commercially available for more than 65 years, it is still dramatically underused in today's beef herds....
Cow-calf producers have been blessed with high calf prices over the past several years. However, input costs have also gone up. Today, producers have to face higher feed costs due to grain prices, higher fuel prices, higher repair costs, and higher interest costs....
By Martha Hollida Garrett Fall bull sales are just around the corner and cowmen are beginning to think about the type of bull they need and will purchase. In most cow-calf operations, bringing a new bull into the herd is the primary way of making genetic improvement and many of these new bulls are yearlings....
Introduction The selection and development of replacement beef females is critical to the performance of the entire beef operation. Selection of replacements at weaning, and the subsequent management given to yearlings and two-year-olds, can affect performance well into their years as mature cows....
Weaning calves is a ritual for cattle producers and it’s a critical step to having that calf reach its potential and make a profit. Fence-line weaning is a process that is gaining ground and a helpful tool for weaning....
