Trichomoniasis is a bovine venereal disease that can cause substantial reproductive and economic loss in cow-calf operations that use natural service. Many states, including Louisiana, now have regulations on movement of bulls to prevent the spread of trichomoniasis.
Performing breeding soundness evaluations on herd bulls is a sound investment for beef cow-calf operations. A bull breeding soundness evaluation (BSE) is a uniform method of assessing a bull’s likelihood of accomplishing pregnancy in an appropriate number of open, healthy, cycling cows or heifers in a defined breeding season.
Discussion on the importance of good disposition in the beef industry and how to select for it.
Using EPD's for selection and improvement of a beef herd.
An overview of what ultrasound is and what it means for today's cattle producer
Although there’s not an imminent danger, some scientists say a widespread disease or bioterrorism attack could wipe out significant portions of the U.S. farm animal population. That's where the National Animal Germplasm Program comes in.
To determine the effectiveness of short-duration, rotational grazing systems for cattle in South Louisiana, a three-year study (Phase 1 of a six-year project), designed to evaluate pasture stocking methods and rates, was initiated in the spring of 1999 at the Iberia Research Station near Jeanerette.
These data suggest that good quality hay fed free choice can meet nutrient requirements during the last one-third of gestation, a period when the nutrient requirements of the cow increase because of the growth of the fetus.
A large segment of the beef cattle industry is adopting expected progeny differences (EPDs) as a valuable selection tool in improving calf productivity.
The southern United States contains almost half of the nation's cow-calf population in the hot/humid Southeast and Gulf Coast areas. Even in more temperate areas of the United States, weaning productivity of Brahman x Bos taurus cows is virtually unequaled.
Based on these results, a cow-calf producer wishing to retain suitable heifers as herd replacements and sell the remaining heifers at weaning can reasonably consider implanting all heifer calves. High-protein creep, limit-fed to suckling heifer calves had no effect on pre-weaning, post-weaning, or reproductive performance in this study.
Estrus synchronization had its humble beginnings in the 1940s when progesterone and pregnant mare serum gonadotropin were administered to cattle at varying stages of the estrous cycle to alter cyclicity. The objective of this study was to evaluate the effectiveness of altrenogest for estrus synchronization of crossbred beef heifers.
The purpose of this report is to compare the performance of two-, three- and four-breed rotational crossbreeding systems and straight-breeds for calf weaning weight per cow exposed and for cumulative weaning weight per cow entering the herd.
In this crossbreeding study, one of the main objectives was to compare straight-bred and composite-sired progeny that vary in percentage of Brahman inheritance.
The purpose of this research was to compare two-, three- and four-breed rotational crossbred females produced in generation 4 of a long-term crossbreeding study to Brahman first-cross cows for calf performance in a commercial cow-calf setting in South Louisiana.
Although there’s not an imminent danger, some scientists say a widespread disease or bioterrorism attack could wipe out significant portions of the U.S. farm animal population. That's where the National Animal Germplasm Program comes in.
Because Brahman cattle have been associated with poor temperament and meat quality, researchers have been looking at crosses involving the tropically adapted Brahman breed and comparing them to crosses involving another tropically adapted breed, Africaner.
