Previous research suggests that Bos taurus taurus cattle (BT) are less feed efficient when fed low-quality forage, produce more methane (CH4), and exhibit lower levels of N recycling than Bos taurus indicus cattle (BI), ...
-
(Texas A&M University, 2005-02-17)Angus - Bos indicus (Brahman or Nellore) reciprocal backcross embryo transfer calves belonging to 28 full-sib families were evaluated for differences in birth weight (BW), gestation length (GL), weaning weight (WW), ...
-
(2019-05-21)Bovine Viral Diarrhea Virus (BVDV) is a component of bovine respiratory disease complex, which has been reported to cause the largest loss in productivity in feedlot cattle in the U.S., with annual economic losses in excess ...
-
(2009-05-15)Objectives were to determine: 1) whether estradiol benzoate (EB) provides a superior alternative to GnRH for synchronizing emergence, growth and maturation of a new follicular wave for fixed timed AI (TAI) in Bos ...
-
(2014-08-18)The objectives of this study were to estimate heritability of performance traits in Brahman and Brahman-influenced (¼ or ½ Brahman) stocker cattle on cool-season (n = 1,732) and warm-season (n = 1,199) forages. Cattle were ...
-
(2020-01-14)The genetics of longevity in beef cattle production is a critical aspect of efficiency, thus making it an economically important trait. Variation in longevity has been observed between different breeds, and is dependent ...
-
(Texas A&M University, 2005-11-01)Reproductive and weight traits were analyzed for Angus (A), Brahman (B), Hereford (H), and Nellore (N) straightbred cows; F1 NA cows; 3/8N 5/8A cows and quarter blood composite cows (BANH) of the four straightbreds in ...
-
(Texas A&M University, 2007-04-25)Reproductive, maternal and weight traits were analyzed for Angus (A), Brahman (B), Hereford (H), and Nellore (N) straightbred cows; F1 NA; 3/8N 5/8A cows; and four breed composite cows (BANH) at the McGregor Research Station ...
-
(2013-10-31)This study investigated the effects of vaccine type, sire, day, threshold rectal temperature status, and their potential interactions on growth, daily feed intake and daily feed bunk frequency in response to a standardized ...
-
(Texas A&M University, 2008-10-10)Sire and family effects were evaluated for calf growth, udder and teat conformation, and reproduction traits in 2- to 4- yr-old cows from the McGregor Genomics Project. Cows were produced by embryo transfer (ET) and natural ...
-
(2019-05-30)Beef cow reproductive longevity represents the cumulation of a lifetime of fertility and production traits and is an important contributor to a producer’s profitability. Stayability is a component of longevity, and is often ...
-
(2019-11-26)The present research focused on examining how energy restriction, fetal and maternal subspecies (Bos taurus indicus and Bos taurus taurus) interact to impact fetal development events, which can potentially alter nutrient ...
-
(2009-05-15)Correlations between cattle disposition and meat quality were expected to be found, as well as differences in meat quality traits among contemporary groups, sires, and families nested within sires. Temperament effects on ...
-
(2019-06-17)Research has shown the M. Rhomboideus (Rho) from purebred Nellore (Bos indicus, BI) carcasses to be unique in its proximate chemical composition, indicated by increased lipid deposition. Thus, potential for the deposition ...
-
(Texas A&M University, 2007-04-25)Objectives were to: 1) Evaluate the effectiveness of presynchronization with GnRH before the COâÂÂSynch + CIDR protocol with timed AI (TAI) at 66 h in Bos indicusâÂÂinfluenced cattle; 2) Characterize ovarian events ...
-
(2018-02-08)Links between nutrition and reproductive success in heifers are well established; however, achieving a high plane of nutrition is costly, and reproductive success remains uncertain, making heifer development both expensive ...
-
(2015-05-11)Multiple investigations were undertaken to determine the effect of various strategies for improving forage intake, digestion, and ruminal fermentation parameters in Bos indicus and Bos taurus steers. Protein supplementation ...
-
(2010-01-16)Steers (n = 77) and heifers (n = 68) were assigned randomly to one of three treatment groups. Treatment groups were defined as: no implant, implanted twice with trenbolone acetate (Revalor S or H), or implanted twice with ...
