(2020-04-23)The consistency of instruction between various sections of introductory courses is a concern in higher education, along with properly preparing students to enter careers in industry. The study was conducted at Texas A&M ...
-
(2021-07-13)Ruminal fermentative processes allow cattle to consume a variety of feeds that are converted into human edible product, resulting in methane (CH4) as a byproduct. Feed additives, like monensin, can be added to cattle rations ...
-
(1985)The emphasis of this study was to develop a procedure for detecting the adulteration of nonfat dry milk with whey protein products. It was necessary to determine the effects of mastitis and heat processing as these are two ...
-
(2012-10-19)Little is known about the adaptation of livestock to repeated transport. This study determined how repeated transport affected calf feed intake, plasma cortisol (CORT), post-transport behavior, and the expression of ...
-
(Texas A&M University, 2007-04-25)Activity of group-transported horses was evaluated during onboard rest stops to determine if horses derive meaningful rest. A single-deck semi-trailer separated into three compartments was used for all shipments. In ...
-
(Texas A&M University, 2004-11-15)The effects of conjugated linoleic acid (CLA) on lipogenesis and preadipocyte proliferation in young pigs were evaluated in two separate experiments. The first compared dietary effects of linoleic acid, beef tallow, and ...
-
(2012-07-16)The objective of this study was to evaluate the effects of heat stress and varying levels of milk replacer on dairy calf performance. Holstein bull calves ≤ 2 d of age were randomly assigned housing, outside under a covered ...
-
(2014-11-25)Eighteen Quarter Horses were utilized in a randomized complete design for a 28 d experiment to evaluate age-related effects on inflammation and cartilage turnover after induction of a single inflammatory insult using ...
-
(2020-10-26)Reproductive inefficiency is a critical barrier maximizing profitability and sustainability of cattle industries. While intensive management strategies have provided crucial information regarding the amount of pregnancy ...
-
(Texas A&M University, 2005-08-29)The objective of this study was to determine concentrations of amino acids and polyamines as well as nitric oxide (NO) and polyamine synthesis in the ovine conceptus (embryo/fetal and associated placental membrane). Ewes ...
-
(2010-07-14)In the stallion, inconsistent sexual behavior and variable semen quality are common. This reproductive variability has been attributed to differences in circulating hormone concentrations. In order to further examine this ...
-
(2016-12-06)Methylation of the carbon 5 position of cytosine is a common epigenetic mark in vertebrates, and has been associated with male infertility. Methylation can be affected by environmental changes in utero and our long-term ...
-
(Texas A&M University, 2005-11-01)Records of embryo production in Red Brahman donor cows (n=50) and F1 recipients (n=531) were evaluated from the collection day to the birth of the embryo produced. The effects of the sire of the donor and the embryo, ...
-
(2014-08-13)Anterior gradient homolog 2 (AGR2) is a proto-oncogene that encodes a secreted protein with biological roles in cell migration, differentiation, and growth, and is also implicated in epithelial barrier function and integrity. ...
-
(2010-07-14)In Experiment 1, 12 cyclic mares were assigned randomly to one of two groups (n = 6/group): 1) Control, saline; and 2) GnRH, 100 mu g/h. Between 3 and 6 d after ovulation (Day 0), Alzet osmotic minipumps (Model 2ML1) ...
-
(2015-08-11)The primary objective of this study was to determine the relationship of anti-Müllerian hormone (AMH) to ova production in various breeds of cattle in an embryo transfer program. Factors evaluated included breed type, age, ...
-
(2017-09-05)The studies described herein were designed to characterize measures of immune responsiveness in weaned Brahman calves, breeding bulls and cows. Experiment 1 included 55 weaned bull and 57 weaned heifer Brahman calves. ...
-
(2010-10-12)Nisin is a naturally occurring food antimicrobial that inhibits many Grampositive pathogens, including Listeria monocytogenes, a bacterial pathogen responsible for ~500 deaths in the U.S. annually. Factors known to counteract ...
-
(2019-07-26)Residual feed intake (RFI) is an ideal trait for use in selection programs to improve feed efficiency in beef cattle, as it quantifies between-animal variation in DMI that is independent of body size and productivity, to ...
-
(2014-07-17)The objectives of this study were to evaluate the use of fecal NIRS profiling and the n-alkane labeled supplementation method for the prediction of voluntary intake in beef cattle for the identification of animals divergent ...
