Modification of steer muscle composition and meat quality through age at slaughter, hormonal implants, ractopamine hydrochloride feed supplementation, and breed crosses
DownloadFall 2010
Management systems that enhance carcass yield can increase the efficiency and competitiveness of beef producers, but meat quality should not be negatively affected. Continental or British crossbred steers were finished to either 12 to 13 or 18 to 20 months of age and were either untreated or...

Novel feed enzyme delivery method: Binding exogenous feed enzymes to Bacillus spores to improve enzyme stability and total tract digestibility
DownloadFall 2018
The effects of binding feed enzymes to Bacillus subtilis (strain RK28) spores on enzyme stability and digestion in cattle were studied in comparison to unbound enzymes. Optimal conditions for adsorbing six different enzymes (α-amylase, β-glucanase, feruloyl esterase, phytase, purified xylanase,...

Nutrition of the beef cow during pregnancy influences fetal development and potential changes in phenotype. On average 9-10% of beef cows are below the optimal condition score of 2.5/5 at both pre-breeding and pregnancy tests, indicating potential nutritional stress during gestation (Waldner and...

1981
Thirty-five non-pregnant beef cows in three age classes (< 4 yr, 4–5 yr, and > 5 yr) were allocated at random to two treatments (fed, unfed) soon after weaning in November 1978. On day 1, the unfed group of 17 cows were marketed and the fed group of 18 cows were introduced to grain feeding. After...

Oral Porphyromonas gingivalis Infection Induces Epigenetic Changes that Promote Persistence of Cardiovascular Disease Risk
DownloadFall 2020
In the last two decades, periodontitis has become recognized as a risk factor for cardiovascular disease (CVD), a term that encompasses many circulatory disorders, often underpinned by atherosclerosis. One of the major questions regarding this association has been whether elimination of...

Ovarian and endocrine responses associated with the treatment of cystic ovarian follicles in dairy cows with gonadotropin releasing hormone and prostaglandin F2alpha, with or without exogenous progesterone
Download2004
Schmitt, Eric J. -P., Mattos, Ricardo C., Ambrose, Divakar J., Thatcher, William W., Lopes, Flavia L.
The objectives of this observational study were to document ovarian and endocrine responses associated with the treatment of cystic ovarian follicles (COFs) in dairy cows, using gonadotropin releasing hormone (GnRH) and prostaglandin F2α(PGF) with or without exogenous progesterone. A secondary...

Pathologic Evaluation of Type 2 PorcineReproductive and Respiratory SyndromeVirus Infection at the Maternal-FetalInterface of Late Gestation Pregnant Gilts
Download2016-03-10
Novakovic, Predrag, Harding, John C. S., Al-Dissi, Ahmad, Ladinig, Andrea, Detmer, Susan E.
The pathogenesis of fetal death caused by porcine reproductive and respiratory syndromevirus (PRRSV) remains unclear. The objective of this study was to improve our understand-ing of the pathogenesis by assessing potential relationships between specific histopatho-logical lesions and PRRSV RNA...

Price, M. A., Berg, R. T., Butterfield, R. M., Hardin, R. T., Jones, S. D. M., Fukuhara, R.
Seventy-five young, full-fed, Shorthorn-sired cattle (36 heifers, 24 steers, 15 bulls) were slaughtered over a wide liveweight range (150-550 kg) to evaluate the influence of sex on the patterns of fat deposition.

Patterns of Genomic Variation and Whole Genome Association Studies of Economically Important Traits in Cattle
DownloadFall 2012
Functionally important genetic variations in cattle have great potential as tools to increase agricultural production once they are identified through association studies of phenotype and genotype. The objectives of this thesis were: 1) to characterize the genome-wide patterns of linkage...

Performance and Methane Emissions of RFI Selected Cattle in Drylot and Under Open Range Conditions
DownloadSpring 2018
Residual feed intake (RFI) is a moderately heritable trait that can be used to measure feed efficiency in beef cattle, and thereby reduce feed related costs. RFI has been primarily evaluated under drylot conditions where diet, feed intake and activity levels are controlled and foraging behaviour...
