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...

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...

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...

One hundred-and-twelve yearling bulls were penned together for at least 3 mo in groups of 7 or 21. They were then shipped 150 km to an abattoir in groups of either 7 or 21, and were either regrouped or not regrouped before shipment. They were held overnight at the abattoir before slaughter. A...

Proteome differences associated with fat accumulation in bovine subcutaneous adipose tissues
Download2010
Basu, U., Guan, L., Dodson, M. V., Zhao, Y. M., Basarab, J. A.
Background The fat components of red meat products have been of interest to researchers due to the health aspects of excess fat consumption by humans. We hypothesized that differences in protein expression have an impact on adipose tissue formation during beef cattle development and growth....

Reducing GHG emissions through genetic improvement for feed efficiency: Effects on economically important traits and enteric methane production
Download2013
Baron, Vern S., Ominski, Kim H., Guan, Leluo, Basarab, John A., Beauchemin, Karen A., Miller, Stephen P.
Genetic selection for residual feed intake (RFI) is an indirect approach for reducing enteric methane (CH4) emissions in beef and dairy cattle. RFI is moderately heritable (0.26 to 0.43), moderately repeatable across diets (0.33 to 0.67) and independent of body size and production, and when...

Rumen microbial community composition varies with diet and host, but a core microbiome is found across a wide geographical range
Download2015
Cox, Faith, Janssen, Peter H., Henderson, Gemma, Jonker, Arjan, Young, Wayne, Ganesh, Siva
Ruminant livestock are important sources of human food and global greenhouse gas emissions. Feed degradation and methane formation by ruminants rely on metabolic interactions between rumen microbes and affect ruminant productivity. Rumen and camelid foregut microbial community composition was...

Plastow, G., Stothard, P., Moore, S., Bao, H., Meng, Y., Liao, X.
Gene duplication is a widespread phenomenon in genome evolution, and it has been proposed to serve as an engine of evolutionary innovation. In the present study, we performed the first comprehensive analysis of duplicate genes in the bovine genome. A total of 3131 putative duplicated gene pairs...
