Maternal and Paternal Genomes Differentially Affect Myofibre Characteristics and Muscle Weights of Bovine Fetuses at MidgestationDownload
Postnatal myofibre characteristics and muscle mass are largely determined during fetal development and may be significantly affected by epigenetic parent-of-origin effects. However, data on such effects in prenatal muscle development that could help understand unexplained variation in postnatal...
Modification of steer muscle composition and meat quality through age at slaughter, hormonal implants, ractopamine hydrochloride feed supplementation, and breed crossesDownload
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 digestibilityDownload
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,...
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 progesteroneDownload
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...
Patterns of Genomic Variation and Whole Genome Association Studies of Economically Important Traits in CattleDownload
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...
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.
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...
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....
