The objective of this study was to use the candidate gene approach to identify the genes associated with carcass quality traits in beef cattle steers at the University of Alberta Ranch at Kinsella, Canada. This approach involved identifying positional candidate genes and prioritizing them...
The relationships between meat tenderness and the changes in metabolism and body composition associated with compensatory growth in cattle were examined. Thirty-six steers were randomly allotted to 12 pens of three with three diets assigned randomly to the pens. Diets were alfalfa/grass silage,...
Meat tenderness may be improved by accelerating muscle metabolism or by damaging muscle structure and increasing the solubility of muscle proteins. Pre- and postrigor protein and collagen solubilities were measured in semitendinosus muscles, removed pre-rigor from 24 Charolais crossbred steer...
Enzyme addition facilitates the post-disease compensatory growth of broiler chickens challenged with Clostridium perfringensDownload
In vitro incubation studies using a multicarbohydrase supplement showed a significant depolymerization of nonstarch polysaccharides (NSP) of soybean meal (SBM), canola meal and flaxseed meal, which was associated with the production of water-soluble NSP hydrolysis products. Effects of diet type...
Estimation of genetic and phenotypic parameters for ultrasound and carcass merit traits in crossbred beef cattleDownload
Ultrasound measurements of 852 crossbred steers along with carcass merit measurements on 756 of them were used to examine their genetic and phenotypic parameters. Traits including ultrasound backfat thickness (UBF), ultrasound ribeye area (UREA), ultrasound marbling (UMAR), carcass weight (CWT),...
Feeding flaxseed enhances deposition of omega-3 fatty acids in broiler meat portions in different mannerDownload
Feeding a diet containing 12% flaxseed for 36 d significantly increased the n-3 fatty acid deposition in broiler meat. Based on this study, consuming 100 g of such fatty acid-enriched breast meat, whole leg or wing, a total of 0.2, 1.6 and 2.0 g of n-3 fatty acids, including 10.4, 20.3 and 25.3...
Interactive effects of low voltage electrical stimulation and leg restraint on meat quality of Charolais crossbred steer carcassesDownload
The meat quality of the longissimus muscle of 12 Charolais crossbred steers that were electrically stimulated on randomly selected sides approximately 1 h postmortem was investigated. Temperature and pH measurements were taken on each side at 5 min prior and 1, 4, 24 and 48 h subsequent to...
Multilocus sequence typing analysis of Clostridium perfringens isolates from necrotic enteritis outbreaks in broiler chickensDownload
Clostridium perfringens is an important pathogen of animals and humans and is the causative agent of necrotic enteritis (NE) in poultry. This study focuses on the typing of intestinal C. perfringens isolates (n 61) from outbreaks of NE collected from several areas of Southern Ontario, using a...
Necrotic enteritis potential in a model system using Clostridium perfringens isolated from field outbreaksDownload
Necrotic enteritis is an enteric disease of avian species caused by the anaerobic bacterium Clostridium perfringens. The disease is regularly controlled in the broiler chicken industry through the use of antimicrobials in feed, but is re-emerging in areas such as Europe where there is a ban on...
