Abstract A procedure to secure a jugular vein catheter system to the neck of cattle is described. A wide-mouthed polypropylene bottle attached to a halter strap provided a secure container for the catheter. This device allowed convenient access to the catheter for repeated sampling and,...

A technique is described for meausuring increases in bone length during defined periods before slaughter in cattle. It consists of jugular infusions of oxytetracycline at specified time intervals. Oxytetracycline identifies the sites of ossification in growing bones at the time of infusion by...

A trial is reported comparing the accumulation of lipid in rib cuts from 12 bull and 12 heifer carcasses from two breed types: Hereford (HE) and Dairy Synthetic (DY). Serial slaughter was carried out from weaning (163 ± 15.1 (SD) days) to approximately 16 mo of age. The left side of each carcass...

Background MicroRNAs (miRNAs) are a class of molecular regulators found to participate in numerous biological processes, including adipogenesis in mammals. This study aimed to evaluate the differences of miRNA expression between bovine subcutaneous (backfat) and visceral fat depots (perirenal...

We developed a marker based infinitesimal model for quantitative trait analysis. In contrast to the classical infinitesimal model, we now have new information about the segregation of every individual locus of the entire genome. Under this new model, we propose that the genetic effect of an...

Improving feed efficiency has become a top priority in beef cattle production because of the rapidly increasing cost of feed provision. However, because of the expense associated with collecting individual animal feed intake data, only a relatively small number of animals have been tested,...

Genetic improvements in beef and dairy cattle can bring significant advances in satisfying the global food demand, which is expected to double by 2050. Several DNA markers have been identified on bovine chromosome 14 (BTA14), but low mapping resolution prevents their refinement for identification...

Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

The linkage between rumen microbiota and feed efficiency has been studied in cattle managed under the drylot system, especially in the feedlot with high-grain diets. However, pasture-based beef operations still dominate the beef production system around the world. In Alberta and other provinces...

Data on 99 young bulls, which were the progeny of matings of either double muscle bulls and normal cows (DMx) or normal bulls and normal cows (N) born over three calving seasons, were analyzed to compare the carcass characteristics and lean yield of yearling DMx and N bulls. DMx carcasses had...
