Crossbreeding is an effective method for improving the efficiency of production in commercial cow-calf operations. It exploits available heterosis (hybrid vigour) and complementarity between different breeds or populations (lines). Before adopting a crossbreeding system, commercial cattle...

Dlusskaya, Kira Konstantinovna
Raising animals has been an important aspect of human food systems for millennia, but with growing climate concerns, the management of animal agriculture, including beef production, needs to adhere to environmental best practices. Determining what these practices are has been the subject of much...

Methane (CH4) is a greenhouse gas with an elevated global warming potential (GWP) equivalent to 28 times that of CO2. Also, production of enteric CH4 results in a 2 to 12% loss of the gross energy intake of cattle thus knowing the amount of CH4 released to the environment is important. The...

In ruminants, evidence is accumulating regarding the associations between rumen microbial taxonomic features and feed efficiency. However, to date, how rumen microbial functional features contribute to the variations in feed efficiency of beef cattle has not been well understood. Moreover,...

Fifty-three cross-bred bulls, aged 5–7 mo, were divided at random into a nonimplanted control group of 26 bulls and a treatment group of 27 bulls, which were each implanted with 36 mg of zeranol on the 1st, 81st, and 155th day of the experiment. They were fed a high energy diet ad libitum for 168...

The Political Economy of Animal Testing and Traceability in Response to Transmissible Spongiform Encephalopathies (TSEs)
DownloadSpring 2015
Transmissible Spongifrom Encephalopathies (TSEs), which include bovine spongiform encephalopathy (BSE) in cattle and chronic wasting disease (CWD) in cervids, are associated with three possible risks. The risks of food safety outbreaks, the risks to economic benefits, and the risks to society's...

The use of modern metabolomics and proteomics to address the health challenges facing the Canadian cattle industry
DownloadFall 2013
Naturally cattle only consumed grass, hay and other forage crops but modern cattle industry has started shifting them from a natural grazing diet to a more balanced grain-rich diet. However, feeding dairy cows grain rich diet is associated with a rapid release of large amounts of SCFA that have...

This thesis examines consumer behavior towards food risks in three different papers, focusing on two food concerns: genetically modified (GM) food and bovine spongiform encephalopathy (BSE). The first paper investigates the roles of different measures of trust on consumers’ stated choices for...

Variations in and relationships between reproductive performance and growth parameters in yearling beef bulls in single sire mating at pasture
Download1989
Makarechian, M., Farid, A., Berg, R. T., Price, M. A.
Yearling bull fertility, measured as pregnancy rate, percentage of calves born during the first 4 and 6 wk of calving and mean and median of calving date distribution, were studied in 109 single-sire breeding herds of two breed groups over a 10-yr period. The breed groups were Herefords bulls...
