Intersections of animal production practices on meat quality, intramuscular collagen and expression of genes related to collagen and myofibrillar synthesis and degradation
DownloadSpring 2022
Beef quality, particularly tenderness, continues to be a major challenge in the beef industry resulting in significant economic losses. Beef tenderness is influenced by genetic factors, especially the expression of genes associated with collagen and collagen crosslink synthesis, live production...

Application of Multi-Omics Tools to Study the Genetic Background of Economically Relevant Traits in Commercial Beef Production
DownloadSpring 2022
The sustainability and profitability of beef cattle production are largely associated with feed efficiency, carcass merit, and resistance to infectious diseases. These traits are difficult or expensive to measure on individual animals, which makes them suitable for genomic application. Currently...

Livestock metabolomics is an emerging field of metabolomics that is growing at a fast rate. The ability to rapidly detect and quantify hundreds or even thousands of metabolites within a single sample is helping livestock scientists paint a far more complete picture of animal metabolism and...

Hashemiranjbar Sharifabad, Mohsen
Feed represents more than half of the costs of livestock production. Residual feed intake (RFI) is a phenotypic measure of feed efficiency that has been proposed as the best approach for genetic improvement of dairy cows. Although RFI is considered as a useful tool for feed efficiency, the...

Approximately 70% of the cost of beef production is impacted by dietary intake. Maximizing production efficiency of beef cattle requires not only genetic selection to maximize feed efficiency (i.e. residual feed intake - RFI), but also adequate nutrition throughout all stages of growth and...

Assessment of rumen microbiota in beef heifers with different feed efficiency and managed under different feeding systems
DownloadSpring 2020
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...

Identification of functional genes for feed efficiency traits via transcriptome analyses to enhance the genomic prediction accuracy in beef cattle
DownloadFall 2019
Residual feed intake (RFI), a measure of feed efficiency, and its component traits including average daily gain (ADG), dry matter intake (DMI) and metabolic weight (MWT) are traits of great economic importance to the beef industry. The genetic improvement of these traits can improve the...

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...

Effects of Selection for Low Residual Feed Intake on Meat Quality of Major Muscles from Angus, Charolais and Kinsella Composite Cattle
DownloadFall 2017
Residual feed intake (RFI) is a measure of animal feeding efficiency. Selection of high feed efficient cattle using RFI does not affect production performance; low RFI animals consume less feed to reach a similar body weight gain as high RFI animals and thus are considered as feed efficient...

Fall 2017
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,...
