Improving Accuracy of Genomic Prediction for Economically Important Traits in Canadian Holstein Dairy Cattle
DownloadSpring 2017
Milk is a valuable source of energy, high quality protein, and several key minerals and vitamins for humans. Selection for milk production in dairy cattle was first based on phenotype and pedigree information and the knowledge of genetic parameters for the trait of interest. However, substantial...

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...

The calving transition is a challenging period for dairy cows characterized by negative energy balance, metabolic dysfunction, and inflammation, each of which may compromise milk production. Despite extensive research in this area, much is still unknown on how to best manage this period. The...

Prediction of residual feed intake for first lactation dairy cows using orthogonal polynomial random regression
Download2013
Okine, E. K., Goonewardene, L. A., McFadden, T., Basarab, J. A., Wang, Z., Manafiazar, G., Li, P.
Residual Feed Intake (RFI) is a measure of energy efficiency. Developing an appropriate model to predict expected energy intake while accounting for multifunctional energy requirements of metabolic body weight (MBW), empty body weight (EBW), milk production energy requirements (MPER), and their...

Ruminal methanogenesis is a microbial fermentive process conducted by methanogens, releasing methane (CH4) gas through eruction, and resulting in a dietary energy loss to the host animals and a contribution to greenhouse gas emissions by the agricultural industry. However, the association amongst...

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,...

Squires, J. J., Moore, S., Stothard, P., Swanson, K. C., Miller, S. P., Abo-Ismail, M. K., Vander Voort, G., Liao, X., Plastow, G., Mandell, I. B.
Background This study was conducted to: (1) identify new SNPs for residual feed intake (RFI) and performance traits within candidate genes identified in a genome wide association study (GWAS); (2) estimate the proportion of variation in RFI explained by the detected SNPs; (3) estimate the...
