Characterization and evaluation of residual feed intake measured in mid- to late-gestation mature beef cows and relationships with circulating serum metabolites and linear body measurements
Download2014
Miller, S. P., Swanson, K. C., Wood, K. M., Montanholi, Y. R., Fitzsimmons, C. F, McBride, B. W.
To evaluate the use of residual feed intake (RFI) models measured in mid-to-late gestating beef cows, a dataset was used combining data from five experiments containing nine treatment and/or replicate groups for a total of 321 animal records. Investigations of RFI models included the effects of...

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...

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 acidosis is a persisting digestive disorder in modern ruminant production; however, the susceptibility of cows to ruminal acidosis differs among cows fed a common diet. The overall objective of this research was to evaluate factors affecting the susceptibility of cows to ruminal acidosis....

USING IN-LINE MILK PROGESTERONE DATA TO DETERMINE OVARIAN ACTIVITY PARAMETERS ASSOCIATED WITH REDUCED FERTILITY IN CANADIAN HOLSTEIN COWS
DownloadFall 2017
Improvements in genetic selection and dairy management practices have resulted in dramatic increases in individual milk production over past decades. However, this positive trend has been accompanied by decreased reproductive performance and fertility in dairy cows. Infertility in modern dairy...
