Direct-fed microbials (DFM) like Lactobacillus acidophilus (LA) can influence the composition of the gastrointestinal tract (GIT) microbiota of ruminants resulting in beneficial effects on health and productivity. In this study, the GIT microbiota of 16 calves (8/treatm...

The objective of the present study was to document current commercial practices during long haul transport (≥400 km) of cattle in Alberta through surveys delivered to truck drivers (6,152 journeys that transported 290,362 animals). The live beef export industry to the U...

Experiments were conducted to investigate the effects of the presence of a trainer cow on behavior, performance, health, and feeding patterns of newly weaned beef calves. In Exp. 1,252 weaned calves (270+/-18 kg) were allocated to 22 pens (11 to 15 calves per pen). A tr...

The objectives of this study were to examine the impact of corn- or wheat-based dried distillers grains with solubles (CDDGS or WDDGS) on enteric methane (CH4) emissions from growing beef cattle and determine if the oil in CDDGS was responsible for any response observed...

The widespread use of antibiotics has lead to the increased presence of pathogens that are less susceptible to their antibacterial effect. Lactoferrin (Lf) is naturally produced by the mammary gland. Lactoferrin is the main whey protein in human milk and is also present...

Two experiments were conducted to determine mechanisms mediating effects of nutritional manipulation before and after mating on embryonic survival in pigs. Experiment 1 studied the mechanisms by which continued high feeding levels after mating result in differences in p...

Two experiments were conducted to quantify the effects of lasalocid on the performance and energy partitioning of cattle fed a 90% concentrate, barley-based diet. Experiment 1 utilized 100 Hereford heifers (initial weight 308 kg) fed diets containing no added ionophore,...
