This project researched the effects of pullet-phase feed restriction methodology or management and hen-phase diet fortification on female broiler breeder BW and carcass trait uniformity as well as on performance of the broiler offspring. Feed treatments had a significant effect on female BW and...
This study aimed to examine potential mechanisms for glucocorticoid (GC)-induced decreases in glucose clearance, and to determine if a reduction in oxidative stress load via dietary pre-treatment with an antioxidant-rich diet has a positive net effect on glucose tolerance following a sub-chronic...
Evaluation of a pedometer system for prediction of estrus and parturition in dairy cows housed in a tie-stall barnDownload
Physiological changes associated with estrus and parturition in dairy cows are manifested by changes in activity and behaviour. Accurate and timely detection of cows in estrus and those approaching parturition is very important. The research objective was to determine the efficiency of the...
Evaluation of dried distillers grains with solubles as a partial replacement of barley silage or barley grain in diets for lactating dairy cowsDownload
Feeding value of dried distillers grains with soluble (DDGS) as an energy source for lactating dairy cows was evaluated in two studies. A diet in which barley grain was replaced by DDGS at 20% of dietary dry matter (DM) did not affect milk yield but tended to increase rumen pH compared with the...
Evaluation of the threonine requirement and the bioavailability of threonine in feedstuffs in pregnant sowsDownload
Current recommendations for amino acid intake during pregnancy are for a constant amino acid intake throughout. However, the demand for amino acids changes from maternal tissue growth in early gestation to fetal, conceptus and mammary tissue development in late gestation. The availability of...
Triticale (×Triticosecale Wittmackk) is being actively explored as a feedstock for bioethanol production in Canada. As the main co-product of bioethanol processing, triticale distillers grain contains 20-43% protein (dry basis), and mainly used as animal feed. The purpose of this study was to...
Factors contributing to the competitiveness of Lactobacillus reuteri in sourdough and rodent gutDownload
Lactobacillus reuteri is a common organism in cereal-based foods and a gut symbiont in humans and animals, yet the molecular mechanisms allowing its persistence in various niches are not well understood. L. reuteri LTH2584 produces reutericyclin and persists in industrial sourdoughs, where acidic...
Feeding value of triticale-based dry distillers’ grains plus solubles in the diets of growing lambsDownload
Nutrient profiles of distillers’ grains are primarily affected by the type of grain used for ethanol production, but the feeding value of triticale-based dry distillers’ grains plus solubles (TDDGS) has not been extensively studied. The first study showed that, compared to 20% corn- or...
Fine scale mapping and association study of economically important traits on chromosomes 19 and 29 in beef and dairy cattleDownload
The objective of this thesis was to construct radiation hybrid (RH) maps and estimate linkage disequilibrium (LD) using high density SNP markers on chromosomes 19 (BTA19) and 29 (BTA29) and use these as a tool to detect QTL in dairy and beef cattle. We have constructed RH maps of BTA19 and BTA29...
