Tianna Sullivan's MSc Defence

Genetic selection of dairy cattle for improved stressed resiliency is one strategy for mitigating the harmful effects of stressors that are expected to intensify as a result of climate change. With global temperatures increasing 0.15-0.20 °C since 1975, there has been a reduction in the quantity and quality of feedstuffs and drinking water, promoting the survival and distribution of pathogens and their vectors.

The use of pulses as a protein supplying ingredients in animal feed, including swine, are limited. Pulses are often limited in one or more amino acids (usually methionine/cysteine and/or tryptophan), resulting in reduced protein quality of the ingredient compared to animal derived protein sources. A deeper understanding on the effects of processing on pulse nutrients and on protein quality, and developing both standardized ileal digestibility (SID) coefficients as well as metabolic availability (MA) of amino acids of pulses will allow for greater utilization.

Munene Kithama's PhD Defence

Fruit pomaces are rich in functional phytochemicals that could be beneficial in antibiotic free and organic poultry production. This work investigated nutritional and functional effects of pomaces in broiler chickens without or with feed enzymes (ENZ). The first study investigated the apparent metabolizable energy (AME) of apple (APL), grape (GRP), cranberry (CRP) and low-bush wild blueberry (LBP) pomaces. Results revealed that the highest AME was observed with APL and that ENZ had no effect on AME.

Title: Effects of space allowance on behaviour, physiology, skin lesions and meat quality of pigs transported in an actively ventilated vehicle in the summer and winter.

Bruna Mion's PhD Defence

The objectives of this thesis were: 1) to investigate the impact of complete replacement of inorganic salts of trace minerals (Co, Cu, Mn, and Zn sulphates and Na selenite) by organic trace minerals (Co, Cu, Mn, and Zn proteinates and selenized yeast) in both pre- and postpartum diets of dairy cows on the measurements of rumen fermentation, feeding behavior, performance, trace mineral concentration, antioxidant biomarkers, health status, ovarian and uterine biology, conceptus development and reproductive performance, and 2) to evaluate the contribution of systemic inflammation to short- and

CNM SEMINAR: How to Make Androids Dream of Electric Cows

Welcome to the September Installment of the 2022 Nutrition Seminar Series, hosted by the Centre for Nutrition Modelling (Animal Biosciences Department). Each month in 2022 we will continue to deliver seminars from a different lab within the ABSC Nutrition group, and share their exciting new research in a dynamic manner. 

CGIL Seminar - "Implementation of Two Trait Analysis for Heat Stress In Swine"

Good afternoon CGIL, Unfortunately, Dr. Albert De Vries will not be able to present this Friday due to the imminent storm in the US. We updated our seminar and Gabriella Dodd will give a presentation this Friday September 30th, 2022. The seminar will begin at 1:30 PM EDT/EST on the virtual platform Microsoft Teams. The title of the presentation is: "Implementation of Two Trait Analysis for Heat Stress In Swine".
