Get ready for the APRIL Installment of the 2021 ‘Virtual’ Nutrition Seminar Series, hosted by the Centre for Nutrition Modelling (Animal Biosciences Department). Each month in 2021 a different lab within the Nutrition group will share their exciting new research in a dynamic virtual manner.  In April we bring you: Tentative title: Integrating breeder and early life nutrition for enhanced poultry production  

Reasons that wildlife are brought to wildlife rehabilitation centres across Canada has not been documented from coast to coast. However, it is well-known that humans have a direct or indirect impact on wildlife. But just how pervasive are human impacts on wildlife across Canada? How have hunting and fishing activities affected wild birds in Ontario, specifically Trumpeter Swans (Cygnus buccinator)? And how can we diagnose some health issues in wild birds, specifically lead toxicity, given constraints of laboratory testing parameters?

The departmental meeting is open to all staff, post-doctoral fellows, research assistants/associates/technicians, students and visitors. Please join us to catch up on everything going on in ABSc!

This thesis investigates the effects of neomycin inclusion in milk replacer on health and performance, as well as gut health and function in preweaned male Holstein calves. When investigating the effects of neomycin on health and performance, it was found that neomycin reduced the severity and length of diarrhea experienced by calves, as well as the number of days with diarrhea. However, few benefits were observed in other indications of health, including growth, feed efficiency, and respiratory illness.

House soiling in domestic cats has resulted in many cats being surrendered to an animal shelter or euthanized. The objective of this thesis was to determine how effectively cats transitioned from one litter product to another, as well as to determine the efficacy of using an attractant compound built directly into a litter product to attract cats to the litter box.

The objective of this thesis was to investigate the impact of dietary selenium (Se) source on absorption, retention, per-formance, Se status, and immune function. Twenty-four mid-lactation Holstein cows were randomly assigned to receive 0.3 mg/kg DM of either an inorganic or organic Se premix. Following an 11-week dietary adaptation period, cows received simultane-ous intra-ruminal (Se77) and intravenous (Se82) isotope infusions followed by a 4-day total collection. On week 13, a subset of cows (n=20) received an intramammary infusion of 50 μg of lipopolysaccharides (LPS).

Recently, the consumption of grain-free diets has been linked to the development of canine dilated cardiomyopathy, with or without taurine deficiency. The focus of this thesis is on the micronutrients involved in taurine synthesis in healthy dogs fed a grain-free diet and defining the grain-free consumer via survey. Dogs supplemented with methionine had increased plasma methionine and homocysteine concentrations post-meal.
