The ABSC GSC Presents The CREATIVE EXPRESSION of Research Competition

Animal Biosciences Graduate Students-Are you READY for our second CREATIVE EXPRESSION OF RESEARCH competition!? Animal Biosciences Grad Students we want YOU to submit your research with a CREATIVE TWIST  which could take the form of a picture, a song, a twitter or blog post, an infographic, or WHATEVER creative way YOU can think up!! Submissions are made individually, and ALL Grad Students are WELCOME and ENCOURAGED to participate.

The objective of this study was to determine effects of Arg supply on the expression of a se-lect set of genes related to AA metabolism, vascular function, cellular regulation of protein synthesis, and cell differentiation and turnover between the mammary and longissimus dorsi tissues. Six rumen-cannulated, lactating Holstein cows were used in a replicated 3 × 3 Latin square design with 14-d periods. Treatments were continuous abomasal infusion that supplied 0 (ARGx0), 49.2 (ARGx1), and 98.4 (ARGx2) g/d Arg in an otherwise complete AA mixture at 1054 g/d.

The Canadian dairy goat sector has rapidly expanded in the last decade to meet increasing market demand for goat milk products. However, the productivity of Canadian dairy goats varies and increasing production efficiency is critical to the competitiveness of both individual farming operations and the sector. Genetic selection is one proven method of increasing the production efficiency of livestock populations that has been underutilized in the Canadian dairy goat sector.

Sudhanshu Sudan's PhD Defence

Post-weaning diarrhea (PWD) and associated mortality in commercial swine production remain a significant challenge for antibiotic-free meat production. With the ban on antibiotic usage in livestock production, probiotics have gained a lot of attention as a potential alternative. However, strain and host specificity limit their efficacy. In this research, I tested probiotic potential of a novel Bacillus subtilis, BS9 and its impact on growth performance and gut health of weaning piglets.

            Three studies were conducted. In the first study, the influence of a simulated digest of a dietary supplement on the contractile response of gastric smooth muscle to acetylcholine (Ach) was evaluated. Porcine gastric smooth muscle was collected and established in organ baths with either a simulated digest of the supplement (FA), a blank digest with no supplement (BL), or a PBS control (CO). Increasing concentrations of Ach were added and contractile force measured using an isometric force transducer.

CNM Seminar - 360 Degree KTT

Welcome to this month's installment of the 2022 ‘Virtual’ Nutrition Seminar Series hosted by the Centre for Nutrition Modelling of the Animal Biosciences Department. Each month in 2022 we will continue to deliver seminars from a different lab within the Nutrition group, and share their exciting new research in a dynamic virtual manner.
