The Animal Nutrition Association of Canada (ANAC) is pleased to offer the ANAC Graduate Scholarship. Eligible students (Canadian citizens and permanent residents of Canada) must be enrolled in a Canadian university graduate program in Animal Science or related field of study and have a specific interest (research project/course selection) in animal nutrition.
The ANAC Graduate Scholarship is made possible through funding by ANAC member companies. The intent of this annual national scholarship is to encourage students to consider pursuing a career in the feed industry.
In addition to the $4,000 award, the scholarship recipient will have the opportunity to present their research at the opening plenary of the Animal Nutrition Conference of Canada (ANCC). The ANCC is a dynamic conference that brings together researchers and feed industry specialists to exchange knowledge about the latest scientific developments related to livestock nutrition.
2022 ANCC Scholarship Recipient
This year’s ANAC scholarship winner is Amanda J. Fischer-Tlustos, PhD student at the University of Guelph.
Amanda will be presenting her recent research at the Animal Nutrition Conference of Canada. Read her abstract below:
The Influence of Transition Diet Energy and Protein Content on Colostrum and Early Lactation Milk Composition and Bioactive Compound Concentrations in Holstein Dairy Cattle
Colostrum and transition milk (TM) contain elevated levels of energy substrates and bioactive factors that are crucial to calf development; however, dam factors that control their concentrations are not well understood. The objective of this study was to evaluate how prepartum dietary energy density affects colostrum composition and how pre- and postpartum dietary energy and protein content, respectively, affect TM and mature milk composition. Multiparous (MP; n = 28) and primiparous (PP; n = 20) Holstein cows were randomly assigned within block to a close-up diet (CUD) containing low (LED; 1.10 Mcal NEL/kg DM) or high (HED; 1.52 Mcal NEL/kg DM) levels of energy from 19 ± 4.0 d prior to expected calving date, and to a high protein (HPD; 18.5% crude protein (CP), 1.73 Mcal NEL/kg DM) or average protein (APD; 15.5% CP, 1.68 Mcal NEL/kg DM) postpartum diet (PPD) after calving. Fat, CP, lactose, milk urea nitrogen (MUN) and total solids (TS) concentrations were determined by infrared spectroscopy, and IgG was quantified by radial immunodiffusion in colostrum (milking 1), TM (milkings 2 to 7) and mature milk (16 ± 1.9 d postpartum). Data were analyzed using a linear mixed model considering the fixed effects of parity, milking, CUD, PPD and their interactions, and the random effects of cow and block. The CUD had a greater effect on MP cows than PP cows; HED MP cows had greater (P < 0.0001) DMI from wk -3 relative to calving and increases in yields of milk (24.8%; P = 0.02), fat (37.7%; P = 0.007), CP (14.0%; P = 0.04), and TS (35.3%; P = 0.02) throughout the entire sampling period compared to LED MP cows. There were no differences between CUD within specific milkings. In contrast to the CUD, the PPD did not differentially affect MP and PP cows. On average, APD cows tended (P = 0.06) to have 200 g greater TS yield and had 85.4 g greater (P = 0.04) CP yield and 3.4 mg/dL lower (P = 0.04) MUN than HPD cows. No differences were observed for IgG concentrations; however, LED-APD cows produced an additional 31.2 g (P = 0.02) of IgG compared to LED-HPD cows over the sampling period. The results suggest that increasing close-up diet energy density may be a strategy to improve component yields, with the exception of IgG, in multiparous cows in early lactation.
