Upcoming Events

Greetings Animal Biosciences,    Can you believe that 2021 is almost finished? The Graduate Student Council (ABSc GSC) is BACK with the last student run EVENT of the year! A department wide SNOWMAN BUILDING COMPETITION!

Nanostring nCounter technology enables multiplexed quantification of up to 800 RNA, DNA or protein targets from a variety of samples sources. This virtual seminar will provide an overview of the technology including capabilities and range of applications. Check your email and calendar for the Zoom meeting link. Hope to see you there!

Animal robustness is essential in the poultry industry because of its consequences for animal health, wellbeing, and industry profitability. Strategies to improve animal robustness can include quantifying environmental sensitivity or direct selection for ro-bustness-related traits, however, these have come with limited success.

MicroRNAs interfere with translation of mRNAs through complementary binding at the 3’ untranslat-ed region (UTR). MicroRNA-29b-3p (miR-29b) is localized to the nucleus in porcine granulosa cells, but its function is unknown. We hypothesized miR-29b binds to nuclear DNA to regulate transcrip-tion. We analyzed genes regulated by miR-29b for potential binding sites in their promoter regions. MiR-29b may bind to the promoter regions of GLUL, CDKN2B, and NR2F2, but does not regulate NR2F2 transcription. We instead identified genes miR-29b may regulate via 3’ UTR repression.

Please join us for the DECEMBER 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 December we bring you:

We are very pleased to have Murilo Carvalho, an Education and Extension Specialist at Holstein Canada, to present a CGIL Seminar on Friday December 10th 2021. The seminar will begin at 1:30 PM EDT/EST on the virtual platform Microsoft Teams. The title of the presentation is: “Breeding the cows of the future – where genetics, phenotype, and management must get together”.

Bones are a highly complex tissue capable of adapting to changes in muscle usage through specialized cells which respond to mus-cle strain. As such, the way in which birds utilize their wings has a direct impact on strain production of the flight muscles, and sub-sequently the keel bone to which the muscles anchor. Currently, adaptations of muscle and bone in response to a decrease in wing use is unknown in laying hens. Therefore, the first study (Chapter 2) sought to investigate if a loss of flight feathers (reduction to wing area) would reduce wing activity.

Free-stalls are an important area of dairy production where cow comfort should be maximized. Comfortable free-stalls con-tribute to the cows’ ability to achieve adequate rest, which translates into improved health and production. However, free-stalls are generally designed to promote cleanliness and reduce the labour required for maintenance through restricting cow behaviour. The overall objective of this thesis was to evaluate a novel free-stall designed to improve cow comfort using an increased stall slope, minimal stall partitioning, a heat abatement system, and supplemental lighting.
