3MT (R) Competition

Every year, the University of Saskatchewan holds their annual Three Minute Thesis (3MT (R)) competition. Graduate students have 3 minutes and 1 presentation slide to present their research. This year, Hemlata Gautam one third place with her presentation "Protecting Chickens from a Gut Rotting Bacteria".

Watch Hemlata's 3MT!

Images of Research Competition

The University of Saskatchewan held it's 9th annual Images of Research Competition. This year, there were 143 entries in 5 categories, from students, faculty, staff and alumi.

Mihiprabha Rathnayake won the Viewer's Choice award, with her image titled "Happy Birth Little Chicky - You are GIFT-ED!".

Candling is a method used to observe the growth and development of an embryo inside an egg which uses a bright light source behind the egg to show details through the shell. Fully developed chick will come out from the eggshell on day twenty-one. This photo was taken while candling just before hatch, and the little chick was trying to break the shell using its beak.  My research is on delivering probiotics into chicken embryos by spraying probiotics on the eggshell to protect neonatal chicks from infectious diseases like Salmonella. This 20 days old chicken embryo was already GIFT-ED with good bacteria (probiotics) so that it is ready to fight against infections. There’s no doubt that it’s a HAPPY BIRTH!!!!

Researchers aim to develop vaccine for infectious poultry disease

"Infectious bursal disease virus (IBDV) in broiler chickens (birds raised for meat) is a costly issue not only in Canada but worldwide. While Saskatchewan represents less than four per cent of Canada’s total poultry industry, the province loses an estimated 3.9 million kilograms of meat per year in Saskatchewan because of this virus."

Researchers success in replicating poultry disease key to prevention

Necrotic enteritis, an intestinal disease caused by the bacteria Clostridium perfringens, primarily affects broiler chickens (poultry raised for meat) at a young age when their immune systems are immature. The disease causes the death of their intestinal lining and severely compromises their health.

One of the most common infectious diseases of poultry, necrotic enteritis has a significant economic impact on the poultry industry.

“Every year necrotic enteritis costs the global poultry industry $5 billion to $6 billion because of reductions in performance and the cost of disease treatment,” says Hemlata Gautam, a PhD student in the WCVM’s Department of Veterinary Pathology.

BioOne Ambassador Award

Kalhari Bandara Goonewardene received the award which recognizes early-career researchers who excel at communicating the importance and impact of their research beyond their discipline.

Goonewardene’s research focuses on raising healthy chickens, something vital to human health.

“Baby chicks on poultry farms often get sick from bacterial infections during the first week of hatching, resulting in the death of many chicks and severe economic losses for producers,” said Goonewardene.

Goonewardene said the poultry industry previously used antibiotics to prevent infections but these practices raised public health concerns including the emergence of antibiotic-resistant bacteria. In response, the poultry industry is responsibly withdrawing from antibiotic use to ensure public health and safety, and actively searching for safe and effective alternatives to ensure poultry health.
