Milk spectral signature of transition success or failure

A successful transition to lactation is of high importance in dairy production as this period affects the entire productive life of a dairy cow. Poor transition are often associated with clinical or subclinical diseases. The objective is to assess whether milk components are associated with a poor or good cow transition. Emphasis is put on milk components other than the ones routinely measured in monthly milk samples. The spectral signatures of milk from cows analyzed through infrared spectroscopy are therefore assembled.

Impact of garlic supplementation and Residual Feed Intake profile on the occurrence of liver abscesses in feedlots

Feed efficient finishing cattle with none or less severe cases of liver abscesses (LA) will improve the competitiveness and sustainability of the beef industry. The antimicrobial properties of garlic have not been evaluated towards mitigating the severity of LA. Studies evaluating the association between feed efficiency and LA and the integration of emerging feeding strategies such as garlic supplementation are sparse. This project will evaluate the relationship between garlic supplementation strategies and residual feed intake (RFI) profiles on the severity of LA in finishing cattle.

Impact of early life nutrition on nutrient utilization, physiology, and health status of piglets

An improved knowledge of the interaction between birth weight and early-life nutrition is necessary to improve growth performance and health status of piglets. Studies will be conducted that examine the physiological differences between low and normal birth weight piglets, the impact of early-life nutrition on nutrient use and growth performance, and the impact of nursery diet on health status and ability to resist disease challenge.

Investigations on amino acids for optimal gut health and productivity in broiler chickens raised without antimicrobial growth promoters

The largest cost of raising chickens is feed, therefore maintaining chickens in an environment that supports proper nutrition is essential for productivity and profitability. However, nutrient absorption and gut adaptation to luminal inflammatory stress is challenging production efficiency as a consequence of the restriction on the use of antibiotic growth promoters (AGP) and anti-coccidial drugs.

Surveillance and improved control of American foulbrood (AFB) in honey bees in Saskatchewan

The pollination performed by honey bees is estimated to add around $4 billion per year in Canada’s agriculture. Unfortunately, high colony death rates have been repeatedly reported by beekeepers. Infectious diseases (e.g. Varroa, Nosema and American foulbrood [AFB]) are one of the main causes of honey bee mortality.

Production of in vitro and in vivo bison embryos derived from sexed semen

In mammals, the sperm determines the sex of the resulting offspring. Semen sexing is a process whereby sperm are sorted into Y- (male) or X-chromosome (female) bearing gametes. Sexed semen may be used for artificial insemination or in vitro embryo production to create offspring of a desired sex. In a zoo setting, fewer males are required because of their ability to breed multiple females.

How does starch content in starter impact calf gastrointestinal health and development during weaning?

There are gaps in our knowledge concerning calf nutrition when producers feed high amounts of milk to calves along with starter feeds differing in nutrient composition. Mainly, how these calf diets alter lower gut development and health during the pre- and post-weaning periods. This research will utilize pre-weaning calves to assess the effects of diets differing in milk replacer nutrition as well as starch/fiber content in starter on gastrointestinal function and structure as well as overall calf growth.

Improving Growth and Intestinal Health of Broiler Chickens Through the Use of Phytogenic Compounds

The increasing concerns of Canadian government and chicken producers and consumers about antibiotic resistance and its threat to health security has led to a significant reduction in the use of antibiotics in poultry farms. This has led to an increase in intestinal health problems, high mortality, and poor growth of farm-raised chickens, causing significant economic losses for poultry farmers.

The potential for ground mustard seed to improve the environment in the farrowing room for sows and piglets

Mustard is grown throughout Western Canada, primarily for use as a condiment. However, mustard growers are seeking other uses for this crop. Of interest is the potential of ground mustard as an anti-microbial. Mustard contains a compound called glucosinolate, which under the right conditions can be converted to isothiocyanate, a proven anti-microbial. This study will determine if rubbing a small amount of ground mustard on the skin of baby piglets, or placed in the sows’ environment, will reduce the environmental pathogen load those piglets are exposed to.

EcoSix : L’élevage d’insectes comestibles en économie circulaire urbaine pour lutter contre le gaspillage alimentaire et les changements climatiques

Les insectes comestibles représentent une alternative durable à la viande conventionnelle. La diète omnivore des ténébrions meuniers peut permettre une saine gestion des résidus alimentaires et ses déjections ont des propriétés fertilisantes. De fortes barrières psychologiques et économiques freinent la progression de la consommation d’insectes au Canada. L’objectif du projet EcoSix est de développer un procédé optimal pour l’élevage et la mise en marché de ténébrions en misant sur l’économie circulaire de proximité.
