Recent immigrants and refugees to Canada bring knowledge and skills that strengthen the economies, sociocultural aspects, and food systems of their new communities. However, challenges associated with being a newcomer, including access to culturally preferred foods compounds food insecurity - inadequate or insecure access to food due to financial constraints - experienced by new immigrants.
This project focus on designing a fatigue cycling machine to test soil openers for low cycle, impact fatigue. This process begins by identifying and characterizing the load in case, and then continue into detailed design, fabrication and commissioning. Characteristics such as robustness, reliability and safety will be strongly emphasised. This testing machine will then form a basis for further research on opener design.
It is very important to test the soil openers before releasing them, to assure that the customers that acquire them will not have problem during their seeding period.
Automated harvesting of horticultural produce is an opportunity for Canadian farmers to improve the quality of yield, reduce labour costs, and increase revenues. The research project will focus on the design and development of soft pneumatically-driven robotic grippers that conform to the natural shape of delicate produce, such as mushrooms, in an effort to minimize crop damage during harvesting. The operating principle of the proposed grasping mechanism is based on the concept of a pneumatic artificial muscle.
Enzymes play an essential role in the animal nutrition industry and are used to increase the nutritional value of feedstuff, resulting in improved production cost, feed efficiency, and animal performance. Many manufacturers choose to pelleting feed, for reasons such as increased feed intake and feed efficiency. However, many enzymes become deactivated when exposed to the high temperatures used during the pelleting process, and the feed will no longer provide benefits to the animal. There is a need to identify enzyme products that can withstand temperatures used during the pelleting process.
The role of companion animals has evolved over the years of their domestication from that of purely utilitarian hunting or working partnerships to a relationship now more closely resembling that of a family member. Unsurprisingly, trends in companion animal nutrition have begun to closely shadow trends in human nutrition, reflecting the desire of pet owners to feed their companions diets which they consider healthy and beneficial for their pets wellbeing.
In 2012, the estimated value of forage in Canada was $5.1 Billion. Forages are the foundation for the beef and dairy sectors which have a combined economic activity of $50 Billion. However we have recently seen a loss of nearly 2.2 Million acres of pasture land across Canada, which means productivity from our remaining forage lands must improve for the future competitiveness of the beef industry. This project contains 4 research activities on alternative forages and improved technologies that will increase the productivity and quality of the forage industry in Saskatchewan and Canada.
The human pathogenic bacteria Salmonella enterica and Campylobacter jejuni are commonly found in the intestine of poultry. Consumption of infected chicken and eggs, and its derivatives, is the main and most important source of infection outbreaks in humans causing diarrhoea, fevers and abdominal cramps. In some cases, severe diarrhea and dehydration followed by systemic spreading of these infections is life-threatening. At present, no widely effective strategy is available to control both Salmonella and Campylobacter colonization of broiler chickens to prevent the infection in humans.
The equilibrium moisture content (EMC) is an important physical property that significantly impacts all hygroscopic biomaterial. Knowledge of EMC of grains and pulses including soybeans is essential for efficient post-harvest operations such as drying, aeration, or storage. EMC changes with the variety but is also affected by handling and aeration practices. During storage, seeds undergo many micro-wetting and drying cycles or freezing and thawing cycles, which also affect the sorption and desorption characteristics.
Postharvest rot of sweet cherry destined for export markets has caused significant economic losses to Okanagan growers. The major fungal pathogens causing rot have not been identified. This project will identify the two major pathogens responsible for postharvest rot in cherry during two growth seasons and characterize them with respect to temperature effects on growth and sensitivity to fungicides. Using DNA-based methods we will track the abundance of the pathogens in the orchard during the growth cycle of cherry, following major rain events and postharvest.
In western Canada, increased nutrient demand associated with decreased temperatures and increased fetal growth may lead to nutrient deficiencies in pregnant cattle. Compromised maternal nutrition can impact fetal muscle development, body weight gain, hot carcass weight, back fat and marbling. Vaccination strategy may also impact carcass outcomes of the offspring. Carcass evaluation is necessary to determine if these reactions persist until slaughter.
