Completed Research

Ontario Pork has a call for research proposals once a year. These projects were approved for funding by the board on recommendation of the research committee. If you have questions or need further information about the research posted here please contact Jessica Fox at jessica.fox@swinehealthontario.ca

Completed Research

Ultrasonographic determination of chemical composition and physical properties of meat in fattener pigs

Project 21-04 - Pawel Bartlewski, University of Guelph

Project examines relationships between the physical and chemical properties of the pigs' latissimus dorsi and semimembranosus muscles, and quantitative characteristics of their corresponding ultrasound images determined with the use of commercially available image analytical software...

Early diarrhea syndrome and vitamin D

Project 20-08 - Tim Blackwell, OMAFRA

Although initially there was an early clinical impression that the yogurt treatment had decreased the incidence of diarrhea, this was later attributed to weekly variation in syndrome severity.  It was suggested by the manufacturer of the Wean-D product that the addition of vitamin D could...

Improving post-weaning performance of nursery pigs through a feeding system designed to be compatible with normal weaned pig feeding behavior

Project 20-007 - Tim Blackwell, OMAFRA

This project will imitate multiple hand feedings by adding a special controller to the standard Rondomat nursery feeder. Closely approximating natural feeding behaviour improves piglet vigour after weaning and reduces the need for antimicrobials.

A pilot study to identify common pig to feeder space ratios in Ontario nursery and finisher barns and investigate their relationship to productivity and welfare

Project 19-007 - Tim Blackwell, OMAFRA

This study looks to identify both common and appropriate pig to feeder space ratios as well as factors that drive appropriate pen utilization will improve swine productivity and welfare on Ontario swine farms.

Molecular characterization of Streptococcus suis isolates recovered from Ontario nursery pigs between 2013 and 2018: Towards development of an effective vaccine

Project 19-005 - Vahab Farzan, University of Guelph

The project will apply these advanced analytical methods to help identify the most important virulence-associated-factors and use this knowledge in an attempt to develop a universal vaccine for S. suis in pigs.

Development of an vitro / in vivo correlation method to assess the efficiency of oral drug release from medicated feeds in swine

Project 19-004 - Jerome del Castillo, University of Montreal

The goal of this project is to develop testing methods that will identify feed ingredients or manufacturing practices that decreases the release of a medication to the pig. The optimization of medicated feed manufacturing will improve its therapeutic efficacy, hasten the recovery of treated...

Impact of a specialized feeding regime for replacement gilts on lactation performance

Project 18-007- Robert Friendship, University of Guelph

Sow milk production is becoming increasingly important with the use of hyperprolific sows and resulting large litters. The use of a high fibre feeding program fed ad libitum can be utilized to control the growth of developing gilts without impairing subsequent lactation performance.

Assessing carcass variability in Ontario pork and the potential to increase returns to producers and improve pork quality

Project 18-003 - Benjamin Bohrer, University of Guelph

Dr. Bohrer will be the first researcher examining use of an advanced ultrasonic image analyzer (AutoFom III; Denmark) in a commercial Canadian pork facility (Conestoga Meat Processors) for determination of lean yield.

Establishing sensitivity and specificity of using rope samples (saliva) to test for PRRS virus antibodies

Project 17-016 - Tim Blackwell, OMAFRA

Porcine Reproductive and Respiratory Syndrome (PRRS) causes disease and economic losses on swine farms. Producers strive to eradicate the virus if geographically feasible or “stabilize” the sow herd through vaccination or intentional field virus exposure. A cornerstone of any PRRS...

Strategies for detoxifying vomitoxin using innovative chemical and biological approaches in post-weaning piglets

Project 17-022 - Joshua Gong, Agriculture and Agri-Food Canada

The contamination of feed with the mycotoxin, deoxynivalenol (DON), has detrimental effects on the production of farm animals, with pigs being the most susceptible. Typical negative effects of mycotoxin consumption includes reduced feed intake, digestive dysfunction (e.g. gastroenteritis,...

Establishing value/utility of soluble CD163 as a biomarker for predicting PRRS-induced disease severity in swine herds

Project 17-011 - John Harding, University of Saskatchewan

The swine industry is economically burdened by porcine reproductive and respiratory syndrome (PRRS) and PRRSV-induced coinfections partly due to the lack of fully protective vaccines and also by the absence of a reliable method to distinguish disease-susceptible (moderately to severely affected...

Reducing pathogens and greenhouse gas emissions from swine manure using anaerobic digestion

Project 17-006 - Brandon Gilroyed, University of Guelph, Ridgetown Campus

This project investigated process performance of a plugflow reactor (PFR) configuration co-digesting swine manure and biomass pellets. Although organic matter reduction efficiency decreased with an increase in organic loading rate (OLR) and total solids (TS), process stability was evident...
