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 [email protected]

Completed Research

Early diarrhea syndrome and vitamin D

Project 20-08 - Dr. Tim Blackwell, OMAFRA

In this trial, there was no improvement in the response to prophylactic treatment of newborn pigs with early neonatal diarrhea when 40,000 I.U. of vitamin D was added to the existing yogurt prophylaxis. 

Development of boar taint detection kits using DNA aptamers for use in commercial packing plants. Phase 1: Lab validation

Project 20-006 - Dr. Maria DeRosa, Carleton University

DeRosa has developed aptamers (artificial receptors) for two compounds implicated in boar taint (androstenone and skatole) and a prototype lateral flow device (dipstick test) for use in pig carcass testing. 

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 - Lead Researcher: Dr. Tim Blackwell, Ontario Ministry of Agriculture, Food and Rural Affairs

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.

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

Project 19-004 - Lead Researcher: Dr. 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- Lead Resesarcher: 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.

Protein and non-protein methionine requirements for first parity gestating and lactating sows

Project 18-02 - Lee-Anne Huber, University of Guelph

The NRC (2012) based estimated methionine requirements for gestating and lactating sows from very few studies, with a focus on the retention of methionine in maternal, fetal, and milk proteins. These estimates do not take into account the metabolism of the modern sow (many studies are over 50...

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

Project 17-022 - Lead Researcher: Dr. Joshua Gong, Agriculture and Agri-Food Canada, Guelph

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

Project 17-016 - Lead Researcher: Dr. Tim Blackwell

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...

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

Project 17-011 - Lead Researcher: Dr. 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...

Development of evidence-based mental health literacy program and emergency mental health response model for Ontario agriculture

Project 16-014 - Lead researcher: Andrea Jones-Bitton, University of Guelph

Farming is recognized as a stressful occupation both in the routine daily tasks and during an emergency. For livestock producers, disease outbreaks can have significant economic and emotional consequences stemming from the loss of production and the loss of animals through mortalities and the...

Assessing the efficacy of ketoprofen and meloxicam when mixed with iron dextran on pain relief following castration in piglets

Project 16-011-Lead researcher: Terri O’Sullivan

The Canadian Code of Practice for the Handling and Care of Pigs states that pigs are to receive analgesics (pain control medication) to control post-procedural pain. The pain control medications ketoprofen (Anafen®) and meloxicam (Metacam®), are approved for use in pigs in Canada. The...

Precision Feeding of Gestating Sows: Use of Electronic Sow Feeders to Reduce Feed Costs and Nutrient Losses into the Environment, While Improving Sow Productivity and Welfare

Project 16-004 - Researchers: Ira Mandell and Lee-Ann Huber, University of Guelph

The ultimate goal of this work is to examine how sow management using ESF can influence lifetime sow productivity and retention in the herd, and carry-over effects on to her progeny.
