Active 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

Active Research

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

Project 21-04 - Dr. Pawel Bartlewski

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...

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,...

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

Project 17-006 - Lead Researcher: Dr. Brandon Gilroyed, University of Guelph, Ridgetown Campus

Pork production contributes about 9% of total manure production in the Canadian livestock sector. During storage and land application manure undergoes natural degradation leading to the emission of greenhouse gases (GHGs) such as methane(CH4) and nitrous oxide (N2O), as well as pollutants such...

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.

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

Project 19-005 - Lead Researcher: Dr. 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.

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

Project 20-007 - Dr. 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.

Improvement of feed efficiency in Canadian swine industry through genomics and machine learning

Project 21-01 - Dr. Younes Miar

Feed is the largest cost of pork production in Canada and therefore improving feed efficiency (FE) is essential to boost the Canadian pig producer profitability. Additionally, improving FE increases industry competitiveness, decreases demand on global feed resources, and complements...

Evaluation and improvement of Streptococcus suis bacterins

Project 19-006 - Researchers: Dr. Mariela Segura and Dr. Marcelo Gottschalk, University of Montreal

We propose to study and compare the immune response and protection generated by an autogenous vaccine formulated with different adjuvants under controlled conditions using experimental challenge of piglets.  An improved vaccine strategy will have an impact on swine health and welfare,...

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...

Efficacy of exogenous alkaline phosphatases to improve growth performances in pigs

Project 17-032 - Lead Researcher: Dr. Ming Fan, University of Guelph

The effects of systemic inflammation are well documented to adversely affect efficiency of energy and nitrogen utilization in pigs.  Weaned and grow-finish pigs are likely commonly experiencing mild inflammatory responses within the body, to the various challenges they experience (stress at...

Effects of improved design trailers on the welfare of pigs transported under Canadian transport and climate conditions

Project 17-012 - Lead Researcher: Dr. Luigi Faucitano

Pig losses during transit are largely dependent on vehicle design. This is particularly the case in Canada where most pigs are transported in pot-belly (PB) trailers. This vehicle type is questioned as it is not easy to load and unload due to the presence of multiple and steep ramps and provides...

Development of evidence-based feeding strategies for lactating sows using novel and evolving feeding technologies

Project 20-002 - Dr. Lee-Anne Huber, University of Guelph

Dr. Lee-Anne and team intend to “test improvements” in lactating sow feeding programs and technologies in order to support producers as they consider installing precision feeding technologies for (lactating) sows on-farm.

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. 

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...

Development of an in vitro / in vivo correlation method to assess the efficiency of oral drug release from oral medications in swine - Phase 2: Water medication

Project 21-03 - Dr. Jerome del Castillo

Phase 2: Water medication. Project extends the range of tested feedstuffs to those used in the manufacturing of early (1st, 2nd) and late (3rd, 4th) phase weaner diets, determine their abilities to bind the drug molecules of water medications for weaner pigs, and determine the reversibility of...
