Completed Research

Development of an oral vaccine for piglets: A platform technology

Project:11-228 - Researcher: Heather Wilson

The most significant protective response provided was seen in body systems like the bloodstream, similar to traditional vaccines, but some protective responses were also seen at digestive surfaces. With these positive results, researchers then focused on trying this new type of oral vaccine...

Comparison of single timed artificial insemination (AI) in gilts using OvuGel-ELANCO (triptorelin acetate) or PG600-MERCK (eCG/pLH) to synchronize ovulation

Project 16-003 - Lead Researcher: Bob Friendship

Optimal sow fertility is during the 24-hour period before ovulation. Use of the ovulation synchronization protocols may be a good tool for producers looking for options to improve overall herd reproductive performance or reduce their time in the breeding barn

Canadian Health Claim Feasibility Assessment Report for Pork Products

Project:13-008 - Researchers: Krista Coventry-Nutrasource Diagnostics

Identifying possible opportunities to make health claims and the steps needed to position pork as a healthful and nutritious protein option may be one way to promote and increase domestic pork consumption. In particular a proven health claim to pork could be used to contest recent research...

Benchmarking performance in Ontario swine nursery barns

Project 16-002 - Researchers: Robert Friendship, Terri O’Sullivan, Zvonimir Poljak, Vahab Farzan, Tim Blackwell

The overall conclusion of this work is that there is wide variation in nursery performance which suggests that there is opportunity for herds to improve. Likewise disease status varies considerably and there needs to be efforts made to improve the immune status of newly weaned pigs and to...

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...

An investigation into the effects of in-feed zinc oxide on antimicrobial resistant bacteria

Project 13-011 - Lead Researcher: Bob Friendship

Staphylococcus aureus is a common bacteria that is the leading cause of skin infections and pneumonia in people. The increase in drug-resistant bacteria such as Methicillin resistant Staphylococcus aureus (MRSA) have increased the burden on healthcare systems due to an inability to find an...

An epidemiological investigation of the early phase of the porcine epidemic diarrhea (PED) outbreak in Canadian swine herds in 2011

Project 14-007 - Researcher: Dr. Terri O’Sullivan

In January 2014, the first case of porcine epidemic diarrhea virus (PEDV) was reported in an Ontario swine herd; which was soon followed by a series of other cases.  Feed from a single feed company was implicated as a source of the virus during the early phase of the outbreak.  The...

A Comparison of the Multi-class, Multi-residue Drug Analysis (MRD) and the Charm Kidney Inhibition Swab (KIS) Test Supporting Detection and Identification of Antimicrobial Drugs.

Project 11-225 - Researcher: Mark Mitchell

The results demonstrate that the KIS test is able to acuratly indicate the presence of antimicrobial residue if it is at the acceptable residue limit or greater but the MRD test can identify antimicrobial residue at low levels and can name the specific drug found and the amount present.
