Enhancing Piglet Immunity through Sow Vitamin Supplementation

Researchers from Agriculture and Agri-Food Canada, CDPQ, and the Western College of Veterinary Medicine are investigating the effects of increased vitamin supplementation for sows during gestation. This study aims to improve piglet immunity against diarrhea by enhancing the immune response to vaccinations, potentially reducing the need for antibiotics and high levels of zinc oxide in their diet. Early findings suggest positive outcomes, and detailed results will be shared at industry events and published in academic journals.

Dr. Martin Nyachoti from the University of Manitoba highlighted that preliminary data indicates piglets born to supplemented sows exhibit stronger immune responses and better health. The goal is to provide a practical, cost-effective solution to common piglet health issues, benefiting both animal welfare and farm productivity.

Video: Leman Swine Conference: Vaccination strategies to reduce PRRS virus recombination

Dr. Jay Calvert, Research Director with Zoetis, recently spoke to The Pig Site’s Sarah Mikesell at the 2023 Leman Swine Conference in St. Paul, Minnesota, USA, about his conference presentation on porcine reproductive and respiratory syndrome (PRRS) virus recombination.

“The number one problem in PRRS these days from a vaccine point of view is the emergence of new strains of PRRS. Since the beginning, we have had new strains and a lot of diversity,” said Dr. Jay Calvert. “We thought we knew it was all about mutation changes in amino acids and the individual strains over time, but they take on new characteristics.”

With the onset of more common whole genome sequencing and recombination analysis, Dr. Calvert says there is another mechanism, and recombination seems to be a key factor.
