Summary
PRRS virus is one of the costliest diseases for pig producers. When it hits a sow herd, newly weaned piglets often get sick fast — and without quick action, mortality rates can climb. Researchers in Quebec tested whether adding Tylvalosin (Aivlosin®) to drinking water could help nursery pigs fight through a natural PRRS outbreak. Half the pigs received the water treatment alongside a standard feed antibiotic; the other half received only the feed antibiotic. The results were promising. Nursery mortality dropped from 10% to 4% in treated pigs, and fewer pigs needed individual antibiotic injections. Survival rates from nursery to market also improved significantly. For producers dealing with PRRS, adding Tylvalosin to drinking water could be a practical, straightforward tool to reduce losses and cut down on injection treatments — without affecting daily gain or feed efficiency.
