Weaner pig in nursery


Research shows that if pigs go over 36 hours without eating or drinking in the nursery, their survival rates plummet.1 Weaning stress reduces appetite, weakens immunity and heightens the risk of illness and mortality.

1. Nursery Pig Management SDSU Extension


A customer field demonstration was conducted using over 12,000 mixed sex pigs across 6 finishing groups. Pigs were fed 1 of 2 dietary treatments: ProsperEO at a rate of 0.5 lbs./ton of finished feed or a control diet for the entire grow-finish period. ​
