Description
Summary:An abstract of a study by J. A. Feldpausch et al about the birth weight threshold for identifying piglets at-risk for preweaning mortality is presented. Here, Feldpausch et al identify a birth weight (BtW) threshold associated with reduced odds of preweaning survival. Observations from 2 studies with a total of 4068 piglets originating from 394 litters on 4 different commercial farms (3 European, 1 U.S.) were compiled for meta-analysis. Overall preweaning mortality rate across all farms was 12.2%. Result shows that increasing the BtW of piglets having BtW less than 1.11 kg have tremendous potential to improve piglet preweaning survivability. A large percentage of the neonatal pig population falls below this weight threshold, and postnatal management strategies to decrease neonatal mortality should be directed toward these at-risk piglets.
