Abstract

Pre-weaning piglet mortality continues to be a major welfare and economic concern. In outdoor farrowing systems, there is a particular need to broaden breeding goals by incorporating selection for piglet survival to improve both productivity and welfare.

Data were collected from 511 piglets from Large White x Landrace x Duroc sows and Generalised Linear Mixed Models determined which indicators were most important for piglet survival in an outdoor system.
