1274 Impact of the Birth Weight of Landrace x Large White Dam Line Gilts on Mortality, Culling and Growth Performance until Selection for Breeding Herd Diogo Magnabosco1, Evandro César Pereira Cunha1, Mari Lourdes Bernardi2, Ivo Wentz1 & Fernando Pandolfo Bortolozzo1 ABSTRACT Background: Piglets weighing less than 1 kg have become a common occurrence in pig farms due to selection for increasing litter size.
Large litters imply a decrease in the mean piglet birth weight and an increase in the within-litter variability of birth weight with a greater risk of mortality and lower growth performance.
The aim of this study was to evaluate the effects of birth weight of female piglets on growth performance and on removal rates until selection for entry into the breeding herd (170 days) of Landrace x Large White crossbred gilts. Materials, Methods & Results: A total of 1495 Landrace x Large White (DB 25® - DanBred) crossbred female piglets were individually weighed after birth (BiW) and housed on the same farm from birth onwards.
