The influence of feeding level during lactation and the following pregnancy on the reproductive performance of sows



The influence of feeding level during lactation and the following pregnancy on the reproductive performance of sows



Agriculture and Forestry Bulletin, University of Alberta (Special Issue): 59-61



123 second-parity Yorkshire X Landrace sows were given 3 or 6 kg feed per day from farrowing to the end of a 28-day lactation. Litter size differences were minimised by crossfostering. The decrease in backfat thickness from farrowing to weaning in the 2 groups averaged 6.8 and 3.6 mm resp., and body weight loss 26.5 and 13.7 kg. Diet did not significantly affect ovulation rate.
