Studies in sow reproduction. 3. The effect of nutrition between weaning and remating on the reproductive performance of multiparous sows

Abstract

SUMMARYAn experiment was conducted using 176 sows at three centres to investigate the effect of post-weaning feed level on reproductive performance. At two centres sows weaned 35 to 56 days after farrowing received 1·8, 2·3, 3·6 or 4·5 kg food/day from the day following weaning until the day following the last mating at the post-weaning oestrus.At the third centre sows were rationed to 1·8, 2·3 or 3·6 kg food/day or given all they would consume in a single 1-hr feeding period each day. Reproductive performance of the sows was not significantly affected by post-weaning feed level.
