An 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.
