Abstract

Two experiments were conducted with the aim of investigating whether non-nutritive suckling (suckling without milk ejection), when included into a regular rhythm of suckling with milk ejection, affects milk intake and liveweight gain during early lactation in pigs. In experiment 1, when the piglets were 9-12 days old, 8 sows were forced to suckle every 70 min 3-times in succession. Between sucklings, 2 piglets had an additional opportunity to massage the sow's teats from which they had been suckling. Milk intake was estimated by the weigh-suckle-weigh method. Additional massage on the 2 teats had no influence on milk output from these teats during subsequent suckling. In experiment 2, on day 7 or 8 post partum, 16 sows were forced to suckle at every 70 min for 24 h. In 9 of the sows (group MIN70 + 15), non-nutritive suckling was induced 15 min after each nutritive suckling. In the other group of 7 sows (MIN70), there was no opportunity for this additional massage. The total duration of udder massage was considerably longer in group MIN70 + 15 (median 271 min vs. 165 min, Mann-Whitney U-test, P<0.005) than in MIN70. Nevertheless, the liveweight gain during the whole 24-h period was similar in both groups (157 vs. 141 g, Mann-Whitney U-test, not significant). Both groups showed a similar decrease in liveweight during the 24-h manipulation of suckling rhythm compared with liveweight gain during an unmanipulated period of 24 h 1 day before (group MIN70 + 15 decreased 28% and group MIN70 decreased 31
