Feeder Use Patterns in Group-Housed Pregnant Sows Fed With an Unprotected Electronic Sow Feeder (Fitmix)

Feeder Use Patterns in Group-Housed Pregnant Sows Fed With an Unprotected Electronic Sow Feeder (Fitmix)


Previous studies on feeder use in group-housed pregnant sows focused on dynamic groups and protected electronic sow feeders (ESF). This study observed 60 pregnant sows, 1st to 8th parity—housed from Day 29 of pregnancy to 1 week before parturition in stable groups of 20 animals, 1 Fitmix feeder per group. Data from 25 nonconsecutive 24-hr feeding cycles showed sows making several visits to the feeder. Literature on conventional ESF indicated shorter daily feeder occupation. Daily feeder occupation per sow decreased over time ( p < .001). The study observed maximum feeder activity in the hours following the start of each feeding cycle. During the experiment, there was a relatively stable, quickly established, and maintained feeder order ( W > 0.80, p < .001). This highly correlated with dominance rank ( r s = 0.80, p < .001). High-ranking sows fed earlier and made as many—but longer—visits as low-ranking sows; thus, they occupied the feeder more time every day ( p < .01). Although optimization of the feeder efficiency may take several weeks, Fitmix seems an efficient feeding system for medium-size, stable groups of sows.
