Evaluation of two feeder designs for growing pigs

Two feeder types for self-feeding of grower-finisher pigs were assessed using behavioural and production criteria. The 2 types were a round feeder providing 9 feeding spaces and a 2-space rectangular feeder which allowed the pigs to hide the whole head. Feed utilisation did not differ between feeder types, and relative growth rate (%) corrected for initial body weight was the same for both feeders. Feeder use was similar for both types of feeder and was higher in the afternoon. The frequency of agonistic interactions were the same at both feeders.
