Abstract

Feed is the largest variable cost in pork production. Although selection for growth and leanness has resulted in increased feed efficiency (Sather and Fredeen 1978), further improvement requires measurement of feed intake on individual pigs. Measurement of individual feed intake on pigs housed in groups can be accomplished by electronic feeders (Young and Lawrence 1994). Electronic feeders are single-space feeders that offer protection from competition, depending on the design of the feeder. In contrast, multi-space feeders that offer no protection are used in commercial herds. There are also design differences that may result in differences in feed wastage. Knowledge of performance of pigs fed using electronic versus commercial feeders is needed to detect genotype by environment interactions and to ensure that genetic progress achieved in selection herds is realized at the commercial level
