Abstract

The effects of feed enzymes and feeding regimens on nutrient digestibility, growth, visceral organ weight (VOW), gutfill and carcass and meat quality were studied in growing-finishing pigs. Feed enzymes in a barley-canola meal-based diet (BCM) did not affect ileal nutrient digestibility in growing pigs. In a performance study using 128 finishing pigs fed either a BCM or a corn-soybean meal-based diet (CSBM), feed enzymes did not affect nutrient digestibility, gain to feed (G:F) or daily gain (DG). Pigs fed CSBM had better G:F, lower VOW and gutfill, but similar daily digestible energy intake (DEI) and DG compared to BCM fed pigs. Feeding a casein-cornstarch diet (CC) starting 12 d pre-slaughter improved DG and (DEI) but not G:F. Limit feeding (2 kg/pig/d) or feeding CC preslaughter reduced gutfill and VOW in pigs previously fed BCM but not in pig previously fed CSBM. Carcass and meat quality were unaffected by feeding regimen.
