Kansas Agricultural Experiment Station Research Reports
A total of 21 litters (early or late maturing Duroc × DNA 241) and 247 pigs were used in 170-d trial to determine the effect of sire line growth pattern (early vs. late maturing) and creep feeding on the stress response, intestinal permeability, and growth performance of nursery and finishing pigs.Treatments were arranged in a 2 × 2 factorial with main effect of Duroc sire line (early or late maturing) and lactation creep feeding (with or without). Immediately after weaning (initially 14.0 lb), blood cortisol levels were increased (P<0.01) in late maturing pigs compared to early maturing pigs, indicating an increased stress response. A greater percentage (P<0.001) of late maturing pigs lost weight from d 0 to 3 post-weaning compared to early maturing pigs. Likewise, early maturing pigs had improved ADG (P<0.001) and ADFI (P<0.001) during the first 3 d in the nursery. A similar response was observed in daily feed intake with early maturing pigs having increased daily feed intake (P<0.001) for the first 14 d in the nursery. However, no differences were observed in intestinal permeability between treatments. For overall nursery growth performance, a significant interaction was observed for ADG (P= 0.007) and ADFI ( …
