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 ( …
Comparing Increasing Tryptophan:Lysine Ratios In Ddgs-Based Diets With Or Without A Ddgs Withdrawal Strategy On Growth Performance And Iodine Value Of Growing-Finishing Pigs, Mikayla S.

Kansas Agricultural Experiment Station Research Reports
A total of 6,240 pigs (DNA 600 × PIC 1050; initially 49.7 × 2.23 lb), divided into 2 groups, were used in a 119- or 120-d study to compare increasing the Trp:Lys ratio in diets with DDGS or a DDGS withdrawal strategy on growth performance and carcass fat iodine value of grow-finish pigs. Pigs were randomly allotted to 1 of 7 dietary treatments with 30 to 36 pigs per pen and 26 replications per treatment. Diets were fed in 4 phases (approximately 50 to 96, 96 to 157, 157 to 220, and 220 lb to market). Diets included a control …
Effects Of Increasing Soybean Meal And Valine:Lysine And Tryptophan:Lysine Ratios On Finishing Pig Performance, Macie E. Reeb, Jamil E. G. Faccin, Robert D. Goodband, Jason C. Woodworth, Joel M. Derouchey, Mike D. Tokach, Jordan T. Gebhardt

Kansas Agricultural Experiment Station Research Reports
A total of 621 pigs (DNA 241 × 600; initially 138.0 ± 5.5 lb) were used in a 65-d growth trial to determine the effect of increasing soybean meal (SBM) and Val:Lys and Trp:Lys ratios on finishing pig performance. Experimental diets were corn-soybean meal-DDGS-based and fed in 3 phases. The 6 dietary treatments were arranged in a 3 × 2 factorial with main effects of SBM level (low, medium, high) and Val:Lys and Trp:Lys ratios (standard and high). The additional amino acids (AA) provided by increasing levels of SBM in diets with standard AA ratios were expected to result in …
