Kansas Agricultural Experiment Station Research Reports
A total of 1,890 growing-finishing pigs (PIC; 359 × 1050; initially 59.8 ± 1.3 lb) were used in a 124-d growth trial to compare the effects of high-protein distillers dried grains (HPDDG) or conventional distillers dried grains with solubles (DDGS) on growth performance and carcass characteristics. Conventional DDGS contained 29.0% CP, 0.48% standardized ileal digestible (SID) Lys, and 9.2% oil, whereas HPDDG contained 39.3% CP, 0.68% SID Lys, and 11.1% oil. All diets were formulated on an equal SID Lys-basis with diets containing HPDDG having less soybean meal than diets with conventional DDGS. There were 27 pigs per pen and …

Effects Of Standardized Ileal Digestible Tryptophan:Lysine Ratio On Growth And Carcass Performance Of Finishing Pigs Fed Ractopamine Hcl, H. E. Williams, M. D. Tokach, S. S. Dritz, J. M. Derouchey, J. C. Woodworth, R. D. Goodband, J. A. Soto
Kansas Agricultural Experiment Station Research Reports
Recent research has reported that increasing standardized ileal digestible (SID) Trp:Lys ratio above 20% in finishing pigs fed ractopamine HCl (RAC) resulted in improved growth and carcass performance, however, this response has been inconsistent. Therefore, the objective of this study was to evaluate the effects of feeding high SID Trp:Lys ratios with RAC on growth and carcass performance. A total of 1,791 finishing pigs (PIC 1050 × 337, initially 245.1 lb BW) were used in a 27-d study to evaluate the effects of feeding high SID Trp:Lys ratios on growth and carcass performance of pigs fed ractopamine HCl (RAC, Paylean, …
