Book Description
Six experiments using 3,862 pigs were conducted to evaluate effects of ractopamine HCl (RAC) feeding programs, dietary L-Carnitine and dried distillers grains with solubles (DDGS) on growth, carcass traits, loin and jowl fat quality of pigs, and energy and protein sources in nursery diets. In Exp. 1 and 2, RAC-fed pigs had greater (P

Book Description
This study was conducted using 65 pigs to measure the effects of ractopamine hydrochloride (RAC) on growth and carcass characteristics of lightweight swine. Beginning weights averaged 68.23 kg. RAC was included in the diet at 0, 5, and 10 ppm for 25 days until an average weight of 92 kg. Last rib fat thickness was lower (P0.05) for the 5 ppm and 10 ppm groups. No other differences (P0.05) were found between treatment groups for growth, feed efficiency, carcass cutability, or pork quality traits. These results suggest that feeding ractopamine hydrochloride in lightweight swine diets can reduce last rib fat while not impacting growth or other carcass traits.

Book Description
Four experiments were conducted to investigate the effects of ractopamine on amino acid (AA) requirements for finishing pigs. The specific AA that were investigated were lysine and threonine. Exp. 1 investigated the effects of increasing lysine concentrations for barrows fed ractopamine diets during the late finishing phase in order to estimate the appropriate requirement for optimal growth response. Exp. 2, 3, and 4 investigated the effects of increasing the threonine to lysine ratio of diets with ractopamine on growth, carcass data, and plasma urea N concentrations and estimated the optimal threonine to lysine ratio for maximum growth rate. All experiments used individually fed barrows and corn-soybean meal based diets. In Exp. 1, 36 pigs were allotted to 6 dietary treatments with 0 or 10 ppm ractopamine and increasing levels of lysine. In Exp. 2 and 3, 63 pigs were allotted to 7 dietary treatments with 0 or 10 ppm ractopamine, different lysine, and increasing threonine concentrations. For Exp. 4, 35 pigs were allotted to similar diets as Exp. 2 and 3 that were limit fed 3 kg/d. In Exp. 1, a total lysine intake of 24.7 g/d was adequate for obtaining maximal growth for barrows fed ractopamine. In Exp. 2, 3, and 4, there were effects on intakes and growth rates due to increasing threonine to lysine ratios (P
