dc.description.abstract | The objective of this research was to evaluate nutrient digestibility, growth performance, and processing yields of Ross × Ross 708 male broilers fed diets formulated with low oligosaccharide soybean meal (LOSBM) and ultra-low oligosaccharide soybean meal (ULSBM). Experiments 1 through 4 determined the AMEn and digestible amino acid (AA) composition of a control soybean meal (CSBM), LOSBM, and ULSBM from 27 to 31 d of age. In experiments 1 and 3, LOSBM had increased (P = 0.011) AMEn and higher (P = 0.002) digestible AA concentrations compared with CSBM. Experiments 2 and 4 were expanded to evaluate ULSBM. Low oligosaccharide SBM had greater (P = 0.012) AMEn compared with CSBM and ULSBM. Both LOSBM and ULSBM had higher (P < 0.001) digestible AA concentrations compared with CSBM, while ULSBM had greater (P < 0.05) concentrations of digestible AA compared with LOSBM. Experiments 5 and 6 evaluated feeding diets formulated with CSBM, LOSBM, or ULSBM during a 6 wk production period using nutrient values determined in experiments 1 through 4. In experiment 5, broilers fed diets containing LOSBM or CSBM had similar growth and carcass characteristics. Dietary fat inclusions were reduced over 50% in all feeding phases in diets formulated with LOSBM. In experiment 6, diets were formulated with CSBM, LOSBM, or ULSBM and moderate or reduced (-25 kcal of AMEn/kg) energy concentrations. No negative effects on growth performance or carcass characteristics were observed for broilers fed diets formulated with the 3 SBM types or moderate or reduced energy concentrations. Diets formulated with LOSBM and ULSBM contained up to 70% less supplemental fat compared with CSBM-based diets. Formulating diets using LOSBM and ULSBM compared with CSBM reduced the amount of supplemental fat inclusion with no adverse effects on broiler performance and processing yields. | en_US |
