Effect Of Soybean Meal From Different Midwest Soybean Varieties On Growth Performance Of Broilers, Kara M. Dunmire, Michaela B. Braun, Caitlin E. Evans, Charles R. Stark, Chad B. Paulk

Kansas Agricultural Experiment Station Research Reports

At hatch, 360 one-d old Cobb500 male broilers were placed in battery cages to determine the effect of soybean meal (SBM) from different Midwest soybean varieties on growth performance of broilers. There were 6 broilers per cage and 15 replicates per treatment. Dietary treatments cons0isted of 1 of 4 soybean sources varying in quality determined by crude protein (CP) content and processed into SBM. Two sources consisted of soybeans from a similar region and processed either commercially solvent extracted or experimentally solvent extracted at Texas A&M University. Additional sources included a low quality and high quality soybean, experimentally solvent extracted …

Protein is one of the most expensive nutrients in poultry diets. In an effort to minimize feed costs, protein digestion and utilization by the animal must be carried out as efficiently as possible. Therefore, the objective of this study was to evaluate the effects of dietary AA density and exogenous protease inclusion on growth performance and AA digestibility in broilers. Treatments consisted of a 2 × 4 factorial design with main effects of commercial protease (with or without) and digestible Lys (1.12, 1.15, 1.18, or 1.21%). Broiler chicks were housed in 4 Petersime batteries and treatments were randomly assigned to …
