Poultry Differences in Amino Acid Digestibilities

Australian researchers determined the apparent ileal digestibility of several feed ingredients using broilers, layers and roosters. Each diet was formulated with the test ingredient supplying the sole source of protein. The mash diets were fed ad libitum to five replicated pens of broilers and layers and four replicated pens of roosters. The digestibility of amino acids in soybean meal was higher (P<0.05) for layers compared values for broilers and roosters; values for broilers and roosters were similar. The researchers indicated that the results suggest that the class of poultry significantly influenced the apparent digestibility of amino acids.
