Abstract

We conducted a biological assay using the traditional method of excreta collection, with the purpose to determine the values of apparent metabolizable energy, apparent metabolizable energy corrected for nitrogen balance, and the chemical composition of six feeds: deactivated whole soybean with shuck; deactivated whole soybean without shuck; soy protein concentrate; extruded semi-whole soybean meal; soybean meal; and wheat gluten. We used 252 chicks of the Cobb 500 commercial lineage, from 14 to 24 days of age, distributed in a completely randomized design, with seven treatments (six test rations and a reference ration) and six repetitions with six birds per experimental unit. The five initial days were destined to the adaptation of the birds to the experimental rations, and the five final days were destined to excreta collection, which was carried out twice a day. The values of  apparent metabolizable energy corrected for nitrogen balance, based on natural matter determined in broiler chicken aged from 14 to 24 days old were as follows: deactivated whole soybean with shuck: 2797 kcal/kg; deactivated whole soybean without shuck: 3012 kcal/kg; soy protein concentrate:, 2554 kcal/ kg; extruded semi-whole soybean meal: 2467 kcal/kg; soybean meal: 2221 kcal/kg and wheat gluten: 3813 kcal/kg.

Keywords: deactivated whole soybean; extruded semi-whole soybean meal; soy protein concentrate; soybean meal; wheat gluten.
