Abstract

The aim of this study was to evaluate bromatological composition and metabolizable energy values of cottonseed meal, rice meal, and wheat bran when provided to slow growth rate broilers at different ages. Energy values of 15- to 25- and 35- to 45-day-old broilers were determined by the total feces collection method using two digestibility bioassays. The birds were distributed in a completely randomized experimental design to evaluate the age effect, with six replicates of 10 chickens each, for each ingredient. Values of apparent metabolizable energy adjusted by nitrogen balance (kcal/kg), for the first and second ages were: 1,255 and 1,564 for cottonseed meal, 3,124 and 3,301 for rice meal, and, 2,211 and 2,383 for wheat bran, respectively. The ingredients showed some variations regarding chemical composition and energy values, which were higher (P < 0.05) in older broiler chickens.
Keywords: energetic value, feed chemical composition; free-range broiler, total excreta collection
