【 摘 要 】

The objective of this study was to evaluate the effect of including guava wastes in the feed on the performance and carcass yield of broiler chickens. An experiment was carried out with 300 male Cobb strain chicks, in a randomized complete design with five levels of waste and five replications. A reference diet based on corn and soybean meal and four feeds with 3, 6, 9 or 12% guava waste were evaluated. The feed intake, weight gain and feed conversion were assessed weekly; the weight at slaughter and the weight and yield of eviscerated carcass, carcass without feet and head, breast, drumstick, thigh, wing, back, edible viscera and abdominal fat were assessed. The inclusion of guava waste in the feed promotes performance and carcass yield similar to that obtained with the feed based on corn and soybean meal, therefore this agro-industrial by-product can be used at levels of up to 12% in feeds for broiler chickens.
