Valores de energia metabolizável de alguns alimentos obtidos com aves de diferentes idades

摘要: Four assays were carried out to determine the apparent metabolizable energy (AME) and corrected nitrogen (AMEn) of ten feeds for poultry at different ages. The studied were: corn grain, soybean meal, ground sorghum, wheat bran, integral rice two kinds feather viscera meal spray-dried plasma. method total excreta collection was used AME AMEn values. broiler chicks distributed on a completely randomized experimental design, with 11 treatments, six replications, number animals by replication according assay. In first assay, 528 male in period from 10 17 days age used, eight per replication. second 396 26 33 third 264 40 47 four fourth 132 roosters replicate. There an effect values following feeds: plasma, where oldest broilers provided highest Wheat bran affected only
