The objective of this study was to evaluate the chemical composition, metabolizable energy, the digestibility coefficients of dry matter, crude protein and the amino acids contained in yeast extract supplied to broiler chickens. Two metabolism assays were carried out. In the first assay, 200 14-day old Cobb-500® male broiler chickens were used kept in metallic cages in a randomized complete design in groups of 10 birds per experimental unit. The total excreta collection method was used to determine the apparent […]

The coefficients of apparent (CADP) and true (CTDP) digestibility of phosphorus of eleven plant feed of vegetal origins commonly used in swine feeds were determined in this research. Seventy eight crossbred barrows were distributed to completely randomized experimental design, with a factorial arrangement 2 × 2 × 13 (methodology × phase × treatment) with three replicates per treatment. The digestibility coefficients were evaluated by using simultaneously both methodologies, total fecal collection and fecal marker (Cr2O3), in two production periods, growing […]
