Effects of Varying Nutrient Density on Broiler Performance Using Computer-Formulated Rations

Broiler cockerel chicks were fed computer-formulated commercial-type starter and grower diets varying in nutrient density by 10%. At 8 weeks of age similar weights were obtained for all but the lowest density diet; however, feed:gain ratios showed a linear improvement as the density of the diets was increased. Carcass grades indicated that as the density of the ration was increased there was a definite shift to carcass of a higher quality.
