| description | <span>An experiment was conducted using 276 free-range broiler chickens of the Gauchão lineage to evaluate the effect of dietary supplementation with ground sugarcane (GSC) on performance, energy value of the diets, and carcass yield. The animals were assigned to three treatments and four repetitions of 23 animals each in a completely randomized design. The treatments consisted of the on-top inclusion or not of GSC in a balanced diet (BD) (100% BD; 85% BD + 15% GSC, and 70% BD + 30% GSC). The experimental diets were offered from 29 to 85 days of age and feed intake, feed conversion and carcass yield of the chickens were evaluated at the end of the experimental period. A metabolism assay was conducted at 52 days of age to determine apparent metabolizable energy, apparent metabolizable energy corrected for retained nitrogen, and apparent metabolizability coefficients of dry matter (MCDM), crude protein (MCCP), neutral detergent fiber (MCNDF) and ether extract (MCEE). Dietary supplementation with GSC increased feed intake and worsened weight gain with increasing level of inclusion. MCDM, MCNDF and MCEE were higher for chickens receiving 85% BD + 15% GSC when compared to animals fed the control diet (100% BD), except for MCCP which was not influence by supplementation with GSC. Carcass yield, cut yield or organ weight did not differ between diets with and without GSC inclusion, while the weights of pancreas and gizzard were higher in chickens receiving 70% BD + 30% GSC compared to those receiving only BD. The on-top inclusion of GSC in the diet of free-range broiler chickens as a feed alternative is justified up to a level of 15% since it does not affect feed conversion of the animals and improves the utilization of dietary nutrients.</span> |
