| Summary: | Feed represents the largest cost item in production and is reflected in the productive performance of broiler chickens. The objective of this study was to evaluate the productive and economic performance of broiler chickens by partially replacing commercial balanced feed (CFB) with Gliricida sepium meal . These factors included intake (IB), weight gain (WG), feed efficiency (FE), feed conversion ratio (FC), carcass yield (CY), European efficiency productivity factor (EEPF), productivity index (PI), pigmentation (PIG), cost per kilogram of meat, net income per live chicken (NIWC), and net income per carcass chicken (NIC). A randomized design was used with three treatments: control, 15% TGs, and 30% TGs, with 12 replicates each. ANOVA was applied, adopting initial weight as a covariate. The linear and quadratic effects of replacing CFB with G. sepium were evaluated using orthogonal contrasts. A statistical difference was considered when P≤0.05. An effect of the levels of substitution of ABC by G. sepium meal (P≤0.05) was observed for CON, GP and PIG. A negative linear order effect was presented for CON, GP, CA and IP. PIG presented a positive linear order effect. A substantial decrease in feed costs per kilogram of meat produced was observed for TGs30 % compared to the other treatments. The net income per standing chicken (NIPP) and net income per chicken carcass (NIPC) presented higher values in the control group. The results demonstrate that the inclusion of G. sepium meal in the diet of broiler chickens does not exceed the productive performance obtained with ABC, however, feed costs are reduced and meat pigmentation is improved. |
