The objective of this research was to evaluate the effect of the inclusion of B. gasipaes flour as a partial replacement of commercial balanced feed (ABC) on the productive performance of broilers. It took place in San José del Guaviare (Colombia), under a randomized design with five treatments: control, TCh2.5%, TCh10%, TCh15% and TCh20% each with ten replications. The results were ANOVA subjects, adopting the initial weight as a covariate. The linear, quadratic and cubic effects of the ABC substitution levels were evaluated by orthogonal contrasts with 5% significance. No difference was observed (P≥0.05) for GP, CA, EA, PCC, PCF, Viscera and PIG. The effect of the treatments for RCC and RCF was evidenced. There was a negative linear effect for CA, EA, PCC, PCF, RCC and RCF and a positive linear effect for PIG with the increase in the levels of B. gasipaes in the diet. The economic analysis shows an increase in the cost of food. The TCh5% presented the best INCP and INPP with respect to the other treatments. It is concluded that the inclusion of B. Gasipaes as a partial replacement for ABC does not affect the productive performance of broilers, substantially reducing production costs.Evaluamos el efecto de la inclusión de harina de B. gasipaes como reemplazo parcial del alimento balanceado comercial (ABC) sobre el desempeño productivo de pollos de engorde. Tuvo lugar en San José del Guaviare (Colombia), bajo un diseño aleatorizado con cinco tratamientos: control, TCh2,5%, TCh10%, TCh15% y TCh20% cada uno con diez réplicas. Los resultados fueron sujetos ANOVA, adoptando el peso inicial como covariable. Los efectos lineares, cuadráticos y cúbicos de los niveles de sustitución del ABC fueron evaluados por contrastes ortogonales con significancia del 5%. No fue observada diferencia (P≥0,05) para GP, CA, EA, PCC, PCF, Vísceras y PIG. Se evidenció efecto de los tratamientos para RCC y RCF. Se presentó efecto lineal negativo para CA, EA, PCC, PCF, RCC y RCF y efecto lineal positivo para PIG con el incremento de los niveles de B. gasipaes en la dieta. El análisis económico evidencia aumento en el costo de alimentación. El TCh5% presentó el mejor INCP e INPP respecto a los demás tratamientos. Se concluye que la inclusión de B. Gasipaes como reemplazo parcial del ABC no afecta el desempeño productivo de pollos de engorde reduciendo sustancialmente los costos de producción.The objective of this research was to evaluate the effect of the inclusion of B. gasipaes flour as a partial replacement of commercial balanced feed (ABC) on the productive performance of broilers.
