Resumen
El objetivo del presente estudio preliminar fue evaluar el efecto de un aditivo comercial a base de compuestos bioactivos sobre los parámetros productivos y la salud intestinal en pollos parrilleros. Se utilizaron 100 pollos parrilleros (Cobb) de 1 día de edad, se pesaron y se seleccionaron en 2 grupos de tratamiento con 10 réplicas/ 5 aves por replica. Durante el período experimental (48 días), los pollos recibieron una dieta iniciadora y una terminadora. Tratamiento (T) T1: dieta basal (DB - Control); T2: DB + aditivo comercial (100g/T). Se determinaron parámetros productivos, histomorfométricos intestinales, concentración de ácidos grasos volátiles (AGV) y recuento de bacterias lácticas y entéricas. La GPVS mostró diferencias significativas con la adición del aditivo comercial comparado con el T1 en la semana 21 (p <0,05); cuando se adicionó el aditivo comercial los parámetros productivos mostraron una tendencia positiva obteniendo un mayor índice de productividad; los niveles de AGV y el recuento de bacterias lácticas fueron mayores en T2 (p<0,05). En conclusión, la suplementación con el aditivo comercial mostró una tendencia creciente en los parámetros productivos, moduló positivamente la salud intestinal en pollos parrilleros, al menos a la dosis y con el número de animales utilizados, constituyendo una posible alternativa al reemplazo de antibióticos como promotores del crecimiento. En base a estos resultados se propone realizar un ensayo in vivo con un número mayor de animales y comparar la eficiencia con la inclusión de antibiótico como promotores del crecimiento.
This preliminary study aimed to evaluate the effect of a commercial additive based on bioactive compounds on the productive parameters and intestinal health in broiler chickens. A total of 100 oneday-old Cobb birds were used, and at 7 days were weighed and randomly selected into 2 treatment groups with 10 replicates/5 birds per replicate. During the experimental period (48 days), the broiler chickens received the starter and finisher diet. Treatment (T) T1: basal diet (BD - Control); T2: BD + commercial additive (100g/T). The histomorphometric parameters of the intestine, along with volatile fatty acids concentration and counts of lactic and enteric bacteria, were determined. At week 21, the addition of commercial additive resulted in significant differences in weekly live weight gain compared to T1 (p <0.05). The addition of commercial additive showed a positive trend in productive parameters and obtained a higher productivity index. The levels of volatile fatty acids and the count of lactic bacteria were found to be higher in T2 as compared to the control (p < 0.05). In conclusion, supplementation with the commercial additive showed an increasing trend in productive parameters, positively modulated intestinal health in broiler chickens, at least at the dose and with the number of animals used, constituting a possible alternative to replacing antibiotics as promoters of growth. Based on these results, it is proposed to carry out an in vivo trial with a higher number of animals and compare the efficiency with the inclusion of antibiotics as growth promoters.
