Abstract
El presente estudio tuvo por objetivo evaluar el efecto de la enramicina sobre el rendimiento de carcasa, pechuga, inmunocompetencia e integridad intestinal en pollos de engorde. Para el experimento se utilizaron 800 pollos BB machos de 1 día de edad que fueron distribuidos al azar entre 4 tratamientos con 8 repeticiones cada uno, donde los tratamientos utilizados fueron: T1: dieta basal, T2: T1 + Bacitracina Metileno Disalicilato (BMD) 11% (1kg/TM (110ppm) para el inicio y 0.5kg/TM (55 ppm) para crecimiento y acabado), T3 :T1 + Enramicina 8% (Producto A, dosis 125g/tn (10 ppm)) y T4:T1 + Enramicina 8% (Producto B, dosis 125g/TM (10 ppm)). Las dietas fueron suministradas ad libitum, las cuales fueron divididas en tres etapas: AABB Inicio (1 – 21 días), AABB Crecimiento (22 – 35 días) y AABB Acabado (36 – 42 días). Las muestras para evaluar los rendimientos de carcasa, pechuga e inmunocompetencia fueron tomadas a los 42 días y para la evaluación de la integridad intestinal se tomó muestras a los 35 y 42 días. Los datos obtenidos fueron sometidos a un análisis de varianza utilizando un Diseño Completamente al Azar y la comparación de medias se realizó mediante la Prueba de Duncan. Los resultados mostraron que el uso enramicina no afectaron (P ˃ 0.05) el rendimiento de carcasa, rendimiento de pechuga e inmunocompetencia a los 42 días. El uso de enramicina influyó (P ˂ 0.05) sobre el score de salud intestinal. Los parámetros de integridad intestinal: peso de ciego, peso de intestino y longitud intestinal no se vieron afectados (P ˃ 0.05) por el uso de enramicina a los 35 y 42 días. Se concluye que el uso de enramicina no afecta el rendimiento de carcasa, rendimiento de pechuga, inmunocompetencia y parámetros de integridad intestinal como peso de ciego, peso de intestino y longitud intestinal.
The objective of the present study was to evaluate the effect of enramycin on carcass and breast yield, immunocompetence and intestinal integrity in broilers. In this experiment, 800 1-day-old male BB chickens were used, which were randomly distributed among 4 treatments with 8 repetitions each, the treatments used were: T1: basal diet, T2: T1 + Bacitracin Methylene Disalicylato (BMD)11% (1kg/MT (110 ppm) for the beginning and 0.5kg/tn (55 ppm) for growth and finishing), T3: T1 + Enramycin 8% (Product A, dose 125g/MT (10 ppm)) and T4: T1 + Enramycin 8% (Product B, dose 125g/MT (10 ppm)). The diets were supplied ad libitum, which were divided into three stages: AABB Start (1 – 21 days), AABB Growth (22 – 35 days) and AABB Finish (36 – 42 days). The samples to evaluate the yields of carcass, breast and immunocompetence were taken at 42 days and the samples for the evaluation of the intestinal integrity were taken at 35 and 42 days. Registered data were submitted to analysis of variance using a Completely Randomized Design and for mean comparison Duncan Test was employed. The results showed that the use of enramycin did not affect (P ˃ 0.05) carcass yield, breast yield and immunocompetence at 42 days. The use of enramycin influenced (P ˂ 0.05) the intestinal health score. Intestinal integrity parameters: cecum weight, intestine weight and intestinal length were not affected (P ˃ 0.05) by the use of enramycin at 35 and 42 days. In conclusion the use of enramycin did not affect carcass yield, breast yield, immunocompetence and intestinal parameters such as cecum weight, intestine weight and intestinal length.
