Abstract
La presente investigación se realizó en la empresa Avícola Agropecuaria Las Campiñas del Sol E.I.R.L., ubicada en el Distrito de Tarapoto, Provincia de San Martín; con el objetivo de determinar el efecto de la adición de una fitasa y de un complejo multienzimático más probióticos a dietas sobre los parámetros productivos de pollos de engorde. Se utilizaron 150 pollos de la línea Cobb 500, en un diseño completamente al azar, distribuidos aleatoriamente en tres tratamientos, T0: Dieta sin enzimas, T1: Dieta con de 100 g de Phyzyme/t de alimento y T2: Dieta con 100 g de Hidrozyme/t de alimento. Las dietas fueron isocalóricas e isoproteicas. Los incrementos de pesos totales fueron de 2,79 kg para T2, 2,74 kg para T1 y 2,7 kg para T0 (P<0,05), significando una superioridad de 3,3 y 1,5% respectivamente de los grupos con enzimas en relación al grupo control. Los consumos de alimento total fueron de 5,1 kg, 5,21 kg y 5,2 kg para T0, T1 y T2 respectivamente (P<0,05). La mejor conversión alimenticia total la obtuvo el T2 con un valor de 1,75, seguida de T1 con 1,88 y por último T0 con 1,95 (P<0,05), calculándose una mejora de 10,23% y 3,59% con relación al T0 respectivamente. Los porcentajes de mortalidad fueron de 2,0; 1,3 y 0,7% para T0, T1 y T2 respectivamente (P>0,05). Numéricamente existen diferencias, siendo T0 el que tiene mayor valor, seguido de T1 y después T2, quien tuvo el menor porcentaje de mortalidad. El T2 logró el mejor índice de eficiencia productiva con 370,7, seguido de T1 con 334 y después T0 con 309,9, calculándose una superioridad de 19,62% y 7,78% con relación al tratamiento control. La relación Beneficio/Costo calculadas fue de 1.13, 1.16 y 1,19 para los tratamientos 0, 1 y 2 respectivamente. El mayor valor fue obtenido por T2, seguido de T1 y después por T0. Se concluye que la adición de Hidrozyme (T2) a las dietas mejora significativamente los parámetros productivos de pollos de engorde.
ABSTRACT The present investigation was carried out in the company Avícola Agropecuaria Las Campiñas del Sol E.I.R.L., located in the District of Tarapoto, Province of San Martín; with the objective of determining the effect of the addition of a phytase and a multienzymatic complex plus probiotics to diets on the productive parameters of broiler chickens. A total of 150 chickens from the Cobb 500 line were randomly distributed in three treatments, T0: Diet without enzymes, T1: Diet with 100 g of Phyzyme / t of food and T2: Diet with 100 g of Hidrozyme / t of food. Diets were isocaloric and isoproteic. Total weight increments were 2.79 kg for T2, 2.74 kg for T1 and 2.7 kg for T0 (P<0,05), representing a superiority of 3.3 and 1.5% respectively groups with enzymes relative to the control group. Total feed intakes were 5.19 kg, 5.21 kg and 5.2 kg for T0, T1 and T2 respectively (P<0,05). Mortality rates of 2.0 were established; 1.3 and 0.7% for T0, T1 and T2 respectively (P> 0.05). Numerically there are differences, with T0 having the highest value, followed by T1 and then T2, which had the lowest mortality rate. The best total feed conversion was obtained by T2 with a value of 1.75, followed by T1 with 1.88 and finally by T0 with 1.95 (P<0,05), an improvement of 10.23% and 3 , 59% in relation to T0 respectively. T2 achieved the best productive efficiency index with 370.7, followed by T1 with 334 and then T0 with 309.9, with a superiority of 19.62% and 7.78% in relation to the control treatment. The Profit / Cost ratio calculated was 1.13, 1.16 and 1.19 for treatments 0, 1 and 2 respectively. The highest value was obtained by T2, followed by T1 and then by T0. It is concluded that the addition of Hidrozyme (T2) to the diets improves significantly the productive parameters of broiler chickens.
