Evaluación del comportamiento productivo de pollos broiler utilizando un promotor de crecimiento Promyze New, en dietas 0, 2 y 4% menos de la relación energía/proteína, en el cantón Morona.

Abstract

This research was carried out in the parish of San Isidro located 12 km from the city of Macas in the Morona Canton, province of Morona Santiago; whose purpose was to evaluate the productive parameters of Broiler chickens (Cobb 500) subjected to a 2% and 4% decrease in the energy/protein ratio plus the addition of a growth promoter. The research was carried out with a population of 150 one-day-old male Broiler chicks, which were distributed in three treatments with five replicates each, and each replicate consisted of 10 chicks, where T0 (0% decrease in the energy/protein ratio) was considered, T1 (2% decrease in the energy/protein ratio) and T2 (4% decrease in the energy/protein ratio), the growth promoter was supplied as suggested by the commercial house, which was 5 g/2 kg of feed per day, and they were exposed to similar environmental and management conditions. A Completely Randomized Design (CRD) was used and for the statistical analysis the experimental results were subjected to an analysis of variance (ADEVA) and separation of means according to Tukey with a significance level (p<0.05); with respect to the results there were no significant differences in any of the variables studied, concluding that the decrease of 2% and 4% of the energy/protein ratio plus the addition of a growth promoter had no effect on the variables studied. Therefore, it is recommended to carry out similar research studies during other months in order to define how the productive parameters obtained during other times of the year vary.
