Abstract
The objective of the research was to improve the productive parameters in Creole chickens through gonadectomy in the Tungurahua Province, Ecuador. A completely randomized design with three treatments and a control was used, the results were subjected to an analysis of variance (ADEVA) for the separation of means and the Tukey test of 5%, the factors under study were: T1 (8), T2 (9) and T3 (10), castrated weeks of age, and uncastrated chickens (20 birds / treatment), with a productive period after castration of 12 weeks. Weight gain 12 weeks after castration was higher in chickens operated on at 8 weeks of age, (343.6 g bird / week, p <0.05). The lowest feed consumption was in week 3 post castration (p <0.05). Roosters castrated at 8 and 9 weeks had better feed con-version (6.33 and 6.53, respectively) (p <0.05). Carcass yield was higher in castrated roosters compared to the uncastrated control group (p <0.01). The mortality. It was better in T1 (8 weeks old) with 0%. For this reason, the application of the surgical technique performed at of age is the most recommended.
