The aim of this study was to contribute to the knowledge of hormonal castration as an alternative to surgical castration in weaning pigs. It was performed at three age groups (35 to 45 days, 46 to 60 days, and 61 or older), and each age group was divided into two groups (Surgical and Hormonal Castration), with 4 pigs in each group, with 20 male piglets per group. It was determined that for the ages of 35 to 45 days and 46 to 60 days, initial weight (kg), final weight (kg), weight gain (kg), feed intake (FI) (kg), and feed conversion ratio (FCR) (kg) did not show significant differences between the groups studied (Surgical and Hormonal Castration), with a p-value >0.05. However, for ages 61 days or older, significant differences were found in final weight (kg), weight gain (kg), feed intake (kg), and feed conversion (kg), with a p-value<0.05. Only for initial weight (kg) was a p-value >0.05 found. These results demonstrate that hormonal castration is highly beneficial for the productive parameters of pig production and is also highly recommended for the health and well-being of production animals.
