Las políticas de bienestar animal se expandieron para garantizar las necesidades de los animales
frente a la demanda del mercado consumidor. La castración es cuestionable desde el punto de
vista de bienestar animal en la producción animal. Este estudio tuvo como objetivo investigar
el efecto de la anestesia local antes de la orquiectomia en la performance de lechones previo al
desmame, mediante evaluación de la ganancia de peso. Los animales con edad entre tres y siete
días fueron divididos en dos tratamientos: orquiectomia sin anestesia local (SURG; n = 52) y
con anestesia intratesticular (SURG+LA; n = 52). Los animales fueron pesados antes (W0), a
los siete (W1) y 14 días (W2) luego de la orquiectomia, siendo el último pesaje concomitante
al desmame. El análisis estadístico fue realizado a través de análisis de variancia (ANOVA)
seguida por test de Student-Newman-Keuls para evaluar las diferencias entre los grupos. No
fueron encontradas diferencias entre el peso o ganancia de peso (3.57 ± 0.60 kg y 3,74 ± 0.71
kg, respectivamente; p = 0.17) al momento del desmame. El uso de la anestesia local no fue
importante para la ganancia de peso de los animales castrados en las condiciones
experimentales propuestas, sin embargo considerándose que el período experimental fue
relativamente corto el estudio necesita una evaluación que alcance otras etapas del ciclo
productivo.
