An experiment whose objective was to study the effect of castration age on the development and production of pigs, evaluating the weight of the piglets. Four treatments were studied: A - castration at 56 days of age; B - castration at 7 days of age; C - castration at 36 days of age; D - whole (not castrated); E - castration at 21 days of age. The Latin square design was used in order to control the variation between litters (lines) and the variation in the initial weight of the piglets (columns), with the experimental portion consisting of a piglet.
