Abstract
In order to analyze the effects of castration on growth performance, cortis ol, thyroxine and testosterone assays were performed on three randomized gr oups of grasscutters (Thryonomys swinderianus, Temminck, 1827). ten complet e females, ten complete males and ten surgically castrated males over 4 mon ths of age. The growth rate of the castrated animals was lower than that of the intact males, but higher than that of the females. The weight gain was positively correlated with blood thyroxine concentration and negatively co rrelated with blood cortisol concentration. ((C) Elsevier / Inra).
