The authors made the growth and feed conversion performances comparison between groups of Burdizro rams, castrated _rams at an age of 6.5 months and partially castrated rams at 2 months by the short scrotum technique. After a 384 days experiment, the average weights are respectively 49.24 kg, 39.44 kg and 47.15 kg. The daily weight gains for the 244 days period following total castration are respectively 110 g, 75 g and 102 g (0.05 > p > 0.01). Full castration has consequently a depressive action on the weight gain. No significative difference is observed between entire rams and partially castrated ones. Heart girth and height at withers were not significatively influenced by these treatments. Consumption index and voluntary feed intake of the fully castrated rams are above those of the 2 other groups, which means a lower feed conversion and a higher cost of the weight gain.
