| Abstract: | male Rex rabbits were used to study effects of castration at different ages on growth rate,slaughtering performance,meat and fur qualities The results showed that:castration was carried on at 3-3 5 mon,2 5-3 mon and 2-2 5 mon,after a raising period of three months,growth rate increased 18 34%(P<0 05),24.78%(P<0.01) and 17.56%(P<0.05) respectively compared with the corresponding controls.The castrated at 3-3 5 mon had a higher(21 72%) feed gain ratio than that of the control,but that of the other two groups decreased 34 42% and 29 54% respectively.Castration had insignificant effects on dressing percentage,muscle and fur qualities. |
