公兔摘除法去势试验

Extirpative Castration in the Buck

通过手术摘除法对11只3～4月龄雄性肉用兔进行了去势试验。结果表明,试验组增重均高于对照组,但7d、14d、21d时两组间增重差异不显著,而28d时差异极显著。同时,健康兔3月龄时去势比4月龄时更安全。提示在农区粗放饲养条件下,肉兔催肥方案可定为3月龄时去势,出售时机宜在去势后28d左右。

Extirpative emasculation was conducted in 11 male meat rabbits at the age of three to four month. The experiment showed that the body gaining after castration of the tested group was higher than that of the control group. The statistic difference of gaining between the tested group after 7 days, 14 days and 21 days of castration and that of the control one was not significant, while that difference after 28 days was statistically different. Meanwhile, the operation on three-month old bucks was saver than that on four-month ones. So the experiment indicated that, to the meat rabbit production under extensive condition, the optimal management schedule is to perform castration at the age of 3 month and marketing 28 days afterwards.
