摘要：

为研究6月龄去势对延边黄牛生长性能及血液激素的影响，试验选用20头6月龄体重、体况相近的延边黄牛，随机分成2组，每组10头，试验组黄牛6月龄去势，对照组不去势，试验期12个月。试验期间在试验牛6、8、10、12、14、16及18月龄的当月12号称重并测量体尺，每次称重前一天早上空腹经颈静脉采血，检测血清睾酮和生长激素的含量。结果显示，试验期间试验组黄牛去势后体重均低于对照组，其中8月龄时差异显著（P < 0.05）；试验组延边黄牛体高、胸围、体斜长均低于对照组，但差异均不显著（P > 0.05），6~8月龄时，试验组去势黄牛体高的增长显著低于对照组（P < 0.05），12~14月龄时，试验组显著高于对照组（P < 0.05），其他月龄间两组差异不显著（P > 0.05）。试验组黄牛去势后血清睾酮水平极显著或显著低于对照组（P < 0.01；P < 0.05），试验组黄牛血液生长激素水平低于对照组，其中8月龄时差异显著（P < 0.05）。综上所述，6月龄去势能够降低延边黄牛体重的增长，但对体尺影响不大，且能降低延边黄牛血清睾酮及生长激素水平。

Abstract:

In order to study the effect of castration at 6 months old on growth performance and blood hormones of Yanbian cattle at 6 to 18 months of age, 20 Yanbian cattle that were 6 months old with similar body weight and body size indexes were randomly divided into 2 groups. The cattle in test group was castrated at 6 months old,and that in control group did not do any treatment,and the test period was 12 months. At the 12th of 6,8,10,12,14,16 and 18 months old,the body weight and body size indexes were measured,and the fasting blood sample were collected the day before 12th to detect the serum testosterone and growth hormone. The results showed that the body weight of the test group was lower than that of the control group,and there was a significant difference at 8 months old (P < 0.05). The body height,body length and chest circumference of the test group were lower than that of control group(P>0.05),and the increase of body height of test group was significantly lower than that of control group at the age of 6 to 8 months old (P < 0.05),while that was significant higher than control group at 12 to 14 months old (P < 0.05). The level of serum testosterone in the test group was extremely significantly or significantly lower than that in the control group after castration (P < 0.01;P < 0.05), and the level of serum growth hormone in Yanbian cattle was significantly lower than that in the control group at 8 months old (P < 0.05). In summary,the castration at 6 months old could reduce the growth of body weight,serum testosterone and growth hormone levels of Yanbian cattle,but had little effect on the body size.

Key words: Yanbian cattle; castration; growth performance; testosterone; growth hormone
