中草药复方制剂对公猪精液品质和生殖激素的影响

Effects of Chinese Herb Feed Additives on Sperm Quality andReproductive Hormone of Boars

为了研究中草药复方制剂对公猪精液品质和生殖激素的影响,对27头精液品质相近的成年大约克种公猪饲喂不同剂量的中草药复方制剂,测定精液指标和血清生殖激素水平。结果表明:与对照组相比,2%低剂量组(试验Ⅰ组)的采精量、采精持续时间、精子密度,血清中促卵泡刺激素(FSH)、促黄体生成素(LH)和睾酮(T)含量差异显著(P<0.05);与对照组相比,3%高剂量组(试验Ⅱ组)的采精持续时间、精子活力和血液中LH、T含量显著提高,采精量和血液中FSH含量差异极显著(P<0.01);高、低剂量组的精子畸形率与对照组相比均有所降低。说明日粮中添加一定剂量中草药复方制剂可显著提高种公猪的精液品质,促进生殖激素的分泌。

In order to research the effects of Chinese herb feed additives on the sperm quality and repro- ductive hormone of boars, 27 Large White boars with similar quality of semen were fed different dose of Chinese herb feed additives and their semen index and level of reproductive hormone in serum were evalu- ated. The experiment results showed that compared with control group, the length of semen, collection time, fresh semen volume, sperm density, and the content of FSH, LH and T in the serum of pigs in the 2% low dose group were improved significantly （ P 〈 0.05）, the serum of pigs in the 3 % high dose group had significant difference compared with the control group; fresh semen volume and the content of FSH in the serum of pigs in the high dose group had very significant difference compared with the control group（ P 〈 0.01 ）. And abnormal sperm rate of pigs in low dose group and high dose group compared with the control group were reduced. In conclution, Chinese herb feed additives was very important for boars to keep a good sperm quality.
