| 摘 要： | 为了研究半胱胺对奶山羊乳腺发育的影响,选6只空怀奶山羊进行自身前后对照试验和8只妊娠奶山羊进行同胎次配对试验。结果表明,空怀奶山羊对照期乳腺的腺泡很少发育,几乎看不到乳导管,试验期乳腺有明显导管生长和少量腺泡发育;妊娠奶山羊对照组乳腺随着妊娠的进行有少量腺泡发育,腺导管有明显的生长,试验组乳腺有大量的腺泡发育,腺导管生长更明显,且有分泌物出现,血浆中与乳腺发育相关的激素水平明显升高。

| Abstract: | Six local non -pregnant dairy goats were used in a self-control design and eight pregnant dairy goats were used in a match design to study the effects of CS on mammary development in dairy goats. The results showed that the alveolar and ductal epithelial of non -pregnant dairy goats in control period were less than that in experiment period. With pregnant processing,the mammary gland of pregnant dairy goats also developed little by little,but the alveolar and ductal epithelial of pregnant dairy goats in experiment group were in abundance in comparison with the control group. As well as CS also enhanced the levels of the related hormone in plasma with mammary gland development. The above results suggested that CS promoted mammary gland development in dairy goats to some extent. |
