研究了褪黑激素对绒山羊皮肤脱碘酶（MD）活性及绒纤维生长的调控作用。选用18只半同胞内蒙古绒山羊，随机分为两组（n = 9只/组）。一组皮下植入褪黑激素（2毫克/公斤体重），在三个2个月的时间间隔，而另一组作为对照。所有山羊均在自然光周期条件下饲养，并在天然牧场上放牧。血浆褪黑素浓度差异有统计学意义（p0.05）。皮肤单脱碘酶11型（MIDII）活性从夏至至11月逐渐升高。在7月和8月，M组的MDII活性较高（p
The roles of melatonin in the control of deiodinase (MD) activity in cashmere goat skin and associated cashmere fibre growth were investigated. Eighteen half-sib Chinese Inner Mongolia cashmere wethers were allocated randomly to two groups (n = 9/group). One group was implanted subcutaneously with melatonin (2 mg/kg BW) at three 2-monthly intervals while the other group served as a control. All goats were maintained under natural photoperiodic conditions and were grazed on natural pasture. The plasma melatonin concentration showed a significant difference (p0.05). The monodeiodinase type 11 (MIDII) activity in skin tended to increase gradually from the summer solstice to November. During July and August, the activity of MDII for the M group was higher (p
