| 摘 要： | 对70日龄“星杂579”母鸡,以10lx的照度和14L:10D的光照周期补加光照,至270日龄时,摘取甲状腺制做光镜、电镜样品进行观察。结果:补加光照的实验组与自然光照的对照组鸡的开产率、产蛋量和甲状腺滤泡上皮的厚度差异非常显著(P<0.01),而体重和甲状腺腺体的重量、大小及滤泡腔内径没有显著差异(P>0.05)。实验组与对照组比较,其甲状腺滤泡上皮细胞(不论柱状或扁平上皮细胞)及滤泡腔内胶质均呈现功能活动旺盛的结构相。

| Abstract: | Seventy-day-old Starcross 579 hens were housed under the light of 10 lx intensity and 14 L: 10 D cycle. At the age of 270 days, their thyroid glands were dissected and observed with light microscopy and electron microscopy. As far as the ratio of layers at the start of egg-laying, yield of egg-laying and the thickness of the follicular epithelia are concerned, there was significant difference between the hens of group supplied with light and control group but no difference in the body weight, and weight, size and follicle diameter of thyroid gland. ompared with the control group, both the follicular cell and the colloid mass revealed active structural features. |
