Oestrous behaviour, ovarian follicular development, ovulation and changes in hair coat were observed in Pony mares which were unoperated, sham-ganglionectomized control or bilaterally superior cervical ganglionectomized. Surgery was performed during the winter anoestrus (1975--1976). Reproductive patterns in all groups were similar during the first breeding season (1976) after operation but in ganglionectomized mares the onset of the next breeding season (date of first ovulation in 1977), the pattern of follicular development, date of first oestrus and pattern of hair coat changes were all significantly delayed relative to those of the non-operated and sham-operated mares in 1976 and 1977 and relative to their own patterns in 1976. These results indicate that the pineal-hypothalamo-pituitary axis may regulate or moderate annual reproductive rhythms in mares.
对未做手术、做过假神经节切除对照手术或双侧颈上神经节切除的母马观察了发情行为、卵巢卵泡发育、排卵及被毛变化。手术于冬季乏情期（1975 - 1976年）进行。术后第一个繁殖季节（1976年）所有组的繁殖模式相似，但在神经节切除的母马中，下一个繁殖季节的开始（1977年首次排卵日期）、卵泡发育模式、首次发情日期及被毛变化模式相对于1976年和1977年未做手术和做过假手术的母马以及相对于它们自己在1976年的模式均显著延迟。这些结果表明松果体 - 下丘脑 - 垂体轴可能调节或缓和母马的年度繁殖节律。
