摘要
首次对５只成年羊驼的１０个卵巢进行了组织学观察，目的在于揭示羊驼繁殖率低的原因。结果表明：①羊驼卵巢中原始卵泡数平均为２０３３７个，左侧与右侧差异不大，但个体差异较大（范围４０９４－３８９１４）。②羊驼正常卵泡的平均直径为２．１６ｍｍ，卵母细胞核平均直径１１．８３±１．８３μ。③羊驼１０个卵巢中正常卵泡和萎缩卵泡总数为左侧８３个，右侧９２个，说明卵巢活性右侧强于左侧，其中右侧卵巢中萎缩卵泡共５９个，占同侧卵泡的６４．１％，左侧３４个，占４１．５％。④羊驼卵巢发育不良比例为２０％。其中没有发现原始卵泡，但有３－４个发育正常的卵泡，与奶牛，水牛的报导相近。但发育不良卵巢的对侧卵巢含有较多正常卵泡和萎缩卵泡，说明卵巢机能有代偿作用。本研究为羊驼繁殖提供了形态学基础资料。
Alpaca has very important economical value, But the low fertelity is effecting the reproduction. Although many reseaches were published but there has been no reseach of ovarian follicular system in Alpaca. Observation on the histology of section of 10 ovaries in alpaca, We are acquainted with: ①The numbers of primordial follicles of one ovary in adult alpaca are 17502 in mean; ② The numbers of ≥1mm follicles are 19.75 in left ovary and 22.25 in right ovary; ③The diameter of nuclei of occytes is 11.83±1.38μ Besides, We discovered 2 ovaries which is hypoplasia have no any primordial follicles but have 3 or 5 ≥1mm follicles. We discussed the methods of classify of hypoplasia and induce ovulation in Aplaca.
