The importance of the sheep in Marocco was shown with help of statistical data. As there exist very few scientific work on sheep reproduction in this country, we began to work on local breeds with the race d'Man. The breed is asaisonal and is able to lamb 2 times within 13 months, with mostly 2 or more youngs (1,8 lambs per partum). The delay of gestation was found with 150 days, the duration of a cycle 17 days. The libido shown by the rams is violent. They easily accepted an other male as phantome for the collection of sperm with the easily accepted artificial vagina. The gonads are ovoid formed and are early developed. Remarkable is the tail of the epididymis which is covered in a pocketlike formed structure of the distal scrotum. Its volume is remarkable. Concerning the characteristics of the sperm there is no difference with other breeds. Therefore the conclusion seems reasonable that this apparent development of the epididmymis tail is an organ for thermoregulation for the sperm as the breeds origin are the oasis of the Sahara. The early onset of puberty as well as the violent sexual interest and the high rate of reproduction and asaisonal behavior could be a reference to a "primitive breed".
借助统计数据表明了绵羊在摩洛哥的重要性。由于该国关于绵羊繁殖的科学研究非常少，我们开始对当地的曼恩品种进行研究。该品种具有季节性，能够在13个月内产羔2次，每次大多产2只或更多羔羊（每次产羔1.8只）。妊娠期为150天，周期时长为17天。公羊表现出强烈的性欲。它们很容易接受另一只公羊作为采精时的假台畜，且能轻松接受人工阴道。性腺呈卵形且发育较早。值得注意的是附睾尾部，它被阴囊远端的袋状结构所覆盖。其体积很大。关于精子的特征，与其他品种没有差异。因此，鉴于该品种起源于撒哈拉沙漠的绿洲，附睾尾部这种明显的发育似乎是一种为精子进行温度调节的器官，这一结论似乎是合理的。青春期早熟、强烈的性兴趣、高繁殖率以及季节性行为可能表明这是一个“原始品种”。
