A wide range of variation in concentration of manganese was found in the blood of 51 cycling ewes although no significant differences were evident (P less than 0.05) between days 4, 11 and 15 (day 0 = day of estrus) of the estrous cycle. In addition, no differences (P less than 0.05) were found in the manganese concentrations of various soft tissues of 15 ewes, killed on day 4 (five animals), day 11 (five animals) or during anestrus (five animals). The highest concentration of manganese was present in the liver, pancreas and kidney cortex, tissues which are rich in mitochondria. Among the tissues of the reproductive tract, the corpus luteum showed the highest manganese concentration and the level increased significantly (P less than 0.01) between days 4 and 11 suggesting that this trace element may be closely related to the metabolic and possible functional characteristics of this endocrine gland. Uterine horn and caruncles contained greater manganese concentrations than other components of the reproductive tract. The significance of these findings in relation to the effect of manganese intake on ewe fertility remains to be assessed.
在51只处于发情周期的母羊血液中，锰的浓度存在广泛差异，不过在发情周期的第4天、第11天和第15天（第0天=发情日）之间没有明显的显著差异（P<0.05）。此外，对15只母羊在第4天（5只）、第11天（5只）或乏情期（5只）处死时各软组织中的锰浓度进行检测，未发现差异（P<0.05）。锰浓度最高的是肝脏、胰腺和肾皮质，这些组织富含线粒体。在生殖道组织中，黄体的锰浓度最高，且在第4天和第11天之间显著升高（P<0.01），这表明这种微量元素可能与该内分泌腺的代谢及可能的功能特性密切相关。子宫角和肉阜中的锰浓度高于生殖道的其他部分。这些发现与锰摄入量对母羊繁殖力的影响之间的关系仍有待评估。
