The serum levels of calcium, phosphorus, magnesium, copper, zinc and iron and of nitric oxide, retinol, and β-carotene were determined in Sakiz ewes that had experienced an abortion and in healthy controls. Ten healthy and 25 aborted Sakiz sheep were selected from Afyon zone in western Turkey. Their ages ranged between 2 and 4 years weighing between 40 and 60 kg at the time of experiment. All of the abortions occurred in October. The concentrations of retinol, β-carotene, phosphorus, and zinc were significantly lower and those of calcium and nitric oxide were increased in aborted ewes relative to healthy controls. The serum levels of iron, copper, and magnesium were not significantly different among the two groups. In conclusion, abortion is an important problem in commercially important species of ruminants in many regions in the tropics including of western Turkey. Deficiencies of retinol, β-carotene, phosphorus and zinc, and the increase of calcium and nitric oxide concentration may play an important role in the etiology of abortion in ewes. Prophylactic measures such as vitamin and mineral supplementation may be of help to prevent or reduce the incidence of abortion in sheep.
对经历过流产的萨基兹母羊和健康对照组母羊的血清钙、磷、镁、铜、锌、铁以及一氧化氮、视黄醇和β-胡萝卜素水平进行了测定。从土耳其西部阿菲永地区挑选了10只健康的和25只流产的萨基兹羊。它们的年龄在2至4岁之间，实验时体重在40至60公斤之间。所有流产均发生在10月。与健康对照组相比，流产母羊的视黄醇、β-胡萝卜素、磷和锌浓度显著降低，而钙和一氧化氮浓度升高。两组之间铁、铜和镁的血清水平无显著差异。总之，在包括土耳其西部在内的热带地区许多商业化养殖的反刍动物品种中，流产是一个重要问题。视黄醇、β-胡萝卜素、磷和锌的缺乏以及钙和一氧化氮浓度的升高可能在母羊流产病因中起重要作用。补充维生素和矿物质等预防措施可能有助于预防或降低绵羊流产的发生率。
