摘　　要：在自由饮水条件下给未阉割的雄性绵羊羔羊饲喂高磷和高镁组合日粮。经过1个月的饲喂后,对照组表现正常,并无尿石症相关症状出现;试验组在饲喂后期逐渐表现出尿结石的相关症状,血液中镁和磷的浓度也出现显著升高,尿液中尿沉渣出现增多且晶体形态与鸟粪石晶型相同。对出现尿闭的羔羊解剖后检出了尿结石,经测定其成分以磷和镁为主。试验结果表明,单纯饲喂添加高磷和高镁组合日粮可以诱导未阉割的雄性绵羊羔羊产生尿结石,且尿结石的形成与日粮中磷和镁元素的含量过高相关。The rams which haven＇t been castrated were fed with mixture dietary of high dosage of phosphate and magnesium contents under free water intake condition. After one month of feeding, the control group appeared normal and occurred irrelevant urinary calculi symptoms, whereas high serum magnesium and phosphorous levels were present in the experimental group. Crystallographic analysis of urinary sediments shows same morphology as guanite. Urinary calculi that consist of phosphate and magnesium were observed by anatomic study of anuria rams. It is revealed that mixture dietary of high dosage of phosphate and magnesium contents is the potential cause of ram urinary calculi, stone formation is related to the higher phosphate and magnesium contents in dietary.
