摘要
120羽35日龄迪卡商品代蛋用雏鸡随机分为高钙组,高蛋白组和对照组。各组分别饲喂高钙(含钙3.9％)、高蛋白(含粗蛋白44.0％)和拿价(含钙0.8％,粗蛋白8.2％)饲料。至试验第25d时,各组剖检5只鸡,并作肾脏的光镜和电镜观察。结果表明:高钙、高蛋白饲料能引发尿酸盐沉积。但高蛋白组眼观病变不明显,肾脏的光镜、电镜病变与高钙组相似,但损伤程度较轻。怍者认为,高钙、高蛋白引起肾脏损害是鸡尿酸盐沉积的重要原因。
120 35 - day - old chicks were divided into high-calcium, high - protein and control groups at random. They were fed high -calcium (Ca : 3. 9%), high - protein (C. P:44. 0%)and basic diet (Ca:0. 8%, C. P:18. 2%) respectively. 5 chickens in each group were dissected, and kidney was sampled and observed by optical microscope and electrical microscope. Results showed that uric acid salt deposit in chickens was caused by high - calcium and high - protein diet. The Author considers that the main cause of uric acid salt is renal damage caused by high-calcium and high -protein diet.
