Effect of clinoptilolite type on performance finishing Iambs and health of liver and Kidney

In order to study the effect kinds of clinoptilolites on the chal lambs performance and health of liver and kidney ,sixteen chal lambs used in a completely randomized design. The formulated diets include : 1) control, 2) control+4% calcic clinoptiolite, 3) control + 4% potacic clinoptilolite and 4 ) control + 2% calcic and 2% potaci clinoptilolite. All diet contained 1.3 % urea on dry matter basis. Daily weight gain, feed conversion ratio, carcass weight and carcass percentage increased significantly (p> 0.05) for the diets contained clinoptiolits and this increase was higher for the diet contained calcic clinoptilolite . Liver and kidney weight and liver volume for the diet contained clinoptilolite- particularly calcic clinoptiolite - were higher. Also the number of liver cell pe 100mum2 of liver tissue was higher for lambs those received diet contain clinoptilolite especially in the case of calcic clinoptilolite. This results indicated that liver cells of sheep that consiumed diet 2 were smaller than the other. In general the result showed that 4% clinoptilolite in diet increased lamb performance and health of liver and kidney tissues, and calcic clinoptilolite worked better.
