The objective of the present study was to determine the effects of dietary natural clinoptilolite on serum contents, health status and feeding performance of rats. Adult male Sprague-Dawley rats (n=24) were randomly divided into four groups with three replicates including a control group (without zeolite) and three doses of natural zeolite (2, 4 & 6%) in the diets. All rats were fed the above concentrates during the whole experimental period for 56 days. Blood samples were collected from each animal at the end of the experiment. Dietary clinoptilolite increased in serum albumin, triglyceride and VLDL levels (P less than 0.05). However, the differences among treatment groups were not significant for serum minerals (Ca, P, Mg, K, Na, Cl, Fe), urea, Fe binding, LDL, alkaline phosphatase, glucose, uric acid, total Fe, total protein, globulin, cholesterol, HDL cholesterol, creatinin; metabolizable energy and crude protein consumption for 1g live weight gain of rats (P greater than 0.05). The results showed that the supplementation of clinoptilolite did not have positive effect on serum concentrations of the investigated parameters apart from albumin, triglyceride and VLDL, but they had no negative effect on the health status of animals.
