Effect of Quartz porphyry(QP) on clinical chemical parameters of serum in male white java sparrow by feeding the basal diet(Control group) containing 3.0% QP(QP group) for 14 days was studied. Body weight gain, feed intake, the weight of the gizzard and the heart were not significantly different in the both groups. However, the weights of kidney and liver in the QP group were higher than in the control group. The contents of triglyceride, cholesterol, total protein, glucose, creatinine, blood urea nitrogen, uric acid and albumin, and the activities of glutamic oxaloacetic transaminase(GOT) and glutamic pyruvic transaminase(GPT) in serum were not significantly different in the both groups. The activity of alkaline phosphatase(ALP) in serum was higher in the QP group than in the control group.
