Effects on chicks of Balanites aegyptiaca kernel saponin given by different routes of administration.

The effect of oral or parenteral administration of crude saponin extract from Balanites aegyptiaca seed kernal on Hisex-type chicks was studied. Seven-d-old chicks were given 5 mg Balanites crude saponin/kg/d im, 25 mg/kg/d ip or 250 mg/kg/day po for 3 w. When compared to controls, the body weights of dosed chicks were depressed and serum LDH and GOT activities and uric acid concentrations were significantly elevated. There were no consistent differences in serum GGT, CPK, total cholesterol and total protein between control and dosed birds. The main lesions were fatty cytoplasmic vacuolation and necrosis of hepatocytes, lymphocytic nodules, epithelial cell degeneration of the renal tubules, catarrhal enteritis and varying degrees of hemorrhage in the thigh and breast muscles. Myositis or peritonitis were observed in chicks given Balanites crude saponins im or ip, respectively.
