Description
During the summer of 1995, clinical chronic bovine fluorosis was identified in Fowa villages (Kafr El-Sheikh Governorate) where many brick kilns were established. 26 cows (5-9 years) of native breed were investigated. 16 animals were collected from different areas around the kilns, another 10 animals (control group) were taken from areas away from the brick kilns. The affected cows showed reduced appetite, general loss of body condition, lameness and dental lesions in the form of staining, mottling and blackish discoloration especially the incisors teeth. Serum calcium and total protein were significantly decreased, whereas serum alkaline phosphatase activity, fluoride content, urea, and creatinine were significantly increased, compared with control animals. Haematological examination of affected cows showed significant decreases in haemoglobin and haematocrit. It was suspected that fluorosis was caused by environmental pollution with fluorine-bearing smoke arising from the large number of brick kilns
