Clinical, and some biochemical parameters have been studied in local sheep and goat affected naturally with hypozincemia in Al-Najaf province, Iraq.

The study was conducted on 25 local Iraqi sheep and 15 goat, the age of these animals were between 1-2 year old.

No significant difference has been detected in body temperature, whereas respiratory and heart rates were significantly increased in affected animals in comparison with control.

The biochemical results revealed significant decrease in serum zinc and alkaline phosphatase level in diseased animals than in control one.
