Abstract
To induce copper deficiency in sheep 15 Awassi ewes were choosen from the veterenary medicine collage and randomly divided into three equal groups for the experimental period (18 weeks). the 1st group were fed on balanced concentrated diet with low level of copper (2.6) mg/day was used to feed the primary deficiency group while the 2nd group were fed on a balanced concentrated diet contained 5.2 mg/day copper in addition of the green food and the protein ratio and energy level were considered. The secondary deficiency group received an oral mixture of ammonium molybdate 100 mg with 1 g of sodium sulphate in 100 ml of water daily. Wool samples from the ewes and their lambs were collected to study the hanges in wool physical traits The experimental ewes were treated in two different ways. The primary deficiency group fed on balanced concentrated diet contained high level of copper (7.4) mg/day, while the secondary deficiency group treated orally with copper sulphate (1.5) g/ewe/day dissolved in water for (6 weeks). After two weeks of treatment the parameters raised and the ewes in the two groups looked more healthy, the wool start to grow and by the end of that period all symptoms and changes return to normal in comparison with the control group
