The growth of wool is closely related to copper. If you do not pay attention to supplements, it will directly affect the quality of wool. The lack of copper in the forage will cause anemia in the sheep and will reduce the degree of bending of the wool and reduce the cystine content of the wool horn protein. The wool will not only have poor luster but also will lack black pigment. After weathering forage in winter, the loss of copper in forage grass is serious, and sheep are more susceptible to copper deficiency. In order to ensure the health of the sheep and obtain higher quality wool, 2ml of 1/1000th copper sulfate solution may be added to the sheep's diet for 5 days. Feed for 5 days every 20 days until the spring green feed is sufficient. This can not only improve the quality of wool, but also can prevent the sheep from lacking copper anemia and ensure that the sheep grow normally.
