What trace elements are easy to lack in raising sheep

Selenium selenium is distributed in the cells of the animal's body. It is a component of glutathione peroxidase, which can prevent the accumulation of lipid peroxides in the body and protect the cell membrane and mitochondria; it is the result of the conversion of methionine to cysteine. An essential element that cooperates with vitamin E to act as an antioxidant in the animal body. It promotes the absorption and storage of vitamin E. It also participates in amino acid metabolism in the body. It plays an important role in protecting the body's stable immune function, and can protect the heart muscle and maintain The normal growth and fertility of sheep. Lack of selenium can cause liver necrosis, myocardial degeneration and pancreatic atrophy, causing nutritional muscle atrophy and white muscle disease in young sheep. Lambs are the most common and most serious. For adult sheep, it is manifested as reproductive disorders, reduced fecundity, and severe weight loss, so attention should be paid to selenium supplementation.


Cobalt Cobalt deficiency will lead to reduced rumen bacterial activity, inhibit the microbial synthesis of B vitamins and vitamin K, reduce the digestion and absorption of vitamins A, D and E in the feed, and affect the reproductive performance of ewes. In the case of deficiency, cobalt oxide or cobalt salt should be added to the sheep's diet at a dose of 0.1 mg per animal per day.

Copper Copper is the main hematopoietic element. Copper deficiency can cause obstruction of iron absorption and anemia, manifested by growth failure, bone deformities, and lightening of coat color. In some areas of salinized reed meadows in my country, typical lamb copper deficiency has occurred. Newborn lambs have spinal cord and brain lesions caused by copper deficiency, and kinesthesia caused by movement disorders. Rumen fibrous nodules have occurred in Hu sheep due to copper deficiency. ball. When copper is lacking, the effect of supplementing copper sulfate is the best. Because sheep's liver cells have a strong affinity for copper, it is easy to accumulate, so care must be taken to prevent copper poisoning.

Zinc Zinc is a component of many enzymes, proteins and ribose in sheep. The most obvious symptoms of deficiency are thickened epidermal cells, keratinization, loss of appetite, growth retardation and decreased fertility, and wool is easy to fall off. In some areas of my country's Inner Mongolia, the "big blouse" disease has occurred in sheep due to zinc deficiency, while the ejaculate volume of rams has decreased, and the quality of semen has decreased. Zinc can be supplemented by subcutaneous injection of long-acting zinc or feeding as a compound additive.

Manganese When a sheep lacks manganese, the ewes are not in estrus and are prone to miscarriage; the rams produce abnormal sperm.

Iodine Iodine deficiency will reduce the sheep's basic metabolism, dry skin, brittle hair, weight loss, poor quality of ram semen, etc. When iodine is deficient, use potassium iodide, calcium iodide or iodized table salt to feed it.
