Sheep need dozens of trace elements to maintain growth and health, some of which can be synthesized in vivo, some of which can be taken from forage, and some of which must be supplemented with fine supplements. The following are five trace elements that sheep are relatively easy to lack.
Sheep need dozens of trace elements to maintain growth and health, some of which can be synthesized in vivo, some of which can be taken from forage, and some of which must be supplemented with fine supplements. The following are five trace elements that sheep are relatively easy to lack.
1. selenium
It is a component of glutathione peroxidase in cells all over the animal body, which can prevent the accumulation of lipid peroxides in the body and protect cell membranes and mitochondria. It is an essential element for the conversion of methionine into cysteine. Together with vitamin E, it plays an antioxidant role in animals, promotes the absorption and storage of vitamin E, participates in amino acid metabolism in the body, and plays an important role in protecting the body's stable immune function, and can protect the myocardium, maintain the normal growth and fertility of sheep. Selenium deficiency can cause liver necrosis, myocardial degeneration and pancreatic atrophy, so that young sheep appear nutritional muscle atrophy, white myopathy, lamb is the most common and most serious. For adult sheep, it is characterized by reproductive dysfunction, reduced fecundity, and severe weight loss. There are large areas of selenium deficiency in Northeast China, Inner Mongolia, Shandong and Hebei provinces, and selenium supplementation should be paid attention.
2. cobalt
Cobalt deficiency can reduce the activity of rumen bacteria, inhibit the microbial synthesis of B vitamins and vitamin K, reduce the digestion and absorption of vitamin A, D and E in feed, and affect the reproductive performance of ewes. In the absence of cobalt oxide or cobalt salts should be added to the diet of sheep at a dose of 0.1 mg per animal per day.
3. copper
Copper is the main hematopoietic element. Copper deficiency can cause blocked iron absorption and anemia, manifested by growth disorders, bone deformities and hair color. Newborn lambs due to spinal cord and brain lesions, movement disorders caused by rocking disease in some salinized reed meadow areas in China, there have been typical lamb copper deficiency; Hu sheep due to copper deficiency caused by rumen fiber nodules. Copper deficiency in order to supplement the best effect of copper sulfate, because the sheep's liver cells have a strong affinity for copper, easy to accumulate, must pay attention to prevent steel poisoning.
Zinc 4.
Zinc is a component of many enzymes, proteins and ribose in sheep. The most obvious symptoms of deficiency are thickening of epidermal cells, keratinization, loss of appetite, growth retardation and decreased fecundity, and easy shedding of wool. The "big cloth" disease of sheep occurred in some areas of Inner Mongolia due to zinc deficiency, while the ram showed a decrease in ejaculation volume and a decrease in semen quality. Zinc can be supplemented by subcutaneous injection of long-acting zinc or as a compound additive.
5. of manganese and iodine
Sheep manganese deficiency, ewe estrus is not obvious, and easy to abortion; ram sperm production abnormalities. Iodine deficiency will reduce the basic metabolism of sheep, dry skin, hair brittle and easy to fall off, weight loss, ram semen quality is not good. Iodine deficiency with potassium iodide, calcium iodide or iodized salt to be fed.
