How to prevent lamb leukomyopathy? Rapid treatment of white myopathy in sheep

Lamb leukomyopathy is also known as muscular dystrophy. Diseases characterized by degeneration and necrosis of skeletal muscle (Figure 6-1), myocardium, and liver tissues due to deficiency or insufficiency of the trace elements selenium and vitamin E in the diet. The disease can occur in both lambs and baby goats.

Figure 6-1 Prevention of skeletal muscle in lamb leukomyosis (1).

For selenium-deficient areas, newborn lambs every year should be injected subcutaneously or intramuscularly with sodium selenite solution about 20 days after birth, and then injected with milliliters at intervals of about 20 days. The injection start date should not exceed 25 days of age at the latest. The next injection of sodium selenite into the skin of pregnant ewes, at a dose of 4 6 mg, can prevent neonatal lamb leukomyopathy.

2）**。For diseased lambs, each lamb should be immediately injected subcutaneously or intramuscularly with sodium selenite solution, subcutaneously injected into the neck, and injected again every 20 days, and vitamin E should be injected at the same time, the effect is better.

Leukomyosis is an acute or subacute metabolic disease of lambs, characterized clinically by dyskinesia and circulatory collapse, and pathologically by degeneration and necrosis of skeletal and myocardial muscles.

1. Key points of diagnosis can be diagnosed according to the history of local selenium deficiency, feed analysis, clinical manifestations and special lesions of pathological autopsy, as well as the good effect of selenium preparations. In addition, according to the experience of the herdsmen, the lamb is picked up and thrown gently, and the strong lamb immediately runs away, but the sick sheep stop for a while.

This method can be used as a basis for early diagnosis.

1. **: Caused by lack or insufficiency of selenium and vitamin E in forage and feed.

2. Most of the patients with severe symptoms do not show symptoms and suddenly fall to the ground and die. Cardiomyomyosis may show rapid heartbeat, irregular rhythms, intermittent and diastolic murmurs, and tachypnea or dyspnea. Musculoskeletal leukomyosis lamb movement disorder, manifested as reluctance to move, like to lie down, unsteady gait when walking, broken walking, difficulty in standing up in severe cases, and stiff muscles when standing.

Some sick lambs have diarrhea.

2. Prevention and control measures.

1. Prevention In areas lacking selenium, it is necessary to pay attention to adding selenium to the feed of female (pregnant) sheep and lambs.

2. **In selenium-deficient areas, lambs can be injected with 1 ml of sodium selenite injection about 10 days after birth, and after an interval of 20 days, they can be injected again with ml. For ewes in late pregnancy, a subcutaneous injection of sodium selenite at a dosage of 4 6 mg can also prevent the development of white myopathy in lambs. If the disease has already occurred in lambs, sodium selenite should be used immediately**, and the dosage per sheep is milliliters.

Vitamin E10 15 mg can also be injected subcutaneously or intramuscularly once a day several times.

Rapid ** methods for sheep leukomyopathy: (1) iron and blood supplementation (injection of iron and blood Wangyuan) (2) removal of worms on the liver (injection of liver mite net) large groups of three days effective.

If the disease is severe and there is a secondary infection, it can be carried out simultaneously with anti-inflammatory sterilization, and the disease can be prevented in advance. Reduce your losses!
