Causes of anemia in sheep
First, nutrition is not comprehensive. The forages for raising sheep in agricultural areas are mostly crop stalks, which are relatively simple, which can easily cause the undernutrition or imbalance of the sheep, which makes the sheep gradually starve and lose weight, and even anemia occurs. This factor causes the sheep to suffer from anemia often.
The second is anemia caused by acute or chronic bleeding. Such as trauma, surgery and digestive tract, birth canal bleeding.
Third, due to the single feed, lack of trace elements such as copper, iron, cobalt, etc., affecting the normal function of hematopoietic function and causing anemia.
The fourth is caused by parasites. In vitro and in vivo parasites of sheep, especially hookworms, toadstools, and flukes of the liver, often cause anemia.
The fifth is secondary to various diseases, which are the main causes of anemia in sheep, such as some infectious diseases and chronic diseases.
Sixth, the sheep house has a bad environment, a sudden change in climate, rainy and humid, long-distance transportation and other stress causes cause diseases, secondary to anemia.
Symptoms of sheep anemia
Sheep anemia is mostly chronic, the initial symptoms are not obvious, but the body temperature rises, reaching 40 ~ 41 ° C, breathing tight, difficult, loss of appetite, mental depression, standing still, cough, nasal discharge, sick nose The liquid is a large amount of serous secretions, and later becomes thick, sometimes the nasal fluid is purulent or bloody; the ruminant stops, the appetite is abolished, the eyelids are swollen, the conjunctiva is pale; finally, extreme weight loss, heart failure and death. The course of the disease is about 2 weeks. The auscultation of the heart is enhanced, the lungs are arpeggios, and the chest wall percussion has a prominent large voiced area behind the elbow.
In severe cases, it is difficult to stand or lie down. The conjunctiva, mucous membranes and skin are pale. Some of the sick sheep have diarrhea and pull the stinking water-like feces, leading to dehydration, weight loss, and finally failure. It often occurs in hot summer weather. Young sheep, pregnant sheep and malnourished sheep are often found. Young sheep often die suddenly without symptoms and the mortality rate is about 30%. Most of the dead sheep were examined for pneumonia or pleural inflammation, with purulent discharge or purulent lesions.
Sheep anemia diagnosis result
The sheep are weak and weak, the conjunctiva is pale, the vulva, the breast and the oral mucosa are markedly white, thin, bowed, and listless. Difficulty breathing after exercise, loss of appetite or lack of food, diarrhea, diarrhea, these symptoms can be diagnosed, further diagnosis requires laboratory diagnosis, check the number of red blood cells and hemoglobin reduction, it is best to carry out bacterial culture.
Prevention and treatment of sheep anemia
Anemia is only a symptom of the disease, and it should be comprehensively analyzed according to other manifestations of the diseased sheep. First of all, establish a breeding concept of “cultivating weight in prevention and prevention in treatmentâ€, insisting on prevention, paying attention to heatstroke prevention and ventilation in the hot season, keeping the enclosure dry and disinfecting regularly. For the newly purchased sheep, the insects are first dewormed after isolation and normal observation, and the insect repellent is used to completely deworm. The sick sheep should be isolated in time, take care of them and strengthen nutrition. Dyspnea can be treated with lincomycin (30 mg/kg body weight), amikacin (10 mg/kg body weight) or enrofloxacin and cephalosporin intramuscularly, twice daily, for 3 times. d, can also be mixed with streptomycin diluted (100 grams of purified water per gram) after spraying the respiratory tract; high body temperature can be used aspirin (0.5 mg / kg body weight), loss of appetite with vitamin B1, B12, vitamin C The effect is better, and the dehydrated person is supplemented with oral salt supplement or artificial salt plus glucose to drink, the effect will be better. Infusion should be slow to avoid symptoms of pulmonary edema or aggravation of pulmonary edema.
Nowadays, the management of many large-scale farmers is still in the rough state. It is believed that simply concentrating the sheep is a large-scale farming, the nutrient imbalance of the forage, the prevention and control measures of the disease are not perfect, the management is not in place, and the disease prevention and treatment system is not perfect, thus causing the sheep anemia. disease. Therefore, the farmers should pay more attention to these problems in the future, save the blood or return to the treatment for a lot of money!
