Second, the prevention of disease prevention Injection is an important measure to effectively control the occurrence and spread of infectious diseases, in general, the spring sheep should do the following kinds of immunity.
(1) Sheep and lung disease: Sheep and lung disease is an acute, hot, septic disease caused by Streptococcus suis serotype. It is prevalent in the winter and spring, and early spring is a high incidence period between February and March. When the weather is bad, the number of morbidity and death increases significantly, and the mortality rate can reach more than 80%. To prevent the disease, sheep should be injected with streptococcus sucrose aluminum hydroxide formaldehyde in the early winter each year. The sheep, irrespective of its size, was injected subcutaneously with 3 ml and injected again 2 to 3 weeks after the first injection. The dosage was still 3 ml.
(2) Clostridium perfringens disease: Clostridium perfringens disease is a common disease in sheep in the spring and is usually acute, with acute onset, high mortality, and poor drug treatment. The best prevention methods currently rely on bacterins. In early spring, it can be prevented by injection of “rapid epidemic of sheepâ€, triple vaccine of enterotoxemia, or “rapid epidemic of sheep, fleas, diarrhea of ​​lambs, phytophthora of typhoid feverâ€. Before use, dissolve with 20% aluminum hydroxide colloidal saline solution and shake well. Regardless of the size of the sheep, either muscle or subcutaneous injection of 1 ml.
3. Strictly insect repellent spring. In the grazing process, the sheep drink the pond water and eat dirty grass, which is easy to infect the parasitic disease. Therefore, the flock should be dewormed in March-April. The internal parasites can be used levamisole, albendazole, insects, busters, etc., to drive external parasites can be used to heat the water to bathe the body of goats, or to kill invincible powder exterminator.
The main focus is on the prevention and control of ticks and schistosomiasis and other conventional deworming. Since the larvae are transmitted by cockroaches, prevention and control of cockroaches can not only effectively prevent the occurrence of sheep coccidiosis, but also improve the quality of the sheep and reduce the incidence and mortality. The high incidence of these two diseases is late spring and early summer. However, in practice, it is found that the disease can be onset as early as the beginning of March. At this time the sheep's constitution is weak, once the morbidity mortality is relatively high. The mistletoe on the body surface of the sheep mechanically damages the skin, causing itching and parasitism, causing the sheep to become restless, which in turn causes skin or wound rickets. When a large number of parasites parasitize, it can cause anemia, weight loss, stunting, and milk production in the sheep. Falling, hind limb paralysis. What's more, it can spread a large number of infectious diseases, such as schistosomiasis, sheep blood rosaiasis, anthrax, and brucellosis, which can directly or indirectly cause the death of sheep. The larvae disease is generally benign, but sometimes the mortality rate is as high as 46 to 100%. Sheep of different ages can be affected. There are multiple sheep within 1 year of age.
For the prevention of the above two diseases, the following treatment measures may be taken. The surgeon may wear double-line gloves, dip 2% solution of trichlorfon, and apply it to the inner part of the ear, tail, etc. of more mistletoe, once every half month. The gauze wrap sixty-six powder spread in the sheep body, into the sheep 50 to 70 grams, lambs 20 to 30 grams, once a month; with 1:150 of 40% dichlorvos emulsion emulsion spray the sheep, once every half a month.
Once the sheep only has the disease, can be used Bennier (mainly composed of acarbolin, etc.) drugs for treatment, while the use of penicillin to prevent secondary infection, when the body temperature is higher with the use of antipain analgesic pain medication.
First, prevent colds in hot springs, and the weather is changeable. Sheep are susceptible to colds. The cold-sick sheep suffer from a lack of energy, with low head and hearing loss, coughing and runny nose, elevated body temperature, no grazing, and no rumination. The diseased sheep can use intramuscular injection of compound aminopyrine 5 to 10 ml, or 30% of eminopyram 5 to 10 ml, and when the condition is severe, it can be combined with 1.6 million units of penicillin and 500,000 units of streptomycin. Can also be used ginger 100 grams, 2 green onions, chopped soup, add 100 grams of brown sugar mixed hot pot, 1 day 2, even for 2 days, the effect is very good.
