How can sheep farmers prevent sheep diseases? Six major measures to master
1. Doing a good job of scientific feeding and management is an important foundation for preventing sheep diseases. Practice has proven that most sheep diseases are caused by improper feeding and management. Based on the living habits of sheep, do a good job with the three words "eat, housing, movement": Eat - feed enough grass, supplement concentrate, and standardize the formulation of the daily ration. Housing - ventilation in summer, warmth in winter, clean and hygienic pens that are dry. Movement - housed sheep flocks need exercise, and sheep in late pregnancy should be prevented from falling.
2. It is forbidden to buy sheep from epidemic areas. Sheep purchased from non-epidemic areas should also first be isolated and raised for 1 month, and only after it is truly confirmed that they are disease-free can they be mixed into one's own already-raised sheep flock.
3. Do a good job of vaccination immunization with vaccines and bacterial vaccines (preventive injections). In most areas, the following 4 types of vaccines must be injected:
(1) Goat pox attenuated live freeze-dried vaccine: dilute 50 times with normal saline. Regardless of the size of the sheep, inject 0.5 ml intradermally on the lower side of the tail base, once a year. (2) Sheep tetravalent inactivated vaccine: can prevent 4 infectious diseases (braxy, sheep sudden death disease, enterotoxemia, and lamb dysentery). Inject twice a year, which can be scheduled once each in March and September. (3) Goat contagious pleuropneumonia aluminum hydroxide bacterial vaccine. It can be scheduled once a year in April, by intramuscular or subcutaneous injection. For sheep under 6 months of age, use 3 ml per animal; for sheep over 6 months of age, use 5 ml per animal. (4) Bovine type O foot-and-mouth disease inactivated vaccine, inject twice a year, with the dosage according to the instructions.
4. Disinfect sheep sheds regularly. It is best to disinfect once every 10-15 days. The disinfectants available for selection include 0.5% peracetic acid solution, double-chain quaternary ammonium salt (Minxing No. 5 disinfectant), 3% Lysol solution, and Kangduwei 400-fold dilution.
5. Deworm regularly. During the period when goats are grazing and mutton sheep are housed and fed green grass, they are susceptible to parasitic diseases. Deworming once each season is required. The following deworming drugs can be selected: (1) Albendazole (also called Kangrumin). Administer orally at 15 mg per kg of body weight. (2) Levamisole. Tablets, 10 mg per kg of body weight; injection, 7.5 mg per kg of body weight, intramuscular injection. This drug has relatively large side effects, so use it with caution. (3) Ivermectin (Miechongding). It can simultaneously eliminate internal nematodes and external parasites (lice, ticks, mites), but it is ineffective against trematodes and tapeworms. For injection use, 0.2 mg per kg of body weight, by subcutaneous or intramuscular injection; for powder use, 0.2 g per kg of body weight, which can be mixed into a small amount of concentrate for feeding or mixed evenly with water and administered orally. (4) Mebendazole. This product has the excellent properties of broad spectrum, high efficiency, and safety. It can eliminate various internal parasites, and is administered orally at 15 mg per kg of body weight.
6. Breeding sheep farms should have epidemic prevention facilities and an epidemic prevention management system. Set up a veterinary room and a sick sheep isolation shed downwind of the sheep shed (more than 100 m away from healthy sheep sheds; sheep manure and waste should be transported to a downwind place more than 200 m away from the sheep shed for stacking and fermentation treatment; when outside personnel request to visit the breeding sheep farm, they must comply with the farm's epidemic prevention system without exception, obtain the veterinarian's consent and the farm manager's permission, and may enter only after strict disinfection. Once an infectious disease occurs, emergency prevention and control measures should be taken, doing a good job of isolation, treatment, disinfection, and disposal, and reporting the epidemic situation to the competent department in a timely manner.
