How to do basic epidemic Prevention in Mutton Sheep Farm

At present, the sheep industry has gradually become a new force in the rural breeding industry, but the traditional extensive management of sheep breeding is difficult to obtain greater economic benefits. With the development of animal husbandry, a variety of modern farms have emerged. How to do a good job of epidemic prevention has become the most important problem in all breeding farms. Once the epidemic occurs, it will seriously affect the development of animal husbandry and cause huge economic losses. Therefore, in order to control and prevent the epidemic disease in the original seed farm, certain measures should be taken and corresponding guidelines and standards should be established to ensure the continuation and stable improvement of the quality of livestock and poultry. In addition, the regulations on epidemic Prevention of Livestock and Poultry issued by the State Council should be strictly implemented to prevent the occurrence and spread of infectious diseases in livestock and poultry.

? 1 establish a sound and perfect epidemic prevention system

??? Epidemic prevention work is a complex system engineering, which involves from production to sales, from inside to outside, to the staff of the whole field, throughout the whole field, which is closely related to it. Therefore, epidemic prevention must be brought into normal management, with the participation of all personnel supervised and carried out by veterinary personnel. The principle of epidemic prevention, the system throughout every link, strict procedures to operate in order to avoid the occurrence of epidemic diseases, the epidemic prevention system can be truly implemented.

1.1 Scientific procedure disinfection is an important measure to cut off the route of transmission. Through regular disinfection, we can kill bacteria and viruses in the environment, reduce parasites and prevent the occurrence of diseases. A regular disinfection system should be established. First of all, a disinfection pool should be set up at the gate to often maintain the effective concentration of the disinfectant; secondly, under normal circumstances, it should be disinfected once a week and 3 times a week when the epidemic occurs. Disinfectants such as quicklime, caustic soda, organochlorine preparations, complex iodine and quaternary ammonium salts can be used to disinfect different places. Specific disinfection procedures: remove all kinds of dirt in the field, rinse the field with clean water, and then spray disinfection with disinfectant to ensure the quality of disinfection.

1.2 all-in-all-out system. Due to the use of "all-in-all-out" feeding mode, production and transportation are relatively concentrated, which may result in a large number of chicks, uneconomical use of brooding and breeding equipment, and so on. In the actual production, for large farms, the use of "full-in-all-out" system is less, generally using the whole house "full-in-all-out" system of production. When there are sheep in the barn, it is always difficult to thoroughly clean, rinse and disinfect. The all-in-all-out system can minimize the incidence through isolation, which is conducive to disease control.

1.3 records of personnel going in and out of registration, bathing and changing.

? 2 formulate scientific immunization procedures and carry out vaccination on time.

Immunization is an important measure to improve the specific resistance of the body and reduce the susceptibility of animals. However, if it is not used properly, it will often get unsatisfactory results. To this end, we should pay attention to:

2.1 develop a thorough immunization plan. Vaccination of all kinds of vaccines takes a certain period of time to produce strong immunity, so we should make a corresponding immunity plan according to the onset season of various infectious diseases and vaccinate according to the prescribed procedure.

2.2 there should be scientific immunization procedures. Livestock and poultry cannot be vaccinated when they are in poor health. Some maternal antibodies can also affect and interfere with the titer of antibodies, or even completely inhibit the production of antibodies. In order to prevent the occurrence of this phenomenon, maternal antibody surveillance should be carried out for some infectious diseases, such as unconditional, the time of initial immunization can be determined according to experience. Immunization will produce strong immunity to strong adult sheep, but not good to young sheep, weak sheep or sheep suffering from chronic diseases. On the other hand, for pregnant ewes, especially those before delivery, sometimes miscarriage and preterm delivery will be caused by driving, capture and vaccine response during vaccination, which will affect fetal development and immune effect. It should be noted that the above results should not be taken into account in disease threat areas and should be urgently prevented and vaccinated in order to ensure the health of sheep.

2.3 timely deworming and invigorating stomach. Parasites are important diseases that endanger the sheep industry. The main parasites are mites, tapeworms, gastrointestinal nematodes, Fasciola hepatica and so on. Deworming is carried out regularly, usually once a quarter, preferably with albendazole and ivermectin. Specific usage: sheep take albendazole 15 mg per kg body weight, while 0.1% ivermectin injection is injected intramuscularly at 0.2 ml per kg body weight of sheep, so that the combination of drugs has a better killing effect on the above-mentioned parasites.

The programmed control mode of sheep parasitosis changes the control of single parasite to the overall orderly control of main parasites, and the sporadic treatment to organized and continuous preventive measures. so that the parasites in the sheep can be comprehensively treated and prevented, and the effect of comprehensive control has been improved. Recommended drugs: there are some trade names on the market, such as pest control, avermectin, Alijia, Afortin, Kechongxing, etc., which is characterized by a wide anti-insect spectrum and strong killing effect on the vast majority of nematodes, external parasites and other arthropods (ineffective eggs). In addition, it also has the characteristics of high efficiency, low toxicity, safety and so on. In clinical application, antiparasite drugs have irreplaceable advantages: one is to control parasites in vivo and in vitro through internal administration, and the other is not to produce cross-resistance with other deworming drugs. Use procedure: (1) when ewes are close to delivery, prenatal deworming is carried out to avoid the "postpartum increase" of fecal worm eggs in 4-8 weeks after delivery. In areas with severe parasite contamination, deworming must be carried out 3-4 weeks after delivery. (2) the calves are generally dewormed for the first time from August to September of the same year to protect the normal growth and development of lambs. In addition, young animals before and after weaning are subject to nutritional stress and are vulnerable to parasites. Therefore, protective deworming should be carried out at this time. (3) the whole population was dewormed twice a year, and the larval deworming technique was adopted in late winter and early spring (February-March). Prevent the emergence of the "best part of spring"; deworming in autumn (August-September), prevent the emergence of the "best part of autumn" of adults and reduce the "best part of winter" of larvae. For the areas with serious parasites, deworming can be added again from May to June to avoid the occurrence of body surface parasitic diseases in winter and spring. 2.4 Quarantine monitoring. Tuberculosis and brucellosis should be quarantined and monitored regularly, at least once a year. Timely detection of positive sheep and culling treatment is the need to ensure the health of sheep and the safety of animal products.

? 3 the key point of comprehensive epidemic prevention is prevention.

Although infectious diseases are composed of sources of infection, routes of transmission, modes of transmission and susceptible animals, there are many factors that affect the epidemic, so comprehensive epidemic prevention measures must be taken to eliminate all unfavorable factors and adhere to the principle of self-breeding and self-rearing, which is not only beneficial to the breeding of livestock and poultry, but also avoids bringing in various infectious diseases when purchasing livestock and poultry. If it is necessary to introduce species from other units, it should not be purchased from the epidemic area. However, it is necessary to isolate and quarantine for 1-2 days after buying, and confirm that it is healthy and disease-free before mixing with the original animals. When introducing fine varieties from abroad, in addition to strengthening port quarantine, quarantine should also be conducted before entry, and when diseased livestock and poultry are found, they should be dealt with strictly immediately.
