How to prevent sheep disease in hot season

First, strengthen the feeding and management of summer sheep, the disease resistance is reduced, and it is easy to get sick. In order to improve the disease resistance of sheep, it is necessary to ensure the supply of sufficient nutrients for sheep, and feed concentrate once every morning and evening, 0.2kg to 0.5kg per adult sheep. Feed should be fixed and quantitative to prevent excessive or lack of nutrients. It is strictly forbidden to feed poisonous, moldy and contaminated feed. Clean drinking water should be given in time. Herding sheep in summer should go out early and return late, and let the sheep have more rest at noon to prevent heatstroke. The sheephouse should be nailed to screen doors and windows to prevent mosquitoes and flies.

Second, do a good job in environmental sanitation and disinfection. Summer is the season for the mass reproduction and spread of bacteria and viruses. In order to prevent the growth and spread of bacteria and viruses, the activity grounds and utensils of sheep houses and sheep should be kept clean and dry, and the feces and dirt in the enclosure should be cleaned and fermented every day. Sheep houses and appliances are disinfected with Baidu disinfectant or Weidao disinfectant once a week, and the floors of sheep houses and sports grounds are disinfected with 2%-4% caustic soda solution every semimonthly.

Third, immune injection is an important measure to prevent and control sheep disease. At present, there are many vaccines for infectious diseases in sheep. The times and time of immunization should be arranged reasonably according to the characteristics of various vaccines and the local incidence. Adult sheep are injected with sheep fast disease, sheep sudden onset, enterotoxemia, sheep black disease quadruple vaccine and sheep foot-and-mouth disease vaccine every spring and autumn. Pregnant ewes were vaccinated with lamb dysentery 30-20 days before delivery. Sheep should be vaccinated against sheep pox before summer, and sheep at the age of 6 months should be vaccinated with infectious pleuropneumonia on time.

Fourth, the parasites of regularly deworming sheep can be divided into two kinds: in vivo and in vitro. The parasite of sheep is a common and serious disease in the production of sheep. The mild ones are weak and emaciated, and the serious ones can cause a large number of deaths. Therefore, worms must be dewormed regularly. The internal parasites were repelled with albendazole and avermectin in spring and autumn, and the in vitro parasites were daubed with 1% trichlorfon solution or 0.05% phoxim solution.
