The method of timely deworming immunity with sufficient forage to prevent the death of sheep in spring

Sheep

First, prepare enough forage for winter and spring. The phenomenon of thinness in winter and lack of spring in sheep is mainly due to the lack of forage in winter and spring, emaciation, nutritional overdraft, decreased resistance and death after infection. The main way to solve this problem is to prepare enough forage, not only overwintering forage, but also in spring. The forage reserve should be calculated according to the sheep stock and the number of lambs born in winter, and the forage reserve should not be less than 5 months. It is best to reserve a certain amount of silage forage every year.

Second, deworming should be carried out in due course. Sheep have a high incidence of parasites in spring, so it is necessary to do a planned deworming work, and deworming should be carried out in the winter of last year. The main cause of death of sheep in spring is nematode, and its pathogen is a variety of nematodes of Trichoderaceae, including blood spear, Oster, spear, Marshall, Cypress, thin-necked genus, thin-necked genus and other nematodes. Deworming can be treated with avermectin preparation, 0.3 mg per kilogram body weight, or albendazole preparation, 10-15 mg per kilogram body weight.

Third, immunization should be carried out on time. There are many infectious diseases in sheep in spring, such as sheep pox, clostridium blight, streptococcosis, mycoplasma pneumonia and so on. Each farm should be immunized on time according to the epidemic situation, especially in last autumn. In areas where there is a small ruminant epidemic, it is necessary to do a good job of full coverage immunization, once immunization, effective for three years.
