Problems solved by technology

Clinically, the main problems of porcine reproductive and respiratory syndrome vaccines are: first, it takes a long time for the vaccine to produce an immune response; second, porcine reproductive and respiratory syndrome vaccines do not have complete protection, especially inactivated vaccines cannot Stimulate cellular immunity; third, attenuated porcine reproductive and respiratory syndrome vaccine can exist in the body tissues of immunized pigs for several weeks and spread from vaccinated pigs to susceptible pigs

Abstract

The invention provides a feed capable of preventing and treating a porcine reproductive and respiratory syndrome. The feed comprises the following raw materials: an immune preparation for preventing and treating the porcine reproductive and respiratory syndrome, corn, soybean meal, fish meal, calcium hydrophosphate, wheat, edible salt, composite additives of trace elements, a multivitamin additive, lysine and methionine. The included immune preparation is capable of enhancing the cellular immunity and the humoral immunity of the organism through the organism regulation action, activating immune cells, inducing generation of interferon and preventing survival and reproduction of viruses in porcine somatic cells, and plays a role in resisting the porcine reproductive and respiratory syndrome.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for preventing and treating porcine reproductive and respiratory syndrome. Background technique [0002] Porcine reproductive and respiratory syndrome (Porcine Reproductive and Respira-tion Syndrome, PRRS) is an acute contact infectious disease caused by porcine reproductive and respiratory syndrome virus, which mainly causes reproductive disorders in pregnant sows and respiratory symptoms in piglets, leading to Abortion, stillbirth, mummified fetus, weak piglets and other reproductive disorders and a large number of deaths of piglets. The disease is an acute and highly lethal infectious disease. The virus is highly pathogenic and spreads quickly. The morbidity and mortality of pigs are high. The incidence of piglets can reach 100%, and the mortality rate can reach more than 30%. The rate can reach more than 30%. Fattening pigs and sows can also die. [0003] There is no e...
