Description

technical field [0001] The invention relates to a feed additive for preventing and treating porcine parvovirus infection. Background technique [0002] Porcine parvovirus can cause reproductive disorders in pigs, which are characterized by infecting sows, especially primiparous sows, producing stillbirths, deformed fetuses, mummified fetuses, abortions and sickly piglets, while the sows themselves have no obvious symptoms. Porcine parvovirus (PPV) is a member of the genus Parvovirus in the family Parvoviridae. The virus genome is single-stranded DNA, encoding VP1 and VP2 structural proteins and NS1, NS2, NS3 non-structural proteins. Among them, the structural protein genes vary greatly, but can induce the body to produce neutralizing antibodies. The disease is common in primiparous sows and is generally endemic or sporadic. At present, there is no effective drug treatment for this disease. Once the disease occurs, the affected sows and piglets should be isolated or elimina...
