A kind of high-free feed for sows capable of preventing and treating epidemic diarrhea in suckling piglets and its preparation method

Abstract

The invention discloses an anti-porcine epidemic diarrhea virus (PEDV) hyperimmune yolk powder, a sow hyperimmune feed capable of preventing the porcine epizootic diarrhea (PED) of a suckling piglet, and a preparation method of the sow hyperimmune feed. The anti-PEDV hyperimmune yolk powder is prepared by adding sodium alginate and astragalus polysaccharide in an anti-PEDV yolk solution, spraying and drying. The anti-PEDV hyperimmune yolk powder is contained in the feed for the milking sow and the pregnant sow, by using the feed provided by the invention, the immunity failure of a PEDV vaccine of the sow, caused by the immunosuppressive diseases like the common blue air disease, is avoided in various pig farms; the high-intensity labor caused by repeated perfusion of the anti-PEDV hyperimmune yolk powder for the suckling piglet, the stress on the suckling piglet and the risk of missed doses caused by the artificial negligence are also avoided, and the occurrence of the porcine epizootic diarrhea (PED) of the suckling piglet is prevented to the utmost extent in a way that the labor and the time are saved.

Description

technical field [0001] The invention relates to a high-free feed for sows capable of preventing and treating epidemic diarrhea (PED) of suckling piglets and a preparation method thereof. Background technique [0002] Porcine Epidemic Diarrhea (PED) is an acute, highly contagious intestinal infectious disease of pigs caused by Porcine Epidemic Diarrhea Virus (PEDV), which can occur in pigs of various ages. But the most serious harm to suckling piglets. Clinically, diarrhea, vomiting and dehydration are the main features. Once the suckling piglets get sick, it often leads to high mortality or even 100% death of the suckling piglets, and the loss of the pig farm is very serious. The disease was first reported in the UK in 1971 and was identified as a disease caused by a coronavirus in 1978. In my country, PEDV was isolated for the first time in 1980. Since then, there have been reports of PED in many places, and the epidemic range has continued to expand. Since 2010, the har...

Problems solved by technology

If in order to ensure better results, it is necessary to infuse high-immune antibodies twice or even multiple times, but it is time-consuming, laborious and stressful to infuse each newborn piglet multiple times, and it cannot be guaranteed that each worker can ensure that each piglet If you get enough antibodies, it is easy to miss the dose, which makes the prevention and treatment effect difficult to be stable and effective.
