Anti-diarrhea yolk antibody feed additive for swine and injection formulation, and preparation method

Abstract

A feed additive containing yolk antibodies against diarrhea in pigs. The antibodies are preparing from bacilluscoli, epidemic diarrhea or rotavirus, or immunizing non-immunitive hens laying eggs with combined vaccine of bacilluscoli and / or epidemic diarrhea and / or rotavirus, then collecting yolks of the hens. A yolk antibody injecting agent, which is prepared from bacilluscoli, epidemic diarrhea or rotavirus, or immunizing non-immunitive hens laying eggs with combined vaccine of bacilluscoli and / or epidemic diarrhea and / or rotavirus, then collecting yolks of the hens.

Description

technical field [0001] The invention relates to an anti-swine diarrhea egg yolk antibody feed additive, an anti-swine diarrhea egg yolk antibody injection and a preparation method thereof. Background technique [0002] Pig is an important livestock product. As a food production resource, it plays a very important role in people's life. However, the morbidity and mortality of pigs are very high in my country, especially in southern provinces, where the mortality rate of pigs reaches 8~ 12%, most of which are caused by diarrheal diseases, and diarrheal diseases are mainly caused by Escherichia coli, infectious gastroenteritis, epidemic diarrhea and rotavirus, which seriously endanger the development of animal husbandry. However, for Porcine diarrhea disease, we still stay at the level of passive treatment of large amounts of drugs when the symptoms of pigs appear after the onset of the disease, ignoring the role of improving the ability of the pig's own b...

[0002] Pig is an important livestock product. As a food production resource, it plays a very important role in people's life. However, the morbidity and mortality of pigs are very high in my country, especially in southern provinces, where the mortality rate of pigs reaches 8~ 12%, most of which are caused by diarrheal diseases, and diarrheal diseases are mainly caused by Escherichia coli, infectious gastroenteritis, epidemic diarrhea and rotavirus, which seriously endanger the development of animal husbandry. However, for Porcine diarrhea disease, we still stay at the level of passive treatment of large amounts of drugs when the symptoms of pigs appear after the onset of the disease, ignoring the role of improving the ability of the pig's own body to resist pathogens in the prevention and treatment of diarrhea diseases, the result: not only laborious and laborious , high cost, unsatisfactory effect, some drugs even remain in pigs, which seriously affects the quality of livestock products, and a large amount of drug use also leads to drug resistance of bacteria, which is not conducive to the prevention and control of diseases
