The addition of MSP®IMMUNITY to the feed of lactating sows vaccinated with a bivalent vaccine containing Pasteurella multocida and Bordetella bronchiseptica strains increased the content of antibodies (IgG and IgA) in the colostrum and milk from the beginning and throughout the lactation period.
These preliminary data show that the addition of MSP®IMMUNITY to the feed could improve the transfer of lactogenic immunity (through the colostrum and milk) and protect newborn piglets from infection and reduce the use of antibiotics in livestock.
However, the mechanism of action underlying the adjuvant activity of MSP®IMMUNITY has not yet been determined. One hypothesis is that the product could induce the proliferation and migration, of the differentiated B lymphocytes secreting antibodies from the intestine to the mammary gland.
