The application belongs to the technical field of composite materials, and particularly discloses a preparation method and application of a stress-resistant and
immunity-enhancing preparation for piglets, which is prepared by using
sodium iron
chlorophyll and
sodium selenium-rich acid as core blood supplement elements, collocating an
astragalus polysaccharide and a
cordyceps polysaccharide compound
polysaccharide system, combining functional oligosaccharides, antibacterial peptides and probiotics to construct an intestinal microecological regulation module, and supplementing with composite amino acids and vitamins to form a nutritional synergistic
system, and is prepared through gradient
sugar molecule inclusion, low-temperature microcapsule embedding and other innovative processes, so that the physical energy, qi and blood are supplemented simultaneously. The preparation can effectively reduce the incidence of
hypoglycemia in newborn piglets, improve the
disease resistance and
immunity of the piglets, relieve
weaning stress, improve the
weaning survival rate and
weaning weight, and simultaneously improve the nutritional supply of perinatal sows, reduce postpartum fatigue of the sows, improve milk quality and indirectly help the growth of the piglets.
