Feed for improving piglet immunity and preparation method thereof

Abstract

The invention relates to a feed for improving the immunity of piglets, which includes main ingredients and auxiliary materials: the raw material components and parts by weight of the main ingredients are: 2-5 parts of wheat bran, 30-40 parts of cornmeal, 10-15 parts of soybean meal, and piglet compound 0.5-1 part of feed additive; the supplementary material is astragalus polysaccharide powder, and the parts by weight are 0.02-0.03 parts. The preparation method of the feed for improving the immunity of piglets is as follows: mixing each raw material component of the main ingredient and crushing it into piglets. Accept the powder residue, and then mix the auxiliary materials in the main material. Astragalus polysaccharide is an interferon inducer. Its antiviral principle: stimulate the function of macrophages and T cells, increase the number of E-ring forming cells, induce cytokines, promote the induction of interleukins, and make animals produce Endogenous interferon, so as to achieve the purpose of anti-virus, its taste is slightly sweet, suitable for piglets to take.

Description

technical field [0001] The invention relates to a feed for piglets, in particular to a feed for improving the immunity of piglets and a preparation method thereof. Background technique [0002] At present, most piglet feed ingredients in my country are mainly composed of corn, wheat bran, soybeans, rapeseed cake, silkworm chrysalis, fish meal, bone meal, calcium powder, and salt. Extremely sensitive to temperature drops. Newborn piglets are small in size, have a relatively large body surface area per unit weight, lack of thick coat and underdeveloped subcutaneous fat, so their body temperature loses quickly and recovers slowly in a low temperature environment. The most suitable temperature for piglets is about 35°C within 6 hours after delivery, 32-34°C within 2 days, and can gradually drop from 30°C to 25°C after 7 days of age. The lack of breast milk makes piglets very susceptible to diseases such as foot-and-mouth disease, blue ear disease, and epidemic diarrhea. Althoug...

Problems solved by technology

The most suitable temperature for piglets is about 35°C within 6 hours after delivery, 32-34°C within 2 days, and can gradually drop from 30°C to 25°C after 7 days of age. The lack of breast milk makes piglets very susceptible to diseases such as foot-and-mouth disease, blue-ear disease, and epidemic diarrhea. Although some feeds are overcome by traditional Chinese medicine compositions, the taste of feed decreases, the food intake of piglets decreases, and piglets grow slowly.
