Small peptide additive for porcine feed and preparation method thereof

Abstract

The invention provides a small peptide additive for porcine feed and a preparation method thereof; the small peptide additive for porcine feed is characterized in that the additive is prepared by mixing base materials, saccharomyces cerevisiae liquid, lactobacillus acidophilus liquid, bacillus subtilis liquid and water according to a weight ratio of 100:3-4:3-4:5-7:35-4, and performing solid fermentation; the base materials comprise 50-70 wt% of soybean meal, 4-5 wt% of rapeseed meal, 10-15 wt% of fish meal, 5-8 wt% of vinasse, 2-5 wt% of corn starch, 1-3 wt% of wheat bran, 1-3 wt% of molasses, 1-3 wt% of yellow mealworm, and 0.5-1 wt% of sodium carbonate. The small peptide additive for porcine feed of the invention can increase the synthesis speed of protein for pig body, promote food ingestion of pigs, increase appetite, improve immunity, promote the absorption of mineral elements by pig body, regulate various physiological actions of the body, reduce stress, and improve the nutritional status of pig body.

Description

technical field [0001] The invention relates to a small peptide additive for pig feed and a preparation method thereof, in particular to an antibiotic-free mixture obtained by mixing protein raw materials and auxiliary materials, which is sterilized by high-temperature cooking, and then obtained by solid-state fermentation of compound probiotics microorganisms. Oxygen factor, a pig feed small peptide additive rich in prebiotic small peptides and prebiotic factors, and a preparation method thereof. Background technique [0002] Traditional nutrition theory holds that protein must be digested into free amino acids before it can be absorbed and utilized by the digestive tract. Protein nutrition is amino acid nutrition. The new research shows that after the protein is degraded by the digestive tract enzymes into free amino acids and various small peptides. Small peptides are directly absorbed and utilized by animals in the complete form and free amino acids at the same time. P...
