Feed for suckling piglets and preparation method thereof

Abstract

The invention discloses a feed for suckling piglets. The feed comprises, by mass, 30-70 parts of corn, 10-30 parts of soybean meal, 5-20 parts of fish meal, 5-20 parts of whey powder, 5-10 parts of rice protein powders and 1-3 parts of compound premix. The feed is prepared by the following steps that (1) corn and soybean meal are mixed with water and then the mixture is crushed to 40-80 mesh usinga colloid mill to obtain a mixture A; (2) the mixture A is placed in a bucket, protease is added to the mixture A, and enzymatic hydrolysis of the mixture A is carried out for 5 to 6 hours to obtainan enzymolysis product B; (3) after the enzymolysis is completed, the temperature of the bucket is heated to>=60 DEG C to promote protease inactivation. As macromolecules in the corn and the soybean meal are decomposed into small peptides and amino acids by enzymolysis, and allergic proteins and anti-nutritional factors in the soybean meal are eliminated simultaneously, diarrhea caused by allergicreactions and anti-nutritional factors in early weaned piglets is reduced.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a feed for suckling piglets and a preparation method thereof. Background technique [0002] With the development of the pig industry, the weaning age of piglets continues to advance, often leading to the occurrence of "early weaning syndrome" in piglets, manifested as diarrhea, reduced feed utilization, and digestive disorders. [0003] Current studies have found that the main reason for the occurrence of "early weaning syndrome" is: the small intestinal mucosa, as the main place for digestion and absorption of nutrients, undergoes tremendous changes in shape, structure and function during the weaning stress period, the height of intestinal villi decreases, and the crypts Increased depth, insufficient activity of duodenal digestive enzymes, low immunity of piglets and many other problems. [0004] In addition, after piglets are weaned, they change from breast milk to solid feed wit...

AI Technical Summary

Problems solved by technology

[0005] In order to solve early weaning syndrome, animal producers will add a large amount of antibiotics to piglet feed to improve the disease resistance of piglets and reduce the growth of harmful microorganisms. However, the main cause of early weaning syndrome in piglets is not harmful microorganisms. Digestive and absorption functions are affected, the existence of anti-nutritional factors and the decline of immunity are the main reasons. On the one hand, long-term use of antibiotics in feed cannot suppress nutritional diarrhea, and antibiotics will destroy the balance of the digestive tract microenvironment and easily cause endogenous infections

On the other hand, the drug resistance brought about by the abuse of antibiotics has adverse effects on human health and the environment.
