Functional mixed additive and application thereof

Abstract

The invention provides a functional mixed additive and application thereof. The functional mixed additive comprises Brady yeast, and the functional mixed additive can obviously improve piglet diarrhea, promote piglet growth and improve piglet survival rate. Under the condition of weaning or other stress of piglets, feed added with the functional mixed additive can effectively protect intestinal tracts, promote the integrity of epithelial cell morphology and structure, good growth of microvilli, tight epithelial connection and reasonable thickness of a mucus layer, improve the digestion and absorption of energy and nutrients of the piglets, and further promote the growth and development of the piglets. The functional mixed additive can effectively replace antibiotics, and the problems of influence of the antibiotics on ecological environment and drug resistance are solved.

Description

technical field [0001] The invention relates to the field of animal nutrition and health, more specifically, to a functional mixed additive and its application. Background technique [0002] Diarrhea in piglets in the farrowing room of modern breed-scale farms is common at present. According to data survey, piglet diarrhea in farrowing rooms of some pig farms is very serious, and the mortality rate is as high as 80%. Pig farms of different scales have occurred in different growth stages of suckling piglets, which has brought significant economic losses to pig farms. [0003] The intestine is an important organ for animal digestion, absorption and immunity, and has a profound impact on the growth, development and health of pigs, so there is a saying that "raising pigs is raising the intestines". To ensure gut health, it is important to ensure that the gut mucosal barrier in pigs is intact and functional. Generally, the intestinal mucosal biological barrier includes mechanic...

AI Technical Summary

Problems solved by technology

[0004] At present, antibiotics and high-dose zinc oxide are commonly used in clinic to inhibit pathogenic bacteria and improve the immune protection ability of the body, so as to maintain the intestinal morphology and the functions of various parts of the digestive system to control diarrhea in piglets. However, due to the long-term use of antibiotics It can cause pathogenic microorganisms to develop drug resistance, coupled with their residues in animal products and the long-term pollution of the ecological environment caused by antibiotics and zinc oxide, these are serious threats to human health and the environment on which human beings depend. We need to start from Looking for a more effective measure to improve intestinal health and reduce diarrhea in piglets from the perspective of piglet nutrition
