Application of atractylodes macrocephala polysaccharide and pachymaran as feed additive for improving weaning stress of piglets

Abstract

The invention discloses an application of atractylodes macrocephala polysaccharide and pachymaran as a feed additive for improving weaning stress of piglets, which belongs to the field of the feed additive. The application of atractylodes macrocephala polysaccharide and pachymaran as feed additive for improving weaning stress of the piglets is characterized in that the appropriate addition amountaccounts for 0.02%-0.08% of mass of a basic feed, the overhigh addition amount affect the growth performance, immunity and feed-to-weight ratio of the piglets, and the excessive low addition amount cannot achieve the effect; the atractylodes macrocephala polysaccharide and pachymaran is composed of atractylodes macrocephala polysaccharide and pachymaran according to a mass ratio of 1-2:1-2, and the content of polysaccharides in atractylodes macrocephala polysaccharide and pachymaran is 37.5%; and the application of atractylodes macrocephala polysaccharide and pachymaran as the feed additive for improving weaning stress of the piglets can effectively alleviate the early weaned stress of the piglets, improves the growth performance of the weaned piglets, and is a very good antibiotic substitute.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to the application of Atractylodes macrocephala polysaccharide as a feed additive for improving weaning stress of piglets. Background technique [0002] Pig farming is a pillar industry of modern animal husbandry, and its piglet production management is the most critical link in the pig breeding process, which determines the economic benefits of pig farming. According to the normal physiological condition of piglets, weaning should be a gradual process that lasts about 120 days. With the development of pig raising technology, in order to improve the economic benefits of pig raising, pig farms adopt intensive breeding and the weaning age of piglets is shortened to 21-28 days. This can easily lead to "early weaning syndrome" manifested in piglets with reduced appetite, digestive disorders, growth retardation, diarrhea and even death. The appearance of "early weaning syndrom...

Problems solved by technology

Chinese herbal decoctions are often inconvenient in actual animal husbandry production. With the advancement of Chinese herbal medicine extraction technology, the application of Chinese herbal polysaccharides in animal husbandry has received extensive attention. At present, most of the studies are on the monomers of traditional Chinese medicines, but the formulations based on the compatibility of traditional Chinese medicines The basic principle is "monarch, minister, assistant and mission", and the rational use of traditional Chinese medicine will produce the effect of "1+1>2"

The combined use of compound Chinese herbal medicines may be more effective than monomers, but there is little research on compound Chinese herbal medicines, and the specific mechanism of action on weaned piglets is still unclear
