Abstract

The invention relates to a usage of pineal shell polysaccharide as an addition agent in water product and poultry feeding stuff, and the invention also provides a feeding stuff containing the pineal shell polysaccharide. The feeding stuff added with the pineal shell polysaccharide has the functions of Qi and spleen tonifying, disease-resistance, body strengthening, food effect improvement and growth acceleration, can improve the immunity of the poultries, promote the meat quality of the poultries, and can also improve the egg production and egg product quality of the poultries. The sources of the pineal shell polysaccharide are rich, the raw material is byproduct pineal shell after the processing of pineal, the extraction method is mature, the cost is low, and the pineal shell polysaccharide added into the poultry feeding stuff can reduce the consumption of ordinary feeding stuff and feeding cost.

Description

Technical field:

[0001] The invention provides the use of pine nut chitosan as an additive in aquatic products, livestock and poultry feed, adding pine nut chitosan to the feed to achieve the purpose of improving animal immune function and promoting animal growth, and is used for raising poultry and livestock. It belongs to the technical field of feed production. Background technique:

[0002] Polysaccharides are a class of natural macromolecular polymers connected by glycosidic bonds between aldoses or ketoses. Polysaccharides are widely sourced in nature, especially in higher plants, animals, microorganisms, and seaweeds.

[0003] In the field of livestock and poultry including aquatic products, how to enhance the immune function of the cultured animals, so as to improve the disease resistance and growth rate, is a common concern. In particular, the industrialized breeding method has caused the occurrence of various diseases, which has become one of the key factors restr...
