Abstract

The invention relates to the technical fields of microorganism fermentation and nano, and provides a bio-synthesis method of nano zinc oxide by utilizing lactic acid bacteria and a nano zinc oxide composite feed addictive. The invention utilizes lactic acid bacteria to synthesize nano grade zinc oxide, and then develops a novel feed addictive which is rich in nano zinc oxide. The addictive is applied to a feed for suckling pigs, and the addition amount is less than 1000 ppm (by the weight of zinc oxide). The addictive can effectively prevent animals from zinc poisoning and reduce the environmental pollution caused by zinc, can also effectively prevent weaned pigs from diarrhea and improve the health level of intestinal tracts through the co-function of lactic acid bacteria and zinc oxide, and can even wholly or partially replace the antibiotic to reduce the antibiotic residue so as to improve the food safety.

Description

technical field

[0001] The invention relates to the fields of microbial fermentation and nanotechnology, and more specifically relates to a method for biosynthesizing nano-zinc oxide by lactic acid bacteria and a nano-zinc oxide compound feed additive. Background technique

[0002] Nano zinc oxide has unique properties. Nano-zinc oxide is a new type of high-function fine inorganic product, also known as ultra-fine zinc oxide, its particle size is generally less than 100nm. Due to the miniaturization of particle size and the increase of specific surface area, nano zinc oxide has surface effects, small size effects and macroscopic quantum tunneling effects that its bulk materials do not have.

[0003] Nano zinc oxide can be used as a feed additive. Adding nano-zinc oxide to animal feed as a feed additive, its high biological activity and absorption rate can effectively reduce diarrhea, reduce the ratio of feed to meat, and has no pollution to the environment. It is an ideal ...
