Production of feed additive

Abstract

An additive of forage for increasing the content of peptide, the utilization rate of protein and the growth speed of animals is prepared from one or more kinds of feed protein through solid fermenting by bacillus and/or bacterium lactis and/or yeast.

Description

technical field [0001] The invention belongs to the field of fermentation engineering, in particular to a preparation method of a feed additive. Background technique [0002] Research practices in recent decades have shown that there are differences in the utilization of amino acids in feeds from different sources. Not only can diets formulated on the basis of the old protein amino acid theory fail to achieve optimal production performance, but the utilization of various amino acids in the feed by animals is not completely affected by the level of a single limiting amino acid, nor does it fully follow the classical theory of nutrition - "The Bucket Rule". In addition, animals cannot achieve optimal production status when they are fed homozygous diets or protein-amino acid balanced diets formulated according to the ideal amino acid pattern. Therefore, the traditional protein metabolism model - the view that protein must be hydrolyzed into free amino acids before it can be a...

Problems solved by technology

However, this invention needs to invest in expensive fermentation and separation equipment, the production process needs to consume a lot of energy and water resources, and also produces a large amount of waste water to be treated, so the production cost of this invention is still relatively high

The amount of peptides produced by this invention in the feed is about 200mg / kg, and the efficacy of small peptides in most of the feed proteins in the feed has not been brought into play
