Animal Feed Additive Acid Protease

Product Description

Low utilization of animal feed protein can lead to undigested protein fermentation in the hindgut to produce harmful substances such as hydrogen sulfide, ammonia, and methyl phenol, which not only affects the intestinal health of animals, causes diarrhea and reduces production performance, but also aggravates the environmental pollution caused by the farming industry. Improving the digestibility of feed protein is an important measure to solve this problem. Acid protease, derived from Aspergillus niger strains, can effectively hydrolyze proteins under low pH conditions and is used in the feed industry as an exogenous enzyme in animal feeds, feed additives, and feed compositions, or for processing vegetable proteins. The active center of acid protease contains aspartic acid, which can extensively sever peptide bonds in amino acids, preferring to sever peptide bonds between aromatic or hydrophobic amino acid residues at both ends, especially between aromatic amino acids and other amino acids, producing small peptides and amino acids.

Feed enzymes are produced by microbial fermentation and are added to feed to improve digestion and utilization of feed or improve metabolic efficiency in animals. Enzymes that can be added to feed include Protease Mix, Thermostable Phytase, Highly Efficient Phytase, NSP Enzyme, Lipase, Pectinase, Cellulase, α-Amylase, Alpha- Galactosidase, Beta-Glucanase, Glucose Oxidase, Thermostable Acid Protease, Acid Protease, Thermostable Acid Beta-Mannanase, Beta-Mannanase,  Xylanase, etc.

About 70% or more of poultry sticky wheat rations worldwide have enzymes added to them, and nearly 90% of poultry feeds in Europe contain enzymes.

Enzyme preparations are divided into three main categories：

Non-starch polysaccharidases

Non-starch polysaccharide enzymes include xylanase, β-glucanase, β-mannanase, cellulase, α-galactosidase, pectinase, etc., which act on the corresponding NSP in the feed. livestock and poultry do not secrete this type of enzyme and must be added exogenously from the feed, which is the main enzyme preparation for feeding.

Phytase

Phytase has a special spatial structure that sequentially separates phosphorus from phytic acid molecules and degrades phytic acid (salt) into inositol and inorganic phosphorus while releasing other nutrients bound to phytic acid (salt).

Endogenous digestive enzymes

Endogenous digestive enzymes are enzymes that can be secreted by the animal’s digestive tract itself, mainly proteases, amylases, and lipases. In some special cases, endogenous enzymes also need to be supplemented by the feed.

Product Feature

PH and Temperature:

Acid protease’s optimum reaction pH is low, and basically coherent with the digestive system of livestock and poultry. Make up for a lack of livestock and poultry intestinal secretion of endogenous protease, improve protein digestibility, and reduce metabolic diarrhea when used in feed additives. The effective pH range is 2.0 to 6.0, the optimum pH is 4.0.

When the temperature is lower than 30℃ or higher than 45℃, the relative enzyme activity decreases obviously. The effective temperature range and the optimum temperature are 35-40℃, and 40℃, respectively.
