A kind of compound enzyme preparation for feed

Abstract

The present invention discloses a complex enzyme preparation for feed. The complex enzyme preparation is prepared from xylanase, galactosidase, beta mannanase, cellulase, beta glucanase, phytase, corn protein and trehalose powder. Adding of the complex enzyme preparation into animal feed can effectively improve the degradation efficiency of non-starch polysaccharide anti-nutritional factors and phytic acids in the feeds, eliminate the anti-nutritional effect, improve the absorption and conversion rate of the feed, improve the utilization of phosphorus in the feed, and largely reduce the using amount of inorganic phosphorus. The complex enzyme preparation in the invention is greatly optimized in match and reduced in adding amount, saves the cost while has a better effect, and has a livestock disease preventing effect.

Description

technical field [0001] The invention relates to a compound enzyme preparation for feed, belonging to the field of feed additives. Background technique [0002] Since the reform and opening up, my country's national economy has continued to develop at a high speed, people's living standards have improved significantly, and the demand for livestock products has also increased. The rapid development of animal husbandry has led to a sharp increase in the demand for feed. my country's per capita arable land is less than 1 / 2 of the world's, with a large population and relatively scarce resources. How to develop various plant resources to serve the development of animal husbandry and feed industries is crucial. In recent years, under the influence of soaring international energy prices, the production of corn ethanol has made a lot of profits, leading to a sharp rise in corn prices. As the main energy raw material for feed, corn accounts for a huge proportion in the feed formula, ...

Problems solved by technology

(3) Increase the reproduction of harmful bacteria in the back of the intestinal tract, increase the water content of the feces, make the breeding environment worse, and increase the chance of disease occurrence

This substance has a great negative impact on the absorption and utilization of nutrients in monogastric animals

The anti-nutritional effect of phytic acid is mainly caused by its strong chelating ability: (1) phytic acid and phosphorus and other trace elements (calcium, zinc, manganese, magnesium, copper, iodine, molybdenum) chelate to form a phytic acid-mineral compound substances, making these elements unavailable to animals

(2) Phytic acid directly chelates with protein to form an insoluble phytic acid-amino acid chelate under acidic conditions lower than the isoelectric point of protein, thereby reducing protein digestibility; in alkaline conditions higher than the isoelectric point of protein Under certain conditions, phytic acid first forms a phytic acid-mineral complex with mineral element cations, and then forms an insoluble phytic acid-mineral-amino acid ternary complex with amino acid chelation; these two types of phytic acid-amino acid chelation None of the substances can be hydrolyzed by protease, so it affects the digestibility of protein and minerals in the feed at the same time

(3) Phytic acid has the strongest chelation ability under acidic to neutral conditions, and the pH of most of the digestive tract is in this range. Phytic acid combines with digestive enzymes in animals, reducing the activity of digestive enzymes and reducing digestibility

At present, commercially available non-starch polysaccharide enzyme preparations often have a certain enzyme activity that is very high, and other enzyme activity ratios are extremely low or only symbolic, which cannot completely eliminate the anti-nutritional effect of SNSP. It is impossible to determine the enzyme activity and ratio according to the substrate amount and ratio of the enzyme, and even ignore the activity damage caused by the complexation of phytic acid

Poor pertinence to the content or type of feed anti-nutritional factors

[0007] The applicant’s previous application CN201210479019X disclosed a compound enzyme preparation for feed, which included some conventional SNSP enzymes and optimized the ratio, but still had the disadvantages of insufficient effect and high addition amount
