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
However, when the two types of enzymes are used in combination, there is no research on how their respective activities should be proportioned, how to reduce waste and obtain the best economic benefits.

Embodiment 1

[0098] The application example of the compound enzyme preparation of the present invention in pig breeding.

[0099] The feed compound enzyme preparation of the present invention is carried out in the pig farm of Shandong Yankuang Group ×× Breeding Co., Ltd. In the experiment, 320 Duroc×Landrace×York healthy piglets with a weight of about 15kg (produced by 200 sows from the farm, parity 3-4, birth date and age) were selected according to the principle of consistent weight and genetics , were randomly divided into 10 groups, of which 1 was the control group and 9 were the test group, each group had 4 repetitions, each repetition was 10, male and female were half and half, and the initial body weight of each group was not significantly different after significant analysis (P< 0.05). The diet was corn, wheat, soybean meal type. The enzyme preparation used in the test is powder, and the activity is as follows: 3800U / g≤xylanase activity≤5700U / g, 1800U / g≤β-mannanase activity≤2500U...

Embodiment 2

[0113] An application example of the feed compound enzyme preparation of the present invention in broiler breeding.

[0114] We chose to conduct the central test on the chicken farm of Fujian Longyan Yi Technology Co., Ltd. The test was designed according to the broiler breeds and the different additions of the enzyme preparation of the present invention in the diet. In the feed formula of the test group, the effective phosphorus was reduced by 0.075%, 0.1%, and 0.125% compared with the control group, and the rest were the same as the control group.

[0115]1000 healthy AA broilers with normal appetite, feed intake and date of birth were selected for each test. According to the principle of consistent body weight and genetics, they were randomly divided into 10 groups, 1 test group and 9 control groups. 5 repetitions per group, 100 pigeons per repetition. The test adopts liquid enzyme preparation, the activity is: 5060U / ml≤xylanase activity≤7600U / ml, 2400U / ml≤β-mannanase act...

Embodiment 3

[0129] An application example of the feed compound enzyme preparation of the present invention in meat duck breeding.

[0130] The central test site for the application of the feed compound enzyme preparation of the present invention in meat duck breeding is carried out in a duck farm in Zhangjiagang. 1000 healthy, normal and similar cherry valley meat ducks were selected for the experiment. According to the principle of consistent body weight and genetics, they were randomly divided into 10 groups, 1 control group, 9 test groups, 5 repetitions in each group, and 50 feathers in each repetition; the test meat ducks were fed in two stages (early stage, late stage), and fed separately. Feed for each period, the feeding period is about 42 days; when the test starts and ends, it should be weighed on an empty stomach in the early morning, and the individual weight of the test ducks should be recorded, and the feed consumption and death number of the test ducks in each group should b...

Abstract

The invention relates to an exogenous composite enzyme preparation special for feed industry and a preparation method and application thereof. The composite enzyme preparation comprises five kinds of water-soluble non-starch polysaccharide enzyme and phytase, namely xylanase, dextranase, mannose, cellulase and pectase. The activity mixture ratio of the contained water-soluble non-starch polysaccharide enzyme to the contained phytase is designed according to the kinds and the contents of the non-starch polysaccharide and the phytase in raw materials of a common feed, the synergistic effect between two kinds of the enzymes can be fully achieved, and the most scientific and economic mixture ratio is provided. The exogenous composite enzyme preparation can improve the degradation efficiency of non-starch polysaccharide anti-nutritional factors and phytic acid in the feed, remove the anti-nutritional effect thereof, improve the absorption and conversion rate of the feed and the utilization rate of phosphorus in the feed, substantially reduce the dosage of inorganic phosphorus and the production cost, bring considerable economic benefit to feed processing enterprises and farmers, greatly reduce the contents of nitrogen and phosphorus in animal excrement so as to reduce environmental pollution, and has remarkable social benefit.

Description

technical field [0001] The invention relates to an enzyme preparation for feed, in particular to a special exogenous compound enzyme preparation for feed industry and its preparation method and application. 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...
