Problems solved by technology

The efficiency of stockpiling varies widely
Some anti-nutritional factors, such as tannins and trypsin inhibitors, exist in vegetable protein sources, such as soybean meal, which may cause damage to the absorption surface of the small intestine and affect the absorption of nutrients
In addition, the imperfect digestive system of young animals makes the protein in vegetable protein (such as bean cake powder) not be well utilized

Embodiment

[0018] Select 1200 1d healthy AA broiler chickens and randomly divide them into 5 treatment groups, each treatment has 6 repetitions, each repetition has 40 chickens, and they are respectively fed with the compound enzyme 0, 100, 200 obtained from the above-mentioned screening in the basal diet. , 300, 400g / t, feed powder throughout the whole process;

[0019] In terms of production performance: Compared with the control group, the average daily gain of 400g / t group and 300g / t group increased significantly by 7.53% and 6.55% (P<0.05), and the 400g / t group was better. Compared with the control group, the feed weight ratio of 200g / t, 300g / t, 400g / t group decreased significantly by 4.79%, 7.53%, 6.85% (P<0.05), and the 300g / t group was better. In 22-42d, the average daily gain of 400g / t group and 300g / t group increased significantly compared with the control group by 15.26% and 17.18% (P<0.05), and the 300g / t group was better. Compared with the control group, the average daily f...

Abstract

The invention discloses a complex enzyme for animal feed and application of the complex enzyme, wherein the complex enzyme consists of the following enzymic preparations in parts by weight: 3 parts of cellulase, 1 part of amylase, 3 parts of mannase, 3 parts of neutral protease, 2 parts of lipase, 2 parts of acid protease and 2 parts of xylanase. As for the application, the complex enzyme for animal feed can be added to broiler feed with an addition amount of 300g / t. By virtue of the complex enzyme disclosed by the invention, nutrient substances in the feed can be full digested, absorbed and utilized by animals, so as to improve nutrition digestibility of the nutrient substances in animals and the production performance of the animals; and the complex enzyme not only reduces economic cost but also relieves serious pollution of excrements on environment.

Description

technical field [0001] The invention relates to the technical field of enzyme preparation, in particular to a compound enzyme for livestock and poultry feed and its application. Background technique [0002] There are four main reasons for adding enzyme preparations to feed: 1. Degradation of anti-nutritional factors present in animal feed. These substances cannot be degraded by animal endogenous enzymes, thereby interfering with the normal metabolism of animals, resulting in indigestion of animals and decreased production performance. 2. Improve the utilization rate of starch, protein and minerals. These substances are either surrounded by fiber-rich cell walls, or in the form of certain structures that cannot be digested by the animal. 3. Degrade some specific chemical bonds in raw materials. These chemical bonds cannot be degraded by the animal's own enzymes, and more nutrients can be released after adding exogenous enzymes. 4. Since the digestive system of young anim...
