Embodiment 1

[0020] According to xylanase 10%, cellulase 10%, β-mannanase 8%, α-galactosidase 15%, acid protease 10%, medium temperature amylase 10%, glucoamylase 10%, carrier 27 The ratio of % is uniformly combined to obtain a special compound enzyme feed additive of corn soybean meal type, and its main component analysis guarantee value is: xylanase 6000U / g; cellulase 700U / g; β-mannanase 2500U / g; α-galactosidase 300U / g; acid protease 10000U / g; medium temperature amylase 600U / g; glucoamylase 20000U / g.

[0021] Add the additive at 0.2‰ of the weight of the full-price compound feed.

[0022] The experiment adopts a single factor completely random design, selects 750 AA broilers of similar origin, age and body weight, and randomly divides them into 3 treatments, each treatment has 5 repetitions, and each repetition has 50 chickens. Positive control group, negative control group and test group were respectively set up, fed with corn-soybean meal-based ration, corn-soybean meal-based ration w...

Embodiment 2

[0028] Xylanase 12%, Cellulase 15%, β-Mannanase 5%, α-Galactosidase 5%, Acid Protease 5%, Moderate Amylase 10%, Glucoamylase 5%, Carrier 43% Combining uniform proportions, a special compound enzyme feed additive of corn soybean meal type is obtained, and its main component analysis guarantee values ​​are: xylanase 7200U / g; cellulase 1000U / g; β-mannanase 2000U / g; α -Galactosidase 100U / g; acid protease 7500U / g; medium temperature amylase 600U / g; glucoamylase 10000U / g.

[0029] Add the additive at 0.5‰ of the weight of the full-price compound feed.

[0030] The formula in this example is more suitable for pigs, and the effect is very good.

[0031] The piglet experiment was carried out with the special compound enzyme feed additive of corn and soybean meal. The present embodiment is divided into a control group and a test group, and selects 48 piglets with an average body weight of 9.08 kg and is divided into two groups, each group is divided into three repetitions (columns), a...

Abstract

The invention provides a corn bean pulp type feed complex enzyme additive and an application thereof. The complex enzyme additive comprises the components based on weight percentage: 10%-15% of xylanase, 8%-15% of cellulase, 3%-8% of beta-seminase, 5-15% of alpha-galactosidase, 5%-10% of acid protease, 10%-20% of moderate temperature amylase, 5%-10% of glucoamylase and 7%-54% of carrier. The complex enzyme additive can decompose the nutrient s in the corn bean pulp, a mass of anti-nutritional factors which are hard to digest by animals such as the crude fiber and the like, so that energy in the corn bean pulp can be abundantly explored, the digestion capability of the animals to the corn bean pulp type feed can be improved, and the material-meat ratio can be reduced; the digestibility of the nutrient substance and the appearance metabolic energy can be improved, and the microorganism quantity of the ileum can be reduced; the corn bean pulp type feed complex enzyme additive has the advantages of being high-efficiency, specific, small in additive amount and the like compared with the similar additive; and after the complex enzyme additive is used, the growth of the animals can be promoted, and the feed converting efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of livestock feed, and relates to a feed additive, in particular to a corn soybean meal-type feed compound enzyme additive and an application thereof. Background technique [0002] At present, corn and soybean meal are often used as livestock feed in animal husbandry, but corn and soybean meal-based feed contain anti-nutritional factors such as trypsin inhibitors and plant lectins, which greatly affect their nutritional components, and there are still some substances in the feed that are difficult to be digested. Carbohydrates digested by livestock and poultry, such as β-mannan, α-galactoside, etc., are also important factors affecting the nutritional value of corn and soybean meal-based feeds, making it difficult for the nutrients in corn and soybean meal-based feeds to be fully digested and absorbed by livestock and poultry , not only reduces the feed utilization rate, but also affects the growth and devel...
