Embodiment 1

[0027] A microbial enzyme feed additive, the formula is: amylase 30, cellulase 25, xylanase 9, pectinase 20, trypsin 30, ATPase 15, compound bacterial liquid 1; the compound bacterial liquid is acidophilus milk Bacillus and Bacillus licheniformis are mixed, and the weight ratio of Lactobacillus acidophilus and Bacillus licheniformis is 1:1. The feed additive can be prepared by fully mixing the components. The obtained feed additive was added to the feed, and 4.5 g of grass carp was fed for 56 days. Compared with the feed group without feed additive, the protein deposition rate increased by 10.27%, the weight gain rate significantly increased by 11.4%, and the disease rate decreased by 20.4%. than a significant drop of 17.57%. It can be seen that after the addition of microbial enzyme feed additives, the fat of the whole fish was significantly reduced and the content of muscle protein was increased, which improved the quality of the fish. The severity rate has been greatly in...

Embodiment 2

[0029] A microbial enzyme feed additive, the formula is: amylase 50, cellulase 35, xylanase 3, pectinase 10, trypsin 50, ATPase 10, compound bacterial liquid 2; the compound bacterial liquid is acidophilus milk Bacillus and Bacillus licheniformis are mixed, and the weight ratio of Lactobacillus acidophilus and Bacillus licheniformis is 2:1. The feed additive can be prepared by fully mixing the components. The obtained feed additive was added to the feed, and the chickens were raised for 30 days. Compared with the feed group without feed additive, the protein deposition rate increased by 9%, the weight gain rate significantly increased by 10%, the disease rate decreased by 15%, and the fat body ratio was significantly improved. down 14%. It can be seen that the addition of microbial enzyme feed additives significantly reduces chicken fat and increases muscle protein content; at the same time, feed additives can regulate the animal's digestive system, enhance the animal's absor...

Embodiment 3

[0032] A microbial enzyme feed additive, the formula is: amylase 40, cellulase 15, xylanase 5, pectinase 15, trypsin 40, ATPase 15, compound bacterial liquid 1; the compound bacterial liquid is acidophilus milk Bacillus and Bacillus licheniformis are mixed, and the weight ratio of Lactobacillus acidophilus and Bacillus licheniformis is 3:1. The feed additive can be prepared by fully mixing the components. The feed additive can be prepared by fully mixing the components. Add the obtained feed additive to the feed and feed the cattle for 60 days. Compared with the feed group without feed additive, the protein deposition rate increased by 12%, the weight gain rate increased significantly by 11%, the disease rate decreased by 17%, and the fat body ratio was significantly improved. down 17%. It can be seen that the addition of microbial enzyme feed additives significantly reduces beef fat and increases muscle protein content; at the same time, feed additives can regulate the anim...

Abstract

The invention discloses a microbial enzyme feed additive, its feed formula and preparation method. The additive is composed of the following components by weight: 30-50 of amylases, 15-35 parts of cellulases, 3-9 parts of xylanases, 10-20 parts of pectinases, 30-50 parts of trypsins, 10-20 parts of adenosine triphosphatases, and 1-2 of a composite bacterial liquid. The microbial enzyme feed additive of the invention comprises a variety of enzymes and microorganisms, and the formula composition is obtained through multiple experiments; various enzymes and microorganisms added to the feed formula can interact on each other and make adjustments so as to greatly improve the protein conversion rate, and meanwhile, the enzymes and beneficial microorganisms can also adjust the digestive system of animals and enhance the absorption of feed nutrition by animals. The microbial enzyme feed additive of the invention can be applied in various common feed. Of course, the feed formula in the invention is a most preferable scheme. The microbial enzyme feed additive in the invention is suitable to chickens, ducks, geese and other poultry, and is also suitable for pigs, cattle and sheep, as well ascan be applied in fish, shrimps and other aquacultures.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a microbial enzyme feed additive and its feed formula and preparation method. Background technique [0002] Breeding industry refers to the production sector that raises livestock and poultry to obtain animal products or draft animals by means of grazing, captive breeding or a combination of the two. It includes livestock breeding, poultry breeding, domestication of economic animals, etc. Aquaculture is an important part of my country's national economy. [0003] Feed is the foundation of the aquaculture industry. Only by continuously solving the problem of feed can the development of aquaculture be accelerated. [0004] However, the existing feed often has problems such as low protein conversion efficiency and malabsorption of nutrients. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a microb...
