Abstract

The invention discloses a complex enzyme preparation special for crab formula feeds; the complex enzyme preparation is prepared by solving five monomeric enzymes such as neutral protease, cellulose, amylase, lipase and phytase into a water solution containing composite stabilizer; wherein, the neutral protease is 1000-3000 IU / g; the cellulose is 8000-16000 IU / g; the amylase is 5000-20000 IU / g; thelipase is 10-30 IU / g; the phytase is 500-800 IU / g. Adding 500-1000 g / t of the complex enzyme preparation of the invention on the basis of perfect compound feeds of Eriocheir sinensis, mud crab, bluecrab can obviously improve the rate of live weight growth, yields of crabs and the efficiency of the feeds, and reduce excretion of ammonian and phosphorus, alleviate the eutrophication degree of theaquaculture water, and prevent the infections disorders and improve the survival rate; the invention is a safe green feed additive without pollution nuisances and residuals.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a special compound enzyme preparation for crab compound feed. Background technique [0002] Chinese people have a long history of eating crabs. Among the crabs, the edible crabs mainly include Portunus trituberculatus, Portunus pelagics, Scylla serrata and Eriocheir sinensis. Crabs are rich in protein, trace elements and other nutrients, which have a good nourishing effect on the body. In recent years, studies have found that crabs also have anti-tuberculosis effects, and eating crabs is of great benefit to the recovery of tuberculosis. Traditional Chinese medicine believes that crabs have the effects of clearing heat and detoxifying, nourishing bones and marrow, nourishing tendons and activating blood, dredging meridians, sharpening limbs, healing wounds, nourishing liver yin, and filling gastric juice. It has a certain dietary effect on diseases such as congestion, inj...
