Complex enzyme preparation special for large yellow croaker formula feeds

Abstract

The invention discloses a complex enzyme preparation special for large yellow croaker formula feeds; the complex enzyme preparation is prepared by solving three monomeric enzymes such as neutral protease, amylase and lipase into a water solution containing composite stabilizer; wherein, the neutral protease is 1000-3000 IU / g; the amylase is 5000-20000 IU / g; the lipase is 10-25 IU / g. Adding 500-1000 g / t of the complex enzyme preparation special for large yellow croaker of the invention on the basis of large yellow croaker full-rate formula feeds to feed can obviously improve the special growth rate of the large yellow croaker, improve the efficiency of the feeds, alleviate the eutrophication degree of the aquaculture water, and prevent the infections disorders and improve the survival rate, and reduce the fat percentage of the large yellow croaker; the invention is safe without pollution nuisances and residuals; and using the large yellow croaker cultivated by the complex enzyme preparation satisfies the hygienic requirements of Green foods.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a special compound enzyme preparation for large yellow croaker compound feed. Background technique [0002] Large yellow croaker is a unique fish with high economic value in my country. Its meat is delicious and nutritious. It was once one of the four major marine economic fish in my country. Over the past 30 years, due to predatory fishing, natural resources have been increasingly depleted. With the success of large yellow croaker artificial fry technology in Fujian, Guangdong, Zhejiang and other provinces and cities along the southeast coast of my country, cage culture of large yellow croaker has developed rapidly. At present, large yellow croaker has become one of the main mariculture species in my country. With the continuous increase of the cage culture density, the continuous improvement of the production level and the degree of intensification, many pr...

Problems solved by technology

Judging from the current research and application situation, there are many reports on enzyme preparations in livestock and poultry and freshwater aquatic feeds, but there are few reports on feed enzyme preparations for seawater fish. Therefore, it is very important to develop special enzyme preparations for seawater fish. necessary
