Abstract

The invention provides a compound feed additive and a preparation method thereof, and belongs to the field of feed additives. The compound feed additive comprises a component A and a component B, wherein the component A comprises fermentation products of bacillus subtilis HDReM20, saccharomyces cerevisiae, lactic acid bacteria and bacillus licheniformis HDReM33; the bacillus subtilis HDReM20 is preserved in the China Center for Type Culture Collection on December 25, 2019, and the preservation number of the bacillus subtilis HDReM20 is CCTCC NO: M20191104; the bacillus licheniformis HDReM33 ispreserved in China Center for Type Culture Collection on December 25, 2019, and the preservation number of the bacillus licheniformis HDReM33 is CCTCC NO: M20191105; the component B comprises bacillus subtilis HDReM20, bacillus licheniformis HDReM33, bacillus coagulans and lactic acid bacteria. The compound feed additive is high in water body remediation efficiency and beneficial to industrial production and large-scale application. The preparation method can be used for simply and quickly preparing the compound feed additive.

Description

technical field [0001] The disclosure relates to the field of feed additives, in particular to a compound feed additive and a preparation method thereof. Background technique [0002] In 2018, China's total aquaculture output exceeded 50 million tons, accounting for more than 78% of the country's total aquatic product output. It is the only major fishery country in the world where the total amount of aquaculture aquatic products exceeds the total catch. With the increasing scale of aquaculture in our country, intensive and high-density farming has become the mainstream mode of aquaculture in our country. However, the subsequent deterioration of the water quality of the aquaculture water, the frequent outbreak of blue-green algae, and the frequent occurrence of aquaculture animal diseases have restricted the further improvement of the economic benefits of aquaculture. [0003] With the strengthening of the quality and safety management of agricultural products in my country ...
