Lactobacillus plantarum fermented soybean meal and production method thereof as well as method for preparing compound feed for scophthalmus maximus

Abstract

The invention provides a lactobacillus plantarum fermented soybean meal and a production method thereof as well as a method for preparing a compound feed for scophthalmus maximus. The following technical scheme is adopted: the lactobacillus plantarum fermented soybean meal is characterized by being prepared from the following raw materials in parts by weight: 2-4 parts of lactobacillus plantarum (L. plantarum) P-8 and 96-98 parts of common soybean meal; the strain of the L. plantarum P-8 is separated from sour milk, and has excellent gastrointestinal tract digestive juice tolerance. The strain has been collected in China General Microbiological Culture Collection Center with the collection number CGMCC No.6312. The compound feed for scophthalmus maximus is prepared from the L. plantarum P-8 fermented soybean meal in stead of fish meal, and therefore, the problems of high antinutritional factor content, poor palatability, slow growth, damage on animal health and the like due to the adoption of other protein sources instead of the fish meal can be solved and the shortages of the prior art can be made up.

Description

technical field [0001] The invention belongs to the field of Lactobacillus plantarum soybean meal, and in particular relates to a soybean meal fermented by Lactobacillus plantarum, a production method thereof and a method for preparing turbot compound feed. Background technique [0002] my country is a large aquaculture country in the world, and its aquaculture output ranks first in the world. Usually the main protein source in aquatic compound feed is fishmeal, and the annual demand for fishmeal in my country exceeds 1.2 million tons. However, more than 2 / 3 of fishmeal needs to be imported at present, costing over 10 billion annually. Due to overfishing and environmental factors, the world's fishmeal resources are becoming increasingly scarce, and the price of fishmeal continues to rise, resulting in high feed costs, which seriously hinders the development of my country's aquaculture industry. Turbot is a representative species of northern mariculture. It is a typical car...

Problems solved by technology

However, ordinary soybean meal has the disadvantages of high content of anti-nutritional factors and poor palatability, which limits its proportion of replacing fish meal
