Abstract

The present invention relates to the technical field of fish meal and particularly relates to a fermented fish meal with high digestibility rate and a preparation method thereof. The preparation method comprises the following steps: A, strain preparation: microbial strains are subjected to a first seed culture, a second seed culture and a liquid fermentation to produce a fermented bacteria liquid; and B, inoculated fermentation: the fish meal is inoculated to the above fermented bacteria liquid at a weight ratio of 100: 30-50, the inoculated fish meal is put into a packaging bag attached with a pressure adjustable silica gel film, the sealed packaging bag is stored at room temperature to conduct a fermentation and the fermented fish meal with high digestibility rate is obtained when the pH drops to 3.0-4.0. The fermented fish meal with high digestibility rate is prepared by conducting the microbial fermentation of the fish meal, contains a lot of beneficial microbes, can improve the digestibility rate of proteins; and due to the metabolites produced during the fermentation and the degradation function of the fermentation substrate, the fermented fish meal with high digestibility rate has very complicated ingredients, and the quality of the fish meal protein is improved.

Description

technical field [0001] The invention relates to the technical field of fish meal, in particular to a fermented fish meal with high digestibility and a preparation method thereof. Background technique [0002] Fish meal is an indispensable high-quality protein source in animal feed. It has many advantages in feeding applications, such as high biological value, high energy value, high calcium and phosphorus content, high trace element content, and high digestibility. Therefore, fish meal has long been an aquatic product. The main source of protein, calcium, phosphorus and energy substances in feed and livestock feed. However, the digestion and utilization rate of existing fishmeal is relatively low. Therefore, seeking and developing some high-tech technologies that can improve and increase the utilization rate and conversion rate of plant protein has become a top priority for practitioners. Contents of the invention [0003] In order to overcome the shortcomings and deficie...
