Biological fermentation feed for abalones as well as preparation method and application thereof

Abstract

The invention relates to the field of biological feeds, and particularly provides a biological fermentation feed for abalones as well as a preparation method and application thereof. The biological fermentation feed for the abalones comprises a fermentation base material and fermentation bacterium fluid; the fermentation base material consists of the following components in parts by weight: 35-40parts of corn, 25-35 parts of soybean meal, 20-40 parts of kelp powder, 10-25 parts of fish meal, 8-12 parts of stone powder, 2-4 parts of calcium dihydrogen phosphate and 0.15-0.25 part of compound enzymes; the fermentation bacterium fluid is produced by expanding propagation of composite bacterial strains including bacillus licheniformis, lactobacillus acidophilus, bifidobacteria, pediococcus pentosaceus, candida utilis and saccharomyces cerevisiae; and the fermentation bacterium fluid and the fermentation base material are mixed in a weight ratio of (0.5-1.0) to 1000. The biological fermentation feed for the abalones provided by the invention can improve survival rate and growth efficiency of abalones, effectively replace antibiotics and reduce drug use, thereby improving quality of theabalones while purifying water and inhibiting vibrio so as to inhibit abalone infection; and thus, the feed is beneficial to ecological healthy culture.

Description

technical field

[0001] The invention relates to the field of biological feed, and specifically provides a biologically fermented abalone feed and a preparation method and application thereof. Background technique

[0002] Abalone has extremely high nutritional value, and abalone farming has now become an important part of Chinese aquaculture. China's abalone industry has experienced the evolution from luxury consumption to mass consumption, and China has become the world's largest abalone producer. The abalone product market is showing a development trend of oversupply. The variety and production capacity of abalone are no longer the main bottlenecks restricting the development of the abalone industry. The pursuit of high quality is currently the most urgent task facing the abalone farming industry. The current abalone farming industry has the following problems:

[0003] 1. The use of antibiotics cannot be avoided in abalone farming;

[0004] 2. Traditional seaweed and k...
