Problems solved by technology

In the current rotifer farming, there are problems of low rotifer density, low yield, weak constitution, and unstable survival rate. The excess of a single nutrient will also cause eutrophication of the water body, which will further aggravate this series of problems.
At present, rotifers are mainly cultivated with livestock and poultry manure. The use of livestock and poultry manure in water will not only damage the water quality, but may also cause some diseases of farmed animals during the breeding process.
As far as biological feed is concerned, the current biologically fermented feed generally has the problems of easy contamination of bacteria and unstable quality

Abstract

The invention relates to the field of biological feeds, and particularly provides a rotifer biological fermentation feed as well as a preparation method and application thereof. The rotifer biologicalfermentation feed comprises a fermentation base material and fermentation bacteria liquid, wherein the fermentation base material comprises the following raw materials in parts by weight: 20-30 partsof corn, 15-25 parts of soybean meal, 20-30 parts of wheat bran, 8-12 parts of stone powder, 2-4 parts of monocalcium phosphate and 0.15-0.25 part of compound enzyme; and the fermentation bacteria liquid is formed by expanding propagation of composite fermentation strains including bacillus licheniformis, lactobacillus acidophilus, bifidobacterium, pediococcus pentosaceus, candida utilis and saccharomyces cerevisiae; The weight ratio of the composite fermentation strains to the fermentation base material is (0.5-1.0): 1000. According to the rotifer biological fermentation feed, the problems of low rotifer cultivation density and low yield can be solved, and the rotifer yield is increased. The physique of rotifers can be improved, the rotifer emergence rate and survival rate are increased,and the rotifer quality is improved. Water can be purified, and benign circulation of aquaculture water is facilitated.

Description

technical field [0001] The invention relates to the field of biological feed, and specifically provides a rotifer biological fermentation feed and a preparation method and application thereof. Background technique [0002] Rotifer has the advantages of short life cycle, strong reproductive ability, long-term preservation of dormant eggs, and hatching at any time. Therefore, it has become a high-quality microbiological bait for artificial breeding of fish, shrimp, and crabs. The current rotifer farming has the problems of low rotifer density, low yield, weak constitution, and unstable survival rate. Excess of a single nutrient will also cause eutrophication of the water body, further aggravating this series of problems. At present, rotifers are mainly cultivated with livestock and poultry manure. The use of livestock and poultry manure in water will not only damage the water quality, but may also cause some diseases of farmed animals during the breeding process. As far as bi...
