Mixed fish feed containing feed additive and preparation method of feed

Abstract

The invention relates to the technical field of feed additives, in particular to a mixed fish feed containing a feed additive and a preparation method of the feed. The feed additive is a honeysuckle decoction residue alcohol extract powder, and the raw material is honeysuckle decoction residues which are subjected to Soxhlet extraction, and the honeysuckle decoction residues are subjected to alcohol-microwave extraction. The effective components of the honeysuckle decoction residue alcohol extract powder include 28-35 mg / g chlorogenic acid, 8-15 mg / g luteolin, 4-10 mg / g quercetin and 5-13 mg / grutin. The mixed fish feed is a mixture prepared by uniformly stirring a basic fish feed and the feed additive, and is suitable for the culturing of fishes in light eutrophic water bodies. The mass ratio of the basic fish feed and the feed additive is 1000:8 to 1000:15. The light eutrophic water bodies refer to water bodies with a comprehensive trophic state index of 50-60. The feed improves thequality of fishes in light eutrophic water bodies while improving the comprehensive utilization value of the honeysuckle decoction residues.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a mixed fish feed with feed additives and a preparation method. Background technique [0002] On the one hand, honeysuckle is a traditional Chinese herbal medicine plant resource widely distributed in my country, which mainly contains active ingredients such as organic acids, volatile oils, flavonoids, triterpenoid saponins and trace elements. Its roots, stems, leaves and flowers can be effectively used in medicines, health products and food. Traditional Chinese medicine companies produce medicinal residues every day, including a large amount of honeysuckle medicinal residues. In the past, the methods of industrial disposal of medicinal residues were mainly stacking, landfilling or incineration. Recently, it has been reported that the comprehensive utilization methods of traditional Chinese medicine dregs mainly include rough processing into cultivation materials for edib...

Problems solved by technology

Although mild eutrophication of the water body will not cause a large number of farmed fish to die, it will increase the crude fat and crude protein content in the fish meat, significantly reduce inosinic acid, umami amino acids and essential amino acids, and the ratio of saturated fatty acids and unsaturated fatty acids. The ratio is out of balance, and the lipid peroxidation product malondialdehyde is produced, thereby reducing the freshness, flavor and nutritional quality of fish meat

The main reason is that eutrophication leads to the crazy growth of toxic algae. When animals such as fish and shrimp eat these toxic algae, a large amount of toxins will accumulate directly or indirectly in the body, resulting in disordered metabolism of the fish body. Disease resistance, stress resistance and hypoxia tolerance are significantly reduced

However, currently there is a lack of feed additives that can clearly improve the quality of fish meat in mildly eutrophic water bodies

Conventional feed additives pursue high efficiency by adding antibiotics for a short period of time, not only will not improve meat quality, but long-term use will also cause fish death due to side effects of antibiotics, which is not conducive to the long-term development of aquaculture
