Abstract

The invention discloses a Chinese herbal feed additive for red swamp crayfish as well as a preparation method and application thereof. The feed additive contains a water extract liquid from whole flowers of perennial semi-evergreen twinning woody climbing plant honeysuckle of the Caprifoliaceae family and oligoxylose at a mass ratio of 150:1. The preparation method comprises the steps as follows:drying by adsorbing the water extract liquid of honeysuckle whole flowers with zeolite, wherein the weight ratio of water extract liquid of honeysuckle whole flowers to zeolit is 1:6.5; after drying,mixing the water extract liquid of honeysuckle whole flowers with oligoxylose at a ratio of 150:1; and mixing to obtain the feed additive. The application of the feed additive is as follows: the feedadditive is added to a red swamp crayfish feed at an additional amount of 1.5%. The Chinese herbal feed additive is low in cost and environment-friendly, can increase the utilization efficiency of nutrients in a formula feed for red swamp crayfish, and can promote growth and improve meat quality of red swamp crayfish. The preparation method can be applied to large-scale industrial production. Thefeed additive is a novel growth-promoting additive for red swamp crayfish formula feeds.

Description

technical field [0001] The invention relates to a novel Chinese herbal medicine feed additive for crayfish and an application method thereof, which belongs to the technical field of biological products and can be used as an additive in crayfish feed. Background technique [0002] Due to the aggravation of environmental pollution in my country's aquaculture industry, bacteria, viruses or parasites cause frequent acute, subacute or chronic diseases of shrimp, resulting in shrimp aquaculture production being attacked by diseases, the survival rate is reduced, and the aquaculture industry is seriously endangered. of sustainable development. The use of antibiotics or chemical drugs for prevention or treatment often brings disadvantages such as microbial resistance, drug residues in aquatic products, and pollution of the water environment, causing harm to animal health and production as well as human health. Therefore, looking for an ideal non-toxic, residue-free, high-efficiency,...
