Feed additive capable of improving flesh quality and flavor of venerupis philippinarum and preparation method thereof

Abstract

The invention discloses a feed additive capable of improving flesh quality and flavor of venerupis philippinarum and a preparation method thereof. The feed additive is prepared from the following raw materials: root of twelve stamen melastoma, calystegia hederacea, eucommia ulmoides, lucid ganoderma, marshy betony herb, bambooleaf fig herb, the fruit of Chinese magnoliavine, menyanthes trifoliate, liquorice, denseflower bulbophyllum herb, fructus piperis longi, Chinese yam, plantain herb, youngia japonica, polygonum bistorta, capsella bursa-pastoris, radix pseudostellariae and oriental grape roots. The feed additive disclosed by the invention has the beneficial effects that the feed additive not only can meet the nutritional requirements of venerupis philippinarum, but also can obviously improve the flesh microstructures, is less in water pollution, and is capable of promoting emission of harmful wastes and improving the growth speed, fresh flesh yield, palatability and delicious degree of venerupis philippinarum; raw materials are natural products, so that the feed additive has the advantages of high safety, no drug residue and toxic and side effects, and the like.

Description

technical field [0001] The invention relates to a feed additive for clams, in particular to a feed additive for improving the meat quality and flavor of clams and a preparation method thereof. Background technique [0002] Clam is a common tidal flat cultured shellfish, which is widely distributed in the north and south sea areas of China. It grows rapidly, has a short breeding cycle, strong adaptability (wide temperature, wide salt, wide distribution), and long survival time out of water. It is a suitable It is an excellent shellfish cultivated in artificial high density and is one of the four major cultured shellfish in China. [0003] Clams have high nutritional value, containing 10% protein, 1.2% fat, 2.5% carbohydrates, and rich in nutrients such as phosphorus, calcium, iron, vitamins, and various amino acids. At the same time, it has high therapeutic and medicinal value. "Compendium of Materia Medica" records that it can cure diseases such as "sores, furuncles, swo...

AI Technical Summary

Problems solved by technology

Due to the particularity of the clam's bait requirements and the particularity of the feeding method, the current artificial breeding mode mainly meets the feed requirements of the clam by cultivating algae in the culture pond. Therefore, under the limitation of the natural fish productivity, the clam The growth rate of clams is slow, the yield per mu is relatively low, and the production efficiency cannot be improved

At present, there is no feed additive specifically for clams on the market, but common aquatic animal feed additives cannot meet the growth needs of clams. Nutrients cannot be absorbed by flower clams, causing water pollution and causing large-scale death of flower clams

[0005] In addition, the existing commercial feed contains a variety of hormone substances, resulting in drug residues in the clam body, and its meat taste is also greatly affected. In order to improve the nutritional value and taste of the clam, the use of hormone drugs should be avoided At the same time, feed additives with balanced and comprehensive nutrition should be prepared to promote the growth rate and fresh meat rate of clams
