Coated feed for improving intestinal function of leeches and preparation method for coated feed

Abstract

The invention discloses a coated feed for improving the intestinal function of leeches. The coated feed is prepared from the following raw materials in parts by weight: 40-50 parts of buckwheat, 15-20 parts of buds of foxtail millet, 2-3 parts of snakegourd fruit extract, 20-25 parts of clamworms, 40-50 parts of pig plasma, 5-8 parts of cheese, 40-50 parts of amaranthus hypochondriacus, 30-40 parts of tenebrio molitor, 5-8 parts of plasma protein powder and a proper amount of edible oil, saccharomycetes, bacillus natto, sodium hydroxide, chitosan and water. In the feed, protein peptide which is easily digested and absorbed by the leeches is prepared from the tenebrio molitor and amaranthus hypochondriacus through the processes such as extraction, centrifugal fermentation and the like, so that the leeches have a better physiological function; the snakegourd fruit extract has the effects of clearing heat, removing stasis, lubricating the intestines and relaxing bowl, so that the intestinal health of the leeches is improved; the buds of foxtail millet further have a good spleen-tonfying and digestion-helping effect. The feed is fragrant in flavor and easy to store and the leeches raised by the feed are long and plump.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a coating feed for improving leech intestinal function and a preparation method thereof. Background technique [0002] The use of leeches in my country is nearly a thousand years earlier than in the West. The use of leeches as a traditional Chinese medicine was first recorded in "Shen Nong's Materia Medica", and it has been recorded in successive dynasties of herbal medicines. Leech was identified as one of the 35 Chinese herbal medicines for promoting blood circulation and removing blood stasis at the National Academic Conference on Activating Blood and Removing Blood Stasis in 1986. A few micrograms of hirudin discovered and extracted by the British McWatt in the 1950s can prevent blood from coagulating. It can reduce blood viscosity, relieve arterial wall spasm, dilate blood vessels, promote blood circulation and absorb exudate. Hirudin can also be used to treat myocardial infar...
