Abstract

The invention discloses a coated feed used for a leech and capable of preventing and treating enterogastritis. The coated feed is prepared from the following raw materials by weight: 30 to 40 parts of rice bran, 5 to 6 parts of garlic, 3 to 4 parts of rapeseed oil, 20 to 24 parts of beef offal, 4 to 5 parts of fresh mycelium of straw mushroom, 2 to 3 parts of liquor, 40 to 50 parts of pig blood plasma, 5 to 8 parts of cheese, 40 to 50 parts of grain amaranth, 30 to 40 parts of tenebrio molitor, 5 to 8 parts of plasma protein powder and a proper amount of edible oil, yeast, compound sulfamethoxazole, natto strain, sodium hydroxide, chitosan and water. Protein peptide which is more easily digested and absorbed by the leech and has better physiological functions is prepared from tenebrio molitor and grain amaranth in the feed through extraction, centrifugation, fermentation, etc.; the feed has fragrant flavor and is easy to store; the leech fed with the feed is active in eating; and the feed effectively improves intestinal health of the leech, prevents and treats enterogastritis and enables the fed leech to have a low disease incidence rate and to be strong and vital.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a leech coated feed for preventing and treating gastroenteritis 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", which has been recorded in successive dynasties. 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 infarction, strok...
