Embodiment Construction

[0008] From mid-to-late May to mid-June, before the high temperature, licorice, perilla leaves, houttuynia cordata, honeysuckle, isatis root, hawthorn, eucommia leaves, and astragalus are dried and crushed to make components according to a certain ratio. 100g compound Chinese herbal medicine contains 15g licorice; 5g perilla leaf; 20g houttuynia cordata; 10g honeysuckle; 15g isatidis; 15g hawthorn; 10g eucommia leaf; 10g astragalus. Weigh 20 g of the compound, put it in a casserole, add 200 mL of distilled water, decoct 3 times, each time for 30 min, combine the filtrate of the 3 times, add it to 1 kg of the basic diet and mix well to make a compound water extract containing 2% medicinal feed. The feed was made into granules with a granulator, placed in a cool place and air-dried, and stored at 4°C for later use. Carry out intensive cultivation before high temperature for about 30 days, and feed the feed according to the weight of the fish. From mid-to-late June to early Sep...

Abstract

The invention discloses a feed for improving streptococcal disease resistance of tilapia, and the feed is characterized in that: the feed is tilapia base daily ration particles containing 1% and 2% (by weight) of a compound Chinese herbal medicine water extraction solution; the compound Chinese herbal medicine water extraction solution comprises: by weight, 15% of licorice, 5% of perilla leaf, 20% of cordate houttuynia, 10% of honeysuckle flower, 15% of isatis root, 15% of hawthorn, 10% of eucommia leaf and and 10% of astragalus. Before the high temperature of the summer comes, the feed containing 2% of the compound Chinese herbal medicine water extraction solution is first fed to the tilapia for strengthening cultivation, the feed containing 1% of the compound Chinese herbal medicine water extraction solution is fed in high temperature season, the streptococcal disease infection resistant capability of the tilapia can be effectively improved, the survival rate after infection of pathogen can be increased. The Chinese herbal medicine materials in the feed are easy to obtain, are low in price, and are simple in production technology. The feed added with the compound Chinese herbal medicine has better palatability, the tilapia taking the feed may have less drug residue in the body, and the feed is in accord with requirements of green healthy aquatic products.

Description

technical field [0001] The invention belongs to the technical field of feed formula for aquaculture, and in particular relates to a compound Chinese herbal medicine feed capable of improving the anti-streptococcus infection and growth of tilapia and a feeding method thereof. Background technique [0002] Tilapia, as the main freshwater fish cultured in the southern provinces of China, plays an important role in increasing fishery economic production and increasing fishermen's income. In 2012, China's tilapia output was 1.45 million tons, basically the same as the total output of 1.44 million tons in 2011. Among them, there are reasons for the increase in breeding costs and the reduction in the amount of seedlings released, but the main reason is that intensive farming causes frequent occurrence of diseases and reduces the breeding output. The main diseases that harm tilapia are bacterial and viral diseases. The former is the most harmful. Currently more prevalent are bact...
