Feed additive capable of preventing and treating black gill disease of lobsters

Abstract

The invention mainly relates to the technical filed of breeding, and specifically discloses a feed additive capable of preventing and treating black gill disease of lobsters. The feed additive capable of preventing and treating the black gill disease of the lobsters is prepared from the following raw materials: rice bran, fresh gingers, garlic, peppers, spilanthes callimorpha, bark of ehretia dicksonii Hance, Chinese alangium root, mappia foetida, Korean pine leaves, mountain peach stem bark, birch bark, mixed enzymes, wine yeast, and acetobacter. The raw materials are rich and balanced in nutrition, and thus, the prepared feed additive is high in disease resistance, and capable of enhancing stress resistance of the lobsters as well as reducing disease incidence. Black gill disease incidence of the lobsters fed with the feed additive is reduced by 6.7% so that usage of antibiotics and disinfectants are reduced, and thus, the breeding cost is saved so as to increase income of the farmers by 12.4%. The wine yeast is inoculated into the rice bran so as to produce mellow aroma; moreover, gradual increase of alcohol is capable of promoting extraction of beneficial compositions from the rice bran so as to turn waste rice bran into treasure, and thus, nutrients of the additive are increased. The prepared feed additive is capable of promoting absorption of the lobsters, enhancing disease resistance of the lobsters and reducing disease incidence.

Description

technical field [0001] The invention mainly relates to the field of breeding technology, in particular to a feed additive for preventing and treating lobster black gill disease. Background technique [0002] Lobster black gill disease is caused by the deterioration of water quality and pollution, which prompts Fusarium to multiply and parasitize on the gill filaments, body walls, appendage bases or eyeballs of lobsters. The gills of crayfish first change from reddish to brown or light brown, and then gradually It turns black, causing the gills to atrophy, and the function gradually degenerates. The diseased shrimp often emerges from the water or attaches to aquatic plants to emerge from the water, moves slowly and sluggishly, and finally dies due to difficulty in breathing. At present, in the cultivation process of lobsters, disinfectants such as potassium permanganate or bleaching powder are used to disinfect the water body after black gill disease occurs, which can produce...

Problems solved by technology

At present, in the cultivation process of lobsters, disinfectants such as potassium permanganate or bleaching powder are used to disinfect the water body after black gill disease occurs, which can produce certain effects, but the effect is not obvious, and after the disinfectants remain in the body of the lobster, it is harmful to the environment. The human body will also cause great harm, so there is a need for a feed additive for preventing and treating crayfish plague
