Abstract

The invention discloses a method for improving the streptococcus iniae infection-resisting capacity of GIFT oreochromis niloticus during high-temperature stress. The method comprises the following steps: preparing basic ration and a compound Chinese medicinal herb formula, and feeding feed. Due to the adoption of the method, the immunity index of the GIFT oreochromis niloticus during high-temperature stress can be effectively increased, the liver damage is reduced, meanwhile, the streptococcus iniae infection-resisting capacity of the GIFT oreochromis niloticus can be improved, the morbidity is reduced, and the survival rate of the GIFT oreochromis niloticus infected with streptococcus iniae can be increased. Several Chinese medicinal herbs involved in the method are relatively available and relatively low in cost; a production technology is simple. The basic ration with the compound Chinese medicinal herbs has relatively good palatability, and after the basic ration is taken by the GIFT oreochromis niloticus, drug residues in bodies of the GIFT oreochromis niloticus are relatively few, and therefore, the GIFT oreochromis niloticus meets the requirements on green healthy aquatic products.

Description

technical field

[0001] The invention belongs to feed formulation technology for aquaculture, and specifically relates to a feed preparation and feeding method that can improve the ability of Gifu tilapia to resist Streptococcus iniae infection under high temperature stress. Background technique

[0002] Streptococcus is widely distributed in nature, ubiquitous in water, animal body surface, genitourinary tract and emulsion, and is pathogenic to mammals, reptiles, amphibians and fish, and is a human-animal-fish Comorbid pathogens have caused serious economic losses to the livestock and aquaculture industries.

[0003] The optimum growth temperature for streptococcus is 33°C-37°C, therefore, streptococcal disease is very easy to break out in the environment of high temperature in summer. Tilapia is a subtropical fish with a suitable growth temperature of 29-32°C. In recent years, with the intensification of global warming, the water temperature reaches 35°C-37°C during the h...
