Description

Compound probiotic preparation for preventing and treating gibelism hemorrhagic disease of carassius auratus gibelio and preparation method thereof
Technical Field
The invention belongs to the technical field of fishing biological products in animal and maintenance industries, and particularly relates to a compound probiotic preparation for preventing and treating gibelism of carassius auratus gibelio and a preparation method thereof.
Background
Carassius auratus gibelio is a new Carassius auratus breeding variety which is developed by inducing eggs of triploid Carassius auratus gibelio to perform gynogenesis by utilizing triploid fang zheng silver crucian (female parent) and diploid Xingguo red carp (male parent) through an artificial hybridization method. The variety has the characteristics of strong adaptability, high survival rate, high growth speed, short feeding period and the like, and particularly achieves great success in popularization and cultivation in Subei areas of Jiangsu province. However, in recent years, the carassius auratus gibelio breeding industry is severely restricted by diseases (such as carassius auratus herpesvirus disease, bacterial septicemia and myxosporidiosis) frequently, and the economic loss caused by the diseases is about 30 billion yuan each year. In order to prevent and control the spread of diseases, farmers add a large amount of chemical drugs such as antibiotics and the like into the feed, so that the drug resistance of the fish body is increased, and the drug residue of the finished fish is serious. Therefore, the development of the green, environment-friendly and safe immunity-enhanced compound feed for improving the self immunity of the carassius auratus gibelio has great significance for improving the disease resistance of the carassius auratus gibelio.
The Poly β -hydroxybutyrate (Poly- β -hydroxybutyate, PHB) is a short-chain fatty acid polymer which is generated by a bacterium in order to maintain the intracellular and extracellular osmotic pressure and accumulated in a large amount when the proportion of carbon and nitrogen in the environment is unbalanced, the short-chain fatty acid polymer generally exists in a particle state, can be degraded into β -hydroxybutyrate monomer in the intestinal tract of an animal in a chemical hydrolysis or enzymolysis mode, and is firstly found to be in bacillus megaterium.
In some researches on cultivation of fin fishes and shellfishes and the like, the results show that the probiotics are a feed additive beneficial to the growth performance, intestinal microbiota, immunity and disease resistance of aquatic animals. As with similar effects of other immunopotentiators in aquaculture, researchers have demonstrated the use of probiotics to enhance immune responses, resist disease and reduce malformations in carp species. When the fish is fed with a bait rich in Aeromonas veronii, Vibrio and Flavobacterium, both humoral immunity and cellular immune response are improved. It has been demonstrated that bacillus circulans PB7 enhances the innate immune response of carp and increases phagocytic activity after challenge with the fish pathogen aeromonas hydrophila.

The invention also comprises a preparation method of the carassius auratus gibelio immune enhancement type compound feed. The invention is helpful for enhancing the disease resistance of carassius auratus gibelio. The invention has obvious synergistic effect, the weight gain rate of fish bodies is obviously improved after the use, the indexes of ammonia nitrogen content and the like in water bodies are obviously reduced, but the purslane has the effect of preventing and treating diseases in the invention, but the preparation cost of the purslane powder is high and the efficiency is low, a vacuum microwave drying method is required, fresh purslane is intermittently dried to constant weight in a microwave vacuum low-temperature heating furnace under the conditions of 1000W and 0.08MPa of vacuum degree, the purslane is taken out and crushed and passes through a 80-mesh screen for standby, and the Yucca and the purslane are used as Chinese herbal medicines, so the invention has the defect of higher cost, and the prior art is slightly insufficient.
