Abstract
A compound immunoenhancer for larvae and juvenile of tilapia comprises the following components by weight percent: beta-glucan 20-30, ginsenoside 5-10, seaweed polysaccharides 10-20, phospholipids 5-10, vitamin C-2-polyphosphate ester 20-30, vitamin E 10-15, digestive enzyme 5-10 and citric acid 5-10. The compound immunoenhancer obviously strengthens the immunity of the larvae and juvenile of the tilapia and increases the survival rate, the activities and growth speed of the larvae and juvenile of the tilapia; the compound immunoenhancer is used as a feed additive in the feed of the larvae and juvenile of the tilapia, with additive dosage of only 0.2-0.3%, which has no adverse effect on the feed palatability. The used raw materials enjoy stable sources, low price and simple production technology.
Description
Technical field
The present invention relates to a kind of hybrid tilapia fish larvae composite immune reinforcing agent.
Background technology
Tilapia mossambica is that Perciformes Callichthyidae Tilapia mossambica belongs to, and belongs to the tropical fish, has kind more than 100, and majority originates in Africa.Tilapia mossambica has grow fast, characteristics such as feeding habits are wide, reproductive capacity is strong, disease is few, meat is good, output height.The principal item of culturing has at present: more than 10 kinds such as Sarotherodon sp, lucky good fortune Tilapia mossambica, lucky Tilapia mossambica difficult to understand.Sarotherodon sp is the offspring of Oreochromis aureus and bolti hybridization, is the main at present Tilapia mossambica kind of culturing of China.It is regional wide that the suitable Tilapia mossambica in coastal areas of southern China area is cultured, and Tilapia mossambica is cultured has huge potentiality to be exploited and advantage.
Tilapia mossambica is mouthful incubating property fish, and hatching has following shortcoming naturally: brooding time is long, the parent population growth retardation, and reproductive capacity descends; The fry hatching rate is low, and survival rate is low, and regularity is poor.Some advanced persons' the factory of growing seedlings has begun to adopt the mode of artificial incubation for this reason.Artificial incubation will relate to the cultivation of fry, in cultivation, only rely on the biological feed of throwing something and feeding to guarantee growing of young postlarva, must need and meet the young postlarva perfect compound feed of feature that grows, but the perfect compound feed at hybrid tilapia fish larvae is not arranged in the market as yet.And because the systematic growth imperfection of young postlarva, its degree that absorbs to feed is lower, causes young postlarva of Tilapia resistance poor, hypoimmunity.Therefore, be necessary to improve the disease-resistant anti-adversity ability of young postlarva, improve its utilization, improving its speed of growth, thereby improve survival rate and the vigor of young postlarva feed by the form of feed addictive.
Summary of the invention
The object of the invention provides a kind of hybrid tilapia fish larvae composite immune reinforcing agent, and it can overcome above-mentioned defective.
Its component of the present invention and percetage by weight scope are respectively: beta glucan 20-30; Ginsenoside, 5-10; Algal polysaccharides, 10-20; Phosphatidase 15-10; Vitamin C-2-polyphosphate 20-30; Vitamin E 10-15; Digestive ferment 5-10; Citric acid 5-10.
The present invention has following advantage: (1) has obviously strengthened the immunity of organisms of hybrid tilapia fish larvae, improves survival rate; (2) obviously improve the hybrid tilapia fish larvae activity and the speed of growth; (3) use in the young postlarva of Tilapia feed as feed addictive, additive capacity only is 0.2-0.3%; (4) the present invention does not have any harmful effect to the feed palatability; (5) its raw material source of the present invention is stable, cheap, and production technology is simple.
The specific embodiment
Take by weighing 30kg beta glucan, 5kg ginsenoside, the 10kg algal polysaccharides, 10kg phosphatide, 20kg vitamin C-2-polyphosphate, 15kg vitamin E, 5kg digestive ferment, 5kg citric acid are hybrid tilapia fish larvae composite immune reinforcing agent of the present invention with even mixing of these 8 kinds of materials.It strengthens the resistance of the disease that bacterium and virus etc. is caused by improving the immunity of organisms of young postlarva of Tilapia.
2007-2008, experiment at Zhanjiang City, Guangdong Province and Maoming City shows, the Sarotherodon sp fry of artificial incubation uses this composite immune reinforcing agent can make the speed of growth of young postlarva improve 17.76-20.59% respectively in the complete period of growing seedlings, and survival rate improves 18.78-20.71% respectively.
Zhanjiang, Maoming hybrid tilapia fish larvae culture experiment result
