Compound feed for sciaenops ocellatus
[technical field]
The present invention relates to a kind of feed, relate in particular to a kind of compound feed for sciaenops ocellatus.
[background technology]
U.S. snapper is commonly called as sciaenops ocellatus, for wide salt, wide temperature, anadromous fish, is distributed in the South Atlantic Ocean and the Gulf of Mexico stretch of coastal water.Introduce China in 1991, and carry out breeding, breed.U.S.'s snapper premunition is strong, grow up fast, survival rate is high, lower oxygen concentration resistance again, is fit to very much highdensity breed, and this fish is nutritious, and meat is splendid, and look is distinguished the flavor of sweet in vain, and steam, smoke and roast is fried, closes all that it is suitable, liked by consumers in general.The aquaculture of U.S. snapper becomes a kind of industry of emerging development, and it is particularly urgent that the development of compound feed for sciaenops ocellatus also becomes.Seldom there is compound feed for sciaenops ocellatus to sell in the market; The raiser replaces with other marine fish feeds the breed of U.S. snapper is many; Or the iced trash fish of throwing something and feeding, this has caused the serious wasting of resources and environmental pollution, also makes U.S. snapper can not absorb reasonable sufficient nutrition composition; Can not bring into play its good growth performance, direct losses raiser's economic benefit.Therefore, the raiser needs a kind of reasonable mixture ratio, and is balanced in nutrition, can satisfy the long mixed feed of American Red sashimi (raw fish).
[summary of the invention]
To the problems referred to above, the purpose of this invention is to provide a kind of reasonable mixture ratio, balanced in nutrition, can satisfy the long mixed feed of American Red sashimi (raw fish).
For realizing above-mentioned purpose, the technical scheme that the present invention taked is following:
A kind of compound feed for sciaenops ocellatus is made up of the raw material of following mass percent: steam fish meal 8-12%, domestic fish meal 12-15%, fermented bean dregs 3-5%; Big dregs of beans 20-25%, peanut meal 3-5%, corn 8-12%, rapeseed dregs 8-10%; Strong flour 12-15%, blood meal 1-2%, soybean lecithin 1-2%, ocean fish oil 1-2%; Calcium dihydrogen phosphate 0.5-1%, composite mineral matter 0.5-1%, B B-complex 0.5-1%.
Preferably, form: steam fish meal 10%, domestic fish meal 14%, fermented bean dregs 5% by the raw material of following mass percent; Big dregs of beans 25%, peanut meal 5%, corn 10%, rapeseed dregs 8%; Strong flour 14%, blood meal 2%, soybean lecithin 2%, ocean fish oil 2%; Calcium dihydrogen phosphate 1%, composite mineral matter 1%, B B-complex 1%.
Wherein, composite mineral matter and B B-complex can be selected commercially available composite mineral matter and B B-complex, also can be by weight getting 49g MgSO
47H
2O, 0.7g CuSO
4H
2O, 35g FeSO
47H
2O, 0.58g CoCl
26H
2O, 2.5g MnSO

2O, 0.06g Na
2SeO
3, 2.1g ZnSO
4H
2O, 0.06g KI, the 910g zeolite powder, mixing and stirring is processed the 1000g composite mineral matter; By weight getting 2.4 * 107IU vitamin D, 1.1 * 107IU vitamin A, 10.28g vitamin E, 0.5g vitamin K; 0.19g biotin, 0.5g folic acid, 22g inositol, 1.5g nicotinic acid; 4.5g calcium pantothenate, 63g vitamin C, 5g vitamin B1,15g vitamin B2; 3.3g vitamin B6, the thin wheat skin of 870g, mixing and stirring is processed the 1000g B B-complex.
The compound feed for sciaenops ocellatus of the present invention prescription, not only comprehensive nutrition, promote growth, and can enhance immunity power, anti-stress ability; Can protect fish body enteron aisle, prevent that disease from taking place, feed coefficient is low, and digestibility is high; The good stability of feed in water is difficult for polluting breeding water body water quality.
[specific embodiment]
Take by weighing steam fish meal 10kg respectively, domestic fish meal 14kg, fermented bean dregs 5kg, big dregs of beans 25kg, peanut meal 5kg; Corn 10kg, rapeseed dregs 8kg, Strong flour 14kg, blood meal 2kg; Soybean lecithin 2kg, dihydrogen sulfate calcium 1kg, composite mineral matter 1kg, B B-complex 1kg.With crossing 80 purpose screen clothes after these raw material pulverizing, mix, granulate through conventional expanded pellet diet production line, the outer spraying in the back ocean fish oil 2kg that granulates promptly obtains compound feed for sciaenops ocellatus of the present invention.
Wherein composite mineral matter is by weight getting 49g MgSO

2O, 0.06g KI, the 910g zeolite powder, mixing and stirring is processed the 1000g composite mineral matter; By weight getting 2.4 * 107IU vitamin D, 1.1 * 107IU vitamin A, 10.28g vitamin E, 0.5g vitamin K; 0.19g biotin, 0.5g folic acid, 22g inositol, 1.5g nicotinic acid; 4.5g calcium pantothenate, 63g vitamin C, 5g vitamin B1,15g vitamin B2; 3.3g vitamin B6, the thin wheat skin of 870g, mixing and stirring is processed the 1000g B B-complex.
Carried out 12 months by a definite date American Red fish culture test in July, 2008 in national 863 sea-farming seed engineerings bases, south (Zhanjiang Evergreen Southern Ocean Technology Co., Ltd.).Result of the test shows, use feed of the present invention after, the U.S. snapper prelarva of 50g cultures that weight average reaches 1.2kg after 12 months, feed coefficient is below 1.5.
Prove that through culture experiment compound feed for sciaenops ocellatus of the present invention can satisfy its nutritional need, growth is rapid, and feed conversion rate is high, and culture benefit is obvious.Use this feed to culture U.S. snapper and can obviously strengthen its immunity function and anti-stress ability, U.S.'s snapper vigor of breed is good, and body colour is bright-coloured, and survival rate is high.Simultaneously, the U.S. snapper that the U.S. snapper of using this feed to culture is cultured than other marine fish feeds of use, its nitrogen, phosphorus excretion rate can reduce 10%-15%, pollute little to breeding water body.
