A kind of Pelteobagrus fulvidraco body colour consolidates premix compound special

Technical field

The present invention relates to aquatic feeds technical field, particularly a kind of Pelteobagrus fulvidraco body colour consolidates premix compound special.

Background technology

Pelteobagrus fulvidraco is subordinate to SILURIFORMES on taxology, and have another name called Huang Lading, loud, high-pitched sound serratd edge, yellowfin fish, yellow sharp, in China, each large water system all has distribution, particularly more concentrated in the lake of the middle and lower reach of Yangtze River.This fish amino acid content enriches, fine and tender taste, delicious flavour, be of high nutritive value, sting without between flesh, and there is tonic effect and medical value, therefore economic worth is higher, rivers amount of fishing has been difficult to meet the need of market in recent years, and Pelteobagrus fulvidraco has become the focus of cultivation system, has become one of Main Commercial Fishes of China's freshwater aquiculture.According to China Fisheries statistical yearbook report, the national total output of Pelteobagrus fulvidraco in 2010 reaches 18.43 ten thousand tons, and in national freshwater aquiculture total output, accounted for 1%, culturing area mainly concentrates on Central China, East China, South China.

At present, along with agalactous universal, people feed Pelteobagrus fulvidraco with mixed feed.By vitamin and micro-and functional feedstuff additive reasonable disposition, form core premix, will effectively improve Feed Manufacturing efficiency and Usage parameter control.

Summary of the invention

The object of the invention is to, provide one to have strong antioxidant action and pigmentation, be conducive to consolidating body colour beautiful for the deficiencies in the prior art, the Pelteobagrus fulvidraco body colour improving efficiency of feed utilization consolidates premix compound special.

To achieve these goals, the technical solution adopted in the present invention is as follows: a kind of Pelteobagrus fulvidraco body colour consolidates premix compound special, comprising: trace element 12 ~ 15%, vitamin 2 ~ 4%, mineral matter 25 ~ 50%, courage salts substances 7 ~ 12%, spirulina powder 30 ~ 40%, 2% lutein 5 ~ 10%, flour 10 ~ 20%.

Described courage salts substances adopts 20% bile acid.

Described mineral matter is calcium dihydrogen phosphate.

This Pelteobagrus fulvidraco body colour consolidates the preparation method of premix compound special, and concrete steps are as follows:

(1) all material, through coarse crushing, makes the mixture of 95% reach 40 orders;

(2) material after sieving is entered mixer, rotating speed controls at 15-20 rev/min, and mixing 8-10 minute can be stand-by.

Beneficial effect of the present invention is, this Pelteobagrus fulvidraco body colour is consolidated premix compound special and contained multivitamin, meets needed for yellow catfish growing, can not produce the Pelteobagrus fulvidraco body colour change caused due to hypovitaminosis, make fish body colour keep natural colour; Add spirulina and lutein etc. and be rich in carotenoid material, there is strong antioxidant action and pigmentation, be conducive to consolidating body colour beautiful, improve efficiency of feed utilization.
