Health-care-type puffed compound feed for yellow catfishes and preparation method thereof

Abstract

The invention discloses a health-care-type puffed compound feed for yellow catfishes and a preparation method thereof. The feed comprises natural pigments and health-care components, wherein the natural pigments comprise cape jasmine fruit powder, Ningxia wolfberry fruit residues, all grass of planis corepsis powder and corn protein powder; and the health-care components comprise pine needle powder, cape jasmine fruit powder, Ningxia wolfberry fruit residues, all grass of planis corepsis powder and baikal skullcap roots. The feed solves the problem of keeping the body color of the yellow catfishes close to a natural body color and improving the immunity and the disease resistance of the yellow catfishes without the addition of artificial extracting pigment, and the feed can effectively reduce the incidence of hemorrhagic edema disease, split head disease and enteritis, and improve the survival rate of fry, has the effects of promoting growth, and can effectively reduce the feed coefficient of the yellow catfishes and improve culturing benefits.
