Compound feed for incubation period of clam worm and preparation method thereof

The invention discloses a compound feed for the incubation period of clam worm and a preparation method thereof. The compound feed is prepared by performing crushing, mixing, tempering aging, puffing granulating and drying on the following raw materials in part by weight: 25 to 40 parts of white fish meal, 15 to 30 parts of soya bean meal, 10 to 15 parts of high-gluten flour, 5 to 15 parts of alpha-starch, 2 to 5 parts of scallop powder, 2 to 5 parts of squid liver powder, 2 to 5 parts of shrimp shell meal, 2 to 5 parts of beer yeast, 3 to 5 parts of fish oil, 1 to 2 parts of soy lecithin, 1 to 2 parts of composite mineral salt, 0.5 to 1 part of multivitamin, 0.2 to 0.5 part of probiotics and 0.05 to 0.1 part of ethoxyquin. The compound feed is high in protein content and fat content, reasonable in raw material component compatibility, high in palatability, high in conversion rate, high in stability, low in dissolve-loss ratio and simple in preparation method and process, can be soaked in water for a long time, and has easiness in large-scale production and a remarkable effect on improving clam worm culture efficiency; the contained nutritional components can meet the requirement on the growth in the incubation period of the clam worm.
