Granular feed for megalobrama amblycephala parent fish and preparation method thereof

Abstract

The invention relates to a granular feed for megalobrama amblycephala parent fish and a preparation method thereof. The granular feed for parent fish comprises the following raw material components: fish meal, squid meal, bean pulp, rapeseed meal, cottonseed meal, common flour, wheat middling, washed rice bran, fish oil, linseed oil, vitamin additive, mineral substance additive, monocalcium phosphate, 50% choline chloride, zeolite powder, granulesten powder, 50% vitamin E and potassium sorbate mildewproof agent. The preparation method comprises the following steps: coarsely smashing fish meal, the squid meal, the bean pulp, the rapeseed meal, the cottonseed meal, the common flour, the wheat middling, the rice peel and the potassium sorbate mildewproof agent into mixed coarse material, andscreening by a screen of 10-20 meshes; then, stirring and comptely mixing the mixed coarse material, fish oil, the linseed oil, the granulesten powder, 50% vitamin E, premix for fish, the vitamin E, the zeolite powder and the monocalcium phosphate to obtain mixed material; finely smashing the mixed material and screening by a screen of 40-60 meshes; and finally, pelletizing, drying, cooling and packaging. The granular feed has the functions of improving the reproductive capacity and disease-resistant capability of the megalobrama amblycephala parent fish.

Description

technical field [0001] The invention relates to a group head bream broodstock pellet feed and a preparation method thereof, and belongs to the technical field of aquatic compound feed. Background technique [0002] bream ( Megalobrama amblycephala ), belonging to the class Teleost, Cypriniformes, Cyprinidae, Bream subfamily, Bream genus, and is now one of the main freshwater aquaculture species in my country. In the past 20 years, more than 20 provinces, municipalities, and autonomous regions in the country have introduced and cultured bream. At present, the output of bream in the south accounts for more than 10% of the total output, and it has become the main species of pond and cage culture in my country. The benefits are significant. Feed nutrition for broodstock of pomace bream has an important impact on the number of eggs laid, the quality of eggs and larvae, the growth and survival rate of larvae and juveniles. The quality of the broodstock directly affects the quali...

Problems solved by technology

The traditional breeding of broodstock of bream is usually fed with raw materials such as fertilizer, water and soy milk. The nutrition is unbalanced, the feed is wasted, and it is easy to pollute the water body, resulting in less spawning of broodstock, low reproduction rate, and low survival rate of fry, which is not conducive to the industry of bream. healthy development of
