Embodiment 1

[0061] Example 1: Preparation of environmentally-friendly elver extruded floating pellet compound feed

[0062] Raw materials: see Table 1.

[0063] Preparation method: weigh the special grade red fish meal, special grade white fish meal, flour, peeled soybean meal, brewer's yeast, soybean oil, fish oil, soybean lecithin and compound premix feed additives;

[0064] Crushing: crushing the dehulled soybean meal in the raw material;

[0065] In addition to impurities;

[0066] The first batching and mixing: mix the special red fish meal, special white fish meal, flour, crushed dehulled soybean meal, brewer's yeast and compound premix feed additives in the mixer to make the mixing uniformity CV value less than 7%;

Abstract

The invention discloses an environment-friendly elver puffed floating granular compound feed and a preparation method of same. The feed includes, by weight, 15-30% of special grade brown fishmeal, 25-35% of special grade white fishmeal, 18-20% of flour, 5-10% of peeled soybean meal, 2-6% of brewer's yeast, 6-10% of soybean oil, 2-5% of fish oil, 1.5% of soya bean lecithin and 5% of a compound feedadditive premix. The fertilizer is prepared through a vacuum spray coating technology. The feed reduces protein level and increases fat level, so that nitrogen emission is reduced and production costis greatly reduced.

Description

Technical field [0001] The invention relates to the field of aquatic animal feed, in particular to an environmentally-friendly elver extruded floating granular compound feed and a preparation method thereof. Background technique [0002] At present, the traditional powdered feed has been used in the production of eel in our country, that is, the powdered feed is mixed with water and then fed. This method has the disadvantages of polluting water quality due to feed dissolution, inconvenience to use, high feed cost and poor individual growth uniformity of eels. In recent years, the extruded pellet feed that has emerged in the field of aquatic animal feed has the advantages of low production cost, high feed efficiency, less pollution to the aquaculture water body, and wide range of raw material sources. It is more and more widely used in aquaculture, especially in eel farming. The use of extruded floating pellet feed has more advantages: (1) Water saving, the loss rate of extruded ...
