Abstract

The invention discloses a feed for grass carps. The feed consists of the following raw materials in part by weight: 20 to 30 parts of protein source, 15 to 25 parts of energy source, 0.5 to 2 parts of compound vitamin, 2 to 6 parts of calcium hydrophosphate, 0.5 to 1 part of common salt and 5 to 15 parts of bonding agent, wherein the protein source may be one or a mixture of more of fish meal, bean pulp, cottonseed meal and rapeseed meal; the energy source may be one or a mixture of more of rice grain, corn, defatted rice bran and wheat bran; and the bonding agent may be bentonite, algae, alpha-starch, sodium polyacrylate or poly propenyl alcohol. The feed for grass carps has the advantages that the feed is manually prepared and is the complete feed which can meet various nutritional demands of grass carps, and the nutritional matters contained in the feed include protein, energy, vitamins, minerals and the like which are all necessary for grass carps, so that an aim of promoting the growth of grass carps is achieved.

Description

A kind of feed of grass carp

Technical field

The present invention relates to a kind of fish meal, be specifically related to a kind of feed of grass carp.

Background technology

Grass carp, the rear portion is flat-sided, the look bluish yellow, the head breadth is flat, kisses little, and mouthful end position need not.The pharynx comb shape, two row sharp teeth, are apt to sting grass blade, be a kind of typical herbivorous fishes.Its intestines are longer, are four or five times of body length.Grass carp is one of principal item of China's freshwater aquiculture, and all parts of the country culturing, are typically to eat the vegetalitas fish nearly all.In natural waters, be food mainly with pasture and water and other plant.

At present, popularizing along with agalactous, all is to be main feeding method with mixed feed; But the nutrition in the batching is not quite reasonable; This is very unfavorable to the grass carp growth, therefore needs a kind of reasonable mixture ratio, all more uniform high-quality particle of various nutrition fish meal.

Summary of the invention

The objective of the invention is provides a kind of feed of grass carp of various nutrition reasonable mixture ratio for overcoming the deficiency of above-mentioned prior art.

For realizing above-mentioned purpose, the present invention adopts following technical proposals:

A kind of feed of grass carp, it is made up of following substances in parts by weight: protein sources 20-30 part, energy source 15-25 part, B B-complex 0.5-2 part, calcium monohydrogen phosphate 2-6 part, salt 0.5-1 part, adhesive 5-15 part.

Said protein sources is selected from one or more the mixing in fish meal, dregs of beans, the cottonseed dregs of rice and the rapeseed dregs.

The mixing of one or more in said paddy, corn, defatted rice bran, the wheat bran.

Said adhesive is bentonite, marine alga, alphalise starch, Sodium Polyacrylate or POLYPROPYLENE GLYCOL.

The fish meal comprehensive nutrition, trophic component fundamental sum fish body is formed similar, thereby utilization rate is high.It is a kind of ideal protein source.But fish meal costs an arm and a leg, and quality is unstable, has limited its a large amount of interpolations.The cottonseed dregs of rice, rapeseed dregs protein content also higher (33%), the grass carp happiness is searched for food, and is also more satisfactory to its digestive utilization ratio.Contain ANFs in the cotton rapeseed dregs, in nonruminant, can not fully add.And use feed as fishing, and can directly using without any need for handling again, the therefore preferred cottonseed dregs of rice, rapeseed dregs are the cheap protein sources of grass carp.

The maximum difference aspect mineral metabolism of fishes and shrimps and livestock and poultry is fish physical efficiency absorption portion inorganic salts from water, can effectively utilize the calcium in the water like fish, and the calcium in the feed is just not as important in the animal and fowl fodder.Phosphorus content is low in the fresh water, and therefore, fishes and shrimps need be considerably beyond calcium to phosphorus.Grass carp is 0.85-1% to the requirement of available phosphorus.

Binder and phagostimulant are two kinds of the most frequently used in the aquatic feeds non-nourishing additive agents.Because particulate material must keep a period of time in water, reduce dissolve-loss ratio, could fully be searched for food by fishes and shrimps, prevent water quality deterioration simultaneously.Therefore it is very necessary to add binder.Bentonite, marine alga, alphalise starch, Sodium Polyacrylate, POLYPROPYLENE GLYCOL etc. all are binders preferably.The selection of binder not only will be considered the influence of its viscosity to granulating, and goes back its palatability of considered, security and nutritional labeling etc.

The invention has the beneficial effects as follows; The i.e. artificial preparation of the feed of this prescription, complete feed, the nutriment that can satisfy the various nutriment demands of grass carp comprise the albumen of grass carp needs, energy; Multiple composition such as vitamin and mineral matter is from promoting to reach the effect of fish growth.

The specific embodiment

Through instantiation the present invention is further set forth below, should be noted that following explanation only is in order to explain the present invention, its content not to be limited.

Embodiment 1

A kind of feed of grass carp; It is made up of following substances in parts by weight: 10 parts of dregs of beans, 15 parts of the cottonseed dregs of rice, 15 parts of paddy, 5 parts in wheat bran, adopt commercially available fish with 1 part of B B-complex premix, 3 parts of calcium monohydrogen phosphates, 0.5 part of salt, 6 parts of alphalise starch alphalise starch.

The above-mentioned raw materials mixed preparing is formed.

Embodiment 2

A kind of feed of grass carp; It is made up of following substances in parts by weight: 15 parts of the cottonseed dregs of rice, 15 parts of rapeseed dregs, energy source corn 10,10 parts in wheat bran, adopt commercially available fish with 0.5 part of B B-complex premix, 2 parts of calcium monohydrogen phosphates, 0.8 part of salt, 10 parts of adhesive Sodium Polyacrylates.

The above-mentioned raw materials mixed preparing is formed.
