Abstract

The invention discloses a mixed feed for fish, and relates to the technical field of feed production. The formula of the mixed feed comprises the following ingredients in mass percent: 25-40% of imported fish meal, 10-30% of bean pulp, 10-20% of rapeseed meal, 5-15% of cottonseed meal, 1-8% of wheat middling, 1-8% of soybean lecithin, 1-10% of fish oil, 0.5-2% of monocalcium phosphate, 1-5% of vitamin, and 0.5-2% of a microelement. The formula is simple, accurate, comprehensive in nutrition, good in food calling performance, good in stability in water, and easy to digest and absorb.

Description

A kind of compound feed used for fish

Technical field

The present invention relates to Feed Production Technology field, be specifically related to a kind of compound feed used for fish.

Background technology

Fish meal, as the term suggests be exactly the feed of feeding to fish.Its main component protein, fat, vitamin and mineral matter composition.Protein is the important nutrient of fishes and shrimps existence, is the important composition material forming body cell, tissue, organ.The protein that fish normal growth needs have quantity enough, easily to digest and assimilate in feed, various amino acid ligand ratio is suitable.The protein that when fish panning protein is not enough, poor growth, immunity of organisms decline, various amino acid ligand ratio is suitable.When fish panning protein is not enough, poor growth, immunity of organisms decline, tissue upgrades slowly, wound healing is poor, easily ill with joint efforts.The protein of picked-up is too much, and digestibility and utilization protein not will excrete with the form of nitrogen element, has both reduced the utilization ratio of body to protein, has increased the weight of again the pressure of water quality management, also easily cause the generation of intestines problem simultaneously.Under relatively suitable protein level condition, amino acid balance not only can make fishes and shrimps obtain the speed of growth faster, and its immunity also can strengthen to some extent.Fat especially essential fatty acid is the immunoreactive important regulatory factors of fishes and shrimps.Humoral immunity ability and cell immunocompetent that essential fatty acid can improve animal body is added in daily ration, the generation of the cellular immunity factor can be promoted, material impact is produced to the lymphproliferation response that mitosis stimulates, the phagocytic activity of macrophage can be strengthened.VC is fishes and shrimps normal growth and maintains the necessary nutriment of normal physiological function, and many fishes and shrimps can not synthesize, and must obtain from daily ration.VC reacts equal tool to the humoral immune reaction of fishes and shrimps and Nonspecific immunity and has a certain impact, thus in fishes and shrimps daily ration, add VC can strengthen it and exempt from should to react equal tool with Nonspecific immunity and have a certain impact, in fishes and shrimps daily ration, thus add VC can strengthen its immunologic function, improve its resistance against diseases and survival rate.VC is that fishes and shrimps normal immunoreaction is necessary, but it is not directly work, but has the metallic element of defensive enginery (as copper, iron) to act synergistically with some polyphenoils (as VE) with to body.VE is also the important nutriments of fishes and shrimps, and its major function is anti-oxidant, with protect fat-soluble cell membrane and unrighted acid not oxidized, in feed, appropriate interpolation as Immune-enhancing effect material, can be strengthened the phagocytosis of cell, strengthens cytophagous generation.VA is required to the immune normal function of maintenance fishes and shrimps.In feed, high-caliber VA can improve the phagocytic activity of fishes and shrimps body endolymph cell and the vigor of serum lysozyme and specific complement, thus produces material impact to fishes and shrimps immunity function.Mineral matter element is as quite important in the premunition and immune response of fishes and shrimps in elements such as iron, selenium, copper, zinc, can not lack in feed.

Although existing fish feed formula all comprises above-mentioned basal nutrient material, due to formula inaccuracy, cause the not comprehensive nutrition of feed, attractant is bad, and digests and assimilates bad, haves much room for improvement.

Summary of the invention

The object of this invention is to provide a kind of compound feed used for fish, its formula is simple, and accurately comprehensive nutrition, attractant are good, and stability in water is good, digests and assimilates.

In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its prescription quality percentage is as follows: imported fish meal 25%-40%, beans Hectometer 10%-30%, dish Hectometer 10%-20%, cotton Hectometer 5%-15%, secondary powder 1%-8%, soybean lecithin 1%-8%, fish oil 1%-10%, calcium dihydrogen phosphate 0.5%-2%, vitamin 1%-5%, micro-0.5%-2%.

The present invention should be stored in cool place, ventilation, dry place, and the shelf-life is no more than two months.

The present invention has following beneficial effect: its formula is simple, and accurately comprehensive nutrition, attractant are good, and stability in water is good, digests and assimilates.

Detailed description of the invention:

This detailed description of the invention is by the following technical solutions: its prescription quality percentage is as follows: imported fish meal 35%, beans Hectometer 20%, dish Hectometer 15%, cotton Hectometer 10%, secondary powder 5%, soybean lecithin 5%, fish oil 5%, calcium dihydrogen phosphate 1%, vitamin 3%, trace element 1%.

The using method of this detailed description of the invention: when normally feeding, throws something and feeds according to " four is fixed " principle, has full being very likely advisable with fish; Actual daily ration, feeding quantity need to live apart water temperature, water quality, climate change and fish these concrete conditions of food ration and determine.

This detailed description of the invention has following beneficial effect: its formula is simple, and accurately comprehensive nutrition, attractant are good, and stability in water is good, digests and assimilates.

The above is only in order to illustrate technical scheme of the present invention and unrestricted, other amendment that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.

Claims

1. a compound feed used for fish, is characterized in that its prescription quality percentage is as follows: imported fish meal 25%-40%, beans Hectometer 10%-30%, dish Hectometer 10%-20%, cotton Hectometer 5%-15%, secondary powder 1%-8%, soybean lecithin 1%-8%, fish oil 1%-10%, calcium dihydrogen phosphate 0.5%-2%, vitamin 1%-5%, micro-0.5%-2%.
