Description

Promote the feed of silverside gonad development

Technical field

The present invention relates to a kind of fish meal, be specifically related to a kind of feed promoting silverside gonad development.

Background technology

Silverside has another name called coho, is commercially called as salmon.Belong to Clupeiformes, Ranidae, Oncorhynchus, river property of tracing back straddling fish stocks.Silverside lays eggs in fresh water, growth, swims into sea until grow up to fingerling.After growing up to adult fish in the sea, then migration is carried out laying eggs to fresh water and completes its growth cycle.Silverside former be habitat mainly in Pacific east, that is the West Coast of America & Canada, belongs to cold water fishes.

Silverside yellowish pink is scarlet, thorn between few flesh, edible part is large, flesh quality is high, without fishy smell, matter good delicious be the first-selected fish of making raw fish, its fish-egg is the raw material of high-grade nutraceutical caviar.Containing abundant β 3 aliphatic acid, fat-soluble A and vitamin D, water-soluble (vitamin) B 12 and B6 in the flesh of fish, cholesterol level is lower, is the health food meeting modern trophic level.Due to its edibility and health value, the production of propagating artificially of silverside also gets more and more.

The egg-laying time of silverside is different because of temperature of cultivation and areal variation, and lay eggs early in the area of temperature drift, extremely frigid zones is laid eggs late.The parent population of gonadal maturation, body colour shades, and ingests less, and especially raun almost stops feed before laying eggs.

The reproduction technique of what current research was more is silverside, and feed nutrition formulating is less.

Summary of the invention

[technical problem that will solve]

The object of the invention is the problem solving above-mentioned prior art, a kind of feed promoting silverside gonad development is provided, to meet the requirement of silverside parent population to nutrition, induction feed, improve the immunity of parent population, promote gonad development, provide parent population to grow required energy.

[technical scheme]

In order to reach above-mentioned technique effect, the present invention takes following technical scheme:

Promote a feed for silverside gonad development, it is made up of the component of following weight portion:

Fish meal 34 ~ 38 parts; shrimp shell meal 3 ~ 5 parts, euphausia superba powder 3 ~ 4 parts, brewer's yeast 7 ~ 10 parts; phospholipid powder 3 ~ 5 parts; skimmed milk power 3 ~ 5 parts, 6 ~ 8 parts, flour, alphalise starch 4 ~ 6 parts; 18 ~ 22 parts, fish oil; soybean oil 3 ~ 5 parts, 3 ~ 5 parts, olive oil, vitamin C 0.5 ~ 0.7 part; vitamin E 0.4 ~ 0.6 part; salt algae powder 0.05 ~ 0.18 part, haematococcus pluvialis powder 0.04 ~ 0.15 part, n-3HUFA0.8 ~ 2.5 part; taurine 0.1 ~ 0.15 part; Choline Chloride 1.5 ~ 2.5 parts, D-VB5 calcium 0.01 ~ 0.02 part, calcium dihydrogen phosphate 1 ~ 1.5 part.

A preferred embodiment of the present invention, the feed of described promotion silverside gonad development is made up of the component of following weight portion:

Fish meal 38 parts, shrimp shell meal 3 parts, euphausia superba powder 4 parts, brewer's yeast 9 parts; phospholipid powder 4 parts, skimmed milk power 5 parts, 6 parts, flour, alphalise starch 6 parts; 20 parts, fish oil, soybean oil 5 parts, 4 parts, olive oil; vitamin C 0.7 part, vitamin E 0.4 part, salt algae powder 0.15 part; haematococcus pluvialis powder 0.15 part, n-3HUFA2.5 part, taurine 0.15 part; Choline Chloride 1.5 parts, D-VB5 calcium 0.02 part, calcium dihydrogen phosphate 1 part.

Another preferred embodiment of the present invention, the feed of described promotion silverside gonad development is made up of the component of following weight portion:

Fish meal 37 parts, shrimp shell meal 4 parts, euphausia superba powder 4 parts, brewer's yeast 10 parts; phospholipid powder 3 parts, skimmed milk power 3 parts, 8 parts, flour, alphalise starch 5 parts; 22 parts, fish oil, soybean oil 3 parts, 3 parts, olive oil; vitamin C 0.7 part, vitamin E 0.4 part, salt algae powder 0.15 part; haematococcus pluvialis powder 0.15 part, n-3HUFA2.2 part, taurine 0.12 part; Choline Chloride 2.5 parts, D-VB5 calcium 0.01 part, calcium dihydrogen phosphate 1.3 parts.

Another preferred embodiment of the present invention, the feed of described promotion silverside gonad development is made up of the component of following weight portion:

Fish meal 35 parts, shrimp shell meal 5 parts, euphausia superba powder 3.5 parts, brewer's yeast 9 parts; phospholipid powder 4 parts, skimmed milk power 3 parts, 7 parts, flour, alphalise starch 5 parts; 18 parts, fish oil, soybean oil 4 parts, 4 parts, olive oil; vitamin C 0.6 part, vitamin E 0.6 part, salt algae powder 0.18 part; haematococcus pluvialis powder 0.15 part, n-3HUFA2.5 part, taurine 0.11 part; Choline Chloride 1.5 parts, D-VB5 calcium 0.02 part, calcium dihydrogen phosphate 1.2 parts.

Parent population, refers to grow to the sexal maturity stage, has milter or the raun of fertility, also cry kind of a fish.

Salt algae powder contains the natural Beta-carotene that percentage by weight is 2% ~ 10%; The bioactivator such as unrighted acid and immune polysaccharide; The multivitamins such as higher vitamin C, vitamin E, can be used as the source of vitamin.Simultaneously also containing rich in protein, 18 seed amino acids, wherein 10 kinds is that animal body is required and can not synthesize again, comprehensive nutrition equilibrium.Can be used for aquatic livestock larva initial baits, parent is cultivated, formed and improve the fields such as animal disease resistant power, play the physiological activity of its uniqueness, to promoting that the development of aquaculture cause is of great importance.

Haematococcus pluvialis powder is the source of natural astaxanthin industry, is haematococcus pluvialis raw material pulvis, of many uses.Natural astaxanthin, due to its special structure, is the strongest antioxidant of nature discovery up to now, is described as " supper vitamin E ".Astaxanthin (Astaxanthin) is a kind of high-quality, efficient, safe colouring agent and natural, there is higher nutrition and medical value, at present, astaxanthin is applied to culture fishery mainly as new and effective feed addictive in the world, has been applied in the breeding process of salmon, salmon, trout, prawn and pet fish etc.Owing to the most of nutriments absorbed can be used for gonad development after the salmon trout entering maturity period, therefore fish-egg can do one's utmost to absorb astaxanthin, make fish-egg nutritious substances accumulation more horn of plenty present bright-coloured Chinese red, thus make the caviar of production have higher nutritive value.

Because free pantothenic acid is unstable, hygroscopicity is strong, so in actual production process, its calcium salt conventional such as D-VB5 calcium replaces pantothenic acid.The deficiency of pantothenic acid, can make many Organ and tissues of body impaired, shows skin and mucous membrane generation pathology, inflammation; Enteron aisle and respiratory tract susceptible disease, Reproductive Performance is disorderly, and poor growth loses weight, nerve problems, and antibody is formed and is suppressed.Fish bulk-growth can be caused slow so lack pantothenic acid, Reproductive Performance generation obstacle, adaptability reduces.

N-3HUFA is that parent population grows required highly unsaturated fatty acid, lacks the reproductive performance that significantly can affect parent population, comprises ovum quality and quantity etc.

Normal reproductive function also needs to maintain with taurine.Have data to confirm, in cat feed content of taurine lower than 0.101% time, its reproductive function is bad, and stillborn foetus, miscarriage and birth defect rate increase, pup survival rate decline.Containing more than 0.105% time, normal reproductive function could be maintained.

[beneficial effect]

The present invention compared with prior art, has following beneficial effect:

Feed of the present invention meets the requirement of silverside parent population to nutrition, and it can induce silverside to take food, and improves the immunity of parent population, promotes silverside gonad development, improves parent population and to grow required energy.
