Description

Animal protein feed and preparation method thereof

The invention belongs to the preparation method of a kind of protein feeds and this feed.

Along with developing rapidly of aquaculture and feed industry, the wretched insufficiency of animal protein feed has been the problem that presses for solution.The employed animal protein feed of China's feed industry mainly is a fish meal at present, just adds a certain amount of fish meal in feed, to improve the biological value of feed protein.The fish meal overwhelming majority that is added in China's feed needs import, and it not only will spend a large amount of foreign exchanges, and the cost of feed also can be increased widely.In order to seek other approach of animal protein in the feed, someone produces the animal protein that feed is used by the method for artificial feeding maggot fly, this method weak point is: it is to utilize corrupt substance to produce the maggot fly, its production environment is poor first, second causes second environmental pollution easily.

The objective of the invention is to utilize materials such as stable dung and crop stalk to be raw material, with white star brevitarsis larva is carrier, produce a kind of animal protein feed, substitute fish meal, and have characteristics such as value of environmental protection height, small investment, easy operation with high nutritive value.

The present invention realizes like this, it is by culturing white star brevitarsis larva in batches, with its oven dry, pulverize and to make the animal protein nutrient fodder or, in the temperature environment below 5 ℃, refrigerate white star brevitarsis larva, make pellet together with main feed then.

The said white star brevitarsis of the present invention has another name called the white star chafer, white star is spent latent, lineae ablicantes copper brevitarsis.Belong to coleoptera, brevitarsis first section.Its morphological feature is: the long 18-24mm of adult, and wide 9-12mm, to compare build medium with the chafer of other kinds, ovalize, the back side is flat, and the black copper look littlely is with green or purple flash of light, scatters a plurality of irregular white suede spots, the feeler aterrimus, lamelliform 11 joints, excellent portion male worm is long, and female worm is short.Pronotary is slightly like bell, surplus gather little punctum and the irregular white hair spot 10.Elytrum is roomy closely square, and has surplus the irregular white hair spot 10, and all there is a white mao spot each uromere both sides of the outside of belly.Podical plate is exposed to outside the elytrum, and a pair of white hair spot is arranged on it.The ovum ovalize is about long 1.7mm; Milky is smooth.The long 40-50mm of ripe larva body, more than the body weight 5g, bodily form hypertrophy, the less brown that is of head, chest white, bending is " C " font.Abdomen does not save and expands, and 2 stringer setas are arranged on the anus sternite, every capable 19-22 root, and arrangement is the font of falling u, and belly is up during walking.About the long 22mm of pupa, oval, the blunt circle of head end, gradually thin backward, first milky, gradual change yellowish-brown, crineous before sprouting wings.The history of life of white star brevitarsis and habit: a generation took place in 1 year in the white star cockchafer, survived the winter in soil with larva, pupated between next year four, May.A large amount of emergence adults between seven Augusts under North China's natural conditions, how movable before and after at noon adult, get food, likes getting food having on the fruits such as the pears of wound, apple, peach, and often have several to eat to 10 remainder groups.Adult has phototaxis and seemingly-dead habit, during low temperature if run into judder land seemingly-dead, during high temperature or be subjected to slight vibration then to fly immediately to escape.Very strong to wine vinegar liquid taxis.Happiness is laid eggs in the many soil of humus or dunghill etc. is located single female average out to 18-25 grain of laying eggs, 7-11 days ovum phase after the adult mating.Larva is a foodstuff with humus, muck.The aging back of larva in spring in next year is done oval native chamber and is pupated in dark soil layer.

The preparation method of this animal protein feed is: first artificial feeding, and both can raise and train wild larva and begin, also can be from raising and train wild adult.Because wild adult is convenient to collect, generally begin starting from the breeding of wild adult.If begin then to arrest in a large number by orchards such as peach, apples in the annual 7-8 month from raising and train wild adult, select then, to select abdominal distention obvious for female insect, the female worm of the big and white suede spot of bodily form distinctness; For male insect, select excellent portion to grow better, it is significantly individual that stature reaches white suede spot greatly.If begin to raise and train from larva, then after annual December, under the higher weeds heap of stable dung or other humus contents, catch, select active strong, stature is big, varietal characteristic is outstanding larva then.Enter after the normal raising, select defect individual from adult raising or larva, raising circulates.

To the raising of white star brevitarsis adult, it is higher that its place should be selected in physical features, the leeward area without shade of being convenient to ventilate.Protecting wire net is set and carries out ground and suitably handle, in case the harm of other animals and prevent the adult escape.The feed of its raising gets final product with the fruit of permanent disability, as apple, peach etc.Collection for the ease of worm's ovum, raising district adult is provided with the ovum bed, constituting of its ovum bed is following with a pallet, on this pallet, divided one deck nutrition base, its nutrition base is animal wastes with after pulverized plant straw or edible fungus bran or fermentation industry leftover bits and pieces mix mutually, and the material that forms through fermentation.Selected animal wastes chicken manure preferably also can be pig manure or other herbivorous animal ight soil in its nutrition base.The thickness that spreads the nutrition base on pallet for well, according to amount number and the time that adult is laid eggs, is changed the ovum bed with 3-8cm in time on the ovum bed, basic identical to guarantee that worm's ovum is hatched the time, results when being beneficial to instar larvae.

Raising for larva: at first will disposable nutritional bed be set to larva, its disposable nutritional bed is on the ground of being crossed by cure process, the thick nutrition base of 25-40cm is set one time, and its nutrition base is plant straw or edible fungus bran or the material of fermentation industry leftover bits and pieces after fermentation after animal wastes and quilt are pulverized.Chicken manure is preferably selected in its animal wastes, also can be pig manure or other herbivorous animal ight soil.When making the nutrition base, its animal wastes account for the 40-70% of nutrition base gross weight.All the other are the plant straw.Then larva is seeded in the nutrition base equably, stocking density is advisable with every square metre of 700-1000 head.On the nutrition base, cover the thick plant straw of one deck 10-25cm, on the plant straw, cover a plastic foil at last.Between feeding period, the relative humidity of its nutrition base should remain on 50-65% and be advisable.

The results of ripe larva: gather in the crops after having larva 80% or more well-done, the standard of its larva maturation is that whole polypide fills, pure white smooth, afterbody loses presence of residual feces.At this moment stop the nutrition base and preserve moisture, and add forced ventilation, larva is shifted to lower floor, degrade the top of nutritional bed so earlier,, raise labour efficiency, larva is separated from the nutrition base to reduce separating difficulty.

The utilization of ripe larva: this larva as feed by way of mainly containing two, the one, direct oven dry is ground into powder then, joins in the main feed according to certain ratio; The 2nd, utilize the hibernation of larva, with the larva after the maturation results, in being environment below 5 ℃, temperature refrigerates, the larva that will be refrigerated is processed into pellet with main feed, can prevent hyperthermia drying like this and cause a large amount of losses of life active compound, with the biological value of raising product, and can utilize all the year round.

In the time of need turning into adult to the improved seeds of choosing larva, should between nutrition base and ground, lay the soil layer of a bed thickness 10-20mm, pupate so that the ripe laggard underground layer of larva is done oval native chamber, with the adult that needing to obtain.

Because the production method of this animal protein is to be raw material with the stable dung and the straw that produce in the farming and animal husbandry production process, not only the source of raw material is wide, and price is low, also has the higher value of environmental protection, and its investment is also fewer, and operation easily; It is medium that this animal protein is selected the larva of white star brevitarsis for use, likes the polypide that eats because this larva is poultry, domestic animals such as chicken, duck, the biological value height of its product, and utilization rate can reach more than 90%.This product is the ideal substitute of fish meal, is better than fish meal at aspects such as the immunity that improves body, enhancing resistances against diseases again.The production of this animal protein has advanced and has produced by resource-hungry striding forward to the ecological circulation type.
