Background technology
Fly maggot nutrient component is comprehensive, high protein, low sugar and low fat, and contain abundant mineral matter element, vitamin, trace element and antibacterial substance, without antinutritional factor and noxious material, be a kind of and abundant and valuable resource.The crude protein content of fly maggot is 62.52 %, essential amino acids content accounts for 47.72 % of total amino acid, the ratio of essential amino acid and dispensable amino acid total amount is 0.91, according to the good protein forage standard of United Nations Food and Agricultural Organization and World Health Organization's proposition, its essential amino acid accounts for 40 % of total amino acid content, and TEAA should surpass with the ratio of dispensable amino acid total amount
0.6, and fly maggot essential amino acid is 2.3 times of fish meal, and methionine content is 2.7 times of fish meal.In view of this nutrient component of fly maggot can meet the standard of high-quality protein, aspect albumen quality, is better than fish meal.
The crude fat content of fresh maggot is lower, be only 5.4 %, compare with meat, only higher than chicken and carp, but the unsaturated fatty acid content of fly maggot powder is abundant, up to 68.2 %, essential fatty acid is also up to 36 %, and the total sugar content of fresh maggot is only 0.9 %, except being starkly lower than soybean, suitable with the sugared content of other foods, belong to low sugar resource.Fly maggot powder also contains plurality of inorganic salt and vitamin, and rich content, vitamin A, vitamin D and vitamin E content are respectively 727.8 and 131 μ g/100 g and 10.04 mg/100 g, and Fe, Zn and Se content are respectively 268,159 and 8.9 mg/kg.As can be seen here, fly maggot is the animal protein feed of high-quality, and fly-maggot feed good palatability, and conversion ratio is high, nutritious; With fly maggot powder, make feed and can improve animal product quality, reduce feeding cost, greatly improve culture benefit, alleviated again the pressure of present feed shortage simultaneously.
But the technology content that cultivates at present fly maggot is lower, be mainly extensive cultivation, this cultivation advantage is easy grasp, input cost is low, workable, is the mode that current most fly maggot breeding person adopts.In practice, fly maggot breeding, mostly as the supplementing of the aquacultures of certain livestock and poultry, by utilizing feces of livestock and poultry to produce fly maggot, adds in feed and reduces feeding cost, seldom has and only relies on single fly maggot breeding to develop into industry.
In the scale of fly maggot, controlledization cultural technique technique; fly blow efficiently lure collection with quantification be important step; being that monitoring fly lays eggs, indispensable technical matters in cultivation situation, is also fly large-scale cultivation and fly blow quantification, dispensing and fly maggot standardization, controlledization cultivation and the technical matters link of indispensability while inoculating.Chinese patent CN101156564 discloses a kind of method for enticing collection of housefly oosphere, its method is: the attractant that the agricultural byproducts that the cloth of use thickness 0.5~3mm or paper parcel were fermented by microorganism or feces of livestock and poultry form, and show to form at cloth or paper the gauffer that the degree of depth is 0.5~2cm, housefly is laid eggs in gauffer, with scraper, gently fly blow is scraped, obtain fly blow.Chinese patent CN 102524195 A disclose a kind of efficient trap method for flyblows of flies, sprinkle foodstuff and lure ovum reinforcing agent to reach fly blow, efficiently to lure the order of collection connecing on ovum dish.
The present invention, by the making bed of laying eggs, by ovum collecting, not only can strengthen and lure collection effect, and fly can high concentration be laid eggs, and it is separated that fly blow and collection ovum material are easy to, and adjustable point, regularly, collect continuously, easy to operate.
Summary of the invention
The object of the present invention is to provide a kind of fly blow collection method, not only can strengthen and lure collection effect, fly can high concentration be laid eggs, it is separated that fly blow and collection ovum material are easy to, and adjustable point, regularly, collect continuously, easy to operate.
To achieve these goals, the technical solution adopted in the present invention is:
A fly blow collection method, comprises the steps:
(1) select sizeable white plastic basin, prepare decoy in basin simultaneously, decoy is put into basin;
(2) make sizeable sponge block, with black cotton, sponge block is all wrapped, tightened, put in the shelf made from stainless wire mesh, keep sponge outstanding, can take easily and stack, carried out the standard bed of laying eggs;
(3) bed of laying eggs is put in the plastic basin that installs decoy, allowed a sponge that lays eggs fully absorb the moisture content of decoy, the bed of laying eggs is noted supplementing the decoy in basin after sponge sucks in water, makes the water surface of decoy in basin all the time at 5cm ~ 10cm;
(4) basin and the bed of laying eggs are put in fly room for kind of a fly and laid eggs in the above;
(5) according to early, evening each once, from stainless (steel) wire guide frame, take out the sponge bed of laying eggs, water is flushed to ovum in fixing dress ovum container, completes the collection of ovum, after having rinsed, cotton sponge block is put on stainless wire mesh shelf again, continues to collect fly blow;
The described plastic basin of step (1) is of a size of 40cm*60cm*12cm; The compound method of the interior decoy of basin that step (1) is described is: according to volume ratio, be 1:10000 ratio preparation ammonia spirit, put into plastic basin, and water surface elevation be 6 ~ 8cm; The described shelf of step (2) is of a size of 30cm*70cm*5cm; Sponge block is of a size of 28cm*68cm*6cm; The gradient that the bed of laying eggs that step (3) is described is placed in basin is 15 ~ 20 degree.
The invention has the beneficial effects as follows:
(1) by the making bed of laying eggs, adjustable point, regularly reach the effect that efficiently lures collection fly blow, easy to operate, keep clean environment degree between breeding room, and can collect continuously, reduce costs.
(2) the black cotton of selecting is all wrapped sponge, is tightened, and as luring logging material, draw materials conveniently, and direct water is flushed to ovum in fixing dress ovum container while receiving ovum, convenient and swift.
(3) in basin, lure ovum thing to select dilute ammonia solution, safety non-toxic, with low cost, can Industry Promotion.
