Abstract

The invention discloses loach fry feed which is composed of, by mass, 20%-30% of imported fish meal, 15%-20% of conch and clam meat powder, 5%-10% of earthworm powder, 5%-10% of flour weevil powder, 5%-8% of spiral seaweed powder, 5%-8% of yeast powder, 12%-17% of pork liver powder, and 12%-15% of corn gluten meal. The raw materials are pulverized by an ultrafine grinder, screened by a 100-mesh bolting-silk net, put into a feed stirrer according to a ratio and stirred for 40 minutes, evenly mixed, and stored after being air-dried. Multiple animal raw material powders, spiral seaweeds, yeast and the corn gluten meal and the like are adopted, and the prepared feed is unique in smell, high in feeding attraction, high in nutritive value, easy to digest and suitable for being fed to loach fry and provides high-quality animal protein for the loach fry.

Description

A kind of loach fry feed

Technical field

The present invention relates to field of fodder, be specifically related to a kind of loach fry feed.

Background technology

Loach is known as " in water ginseng " is a kind of delicious flavour, nutritious aquatic fish, along with the increase of loach market demand, loach propagates just progressively large-scale development artificially, loach large-scale farming is in great demand to loach fry, loach fry stage supply of forage seems particularly important, loach is more voracious in the one-tenth loach stage, better to feed ration size, be then main feed with zooplankter in the fry stage, supply of forage deficiency usually causes loach fry batch dead, loach artificial breeding survival rate is significantly declined, some loach fry cultivating survival rates are less than 20%.

Summary of the invention

For overcoming above-mentioned defect, the present invention devises a kind of loach fry feed.

Technical scheme of the present invention is, a kind of loach fry feed, its component is: imported fish meal 20%-30%, spiral shell freshwater mussel digested tankage 15%-20%, earthworm powder 5%-10%, yellow meal worm powder 5%-10%, spirulina powder 5%-8%, dusty yeast 5%-8%, pork liver powder 12%-17%, corn protein powder 12%-15%, percentage is mass percent.

Above-mentioned raw materials is pulverized through micronizer, sieves with 100 mesh sieve tulles, puts into fodder mixing machine stir 40 minutes according to proportioning, puddles evenly, air-dry rear storage.

Beneficial effect: formula of the present invention selects many animals raw meal, spirulina, yeast and corn protein powder etc., the feed smell of preparation is unique, and attractant is strong, be of high nutritive value, and be easy to digestion, be applicable to ingesting, for loach fry provides high-quality animal protein of loach fry.

Detailed description of the invention

Embodiment 1: imported fish meal 30%, spiral shell freshwater mussel digested tankage 15%, earthworm powder 10%, yellow meal worm powder 5%, spirulina powder 8%, dusty yeast 8%, pork liver powder 12%, corn protein powder 12%, percentage is mass percent; Above-mentioned raw materials is pulverized through micronizer, sieves with 100 mesh sieve tulles, puts into fodder mixing machine stir 40 minutes according to proportioning, puddles evenly, air-dry rear storage.

Application example: Nansi Lake loach breeding field, be 1.5 mu of ponds at an area, put loach fry 300,000 tail in a suitable place to breed, throw in the feed according to embodiment 1 formulated, arrange a same pond in addition and carry out contrast cultivation, the contrast pond traditionally fry mode of throwing something and feeding is cultivated; Test carries out 22 days altogether, first 10 day every day is thrown something and fed 10 jin in test tank cultivation, from the 11st day, every day increases by 1-2 jin, catch loach fry 10.1 ten thousand tail that specification is 3-5 centimetres, survival rate of fish fry 33.7% to receiving when the 22nd day, contrast pond loach fry goes out the pool 5.8 ten thousand tail, survival rate is only 19.5%, and test tank improves 14.2% than contrast pondfish shoot survival percent.

Embodiment 2: imported fish meal 25%, spiral shell freshwater mussel digested tankage 20%, earthworm powder 5%, yellow meal worm powder 7%, spirulina powder 8%, dusty yeast 5%, pork liver powder 15%, corn protein powder 15%, each percentage is mass percent; Above-mentioned raw materials is pulverized through micronizer, sieves with 100 mesh sieve tulles, puts into fodder mixing machine stir 40 minutes according to proportioning, puddles evenly, air-dry rear storage.

Application example: Weishan Lake summer town loach breeding field, be 2 mu of ponds at an area, put loach fry 380,000 tail in a suitable place to breed, throw in the feed of embodiment 2 formulated, arrange a same pond in addition and carry out contrast cultivation, the contrast pond traditionally fry mode of throwing something and feeding is cultivated; Test carries out 25 days altogether, first 7 day every day is thrown something and fed 12 jin in test tank cultivation, 8-15 day, throw something and feed 16 jin every day, after the 16th day, every day, feeding volume increased by 1.5 jin, catch loach fry 12.4 ten thousand tail that specification is 3-5 centimetres, survival rate of fish fry 32.6% to receiving when the 25th day, contrast pond loach fry goes out the pool 7.3 ten thousand tail, survival rate is only 19.2%, and test tank improves 13.4% than contrast pondfish shoot survival percent.

Embodiment 3: imported fish meal 20%, spiral shell freshwater mussel digested tankage 17%, earthworm powder 7%, yellow meal worm powder 10%, spirulina powder 6%, dusty yeast 8%, pork liver powder 17%, corn protein powder 15%, percentage is mass percent; Above-mentioned raw materials is pulverized through micronizer, sieves with 100 mesh sieve tulles, puts into fodder mixing machine stir 40 minutes according to proportioning, puddles evenly, air-dry rear storage.

Application example: Fu Cun mono-loach breeding family, be 1.7 mu of ponds at an area, put loach fry 280,000 tail in a suitable place to breed, throw in the feed of embodiment 3 formulated, arrange a same pond in addition and carry out contrast cultivation, the contrast pond traditionally fry mode of throwing something and feeding is cultivated; Test carries out 20 days altogether, first 7 day every day is thrown something and fed 10 jin in test tank cultivation, from the 8th day, every day increases by 1-2 jin, catch loach fry 11.2 ten thousand tail that specification is 3-5 centimetres, survival rate of fish fry 40% to receiving when the 20th day, contrast pond loach fry goes out the pool 6.3 ten thousand tail, survival rate is 22.5%, and test tank improves 17.5% than contrast pondfish shoot survival percent.
