Description
Technical field
The present invention relates to a kind of feed for river crab, particularly a kind of dried silkworm chrysalis feed for river crab and preparation method thereof and scale of feeding.
Background technology
River crab is because natural one-tenth crab wretched insufficiency.At present, in the aquatic farm large tracts of land, propagate artificially on a large scale.Cultivation density is big when propagating into crab artificially on a large scale by what, brings the ecological environment of supporting crab poor, and water plant and aquatic animal wretched insufficiency that river crab is edible are supported crab and needed to replenish bait relatively largely.The quality of bait directly influences the speed of growth, quality, grade, the economic benefit of crab farming and whole ecological benefits, economic benefit and the social benefit of foster crab industry of river crab.
Summary of the invention
The purpose of this invention is to provide a kind of dried silkworm chrysalis feed for river crab and preparation method thereof and scale of feeding.Use this feed can raise out fast growth, high-quality red testis river crabs that quality is good, of high grade.The economic benefit of crab farming can be greatly improved, the sustainable development and foster crab whole ecological benefits, economic benefit and the social benefit already of supporting the crab industry can be greatly improved.
Technical scheme of the present invention is: a kind of dried silkworm chrysalis feed for river crab, this feed is based on dried silkworm chrysalis, with dried fish, dusty yeast, shrimp shell meal, soybean lecithin, big dregs of beans, peanut meal, corn protein powder, wheat bran, vegetable oil, calcium dihydrogen phosphate, calcium lactate, premix through pulverize, dry, mixed, slaking, granulation and make, be characterized in:
The raw material of dried silkworm chrysalis feed for river crab and parts by weight thereof are:
Dried silkworm chrysalis 25-27 part dried fish 8-10 part dusty yeast 3-5 part
The big dregs of beans 12-16 of shrimp shell meal 9-11 part soybean lecithin 4-6 part part
Peanut meal 7-9 part corn protein powder 5-7 part wheat bran 9-13 part
Vegetable oil 0.7-1.1 part calcium dihydrogen phosphate 2-2.4 part calcium lactate 0.3-0.5 part
Premix 3-5 part.
The preparation method of described dried silkworm chrysalis feed for river crab comprises the steps:
1., raw material is prepared: raw material and parts by weight thereof by above-mentioned a kind of dried silkworm chrysalis feed for river crab are prepared various raw materials.
2., the pulverizing of raw material, drying: with above-mentioned 1. in each particulate material pulverize and dry.
3., raw material is mixed: with 1. above-mentioned and 2. in each raw material carry out fully mixed.
4., the slaking of raw material: above-mentioned blended stock is 3. made its slaking with the atmospheric steam steaming.
5., the granulation of raw material: with above-mentioned slaking material 4. be pressed into particle the dried silkworm chrysalis feed for river crab of the present invention.
The scale of feeding of described dried silkworm chrysalis feed for river crab is according to the different water temperatures of various seasons and the river crab body weight above-mentioned prescription feed of throwing something and feeding in good time, in right amount:
The ratio (%) that the scale of feeding of concrete feed accounts for the river crab body weight sees the following form:
| Coolant-temperature gage | Below crab body weight 50 grams | Crab body weight 50-75 gram | Crab body weight 75-100 gram | Crab body weight 100-125 gram | Crab body weight 125-15 0 gram | Crab body weight 150-17 5 grams |
| ??12℃-16℃ | ??3.0％ | ??2.8％ | ??2.8％ | ??2.8％ | ??2.8％ | ??2.5％ |
| ??17℃-21℃ | ??3.5％ | ??3.8％ | ??3.8％ | ??3.8％ | ??3.8％ | ??3.5％ |

| ??26℃-30℃ | ??3.8％ | ??4.0％ | ??3.5％ | ??3.5％ | ??3.5％ | ??3.0％ |
Feed of the present invention utilization nutrient balance technology, the appliable plant albumen raw material and an amount of vitamin that are converted into animal protein makes feed reach nutrient balance emphatically.According to the different water temperatures and the river crab body weight of river crab various seasons, the feed of throwing something and feeding in good time, in right amount reaches and improves river crab nutrient absorption rate, strengthens the river crab immunologic function, improves river crab growth rate and coefficient of condition.
In culturing the pool, river crab is a main bait with pasture and water, shellfish, shrimps etc.But when above-mentioned bait can not satisfy breed red testis river crabs needs, when particularly later stage crab growing and fattening, appetite increase, throw something and feed in good time, in right amount by above-mentioned with dried silkworm chrysalis serve as main that make, to contain the high cured feed of the protein content river crab of feeding be the crux of realizing the technical program.
In the above-mentioned feed, its maximum characteristics are to have used the dried silkworm chrysalis of raw material that is converted into animal protein by vegetable protein in a large number, and dried silkworm chrysalis accounts for 1/4th in whole forage compounding.The composition of dried silkworm chrysalis is: moisture 7.30%, crude protein 56.90%, fat 24.90%, crude fibre 3.30%, NFE 4.00%, coarse ash 3.60%.In dried silkworm chrysalis, crude protein accounts for 56.90%.Add in big dregs of beans, soybean lecithin, peanut meal, corn protein powder and wheat bran and all have a large amount of vegetable proteins.Its concrete protein content is: crude protein accounts for 43.0% in the big dregs of beans, and crude protein accounts for 9.4% in the corn, and crude protein accounts for 47.8% in the peanut meal, and crude protein accounts for 44.3% in the corn protein powder, and crude protein accounts for 15.7% in the wheat bran.In the feed formula of the present invention like this: the amount that vegetable protein is converted into animal protein is 14.22%; The animal protein amount is 7.46%; The vegetable protein amount is 17.05%, and the albumen total content reaches 38.73% in this feed formula.Wherein vegetable protein is converted into the amount of animal protein and the amount of vegetable protein just reaches 31.27%, accounts for 80% of forage protein total content.Such high protein feed guarantees to raise out fast growth, high-quality red testis river crabs that quality is good, of high grade.
The invention has the beneficial effects as follows provides a kind of dried silkworm chrysalis feed for river crab and preparation method thereof and scale of feeding.Use this feed to raise out fast growth, high-quality red testis river crabs that quality is good, of high grade.Greatly improve the economic benefit of crab farming, greatly improved the sustainable development of foster crab industry and whole ecological benefits, economic benefit and the social benefit of foster crab industry.
