Embodiment 2:
The full expanded pellet feed of the present invention draws following data through the experiment of feeding in 2 years:
(1) economize on resources:
The utilization rate of traditional its feed of mink farming is low, and feed is converted into that the feedstuff-meat ratio of mink is 5-6:1 behind the dry, and its feedstuff-meat ratio of the full expanded pellet feed of novel mink is 3-3.2:1.Calculate by a pair of mink (female ermine of a public ermine) older 6 jin of meat:
The a pair of mink of conventional feed will be used feed: 6*6=36 jin,
The a pair of mink of pellet will be used feed: 6*3.2=19.2 jin,
The comparable conventional feed saving of pellet: 36-19.2=16.8 jin, 4,000 ten thousand of the breed total amounts of national mink, 16.8 jin of material of a pair of saving can be saved 16.8 ten thousand tons feed altogether.This means that this year has 16.8 ten thousand tons fish, meat, grain to be saved.
(2) environmental protection:
After having improved the digestibility and utilization of mink to feed, the ight soil quantity that animal is discharged to the external world will reduce, and the digestibility of conventional feed has only about 65%, 36*0.35=12.6 jin ight soil; The digestibility of pellet can reach 85%, 19.2*0.15=2.88 jin ight soil; Each is to reducing by 9.72 jin ight soil, and 9.72 ten thousand tons ight soil can be discharged in 1 year less in 4,000 ten thousand in the whole nation to the external world.
(3) improve the growth performance of mink, improve its fur price:
Traditional mink farming is owing to feed nutrition, and the public ermine of the body weight when the hormone ermine is got skin is about 3.5-5 jin, and the price of hide is about 300 yuan; About female ermine 2.2-2.5 jin, the price of hide is about 170 yuan.
Mink public ermine body weight when getting skin that the application mink is fed with full expanded pellet feed can reach 5.5-6.5 jin; Female ermine 2.8-3.3 jin.The quality of this body weight and the hide of getting can compare favourably with one-level fur in the world.The public fur price of the international auction meeting upper level in this year can reach about 500 yuan, and female fur can reach about 240 yuan.One public one female mink is worth and can improves 300 yuan on year-on-year basis.The whole nation 4,000 ten thousand increases income 30,0*2,000 ten thousand=6,000,000,000 yuan only.
(4) reduce human cost:
Each poultry raiser of tradition mink farming can raise young beastly that the female ermine of 180 kinds to the female ermine of kind in growth period produces.Surviving 4 young ermines by the female ermine of every kind of female ermine calculates.Can raise 900 at most.
Using the full expanded pellet feed of mink, singlely can raise 3000-5000 mink at most, can reduce poultry raiser's number 8-9 people by the ermine field of 10000 breed amounts, is 24000 yuan of calculating with for each person every year wage level, can save 19.2 ten thousand yuan.
(5) mink with its feedstuff-meat ratio of full expanded pellet feed well below traditional aquatic foods material:
The feedstuff-meat ratio of its bright material of traditional mink farming is 15-16:1, and the unit price of its bright material is at 1.4-1.5 unit/jin, and the one jin of ermine that grows needs 21-24 unit; Using its feedstuff-meat ratio of full expanded pellet feed is 3-3.2:1, and its unit price is 5.5 yuan/jin, and the one jin of ermine that grows needs 16.5-17.6 unit.The one jin of comparable tradition of ermine of growing is cultured and is saved 4.5-7.5 unit.Calculate female ermine of breed by the long 2 jin of meat of female ermine and can save 15 yuan, the long 3.5 jin of meat calculation of public ermine is cultured a public ermine and can be saved 26.25 yuan.
