Detailed description of the invention

Food grass pig feed in the present invention is using maize straw as roughage major ingredient, and the maize straw of utilization has green period results, smooth skin, fully dry, and maize straw also contains the carbohydrate of more than 30%, can Direct-fed.With regard to herbivore, the maize straw net energy for gain of 2kg is equivalent to the corn kernel of 1kg, analyzes according to the study, and digestible energy contained in maize straw is 2235.8kJ/kg, and nutritious.Maize straw is dried rear pulverizing, is made into high nutrition, the feed of suitable livestock taste.

Oil chaff is product after paddy processing, is not outer field chaff, neither the rice of nexine, be exactly the mid portion of paddy, the endothelium that one deck is very thin, has good nutritive value, carbohydrate, grease and protein are main, also containing more ash content and vitamin, phytic acid calcium etc.

Soybean stalk is after selecting beanpod, the general name of cauline leaf (fringe) part.The product of Photosynthesis in Soybean effect has and is over halfly present in stalk, and soybean stalk is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter etc., is that one has multiduty reproducible living resources.After soybean plucks pod, stalk delays to gather in the crops, and natural air drying, pulverizes together with maize straw, and our thick fine feature of soybean stalk is crude fiber content high (9%-30%), and containing lignin etc.Though lignin can not utilize by general family pig, can well be absorbed by food grass pig and utilize.Soybean stalk can also reduce the stink of ight soil, reduces atmosphere pollution.

Phytophage pig feed contains crude fibre in joining.Crude fibre, for BaMa miniature pig, by the fermentation of caecum and large intestine microorganism, utilizes crude fibre strengthen healthy and maintain GI microecological balance.Piglet can utilize the fiber of a great deal of, and after fiber arrives hindgut, can to the microecological balance promoting enteron aisle by fermentable, strengthen intestinal health, reduce diarrhea rate, in control grice diarrhoea, there is special effect, and crude fibre can stimulate the secretion of gastric juice, bile, pancreatic juice.The harmful substance produced in the adsorbable alimentary canal of feed fibre, makes it excrete, and appropriate feed fibre in rear intestinal fermentation, can reduce the PH of rear intestinal contents, suppresses the growth of the pathogens such as Escherichia coli, prevents the generation of grice diarrhoea.In the fattening later stage, increase fiber in feed, can fat deposition be reduced, improve carcass lean meat percentage, and the fiber containing some, certain quality in slightly raising, be conducive to the growth performance improving piglet.

Crude fibre can also improve immunity.Normal microbial flora especially GI flora energy stimulation of host sets up complete immune system.Along with each stage of pig growth and development is different, the normal microflora definite value of variety classes and quantity is in gastrointestinal tract mucosa and gastrointestinal content, form GI dynamic microbial balance, this balance effectively organizes invasion and the breeding of the external microorganism such as malignant bacteria and virus.In pig intestines and stomach, anaerobic bacteria has comparative advantage (accounting for more than 90%), and these bacterium produce volatile fatty acid and lactic acid in metabolic process, reduces the pH value in living environment, thus suppresses the growth and breeding of foreign bacteria.Meanwhile, anaerobic bacteria is combined with gastrointestinal tract mucosa endothelial cell tight, and form the biomembrane of one deck Membranous flora, this tunic serves protective effect to host.Microflora can not only stimulate the growth of Immune Organs of Body, and is indispensable to enhancing body specific cell and humoral immunity.

Containing the abundant nutritional labeling such as calcium, squama, potassium, cellulose in feed, facilitate utilization and the absorption of nutriment, improve meat quality comprehensively, produce fresh and tender pure natural green food.

Below the processing of feed in the present invention and using method are described.

1, maize straw is gathered in the crops at green period; After soybean plucks pod, stalk delays to gather in the crops, and dry in its natural state, moisture is less than 8%, puts into the place that is not caught in the rain, kept dry.

2, use 9FQ-400 type hammer type feedstuff crasher, stalk is put into pulverizing chamber equably by charging aperture, the hammer leaf of High Rotation Speed is had in pulverizing chamber, upper machine body is built with stationary knife moving knife and tooth plate, the stalk added is ground into rapidly powdery under the pound of hammer leaf and tearing between hammer leaf and tooth plate act on rubbing etc., due to the effect of centrifugal force and pulverizer cavity of resorption negative pressure, material in small, broken bits falls cavity of resorption by sieve aperture, sucked by blower fan afterwards, again by blower fan deliver to gather materials between in control of dust, manually collect dress more afterwards, 9FQ-400 type hammer type feedstuff crasher adaptability is good, energy crushing maize, Chinese sorghum, stalk, peanut seedling, herbage, etc. multiple kind of raw material.This machine adopts full steel structure, is the regeneration product of old-fashioned pulverizer.Operation principle: this machine is tangential admission beater disintegrating machine.In pulverizing chamber, rotor high-speed rotates, and feed is ground into particulate by the strike of hammer leaf and the rubbing action of tooth plate, leaks down from sieve aperture, then has centrifugal fan to inhale and delivers to storing bag or the room that gathers materials.Processing fineness can regulate by changing screen cloth as required.

3, add oily chaff, with cornstalk powder proportion for 50%, soybean stalk powder proportion is 30%, and oily chaff proportion is 20%.Manually mix thoroughly, form grass pig feed.

In this feed, the nutritional labeling containing following mass ratio: crude protein 8.40%, crude fat 6.28%, crude fibre 9.66%, calcium 0.311% and phosphorus 0.24%.Wherein maize straw contains: crude protein 5.52%, crude fat 2.41%, crude fibre 11.98%, calcium 0.11%, phosphorus 0.17%.Oil chaff contains: crude protein 11.89%, crude fat 11.18% crude fibre 4.12%, calcium 0.32%, phosphorus 0.37%.Soybean stalk contains: crude protein 10.91%, crude fat 9.46%, crude fibre 9.49%, calcium 0.64% and phosphorus 0.27%.

4, every morning 6:00, afternoon 19:00, feed BaMa miniature pig grass pig feed, with at every turn feed before, feed shows a small surplus, or eats up as fed standard amount.

5, rearing contrast test shows: maize straw, soybean stalk and oily chaff are mixed according to the ratio of 5:3:2, fully mix feeding BaMa miniature pig, one day two meal, BaMa miniature pig health, meat, labor utilization reach most favo(u)red state.

The present invention takes full advantage of agricultural crop straw, turns waste into wealth, and stalk is used as the feed of phytophage pig and uses, not only reducing environmental pollution, and greatly reduce the cost of feed, increases the profit of pig farmer.

Compare with the pig kind of foreign country the characteristic that Chinese native pigs natively has crude feed tolerance, Chinese native pigs is fed roughage, not only can stimulate pig intestines and stomach, promote that gastrointestinal development is perfect, strengthen digestion power, and the lean meat percentage of trunk can also be improved.Feed based on the roughage of the stalk of soybean and corn, directive breeding is carried out to pig, strengthens its resistance to thick characteristic, and their offspring is consolidated and developed in resistance to thick feature.And show through experimental study, the fragrant pig that this feed formula is fed is healthy, and pork mouthfeel is good, is worth high.

BaMa miniature pig, from 2009, experiences 10 epoch, under grass pig feed forage feed, grows up healthy, and the BaMa miniature pig of feeding out, compared with the pig of the control group of corn-soybean meal forage feed, has many fine qualities such as the few and heat of fat content is low.The nutritional labeling such as muscle fat, flavor substance of feeding contained by pork with regard to this feed formula is totally better than common domestic pig.
