Background technology
Along with the raising of people's living standard, market proposes to produce more efficient, the safer requirement of product to aquaculture.But the expansion of cultivation scale causes feed grain consumption to surge, and has threatened the overall situation of grain security, and has badly influenced the lifting of culture benefit.Ox, support, the plant-eating animal such as rabbit, goose can efficiently utilize the physiological property of vegetable protein because of it, and is more and more subject to the attention of animal husbandry.The effective way that solves feed grain deficiency by making full use of herbage and crop material.In production, pay much attention to kind of a grass, but processing and the improvement of herbage are ignored, adopt the mode of Direct-fed, nutrition fiting effect is poor, livestock and poultry digest and assimilate not, feed conversion rate is low, a large amount of nutritional labelings are excreted external, both increase the weight of aquaculture cost, improved again the burden of environmental pollution improvement.
Pellet can, according to the nutritional need of the each growth and development stage of different plant-eating animals, be determined raw material smashing fineness and formula, improves utilization of nutrients.In pellet preparation process, be subject to the effect of temperature, moisture and extruding can significantly improve feed palatability, also there is lot of advantages simultaneously, as: kill entomogenous fungi, extend storage time; Reduce feed volume, reduce cost of transportation and storage space etc.Ramie be a kind of biological yield high, be rich in protein, lysine and calcareous herbaceos perennial.China utilizes ramie to do the with a long history of feed, but generally take search for food fresh leaf or cured leaf as main, in recent years also someone begin one's study ramie Sativa Silage Technology and TRM pellet based on numb leaf.But ramie leaf is gathered, cost of labor is too high, and the available blade amount in unit are soil is little, has limited intensive, large-scale production feed.Ramie Sativa Silage Technology has solved local use problem, but is limited to the water content of ensilage 50%-70%, long-distance transportation high cost.Produce a kind of technology that can utilize ramie whole hemp stalk preparation pellet of being badly in need of, effectively in conjunction with the feature of ramie high yield, high nutritive value with particulate material is balanced in nutrition, good palatability, high, the resistance to storage of conversion ratio, the just advantage of transportation, and then reduce feed grain consumption, promote the sustainable development of plant-eating animal aquaculture.
Summary of the invention
Based on China's current plant-eating animal aquaculture overview and ramie feedization research and development basis, the object of the invention is to develop a kind of plant-eating animal pellet take ramie whole hemp stalk grass meal as major ingredient and preparation method thereof.
To achieve these goals, plant-eating animal ramie feed provided by the invention, comprise following component by weight percentage: 40% ~ 70% ramie grass meal, 8% ~ 20% leguminous forage, 8% ~ 20% graminous pasture or crop material powder, 10% ~ 20% corn flour and/or dregs of beans, 1% ~ 4% premix, 1% ~ 2% molasses, 0.3% ~ 0.5% salt, 1% ~ 2% grease, add up to 100%; Ramie grass meal used is that ramie cauline leaf forms through super-dry, pulverizing.
Described ramie feed is preferably pellet.
Described ramie grass meal preferably cradles overground part in the time that Ramie Growth height is 40 ~ 80cm, is dried, pulverizes and obtain.Or after decorticating peeling, gained cauline leaf is dried, is pulverized and obtains in the time that Ramie Growth height is >80cm.Described dry moisture≤13% that is preferably dried to.
The preparation method of ramie feed for above-mentioned plant-eating animal, comprises the steps:
(1) raw material ramie grass meal, leguminous forage, graminous pasture or crop material powder, corn flour, dregs of beans and salt are pulverized, sieved, average particulate diameter is 0.5 ~ 3mm, mixes, stirs according to formula composition;
(2) add molasses, premix and grease, control mixture moisture content 15% ~ 20%;
(3) be granulation into particulate material;
(4) cooling, dry.
As improvement, also add appropriate antioxidant in step (2).
Step (3) dry be preferably dry to moisture weight percentage be 8% ~ 12%.
Find that after deliberation the ramie nutritional labeling difference of different harvesting heights adopts " No. 2, middle ramie " ramie complete stool nutrition Quality Analysis, in table 1.

Feed of the present invention is suitable for the plant-eating animals such as ox, sheep, rabbit, goose, can effectively reduce the ratio of grain raw material in plant-eating animal daily ration, can, on the basis of maintenance plant-eating animal production performance, significantly reduce grain consumption, and reduce aquaculture cost.Comprehensive nutrition, balanced ration structure, improves digestibility and the feed conversion rate of plant-eating animal, improves daily gain, further improves dressing percentage, shortens the cycle of fattening, reduces the fattening effect of feed grain consumption thereby reach.
The specific embodiment
The present invention's dregs of beans used, grease, molasses etc. can be buied from market.Grease can be edible soybean oil, for example animal fodder oil, sesame oil, peanut oil, ready-mixed oil.Crop material powder can be pulse family, powder of straw gramineous.Component used " 10% ~ 20% corn flour and/or dregs of beans ", can be 10% ~ 20% corn flour, or is 10% ~ 20% dregs of beans, or the mixture of corn flour and dregs of beans, and the two ratio is not had to specific (special) requirements.Premix is the compound premix of vitamin, trace element and mineral matter, has the product of plant-eating animals such as being suitable for respectively ox, sheep, rabbit, goose, and the product being well known to those skilled in the art, can directly buy from the market.Following embodiment compound premix used is according to containing zinc 5000-15000mg in per kilogram feed, iron 8000-75000mg, copper 500-2500mg, manganese is containing 4000-15000mg, selenium 10-50mg, cobalt 20-200mg, iodine 50-1000mg, vitamin A 400-1000KIU, neo dohyfral D3 80-400KIU, the ratio preparation of vitamin E 3 2400 mg.Below be weight percentage.The following stated is only preferred embodiment of the present invention, and the present invention is not construed as limiting.
