Ruminant high energy straw feed of the present invention adopts said method production to make.
Owing to taked the distinctive method of the present invention, to handle the stalk that obtains and organize complete decomposition, even, the stalk outward appearance after the processing obviously changes, stack volume-diminished, stalk shape thing reduces, and major part all becomes floccule, bulk softness, impel the cellulose cell to tear, cell membrane is loose, thereby has changed the structure of coarse-fibred overall structure and strand in the stalk, cellulosic molecule fracture, lignin fusing helps microbial degradation and has improved the performance that mixes with unclassified stores.
Find by electron microscope observation, stalk cell marshalling before handling, eucaryotic cell structure is complete, and cell membrane (its main component is a cellulose) is being wrapped up in cellular content; Stalk cell after the processing is destroyed, and cell membrane is torn and become wadding fibrously, and iuntercellular is apart from widening, soft edge, and cellular content dissociates out, improves straw utilization rate and application greatly.
Stalk among above-mentioned each embodiment comprises the stalk of various crops such as wheat, corn, paddy rice, cotton, Chinese sorghum, rice husk, peanut shell, corncob, branch, leaf, sawdust, shell, potato class and beans, and the body of rod of plant such as weeds, reed, branch, leaf.
Ruminant high energy straw feed of the present invention, it is the high-tech product of a kind of " low fat; non-grain fodder ", by oxidation implosion technology, destroy lignin, utilize the bioactivator of the special pearl of straw again, excite a large amount of breedings of microorganism, produce a large amount of mycoprotein (animal is absorbed in more than 80% mycoprotein) and amino acid, the high-efficiency feed that is composited with partial supplementary material again, so not only cost is low for it, also the be highly advantageous to absorption of animal of nutritive value wherein, and the mixed feed on the market is a kind of grain feed of being made by smart grain more than 60% and additive etc., its cost is very high.Adopt stalk to produce high energy feed; for poultry scale, industrialized aquaculture provide best easy approach, help developing the breed cause and make energy resource consumption; reduce feeding cost; simultaneously can allow the stalk that arbitrarily abandons or burn become commercial energy, bring directly to the peasant to increase income, cultivate 5 mu of ground with the each household peasant; plough for every mu and produce 1 ton of stalk; stalk per ton is sold 350 yuan of calculating, can increase income in each household year 1750 yuan, helps improving people in rural areas' living standard.
Ruminant high energy straw feed of the present invention, the animal that searches for food easily digests, price of deed rate height.Because the complicated organic matter degradation that processing procedure allows the livestock and poultry such as crude fibre of stalk be difficult to absorb is the easy small-molecule substances such as monose, disaccharide and amino acid that absorb, and has improved the digestive utilization ratio of agricultural crop straw greatly.Its project indicator: crude fibre 15.21%, crude protein also improve price of deed rate 10-20% simultaneously greater than 15%.Because good palatability, animal feed intake is big, and the livestock and poultry resistance against diseases is improved, and has opened up wide space for nonruminant utilizes straw feed.
Ruminant high energy straw feed production process of the present invention is simple, and production capacity is big, the efficient height, and raw material is extensively easily purchased, and production cost is low, less demanding to instrument and equipment and operator quality.The multiple effective way of utilizing agro-ecology mass-energy source to use combines, strengthening the stalk high-energy efficiency low energy consumption transforms, strong to the straw feed palatability after handling, the fiber degradation rate can reach 20%-35%, protein content increases more than 50%, and contains several amino acids, can replace the concentrated feed of 40%-50%, the livestock and poultry such as pig, ox, chicken, duck, fish that are used to feed have reduced the 30-60% aquaculture cost.
The enforcement of ruminant high energy straw feed of the present invention also can realize the efficient utilization to waste resource, to satisfy the requirement of environmentally safe discharging, energy conservation and environmental protection benefit is good, can increase peasant's income, effectively improve the life of farmers level of poverty-stricken area,, promote China's sustainable development of animal husbandry to have important function optimizing energy resource structure, meaning is very great, meets the energy and the environmental protection policy of country.
Adopt the processing method of ruminant high energy straw feed of the present invention, not only can be to the stalk of corn, wheat, paddy, cotton, shell, potato class and the beans of crops processing and utilization in addition, the weeds of the Nature growth, reed, branch, leaf etc. also can utilize the present invention to be processed into and be feed.
Embodiment recited above is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the spiritual prerequisite not breaking away from the present invention; various distortion and improvement that the common engineers and technicians in this area make technical solution of the present invention all should fall in the definite protection domain of claims of the present invention.
