Abstract
The present invention relates to non-protein nitrogen slow-release feed suitable for ruminant, and a production method thereof, more specifically to slow-release feed with carbamide and starch, and a production method of the feed. The product of the present invention is mainly prepared from corn, carbamide and slow-release agents. The present invention has the advantages that during processing, because of the combined action of gelatinized corn coating o the carbamide, and the slow-release agents, the carbamide can not be quickly decomposed under the condition of heating and adding water, and can not generate abnormal odor, and many years experiment research shows that 5 to 10% of the product of the present invention is added into the concentrated supplement feed for ruminant such as cattle and sheep, the crude protein provided by the carbamide can account for 39% of crude protein of rations, and thus, the deficiency of protein feed is effectively relieved.
Description
Technical field:
The present invention relates to a kind of non-protein nitrogen retardative-released fodder of ruminant and method of production thereof of being applicable to, more particularly about a kind of released fodder of urea and starch and a kind of method of producing this feed of containing.
Background technology:
Nonprotein nitrogen such as urea are to have the industrial output height, price is low, the advantage that nitrogen content is high, urea nitrogen content about 46%, the home and abroad achievement in research shows that ruminant (for example cattle and sheep) has and a kind ofly utilizes that microprotein synthesizes the characteristic of nonprotein ammoniac compounds (for example urea) in its stomach of ruminants, thereby can use compound as protein.Though the urea as the nonprotein nitrogen compound can not provide heat, minerals and vitamins, because it contains the high protein equivalent, it can become a kind of good protein source.Therefore, compared by the situation that expensive plant animal protein feed (as big dregs of beans, the cottonseed dregs of rice, fish meal, digested tankage, blood meal) provides with the desirable proteins quality, the most handy certain amount of urea substitutes the required albumen quality of ruminant.
Yet above-mentioned urea can cause a kind of dissolution phenomena excessively in stomach of ruminants, thereby can increase the concentration of ammonia greatly.Consequently, though in the synthesizer body protein, used microorganism, owing to absorbed quite a large amount of ammonia in the ruminant body, thereby exist the problem of ruminant ammonia poisoning.
Up to now, this useful but urea tool danger only is used for simple feed on a small quantity, fail to bring into play due effect.
Summary of the invention:
The problems referred to above that the object of the invention just is to eliminate in the previous method is met provide a kind of high urea-containing slowly-releasing protein feeds (can prevent ammonia poisoning and increase its serviceability in body) and the method for producing this feed.The present invention studies show that, by supplying with required energy and other nutritional labeling of synthesized micro-organism in the cud, can speed improve in the cud microorganism to the synthesis of protein, and the reduction of urea solvent speed can prevent ammonia poisoning, thereby increase the usability of body feed.
The object of the invention realizes being realized by following technical scheme:
Product of the present invention mainly is made up of corn, urea, sustained release agent, wherein: corn 65-85%, urea 10-30%, sustained release agent 5-10%; Sustained release agent mainly is made up of ferrous sulfate, copper sulphate, Sodium Metabisulfite, bentonite or zeolite powder; Wherein: ferrous sulfate 2-5%, copper sulphate 5-10%, lay particular stress on sodium sulphite 3-5%, bentonite or zeolite powder 70-80%.
Product processes of the present invention is, urea (nonprotein nitrogen material) and starch based cereal (as corn etc.) are prepared burden in proportion and pulverize after the screen of 3mm, premixed, adding sustained release agent more further mixes, form pre-expanded material, afterwards, go into general bulking machine through expanded, swelling temperature is 130-140 ℃ of scope;
After expanded, make urea evenly be adsorbed in the corn flour composition, formation physical chemistry bonding is gelation state, and partial reduction sugar and urea form chemical bond, produce the allophanamide reflection between a spot of urea molecule, ruminant is searched for food behind this feed, and urea slowly discharges equably, and urease inhibitor can suppress the activity of urase, the ammonia rate of release slows down, thereby brings into play feeding value safely and effectively.
Advantage of the present invention is, in process since the gelatinization pone by the acting in conjunction of urea and sustained release agent, urea is in heating and add under the situation of water not can very fast decomposition, do not produce peculiar smell, prove through experimental study for many years, add the product of the present invention of 5-10% in the smart feed supplement of ruminant (for example ox and sheep), the thick protein that urea provides can account for 39% of daily ration thick protein, alleviates the shortage of protein feeds effectively.
Accompanying drawing 1 is technological process of production figure of the present invention;
Below in conjunction with accompanying drawing feature of the present invention and correlation technique feature thereof are described in further detail;
The present embodiment product mainly is made up of corn, urea, sustained release agent, wherein: corn 65%, urea 30%, sustained release agent 5%; Sustained release agent mainly is made up of ferrous sulfate, copper sulphate, Sodium Metabisulfite, bentonite or zeolite powder; Wherein: ferrous sulfate 5%, copper sulphate 10%, Sodium Metabisulfite 5%, bentonite or zeolite powder 80%.
Show that as accompanying drawing 1 product processes of the present invention is, urea (nonprotein nitrogen material) and starch based cereal (as corn etc.) are prepared burden in proportion and pulverize, with the material after pulverizing through the screen of 3mm (if granularity is excessive, material is difficult for ejection, and the while corn mixes inhomogeneous with urea liquefaction, influence product quality, material is easy viscous in machine), add 5% sustained release agent again and further mix, form pre-expanded material, afterwards, go into general bulking machine through expanded, swelling temperature is 130-140 ℃ of scope; Expanded material, through the heating of pressurization material, though molten condition, the material of ejection are rare soft strip, need moment to ventilate and cool off, set up cutter at spout, it is granular that material is cut into certain-length, enters rotation air draught type cooler and thoroughly cool off, and strengthens hardness, go into pulverizer then and pulverize, as finished product packing.
After expanded, make urea evenly be adsorbed in the corn flour composition, formation physical chemistry bonding is gelation state, and partial reduction sugar and urea form chemical bond, produce the allophanamide reflection between a spot of urea molecule, ruminant is searched for food behind this feed, and urea slowly discharges equably, and urease inhibitor can suppress the activity of urase, the ammonia rate of release slows down, thereby brings into play feeding value safely and effectively.
Main test data:
1. by the cud evidence, the rate of release of urea ammonia is lower by 30% than common urea in the non-protein nitrogen retardative-released fodder, and is similar to the rate of release of soya-bean cake ammonia.
2. with the evidence of fistula sheep and ox, the efficient that non-protein nitrogen retardative-released fodder ammonia is converted into rumen microorganism nitrogen is more than 90%.
