Description
Technical field
The invention provides a kind of compound feed and production method thereof that contains controlled release chemical fertilizer, particularly contain the compound feed and the production method thereof of long-acting ammonium carbonate or urea.
Background technology
The cellulose part that contains in the straw can be by ruminant digestibility and utilizations such as cattle and sheep, and the lignin part then substantially can't be by digestibility and utilization.And the main effect of ammonification is to utilize ammonia and stalk generation ammonolysis reaction, destroys the ester bond that connects between lignin and the polysaccharide, makes digestive enzymes contact with it easily, thereby has improved the enzymolysis speed of stalk, promotes the digestibility of stalk.Nonprotein nitrogen in the ammoniated straw can need for the microbial metabolism in the cud, promotes the synthetic of microbial body protein.After these microbial bodies that contain albumen enter small intestine, under the effect of various digestive ferments, rumen bypass protein in feed can be absorbed by ruminant, the efficient that microorganism in the cud absorbs the nonprotein nitrogen synthetic animalcule albumen can reach 80%-90%, so that ammoniated forage is fattened meaning to the raising of cattle and sheep is very big.The nitrogenous source that the ammonification processing is added can be considered and increased thick protein in the feed.
The used ammonia source of ammoniated straw mainly contains liquefied ammonia, ammoniacal liquor, urea, carbonic hydroammonium and people and animals' urine etc. both at home and abroad at present.And suitability for industrialized production multiselect urea and carbonic hydroammonium, but because of the volatile loss of carbonic hydroammonium, generally the volatilization loss amount of ammonia can reach 25%-35% in the high temperature ammonifying process.
The raw material of ammoniated straw, nearly all agricultural crop straw all can be made the ammonification raw material, and the purpose that ammonification is handled is to improve the nutritive value of stalk, and the stalk quality is poor more, and the amplitude that improves through nutrition after the ammonification is just big more.And for the stalk good palatability, the forage grass that is of high nutritive value can do ammonification and handle.Content of lignin such as general cornstalk, wheat-straw, straw are higher, all should carry out ammonification to handle; And for the beans stalk, herbage, crops leftovers that sugar content is higher and the various higher cottonseed cake of protein content, soya-bean cake, the rapeseed cake etc. of containing can not done the ammonification processing.But ammoniated straw forage grass because the ammonia flavor is big, and makes the cattle and sheep apocleisis.
In addition, urea belongs to Nonprotein nitrogen feed.As far back as World War I period, because feed lacks, protein feeds wretched insufficiency especially, impel people to begin one's study utilization that nonprotein nitrogen raises at sheep, ox ruminant domestic animal.To just having affirmed that early in the twentieth century urea can replace a part of protein in ox, the sheep daily ration, to mid-term in 20th century urea be commonly flourishing cowboying country as feed and used, in the nutritional feed additive a class is listed it by the U.S.; Class of forage protein raw material in is listed it by Germany; U.S. feed nonprotein nitrogen year consumption figure is about 820,000 tons.And China also begins to pay attention to the problem of utilizing of nonprotein nitrogen in feed research.Along with the development of China's aquaculture and feed processing industry, protein feeds is more and more nervous, reaches 1,200 ten thousand tons according to the annual shortage of measuring and calculating, raises ruminant such as cattle and sheep and is significant so exploitation is the nonprotein feed of representative with urea.The molecular formula of urea is (NH
2)
2CO, the nitrogen content of urea is 46.67%, the protein nitrogen content of 1 kg urea is equivalent to the content of 7 kilograms of protein nitrogens in the soya-bean cake approximately, the market price of the 1 kg urea then price with 1 kilogram of soya-bean cake is suitable, then we can say and utilize a part of urea replacement soya-bean cake can reduce the cost of feed greatly, improve the market competitiveness of beef milk.
The approach that utilizes of its urea is, enter the cud of ox when urea after, in cud under the effect of urase, can resolve into amido formic acid ammonia, further be decomposed into carbon dioxide and ammonia, ammonia is utilized by microorganism in the cud, but the protein of synthesized micro-organism---mycoprotein itself, after these mycoproteins enter small intestine, utilized by ruminant (ox, meat) again.But, ox, sheep raise urea instead of part protein concentrated feed so feeding.But because urease activity is very strong in the cud, the amount that the ammonia that is decomposed to form is often utilized greater than Institute of Micro-biology in the cud, just the urea speed that decompose to produce ammonia in cud under the urase effect is utilized fast several times of the speed of ammonia than rumen microorganism, part ammonia is excreted, or closely go into blood and cause ammonia intoxicating phenomenon.So long-term test results thinks, the use amount of urea fodder can not surpass 2% of total solids in the daily grain, and is exactly that 2% urea is fed the amount of raising, and the decomposition utilization rate of ammonia also only has 50%-60%, has about 40% can not be utilized by Institute of Micro-biology.So study both at home and abroad the problem of utilizing of raising urea nonprotein nitrogen always, acquired progress is to make to mix in the fine fodder behind the plastered starch urea to use again.
