Description

Huge legendary turtle is closed the production method that encapsulates the slowly-releasing protein feed

Technical field the present invention relates to a kind of production method of SRNPN Nonprotein nitrogen feed.

Background technology China is the country of a protein feeds shortage; Along with Developing of Animal Industry; Especially animal husbandry " drylot feeding stable breeding " " seals to prohibit and herds ", and with regard to food security, feed safety and animal husbandry development, the conventional feed raw material can not satisfy the needs of aquaculture far away.Especially the demand gap to protein feeds strengthens year by year.In ruminant feed, effectively utilizing in the vegetable protein feed, strengthen the research and development application to the SRNPN nonprotein nitrogen, is to alleviate the not enough effective way of protein raw material.

Just begin to use nonprotein nitrogen in the Domestic Animal daily ration as far back as 19 th Century German, the sixties in 20th century, country such as the U.S., Japan, former Soviet Union used nonprotein nitrogen in the Domestic Animal feed in succession.The eighties in 20th century, China's minority area began to utilize urea to be that nitrogenous source comes exploratory feed beef cattle sheep and milk cow, all failed to apply because of reasons such as poor stability, utilization rate are low.20 end of the centurys, the proposition of " ruminant tumor gastric ability nitrogen is theoretical " was that the scientific and reasonable nonprotein nitrogen that utilizes provides scientific guidance; Country organizes science and technology strength that feasibility study has been carried out in effective utilization of nonprotein nitrogen during " eight or five "; Effect is distinguished and in national extensive use, reaches advanced world standards through the several generations technology innovation at present.

Is what principle the mechanism of action: it that the ruminant tumor gastric microorganism utilizes SRNPN (sustained-release non-protein nitrogen)? Microorganism (bacterium and ciliate) can be decomposed into little molecule ammonia nitrogen class material with protein in the feed in ruminant (ox, sheep, camel, the deer etc.) cud; Under the condition of energy abundance, ammonia nitrogen class material is converted into mycoprotein through the growth of microorganism breeding; Because the SRNPN feed is merely animal the ammonia nitrogen source is provided, rather than protein directly is provided.The cud of ruminant works the effect of hoarding food, and does not have digestive function; The protein major part that ruminant absorbs is not directly provided by feed, but utilizes microbial bacteria body protein and synthetic protein after transforming to digest and assimilate.Other animals are simple stomach, and micro organism quantity is few, and gastric digestion protein is from feed, to absorb, and can not utilize the ammonia nitrogen synthetic protein, so the SRNPN feed can only be used for feeding ruminant and the nonruminant of can not feeding.

Use the common urea cattle and sheep of feeding to cause ammonia poisoning; Mainly be because urea discharges too fast in cud; Fertilizer is water-disintegrable too high with urea concentration, explosive ammoniacal fermentation can occur after feeding, and produces a large amount of gases; The local action of ammonia causes the infusorian mortality of synthesising thalli protein matter in the cud, and microbial population is out of proportion; Simultaneously also having stimulated the coat of the stomach mucous membrane to cause necrosis comes off; A large amount of ammonia nitrogens gets into blood, in liver, can not fully detoxify, and along with blood gets into brain tissue, blocks nerve cell energy circulation and respiration process, has a strong impact on the production performance of animal, even threat to life.

SRNPN is the english abbreviation of sustained-release non-protein nitrogen Sustained-release non-protein.Close and encapsulate slowly-releasing and handle through NPN being carried out special huge legendary turtle, urea analog derivative hydrolysis ammonia is discharged slowly, ammonia concentration is constant relatively, maintains the low concentration state, is easy to microbial fermentation and decomposes.For the rumen microorganism growth provides suitable condition, thereby reach the purpose of effective utilization.

Summary of the invention the objective of the invention is: provide a kind of huge legendary turtle to close the production method that encapsulates the slowly-releasing protein feed.

Technical scheme of the present invention is: by weight percentage, with urea 33-37%, carrier 28-32%, mix; Get in the dissolving modulator, under 0.4-0.6Mpa pressure,, get rid of ammonia simultaneously continuously through the dissolving modulator; Get into cooler and carry out adding talcum powder 28-32% behind the cool drying, mix the back and pulverize, form the micropill graininess this moment with the high speed atomizer; Get into mixer again; In mixed process, spray into the corn syrup 6-8% that contains sugared 70-75%, carry out the drying back and add ruminant special composite enzyme 0.1-0.3%, get final product packed products after mixing again.

Carrier is one of any or their composition of maize cob meal, talcum powder, powdered rice hulls or cavings.

By weight percentage; Urea 35%, maize cob meal 12%, zeolite powder 14%, the powdered rice hulls 4% of nitrogen content 46% are mixed; Material get into the dissolving modulator under 0.6Mpa pressure continuously through modulator and get rid of ammonia, get into cooler and carry out adding 200 order talcum powder 28% behind the cool drying.Mix the back and pulverize, form the micropill particle, get into mixer again, in mixed process, spray into the corn syrup 7% that contains sugar 75%, carry out the drying back and add ruminant special composite enzyme 0.2%, get final product packed products after mixing again with the high speed atomizer.

Advantage of the present invention is:

1., increase operation rate and impel energy feed to absorb;

2., slowly be released to microbial reproduction at ruminant tumor gastric nitrogenous source is provided;

3., safety, can reduce protein in the feed (grain) consumption 5%-8%;

4., increase consumption 2%-3% than common urea;

5., can not produce ammonia poisoning.
