Abstract
The present invention discloses one kind of non-protein nitrogen feed additive for ruminant and its production process. The non-protein nitrogen feed additive has reasonable recipe, easy production, low cost, high decomposition speed, urea decomposing speed matching the utilization speed of rumen to avoid ammonia accumulation in blood and good taste. The non-protein nitrogen feed additive consists of urea 35-50 wt%, corn starch 35-48 wt%, and coating material 2-20 wt%, and its production process includes the steps of dispersing urea and corn starch in coating material solution, grinding in a colloid mill to form emulsion, and spray drying at normal temperature to form microspherical feed additive. It may be also produced into powder, granule, tablet or capsule.
Description
Technical field
The present invention relates to a kind of Nonprotein nitrogen feed additive and production method thereof that is applicable to ruminant, belong to technical field of animal.
Background technology
Utilize microorganism in the ruminant tumor gastric can utilize the characteristic of ammonia, the normal nonprotein nitrogen of using replaces protein feeds in the ruminant feed, to save protein resource.Urea has nitrogen content height, advantage that production cost is low, under the high situation of animal/vegetable protein feed resource deficiency, price, is the nonprotein nitrogen source that is worth very much deep development.Show that after deliberation urea fodder can make the quick growth and breeding of cattle and sheep rumen microorganism, the back cattle and sheep of feeding can obviously increase feed intake forage grass 15～20%, improve digestibility 20%.General milk cow increases day by day and suckles 5～10%, improves butter fat rate 0.1～0.3%.The nitrogen content of urea is 46%, if can effectively be utilized calculating by milk cow by nitrogen in the urea 70%, 1 kilogram of urea can provide the protein that is equivalent to 4.5 kilograms of soya-bean cakes.According to external, in the daily ration of protein deficient, add 1 kilogram of urea, the 6-12 kilogram of can voluminously suckling; Also obtain 1 kilogram of urea at home and exchanged the effect that the 3.6-4.2 kilogram is suckled for.Yet urea enters just hydrolysis rapidly behind the cud, has ammonia to discharge at once, enters blood by cud, and its rate of release often surpasses the speed of utilizing of microorganism in the cud, just causes the animal ammonia poisoning when the ammonia amount that enters blood surpasses the liver detoxification ability.And urea has the characteristics of palatability difference, may cause the repulsion behavior of animal.The defective of the equal various degrees of urea class feed product of Ying Yonging can not be properly settled the problem that urea exists in application process in the market, influences urea applying in herding is produced.
Summary of the invention
In order to solve above-mentioned deficiency, the object of the present invention is to provide a kind of Nonprotein nitrogen feed additive and production method thereof that is applicable to ruminant, urea decomposition speed utilizes speed to coordinate mutually with cud in this feed addictive, avoid ammonia in blood, to accumulate and cause ammonia poisoning, solve the shortcoming of urea palatability difference simultaneously.
The present invention solves the technical scheme that its technical problem takes: the invention provides a kind of Nonprotein nitrogen feed additive of ruminant and component of production method thereof of being applicable to, and formulated by following component, (percentage by weight)
Urea 35～50%
Cornstarch 35～48%
Coating material 2～20%
Optional at least a in gelatin, sodium carboxymethylcellulose, ethyl cellulose, PVP, carbomer of coating material wherein or their combination.
The invention provides a kind of Nonprotein nitrogen feed additive of ruminant and preparation technology of production method thereof of being applicable to:
The urea and the cornstarch of actual specific gravity are uniformly dispersed in coating material solution, grind to form emulsion, put at normal temperatures and be dried to microballoon in the spray dryer,, also can be made into powder or granule, tablet, capsule etc. as feed addictive through colloid mill.
The invention has the beneficial effects as follows: the preparation technique that on production technology, adopts ultramicro grinding, microencapsulation and miniature balling-up, urea is made the microballoon of diameter between 40-100um, its rate of release in the animal cud is slowly continued, coordinate mutually with the speed of utilizing of urea, solve the urea too fast problem of decomposition rate in vivo, can effectively avoid the animal ammonia poisoning; Adopt spray drying technology to improve the granulation quality, the gained grain graininess is even, inclusion is abundant, inserts the peculiar taste of the imperceptible urea of animal in the animal feed, is easy to eat.The equal safety non-toxic noresidue of selected coating material can not damage animal body in the metabolic process.In process of production, all operations is all finished under normal temperature condition, can not cause urea to decompose, and reduces the loss of raw material.And in actual production, manufacturer can be as required by further mix, make different dosage forms such as the powder that is fit to needs or granule, tablet, capsule to adding auxiliary materials such as starch in the urea microballoon that makes, improved practicality of the present invention greatly; Be applicable to the feed addictive of ruminants such as ox, sheep.
Description of drawings
Fig. 1 is a kind of Nonprotein nitrogen feed additive of ruminant and preparation technology's flow chart of production method thereof of being applicable to.
The specific embodiment
A kind of Nonprotein nitrogen feed additive of ruminant and component of production method thereof of being applicable to, formulated by following component, (components by weight percent)
Embodiment 1
Prescription: urea 500g, cornstarch 480g, gelatin 20g
Preparation method: urea and cornstarch are uniformly dispersed in gelatin solution, grind to form emulsion, put at normal temperatures and be dried to microballoon in the spray dryer, get product through colloid mill.Also can be made into powder or granule, tablet, capsule etc.
Embodiment 2
Prescription: urea 500g, cornstarch 450g, sodium carboxymethylcellulose 50g
Preparation method: in full accord with embodiment 1.
The clinical practice example: the Nonprotein nitrogen feed additive with manufacturing of the present invention is fed to nearly thousand cow heads in Fu Laer base, Qiqihaer City, Heilongjiang Province and Daqing DORBOD area, beef cattle.None routine domestic animal produces malaise symptoms, and milk production of cow steadily increases, and protein content and dairy fat content are improved in the milk; Beef cattle meat palatability improves.
In the numerous rich animal reproduction technology of grand celebration Co., Ltd, choose 20 of the milk cows of daily ration kind protein deficient.Nonprotein nitrogen feed additive of the present invention added feed.Do not have milk cow malaise symptoms to occur, and all milk production of cow increases, protein content and butterfat percnetage all have increase in the milk.
Because action of microorganisms in the ruminant tumor gastric makes the digestion and metabolism of protein and nitrogen-containing compound have particularity.Feed protein enters has behind the cud 60%～70% protein at first to be degraded to amino acid and ammonia by rumen microorganism approximately.These amino acid and the ammonia part that generate are used for outside the microorganism synthesising thalli protein, and remaining ammonia is absorbed by the cud wall and enters the liver urea synthesis through portal vein with blood.A synthetic urea part turns back to cud through saliva and blood and utilizes, and another part then excretes from kidney.80% bacterium can be with the only nitrogen source synthesising thalli protein of ammonia as growth in the cud, and these microbial body albumen become the proteinaceous nutrient source of milk cow again by digestion and metabolism after entering abomasum and small intestine.
