Abstract
The present invention provides a kind of PVA for ruminant feed and is coated with slow-release carbamide, includes the following raw material composition of mass percent concentration：PVA2 5%, water 20 50%, urea 45 85%.The PVA coating slow-release carbamide solid particles of the present invention are used to prepare ruminant feed.PVA coating slow-release carbamides solid particle of the present invention has better slow release.
Description
Technical field
The invention belongs to ruminant feed components technical fields, and in particular to a kind of PVA for ruminant feed
It is coated with slow-release carbamide.
Background technology
Ruminant has the activity by microorganism in first stomach and the second stomach, and it is higher that NPN is converted into nutritive value
Microbial body albumen be used in the ability of idiotrophic.Because ruminant has what nonruminant cannot be utilized directly
Ammonium compounds（Such as urea）The ability of available protein is converted into, can in vivo be turned in ruminant so there are many NPN
Change a part for protein feed into.Described NPN compounds in ruminant animal nutrition generally refer to simple compound containing N
Such as urea, allophanamide, ammonium salt, can replace the protein feed of plant or animal origin, and feeding ruminants are to provide synthesis
The required nitrogen source of mycoprotein saves of animal or plant nature protein feed, this be also ruminant and nonruminant difference it
One.
Ruminant is to the utilization of urea by palatability is poor, ammonia rate of release is fast, utilization rate is low, improper use easily poisoning etc.
The limitation of factor.It is very much the reason for utilization rate is caused to decline soon that ruminant cannot efficiently use NPN degrades in cud.Urea
As nitrogen source, hydrolysis rate is comparatively fast asynchronous with substantial amounts of energy feed fermenting speed in cud, and part urea is caused not have
It is synthesized before microprotein utilization, oneself is excreted by cud Absorption And Metabolism, thus utilization rate is not high.Therefore, ammonia is regulated and controled
Rate of release mycoprotein is efficiently translated into ammonia in ruminant tumor gastric with more real meaning.
Slow released urea technology is to supplement the nitrogen source mode that ruminant efficiently uses, and promotes the generation of rumen microorganism and subtracts
Slow poisoning, so as to improve feed intake and digestibility with roughages such as stalks, it is shown that good application prospect facilitates this hair
It is bright：PVA is coated with slow-release carbamide
The content of the invention
The object of the present invention is to provide a kind of PVA for ruminant feed to be coated with slow-release carbamide.
PVA provided by the present invention is coated with slow-release carbamide solid particle, includes the following raw material of mass percent concentration
Composition：PVA2-5%, water 20-50%, urea 45-85%；
The preparation method of the PVA coating slow-release carbamide solid particles of the present invention, including the steps：
1）PVA is added to the water, is heated slowly to 65 DEG C；
2）By step 1）Solution foaming after add in urea, wherein urea fineness is less than 0.5mm；
3）The mixture of step 2) is stirred 35 minutes, is uniformly mixed；
4）By step 3）The mixture of processing is cooled to 20 DEG C；
5）By step 4）Mixture be transported to centrifugal granulator particle be made；
Above-mentioned PVA coating slow-release carbamide solid particles are used to prepare ruminant feed；
Preferably, usage amount of the PVA coatings slow-release carbamide solid particle of the present invention in feed is no more than the 1.5% of daily ration.
The present invention under ruminal environment can stabilizing dissolved 3 it is small when more than, alternative more than 50% protein raw materials.
Specific embodiment
The present invention is described in detail with reference to embodiment.
Embodiment 1
The preparation method of PVA coatings slow-release carbamide solid particle provided by the present invention is as follows：
1）PVA25 kilograms is added in 250 kg of water, is heated slowly to 65 DEG C；
2）By step 1）Solution foaming after add in 1200 kilograms of urea（Urea fineness is less than 0.5mm）；
3）The mixture of step 2) is stirred 35 minutes, is uniformly mixed；
4）By step 3）The mixture of processing is cooled to 20 DEG C；
5）By step 4）Mixture be transported to centrifugal granulator particle be made；
Solubility experiment is carried out, experimental result is as shown in table 1；
Table 1：Solution rate of the variety classes urea in 25 DEG C of water
The above results show that the PVA coating slow-release carbamide solid particles of the present embodiment have better slow release.
Embodiment 2
The PVA coating slow-release carbamide solid particles of preparation are added in milk cow forage to feed
The milk cow forage wherein used can be conventional dairy cow forage formula, and a kind of concrete composition is as follows：Tall oat grass 1kg,
PVA coatings prepared by 4 kg of clover, 1 kg of cottonseed, 8 kg of concentrate supplement, 6 kg of brewex's grains, 18 kg of ensiling, embodiment
Slow-release carbamide solid particle 2kg
Control group dairy cow forage formula is as follows：
Tall oat grass 1kg, 4 kg of clover, 2 kg of cottonseed, 9 kg of concentrate supplement, 6 kg of brewex's grains, 18 kg of ensiling,
For using effect, the results are shown in Table 1：
Table 2：The using effect table of embodiment and control group dairy products
Note:Foundation cattle experimental group 300, control group 278, milk yield is average milk production
As can be seen from the above table, adding PVA coating slow-release carbamide replacement concentrate supplements and cottonseed reduces feed cost, to ox
The yield and quality of milk does not have an impact.
