Description
Technical Field
The invention relates to the technical field of feed addition, in particular to a feed additive for adjusting the intestinal function of cattle and a preparation method thereof.
Background
When feeding ruminants such as cattle and sheep, a certain amount of feed-grade urea is added into feed according to the situation to be eaten by the ruminants, so that the feed is beneficial to the growth and development of the ruminants. The principle is that ciliates exist in rumens of ruminants such as cattle and sheep, have certain utilization capacity for nitrogen elements except feed protein, namely 'non-protein nitrogen' (such as nitrogen in urea), and can synthesize self-body protein by utilizing a certain proportion of non-protein nitrogen. After the ciliates are killed, the dead larva bodies are ground by the rumen and digested and absorbed by the small intestine, and the feed is equivalent to high-quality animal protein feed eaten by ruminants.
But the ruminant has certain limitation on utilizing non-protein nitrogen, firstly, the feeding amount of urea is not suitable to be excessive, and preferably not more than 10 percent of the conventional protein feed; and secondly, the animals cannot be fed with water within one hour before and after the feeding of the urea, or the animals are fed with the green feed rich in a large amount of water, otherwise the urea reacts with the water and is rapidly decomposed to generate ammonia gas, the large amount of ammonia gas enters the liver if being absorbed by the rumen wall, the phenomenon of ammonia poisoning of the animal liver and the whole body is caused, and the animals even die in severe cases.
In production practice, many breeders blindly add urea into feed or drinking water without knowing the feeding technology of urea, and some breeders suffer from urea poisoning caused by improper eating of animals due to poor management of urea or urea solution.
Aiming at the problems, the invention aims to develop the cattle feed additive which has less feeding limitation, causes lower risk of urea poisoning of animals, is more convenient to feed and has higher efficiency and can adjust the intestinal function of the animals.
Disclosure of Invention
In view of the above, the invention provides a feed additive for adjusting the intestinal function of cattle, which has the advantages of less feeding limitation, lower risk of animal urea poisoning, more convenient feeding and higher efficiency, and a preparation method thereof.
The technical scheme of the invention is realized as follows: the invention provides a feed additive for regulating the intestinal function of cattle, which comprises an outer coating, an intestinal function regulator, an inner coating and feed-grade urea, wherein the inner coating is coated in the outer coating, the outer coating is water-soluble, the inner coating is water-insoluble, the intestinal function regulator is filled in an interlayer between the outer coating and the inner coating, the feed-grade urea is filled in the inner coating, and the weight ratio of the intestinal function regulator to the feed-grade urea is (1-3): (1-3).
On the basis of the technical scheme, preferably, the intestinal function regulator comprises a mixed microbial inoculum.
More preferably, the mixed microbial inoculum comprises bacillus licheniformis, lactobacillus plantarum and clostridium butyricum, and the weight ratio of each component of the microbial inoculum is (3-5): (3-5): (1-3).
Still more preferably, the intestinal function regulator further comprises activated carbon, a mixed microbial inoculum 1: 1, uniformly mixing.
On the basis of the technical scheme, preferably, the components of the outer coating comprise 35-40% of polyacrylic resin, 20-25% of hydroxypropyl methyl cellulose and 35-45% of absolute ethyl alcohol according to weight percentage.
On the basis of the technical scheme, the inner coating is preferably composed of water-insoluble dietary fibers, and the water-insoluble dietary fibers comprise one or more of wheat bran powder, corn bran powder, walnut shell powder, kudzu root powder, hericium erinaceus powder, agaric powder, jerusalem artichoke powder and oat powder.
In a second aspect, the present invention provides a method for preparing a feed additive for regulating intestinal function of cattle, comprising the steps of,
s1, fermenting and propagating the strains of all components of the mixed microbial inoculum to prepare a slurry microbial inoculum;
s2 grinding and sieving the feed-grade urea, and then preparing into tablets or granules;
s3, weighing various raw materials according to the weight ratio of the inner coating formula, cleaning and removing impurities, and then uniformly mixing to prepare coating paste;
s4, weighing various raw materials according to the weight ratio of the outer coating formula, mixing and dissolving the raw materials, and uniformly stirring to prepare a coating solution;
s5, uniformly mixing the tablets or granules obtained in the step S2 with the coating paste obtained in the step S3, drying and granulating, uniformly mixing the granulated product with the slurry microbial inoculum obtained in the step S1, drying and granulating again, spraying and coating the granulated product with the coating solution obtained in the step S4, and packaging after drying.
Compared with the prior art, the feed additive for adjusting the intestinal function of cattle and the preparation method thereof have the following beneficial effects:
(1) set up inside and outside parcel of feed level urea and intestinal function regulator through bilayer coating structure, make the outer coating disintegrate and release the intestinal function regulator when the additive gets into the rumen, and the inlayer coating keeps intact, can not release feed level urea in it, avoid its reaction with water to lead to the animal to take place ammonia poisoning, consequently need not forbid drinking water or the green fodder of feeding around the additive of feeding, the restriction of feeding is less, the security is high, it is more convenient to feed, and this product has the nutrition that provides non-protein nitrogen for the animal simultaneously and adjusts the function of animal intestinal, feeding efficiency is high.
(2) The inner layer coating adopts the water-insoluble dietary fiber as the main component, not only can separate urea and water in the inner layer coating, but also can be absorbed and utilized by animals in the subsequent digestion process.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The first embodiment is as follows:
the invention provides a feed additive for regulating the intestinal function of cattle, which comprises an outer coating, an intestinal function regulator, an inner coating and feed-grade urea, wherein the inner coating is coated in the outer coating, the outer coating is water-soluble, the inner coating is water-insoluble, the intestinal function regulator is filled in an interlayer between the outer coating and the inner coating, the feed-grade urea is filled in the inner coating, and the weight ratio of the intestinal function regulator to the feed-grade urea is 1: 1.
wherein, the intestinal function regulator comprises a mixed microbial inoculum and activated carbon, the mixed microbial inoculum comprises bacillus licheniformis, lactobacillus plantarum and clostridium butyricum, and the weight ratio of each component of the microbial inoculum is 3: 4: 1, active carbon and microorganism mixed microbial inoculum 1: 1, uniformly mixing.
The outer coating comprises 40% of polyacrylic resin, 20% of hydroxypropyl methyl cellulose and 40% of absolute ethyl alcohol.
The inner coating is composed of water-insoluble dietary fiber, which comprises one or more of wheat bran powder, corn bran powder, walnut shell powder, radix Puerariae powder, Hericium erinaceus powder, Auricularia powder, Jerusalem artichoke powder and oat powder.
The preparation method comprises the following steps of,
s1, fermenting and propagating the strains of all components of the mixed microbial inoculum to prepare a slurry microbial inoculum;
s2 grinding and sieving the feed-grade urea, and then preparing into tablets or granules;
s3, weighing various raw materials according to the weight ratio of the inner coating formula, cleaning and removing impurities, and then uniformly mixing to prepare coating paste;
s4, weighing various raw materials according to the weight ratio of the outer coating formula, mixing and dissolving the raw materials, and uniformly stirring to prepare a coating solution;
s5, uniformly mixing the tablets or granules obtained in the step S2 with the coating paste obtained in the step S3, drying and granulating, uniformly mixing the granulated product with the slurry microbial inoculum obtained in the step S1, drying and granulating again, spraying and coating the granulated product with the coating solution obtained in the step S4, and packaging after drying.
Example two:
the weight ratio of the intestinal function regulator and the feed-grade urea in the first embodiment is replaced by 2: 1, other conditions were kept unchanged.
Example three:
the weight ratio of the intestinal function regulator and the feed-grade urea in the first embodiment is replaced by 1: 2, other conditions remain unchanged.
The invention is not only suitable for cattle, but also suitable for ruminants such as sheep and the like.
The feed-grade urea and the intestinal function regulator are wrapped inside and outside through a double-layer coating structure, when a ruminant eats the feed containing the additive, the outer coating of the additive particles entering the rumen disintegrates under the action of gastric acid, and the intestinal function regulator in the interlayer is released into the rumen firstly.
Because the inner coating is the water-insoluble dietary fiber, when the ruminant drinks a large amount of water in advance or uses green feed with higher water content, a large amount of water exists in the rumen, and the pH value is close to neutral, the inner coating can not be disintegrated, and the phenomenon that the ammonia poisoning of the animal caused by the fact that feed-grade urea in the inner coating enters the rumen and reacts with the water to form ammonia gas is avoided.
When ruminants ruminate their ruminants, the granules, which are only coated with the inner coating, are chewed finely by the animal along with the feed, whereby the inner coating is crushed or ground, and the feed-grade urea therein, along with the chewed feed, re-enters the rumen and is absorbed by the animal.
Therefore, the additive can be fed to animals together with drinking water or green feed, and does not need to be fed separately, so that the feeding efficiency is improved, and the problem of ammonia poisoning caused by hunger and thirst and water drinking error after the animals eat urea is also avoided; meanwhile, microbial flora entering the rumen not only can play a role in the rumen, but also can enter the intestinal tract of the animal along with the feed through the digestive tract so as to regulate the intestinal tract function and increase the immunity and disease resistance of the animal.
It should be noted that the acrylic resin, hydroxypropyl methylcellulose and absolute ethyl alcohol in the outer coating are the existing common coating components, can effectively relieve the external environment, such as processing temperature, external microorganisms, oxygen and the like, and damage to the intestinal function regulator filled in the outer coating in different degrees, is not only an efficacy protective agent, but also a slow release agent, is beneficial to the absorption in animal bodies, has no toxicity and residue, and cannot cause adverse effects on the health of animals and human bodies.
The microbial agent has the effects of stabilizing and balancing the pH value of the rumen of cattle, indirectly inhibiting the growth of pathogenic bacteria, improving the immunity and disease resistance of animals and enhancing the anti-stress capability, has good adaptability to weak acid environments or anaerobic environments in the rumen and intestinal tracts, and can effectively exert the effect.
The activated carbon uniformly mixed with the microbial agent plays a role of a strain carrier, can be well attached to the rumen wall and the intestinal canal wall, and helps the microbial agent to exert efficacy; meanwhile, the odor of animal excrement is absorbed, the emission of harmful gas is reduced, and the culture environment is improved. And moreover, the intake of a small amount of active carbon does not cause harm or poison to animals, and toxic residues do not exist.
Dietary fiber refers to the total of vegetable food ingredients, carbohydrates and the like which are not digested and absorbed in the stomach and small intestine and which are partially or completely fermented and utilized by microorganisms in the large intestine, and is classified into water-soluble and water-insoluble according to its solubility. It has effects of regulating intestinal function, promoting intestinal peristalsis, and preventing constipation. Therefore, the inner layer coating adopts the water-insoluble dietary fiber as the main component, not only can separate urea and water in the inner layer coating, but also can be absorbed and utilized by animals in the subsequent digestion process. The formula of the water-insoluble dietary fiber is grain byproducts such as wheat bran powder, corn bran powder and the like, and the cost is low.
Experimental methods and analysis of results:
taking the additives of the first to third examples as samples to feed 50 cattle respectively, setting 50 cattle which are not fed with the additives as blank control groups, and feeding the cattle until the cattle reach the marketing standard.
The results show that the cattle fed with the additive sample generally appear 10-15 days earlier than the cattle not fed with the additive, and the cattle treatment rate is obviously lower.
Meanwhile, the cattle early slaughter rate in the second and third examples is lower than that in the first example but is not obvious when the first to third examples are transversely compared; the ammonia poisoning of the cattle in the three examples occasionally occurs, but the cattle in the first and second examples do not have ammonia poisoning, because the specific gravity of the urea in the additive formula is large, the specific gravity of the urea in the formula needs to be controlled when the additive raw materials are mixed, so as to ensure the safety of the product.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
