2. Description of the Related Art In recent years, milk production among dairy cows has been increasing year by year due to genetic improvement and advancement of feeding management technology. Lactation has traditionally required a large amount of energy, and in general, the production of one kilogram of milk requires around 1.5 Mcal of energy (net lactation energy). Therefore, in order to satisfy the energy requirement corresponding to the increase in milk production, using cereals such as corn or barley, which are considered to have relatively high energy, or using raw materials having a high fat content such as soybeans or cottonseed. Attempts have been made to prepare feed for feeding.

[0003] However, there is a problem in the rumen function and the physiology in the large supply of these feed materials, and the supply amount is limited. In other words, polysaccharides such as starch are rapidly fermented and decomposed in the rumen to produce a large amount of volatile fatty acids, so that the pH of the rumen drops sharply, causing acidosis, and causing a large supply of cereals. Vegetable oils and fats served as containing feed contain large amounts of unsaturated fatty acids,
This is decomposed and released by microorganisms in the rumen, causing problems such as filming other feeds or killing microorganisms living in the rumen. In addition, even in individual dairy cows, there is a limit in feed intake depending on the milking period, and the actual current situation is that energy is insufficient.

[0004] In order to solve the energy shortage caused by such problems, palm oil or rapeseed oil is currently used in C.
Fatty acid salts (saponified fats and oils) produced by a saponification reaction with monovalent or divalent metal ions such as a ²⁺ , Mg ²⁺ , Na ¹⁺ and K ¹⁺ are used as high-energy feed. ing. In general, in these fatty acid salts having a large amount of fatty acid calcium of Ca salt, bound metal ions prevent release of unsaturated fatty acids contained in vegetable oils such as palm oil or rapeseed oil in a large amount in the lumen. It is not expected to have an adverse effect on the microorganisms that live in the country.

[0005] However, such fatty acid metal salts (fatty acid calcium) contain the metal salt itself which is not involved in the increase or decrease of energy at all, and further contain water generated during the binding reaction between the fatty acid and the metal ion. In terms of ratio, there was a problem that the absolute amount as energy was reduced by about 15% as compared with the fatty acid. In addition, there is a problem that the palatability further deteriorates because the fatty acid originally having poor palatability further contains a metal ion having poor palatability. In addition, even when mixed, the fatty acid metal salt (for example, fatty acid calcium, etc.) is in the form of granules having an average particle size of 2 mm or more, whereas most other biologically active substances are powders of 1 mm or less. In such a stirred mixture, there is a problem that the dispersion of the biologically active substance is not uniform, resulting in a bias.

On the other hand, in solving these problems,
According to a mixture of the above-mentioned biologically active substance and other substances having good palatability using a powdered product of a fatty acid having a particle diameter of 1 mm or less as a raw material, dispersibility and palatability as a whole are obtained. The effect of improvement can be expected to some extent. However, mere agitation or mixing alone increases the contact area with air, which facilitates the oxidation reaction, degrades the quality, or causes biologically active substances due to rumen endogenous microorganisms in rumen physiology and function. Since it is decomposed, there is a problem that it is not effectively used. In addition, even if an attempt is made to solve the above-mentioned problems by subjecting these agitation and mixture to granulation processing, fatty acids are melted due to frictional heat generated during the granulation step, and granulation becomes impossible. .

[0007]

DISCLOSURE OF THE INVENTION In view of the above problems and disadvantages, the inventors of the present invention have proposed a method for stabilizing the supply of deficient energy and other nutrients in dairy and beef cattle to the extent possible, The content was increased, and a simple granulation process was performed to obtain a high-energy mixed feed. As a result, the present inventors have found that a mixture containing a specific proportion of free aliphatic monocarboxylic acid, a water-soluble metal salt, a crude fiber feed and an adsorbent, a biologically active substance, and a feed material are contained. By mixing and granulating by uniform stirring and mixing, the content of fatty acids is increased as much as possible, and it is possible to stably granulate and pelletize the mixed feed by simple granulation treatment. I found it.

Further, the present inventors have disclosed that at least 50% by weight of one or more of a mixture of straight-chain saturated or unsaturated fatty acids having 14 to 22 carbon atoms is contained. 1/10 or more water-soluble metal salt and crude fiber feed,
Even if the adsorbent of 1/20 or more is stirred and mixed and then subjected to granulation molding treatment, it is melted and eluted by frictional heat generated during granulation, and the adverse effect on the granulation by the liquefied fatty acid is excluded. It has been found that a pellet preparation having a high strength can be obtained with a high recovery rate. Furthermore, when an aliphatic monocarboxylic acid is used in a mixture, the palatability and the fatty acid content of the mixture are adjusted by preparing an unsaturated aliphatic monocarboxylic acid and a saturated aliphatic monocarboxylic acid in a specific ratio. It was found to be superior in terms of its absorption and utilization in the digestive tract after the duodenum. According to the present invention, in the pellets obtained by such a production method, the biologically active substance is decomposed into microorganisms in the lumen by a process of only stirring and mixing of the powder, and is effectively used in the digestive tract after the duodenum. It has been found that the problem of not being used for absorption and the problem of storage such as acceleration of oxidation by air contact can be solved. The present invention has been completed from such a viewpoint.

Conversely, the mixing ratio of free fatty acids is 8
If it exceeds 0% by weight, it is not preferable because sufficient strength necessary for granulating and maintaining a pellet state cannot be obtained, resulting in a decrease in strength.

The water-soluble metal salt used in the present invention includes sodium salts, potassium salts, calcium salts, magnesium salts and the like. Specifically, for example, calcium salts such as calcium hydroxide, calcium carbonate and calcium lactate And potassium salts such as potassium chloride.

When the amount is less than the weight%, a pellet preparation having appropriate strength cannot be obtained at a high recovery rate, which is not preferable. Conversely, if the blending ratio of the crude fiber feed exceeds 10% by weight, it is not desirable in terms of pelletizing a high energy mixed feed containing a biologically active substance, which is one of the objects of the present invention.

The adsorbent used in the present invention is a pulverized product of a porous natural mineral such as zeolite or silica or a pulverized product of a porous compound.

It is 15 parts by weight, more preferably 12 to 13.5 parts by weight. Further, when the mixture contains palmitic acid, oleic acid, or the like as free fatty acids, it is preferable to use lysine, methionine, threonine, tryptophan, vitamin E, or the like as the biologically active substance.

The feed material used in the present invention refers to a nutrient source for a living body or a substance useful for treating or preventing a disease, and commonly used feed materials can be widely used. Specifically, for example, sake bran,
Rice bran and the like can be mentioned, and these raw materials can be used alone or in combination of two or more, and in any case, can be used as a feed raw material. In addition, the mixing ratio of the feed raw material to the mixed feed granulated product of the present invention can be appropriately selected from the mixing ratio suitable for the purpose, and is not subject to any limitation. From the viewpoint of obtaining a feed, the amount is preferably 1 to 5 parts by weight, more preferably 2 to 3 parts by weight, based on 100 parts by weight of the mixture containing free fatty acids. The animal to which the mixed feed granulated product of the present invention prepared from such a composition is to be fed is not particularly limited, but, for example, has a stomach such as a dairy cow, and is not suitable for productivity. It is especially effective for livestock that may have a shortage of energy.

Next, the method for producing the high-energy mixed feed granulated product containing fatty acids of the present invention will be described. The production method of the present invention comprises the steps of: 50 to 80% by weight of a linear aliphatic monocarboxylic acid having 14 to 22 carbon atoms released; 5 to 10% by weight of a monovalent or divalent water-soluble metal salt; Supply 5-10
A mixture containing 2% to 5% by weight of an adsorbent, at least one or more biologically active substances, and feed materials is stirred, mixed, and granulated.

In the production method of the present invention, first, a mixture containing the free fatty acids and the like in a specific ratio, at least one or more biologically active substances, and a feed material are uniformly stirred and mixed. Here, the above mixture contains 50% by weight or more of free fatty acids, and the weight ratio is 1/10
The above water-soluble metal salt and crude fiber feed, and furthermore, 1/2
It is necessary to contain zero or more adsorbents. That is, in the present invention, a mixture containing 50 to 80% by weight of a free fatty acid, 5 to 10% by weight of a water-soluble metal salt, 5 to 10% by weight of a crude fiber feed, and 2 to 5% by weight of an adsorbent is used. .
If the powder mixture is granulated at such a specific mixing ratio,
It can be excluded that the mixture melts and elutes due to frictional heat generated during granulation, and adversely affects granulation due to liquefied fatty acids.

Next, the obtained powdery mixture is subjected to a granulation molding treatment. The granulation of the powder mixture can be performed by a wide range of conventional granulation methods, and is not particularly limited. Specifically, it can be processed by, for example, a generally used extrusion granulator.
The processing conditions are also not particularly limited, and can be appropriately changed according to the composition of the powder mixture and the like. However, the processing is preferably performed at 75 ° C. or lower. On the other hand, if the temperature exceeds 75 ° C. for granulation (pelletization), the production rate (yield) may decrease due to the outflow of oil components (free fatty acids and the like), and the decomposition of the active ingredients may occur, which is not preferable. . According to the method for producing a mixed feed granulated product according to the specific composition of the present invention, a mixed feed can be obtained at a high recovery rate as a pellet preparation having appropriate strength.

That is, during granulation, it is difficult to pelletize only oil components such as free fatty acids, so that the production rate (yield) is reduced, the strength of the granulated product is also reduced, and a favorable mixed feed cannot be obtained. . Therefore, in the present invention, a water-soluble metal salt is included as an essential component in addition to the oil component in order to facilitate the granulation (pelletization) process and improve the production rate. As a result, according to the production method of the present invention, pelletized mixed feed granulated products can be efficiently obtained, and excellent effects such as an increase in mechanical strength of the obtained granulated products are exhibited. Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.
