DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a feed for preventing milk fever. More specifically, the present invention relates to a mineral palatability composition for preventing milk fever having good palatability, comprising a calcium source powder and a viscous polysaccharide and a silicate.

[0002]

2. Description of the Related Art Milk fever (inability to stand before and after childbirth) causes the calcium level in the blood to drop due to the sudden start of secret milk after calving. The number is large, which is a huge economic loss for dairy farmers. Conventional methods for preventing milk fever is intramuscular injection of vitamin D _3, such as the administration of dicalcium phosphate are known. In particular, it has been reported that administration of a calcium source such as dibasic calcium phosphate has a high milk fever prevention effect.

[0003]

However, a preventive method by intramuscular injection of vitamin D ₃ must be performed by a veterinarian, and a method of administering dibasic calcium phosphate is as follows:
Due to poor palatability of dibasic calcium phosphate, it cannot be administered spontaneously, but it is performed by a method of forcibly opening the dairy cow's mouth manually and pouring it with a large amount of water, but it takes time and effort because the cow is rampant There are problems such as poor efficiency.

On the other hand, it is known that a gel is formed when a calcium source and a viscous polysaccharide such as sodium alginate are mixed in the presence of water. Therefore, if it can be administered in the form of a gel containing a calcium source and sodium alginate, it is expected to be an effective administration means. However, for the purpose of preventing milk fever, the concentration of a calcium source such as dicalcium phosphate is increased by several tens of weight. %, The hardness of the gel increases, so that the palatability of dairy cows deteriorates, and the cows become violent and cannot be administered. As such, they do not become a mineral feed composition that prevents milk fever. Therefore, a mineral feed composition for preventing milk fever that can be easily administered by dairy farmers is desired.

[0005]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, in the presence of water,
A gel showing thixotropic (thixotropy) can be obtained by adding a mucous polysaccharide such as sodium alginate and guar gum, and a silicate such as silicic acid and calcium silicate to a calcium source such as dicalcium phosphate, which has poor palatability by itself. It has been found that the gel composition is formed and that the dairy cow prefers to ingest the gel composition without rampage, thereby completing the present invention.

That is, the present invention provides a mineral feed for preventing milk fever, comprising a calcium source and 0.06 to 2% by weight of a mucous polysaccharide and 0.02 to 6% by weight of a silicate based on the calcium source. Composition.

The viscous polysaccharide used in the present invention refers to sodium alginate, guar gum and the like, and these can be used alone or as a mixture, with sodium alginate being particularly preferred.

The calcium source refers to powders such as crab shell, oyster shell, bone meal, monocalcium phosphate, dibasic calcium phosphate, tribasic calcium phosphate, calcium carbonate, calcium lactate, etc., and these can be used alone or in combination. However, dibasic calcium phosphate is particularly preferred. These calcium sources preferably have an average particle size of 30 μm or less, and particularly preferably 3 μm or less. When the average particle size is 30 μm or more, the sedimentation speed is high and a uniform gel is not obtained, which is not preferable.

The silicate used in the present invention refers to a silicate such as calcium silicate or magnesium silicate, or silicic acid itself, and any of them can be used, but silicic acid is particularly preferred. These silicates have an average particle size of 3
It is preferably at most 00 μm, particularly preferably at most 100 μm. When the average particle size of the silicate is 300 μm or more, a gel is formed, but the gel is unstable and each component is separated, which is not preferable.

When the mixing ratio of the mucous polysaccharide is in the range of 0.06 to 2% by weight based on the calcium source and the mixing ratio of the silicate is in the range of 0.02 to 6% by weight based on the calcium source, water is added. Since the contained composition exhibits thixotropy (thixotropic) properties, it becomes a gel in a stationary state, and the calcium source powder does not separate and precipitate. In addition, when this composition is shaken lightly, it becomes a fluid sol and the palatability of the dairy cow is improved, so that the dairy cow can be forcibly administered simply by opening the mouth, thereby preventing milk fever. On the other hand, if the mixing ratio of the viscous polysaccharide with respect to the calcium source is less than the above range, the calcium source powder is separated and precipitated, so that the palatability of the dairy cow is undesirably deteriorated. Further, when the mixing ratio of the mucous polysaccharide and the silicate is more than the above range, the strength of the gel becomes too strong, the fluidity is lost, and the palatability is deteriorated. Not preferred.

If the mixing ratio of each component is within the above range, other components such as amino acids (for example, lysine,
Methionine, etc.), vitamins (eg, vitamin A, vitamin D ₃ , vitamin E, etc.), feed additives such as trace minerals, glycerin fatty acid ester, sucrose fatty acid ester, sorbitan fatty acid ester, sodium polyacrylate, polyoxy An emulsifier such as an ethylene glycerin fatty acid ester and a polyoxyethylene sorbitan fatty acid ester may be added.

The feed composition for preventing milk fever of the present invention can be produced by mixing the above-mentioned calcium source, mucous polysaccharide and silicate by a known suitable means. In addition, when the feed composition for preventing milk fever of the present invention is administered to dairy cows, the mixture comprising the calcium source, the viscous polysaccharide and the silicate is dispersed and mixed in a predetermined amount of water as it is, and the thixotropic composition is obtained. Can be administered as
As another method, the thixotropic composition can be prepared by mixing each powder component with water when used, and then administered to dairy cows.

That is, each component may be mixed with water so that the ratio of the mucous polysaccharide and the silicate to the calcium source is as described above. The amount of water to be added is not particularly limited, but if the amount of water added is too large, it is not suitable for the purpose of calcium supplementation, and if the amount of water added is too small, the gel becomes too strong. 30-9 for the total amount
It is appropriately selected within the range of 0% by weight. Particularly, it is preferable to add at a ratio of 40 to 80% by weight. The order of adding each component to water is not particularly limited, but preferably, a calcium source and a silicate are added to water and sufficiently stirred and mixed, and then the mucous polysaccharide is gradually added and mixed with stirring. It is good to manufacture. The stirring speed may be any as long as the components can be uniformly mixed, and can be usually set at 200 to 1000 rpm. The water temperature at the time of stirring and mixing may be in the range of 0 to 50 ° C., and can be usually performed at room temperature.

Table 1 below shows the feed composition of the preliminary experiment and the characteristics thereof which led to the present invention.

[0015]

[Table 1]

From the results shown in Table 1, when three types of calcium sources such as dibasic calcium phosphate, viscous polysaccharides such as sodium alginate, and silicates such as silicic acid are blended, thixotropic (thixotropic) is found. It was confirmed that the gel shown was formed and the palatability of dairy cows was improved. Next, to see the effects of various mucopolysaccharides and silicates from these facts, using dibasic calcium phosphate as a calcium source,
The test was carried out under the conditions of a calcium source, a viscous polysaccharide, a silicate and a water ratio of 50: 0.1: 1: 48.9% by weight, respectively. Table 2 shows the results.

[0017]

[Table 2]

As shown in Table 2, when the composition contains three kinds of ingredients, a calcium source, a mucous polysaccharide (especially sodium alginate) and a silicate (especially silicic acid), all of them have thixotropy (thixotropic). It is evident that the gels shown form and that the calcium source does not separate and precipitate, yet remains fluid. Further, in order to determine the mixing ratio of each component, a test was performed using dibasic calcium phosphate as a calcium source, sodium alginate as a viscous polysaccharide, and silicic acid as a silicate. The results are shown in Tables 3 and 4
It is shown in the table.

[0019]

[Table 3]

As shown in Table 3, the addition amount of the mucous polysaccharide to the calcium source is suitably 0.06 to 2% by weight, and a gel showing thixotropic (thixotropic) was formed in this range.

[0021]

[Table 4]

As shown in Table 4, the appropriate amount of silicate added to the calcium source is 0.02 to 6% by weight, and a gel exhibiting thixotropic (thixotropic) was formed in this range. As described above, based on the calcium source, 0.06 to 2% by weight of the mucous polysaccharide and 0.02 to 6% of the silicate are used.
By blending the amount by weight, gels exhibiting thixotropic (thixotropic) are formed, and these gels are excellent ones with improved palatability of dairy cows.

[0023]

The feed composition of the present invention thus obtained has improved palatability by the addition of a mucous polysaccharide,
Since dairy cows prefer to ingest, a dairy farmer can easily administer a calcium source that is poor in taste by itself. A major feature of the feed composition of the present invention is that a silicate is added to form a gel showing thixotropic (thixotropic), and each component does not separate for a long time, and has good fluidity. There is a feature. As a result, it can be easily administered from the dairy cow's mouth, so that it is possible to ensure that the calcium source can be ingested without leaving only the part with a poor palatability of the calcium source, and as a result, it is simple and easy to administer. Milk fever can be prevented.
