Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a feed additive for livestock. More specifically, it relates to a feed additive that can be fed to livestock together with feed to improve yield, marbling, carcass grading grade and the like.

[0002]

2. Description of the Related Art In order to maintain the health of livestock and promote their growth,
Various feed additives are used. For example, feed additives that are commonly used are oils, fats, vitamins, minerals, amino acids, etc., which supplement the nutrients that are lacking in the feed,
Alternatively, it is used to improve the digestive absorption rate and enhance the fattening effect. Of the livestock, ruminants are the first
In the stomach, the feed is decomposed by microorganisms and digested in the abomasum, but in the rumen, it does not inhibit the growth of the microorganisms.
Studies are also being conducted on feed additives that have the functionality to be well digested by the digestive organs after the stomach.

As such a feed additive, a feed additive for promoting animal growth using a fatty acid calcium salt or a feed using the same (JP-A-58-47442) is known, and the growth of livestock such as ruminant animals is known. It has been reported that it promotes health care and is effective in maintaining health.

[Problems to be Solved by the Invention] Compared to other countries, the taste of meat is unique in Japan, and so-called marbling meat in which fat is mixed like spots in muscle is preferred.
Such meat is soft and at the same time has a proper amount of flesh. Conventionally known feed additives merely supplement the nutrients necessary for livestock or enhance the absorbability to promote the growth of livestock, and did not consider the improvement of meat quality. For example, in the conventional feed additive, the growth was fast and fat was also accumulated in the meat, but a thick and clear fat layer appeared and the portion called oily body increased. Even if the meat has accumulated fat, the oily meat does not match the taste, and if the meat appears more than necessary, for example, when the meat is frozen and thawed again, the oily meat layer and the muscle layer are separated. There is a drawback that it is easy to do. As a result of various studies conducted by the present inventors on conventional feed additives, it was found that the use of a specific unsaturated fatty acid calcium salt improves the meat quality, and an application was filed previously (Japanese Patent Application No. 3-353441). However, fatty acid calcium salts have a slightly low palatability, and tend to reduce the amount of other feeds until they become available, and even if they can be fed, the amount taken up in the body and accumulated between muscles. However, there was room for improvement.

The present invention has been made in view of the above points and provides a feed additive for livestock, which has a weight gain effect on livestock and improves yield, marbling, carcass grading grade and the like. With the goal.

[0006]

[Means for Solving the Problems] As a result of intensive studies to solve the above problems, the present inventors have improved palatability by using a specific protein-containing feed and a fatty acid calcium salt. The inventors have found that the amount taken into the body of livestock and the amount accumulated between muscles can be increased, and the meat quality of livestock can be improved, and the present invention has been completed.

That is, according to the present invention, at least one selected from a high protein content feed consisting of fish meal, cottonseed, beer lees, dried yeast, and heated soybeans and 2 parts of fatty acid calcium salts each.
The gist is a feed additive used in a weight ratio of 0 to 60:80 to 40.

Examples of the high protein content feed used in the present invention include feeds containing a high rate of indigestible protein in the stomach, preferably fish meal, cottonseed, beer meal, dried yeast and heated soybean. Yeast and heated soybean are more preferable, and at least one selected from these can be used.

Examples of the calcium salt of a fatty acid used in the present invention include a calcium salt of a fatty acid such as a saturated fatty acid or an unsaturated fatty acid having 6 to 22 carbon atoms. Examples of the saturated fatty acid include caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid, and the like, and unsaturated fatty acids include oleic acid, palmitoleic acid, and elaidic acid. , Linoleic acid, linolenic acid, ricinoleic acid, arachidonic acid,
Examples thereof include eicosapentaenoic acid, docosahexaenoic acid, erucic acid, etc., and at least one fatty acid selected from these saturated fatty acids and unsaturated fatty acids is used as the calcium salt.

As the fatty acid calcium salt, those produced by a conventional method can be used. For example, a method obtained by neutralizing calcium oxide, hydroxide or carbonate with the above fatty acid, and alkali metal fatty acid. It can be produced by a method obtained by metathesis of a salt with calcium oxide, hydroxide or carbonate.

The feed additive of the present invention comprises the above-mentioned high protein content feed and fatty acid calcium salt at 20 to 60:80, respectively.
It is preferable to contain it in a weight ratio of ˜40, and both the specified high protein content feed and the fatty acid calcium salt are indigestible in the stomach, pass through the stomach, and are sent to the digestive organs.
When the ratio of the both is in the above range, the protein and the fatty acid calcium salt are well balanced in the digestive organs, the amount of the protein effectively taken into the body of the livestock is increased, and the effects of gaining weight and improving meat quality are excellent. Regarding the weight ratio of the high protein content feed and the fatty acid calcium salt, the weight ratio of the high protein content feed of less than 20 and the fatty acid calcium salt of more than 80 is not preferable because the rate of incorporation of the fatty acid calcium salt into the body decreases. In addition, when the fatty acid calcium salt is less than 40 and the high protein content feed is more than 60, the amount of oil and fat is small, and the amount of protein is too large, so that the amount of ammonia generated is large, which may hinder the action of the bacterial flora in the stomach. There is.

In the present invention, livestock is fed with the above-mentioned feed additive to be bred, which is a normal fattening feed such as rice straw, oats hay, alfalfa, timothy hay, corn, barley, mylo, oats and beets. Concentrated feeds such as pulp, molasses, fruits, and citrus fruit by-products, feeds containing them, or feeds containing vitamins, inorganic compounds, other feed additives, etc., commercially available feeds or mixed feeds. It is possible to feed by blending or sprinkling it, or by mixing these and molding them into granules, pellets or the like. The feed amount of the feed additive of the present invention is 50 to 600 g / day for one livestock.
It is preferable to feed, and 100 to 500 g is more preferable. If the amount is less than 50 g, the effect of the present invention hardly appears, and even if the amount is 600 g or more, the effect corresponding to the increased amount is not observed and it is not economical.

Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited to these as long as the gist thereof is not exceeded.
