2. Description of the Related Art In order to maintain livestock health and promote growth,
Various feed additives have been used. For example, commonly used feed additives are fats and oils, vitamins, minerals, amino acids, etc., which supplement the nutrients lacking in the feed,
Alternatively, it is used to improve the digestive absorption rate and the fattening effect. Ruminants among livestock are number one.
The feed is broken down by microorganisms in the stomach and digested in the abomasum, but does not inhibit the growth of microorganisms in the abomasum.
Studies have also been conducted on feed additives having a function of being digested well in the digestive tract after the stomach.

[0003] As such feed additives, feed additives for promoting animal growth by fatty acid calcium salts or feeds using the same (JP-A-58-47442) are known, and the growth of livestock such as ruminants is known. Has been reported to be effective in maintaining health.

[0004]

[Problems to be Solved by the Invention] Compared to other countries, there is something unique in meat taste in Japan, and so-called marbled meat in which fat is crossed like a spot in muscle is preferred.
Such meat has tenderness as well as tenderness. Conventionally known feed additives merely supplement the nutrients required for livestock or enhance their absorption to promote livestock growth, and do not consider meat quality improvement. For example, in the case of a conventional feed additive, the growth is fast and fat is accumulated in the meat, but a thick and clear fat layer appears, and a portion called oil body increases. Even if the meat has accumulated fat, the oil does not suit the taste, and if it appears more than necessary, for example, it is frozen once and then thawed again, so that the oil layer and muscle layer separate. There is a drawback that it becomes easier. The present inventors have conducted various studies on conventional feed additives. As a result, they have found that the use of a specific unsaturated fatty acid calcium salt improves meat quality. However, fatty acid calcium salts have a slightly lower palatability and tend to reduce the amount of other feeds taken until they become available, and even if they can be fed, they are taken up by the body and accumulated in muscle. However, there is a problem that the number is insufficient, and there is room for further improvement.

The present invention in view of the above problems, has been made, there is weight gain effect on edible cattle, to provide yield, marbling, extender improved method of cooking beef, such as carcass grading grade
For the purpose.

The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, have been determined to feed a specific protein-containing feed and a fatty acid calcium salt at 100 to 500 g per animal per day.
With this , it was possible to improve palatability, further increase the amount taken into the body of edible cattle , and increase the amount accumulated between muscles, and found a method for improving the meat quality of edible cows , leading to the present invention. .

[0007] That is, the present invention relates to a method for preparing at least one kind selected from a high protein-containing feed consisting of fish meal, cottonseed, beer meal, dried yeast and heated soybean, and a fatty acid calcium salt,
0-60: 80-40 weight ratio per cow
100-500g daily edible beef
The gist is a constitution improvement method .

The high protein-containing feed used in the present invention includes a feed containing a high percentage of indigestible protein in the stomach, preferably fish meal, cottonseed, beer lees, dried yeast and heated soybean. Yeast and heated soybean are more preferred, and at least one selected from these can be used.

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

As the above-mentioned 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 and the above fatty acid, alkali metal of 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 high protein-containing feed and the fatty acid calcium salt in an amount of 20 to 60:80, respectively.
It is preferable to contain at a weight ratio of ４０40, and the specified high protein-containing feed and the fatty acid calcium salt are both indigestible in the stomach and pass through the stomach, and are sent to the digestive tract,
When the ratio of the two is in the above range, the protein and the fatty acid calcium salt are well-balanced in the digestive tract, the amount effectively taken into the body of edible cattle is increased, and the effect of increasing body weight and improving meat quality is favorably exhibited. The weight ratio between the high protein-containing feed and the fatty acid calcium salt is less than 20 when the high protein-containing feed is less than 20 and the fatty acid calcium salt is more than 80 because the rate of fatty acid calcium salt incorporation into the body decreases. In addition, if the fatty acid calcium salt is less than 40 and the high protein-containing feed exceeds 60, the amount of fat and oil is small, and the amount of protein is too large, so that the amount of generated ammonia increases, which may inhibit the function of the bacterial flora in the stomach. There is.

In the present invention, edible cattle are fed and bred with the above-mentioned feed additive by using a conventional fattening feed such as rice straw,
Oat hay, alfalfa, hay such as timothy, corn, barley, mylo, oats, beet pulp, molasses, fruits, concentrated feed such as by-products of citrus fruits, feeds containing these, or vitamins, inorganic compounds, It can be fed or sprinkled into feeds containing other feed additives, commercially available feeds or mixed feeds, or can be fed in the form of granules, pellets or the like obtained by mixing these. . Feed additives are supplied at a rate of 100-500 g / day per cow.
Can be given . If the amount of salary is less than 100 g, the effect of the present invention is less likely to appear, and even if the amount is 500 g or more,
It is not economical because there is no increase in the effect corresponding to the increased amount.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited thereto without departing from the gist thereof.
