Abstract

PROBLEM TO BE SOLVED: To obtain a nutrition composition for horse free from giving a load to a horse, suitable for the improvement of nutrition conditions of horses, especially of racing horses and mainly containing essential amino acids. SOLUTION: This nutrition composition for horse mainly contains essential amino acids consisting of valine, isoleucine, leucine, tryptophan, phenylalanine, methionine, lysine, threonine and histidine. The nutrition composition especially having a ratio of essential amino acids/non-essential amino acids of >=0.5 is effective. Giving the nutrition composition to a horse has the following effects. For a racing horse on active duty, fodder consumption does not decrease after racing, accordingly, the horse can recover quickly from fatigue, and the improvement of performance is expected. For a horse having trouble such as injury, curing or recovery is accelerated. For a horse in conception, nutritional conditions are improved, and accordingly an abortion rate is decreased. Further, the growth of the foal is accelerated since the nutritional value of postpartum horse milk is improved. For a growing foal, the growth is accelerated than in the case of a conventional food.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a nutritional composition for horses containing, as a main component, an essential amino acid consisting of valine, isoleucine, leucine, methionine, threonine, lysine, tryptophan, phenylalanine and histidine. In particular, it relates to a nutritional composition for improving the nutritional status of racehorses.

2. Description of the Related Art For example, Japanese racehorses are temporarily malnourished during severe training. The reason for this is oats, bran, which are used as the staple food of racehorses.
The protein content of bokso is 3-15% by weight
Because it is low. As inferred from the standard feed conversion value, the protein ingested by the racehorse is deficient as a whole or mainly in essential amino acids. It is considered that sufficient intake of high-quality protein can withstand rigorous training, increase muscle strength and increase calcium absorption efficiency, and eventually lead to reduction of injury and failure rate. Taking into account the energy consumption at the time, the energy intake is being improved by increasing the protein intake.

[0003] In order to provide protein, a high-protein compounded feed has hitherto been used, but the protein content of this compounded feed, ie, the essential amino acid content in the total amino acids, is at most about 40%. The remaining about 60% are non-essential amino acids. If the non-essential amino acids are high like this,
If you try to get the required amount of essential amino acids, you have to get an excessive amount of non-essential amino acids, which is likely to overload your internal organs due to metabolism, and such a burden is not preferable for the horse body. .

[0004]

[Problems to be Solved by the Invention] In order to keep the horses of horses, especially racehorses, in good condition, it is important to feed them with sufficient nutrition. It is to give it efficiently. That is, an object of the present invention is to develop a horse nutrition composition containing an essential amino acid as a main component, which is suitable for improving the nutritional state of horses, especially racehorses, without giving a burden to the horse body.

[0005]

[Means for Solving the Problems] As a result of analyzing the standard feed conversion table for horses and examining the amino acid balance, it was found that the amino acids necessary for horses are deficient in valine, isoleucine, leucine, tryptophan, phenylalanine, It has been found to be an essential amino acid consisting of methionine, lysine, threonine and histidine.

The amino acid mixture obtained by simply hydrolyzing or enzymatically decomposing animal or plant proteins has a low proportion of essential amino acids, and is therefore applicable to the nutritional composition containing the essential amino acids as the main component of the present invention. Is difficult to do.
Then, the crystalline amino acid was used, the amino acid compounding amount was examined, and further, the ratio of the essential amino acid and the non-essential amino acid among the crystalline amino acids was changed, and the most effective horse nutrition composition was examined.

Based on the results of these studies, the present inventors have invented a nutritional composition suitable for horses. That is, the present invention is a nutritional composition for horses containing, as a main component, essential amino acids consisting of valine, isoleucine, leucine, tryptophan, phenylalanine, methionine, lysine, threonine and histidine.
