JPH03219838A - Feed for reducing amount of accumulated body fat - Google Patents

Abstract

PURPOSE:To provide a feed having action of improving fat metabolism of livestock and reducing the amount of accumulated body fats by adding respective specific amounts of valine, leucine and isoleucine as amino acid ingredients to a feed for the livestock and enriching the feed. CONSTITUTION:Valine, leucine and isoleucine in respective amounts within the range of 0.01-3wt.% as amino acid ingredients are added to enrich a feed composed of fish meal, soybean cake, corn, wheat flour, soybean oil, vitamins, minerals, etc., for livestock. The resultant feed can be then supplied to the livestock to reduce the amount of accumulated body fats without effecting living body weight of the livestock. Thereby, a livestock product fit for the recent trend requiring the livestock product with a low body fat content for reasons of human health can be provided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a feed that improves fat metabolism and reduces body fat accumulation in livestock.

[Conventional technology]

In recent years, livestock animals have been increasing their energy intake for the purpose of promoting growth, and there is a tendency for the amount of accumulated body fat to increase.

However, recently, much attention has been paid to the effects of diet on health, and livestock products with low body fat are required, and methods to produce livestock products with low body fat and the development of feeds are widely requested. was.

[Problem to be solved by the invention]

However, although there is a wide demand for such feeds that produce livestock products with low body fat, no effective feed has been developed.

[Means to solve the problem]

By the way, it has long been known that ingesting a large amount of protein in your diet reduces the amount of body fat accumulated. In vitro studies have shown that this is because amino acids, which are constituents of proteins, inhibit fat synthesis in adipocytes.
It has been proven from experiments.

In this in vitro experiment, the substances with the greatest degree of inhibition of fat synthesis were alanine, valine, cystine,
The order of these amino acids is methionine, leucine, isoleucine, lysine, etc., but with the exception of lysine and methionine, there have been almost no tests on the ability of these amino acids to inhibit fat synthesis by administering them to animals or humans. .

Furthermore, it has been known that feeding livestock with feed containing feather meal as a feed ingredient reduces the amount of body fat accumulated in the livestock, but the second cause has not been clarified.

In order to develop a feed that reduces body fat accumulation, the present inventors investigated the effects of feeding the various amino acids mentioned above on body fat accumulation to broilers, and
We also researched the causes of Mir's body fat loss. As a result, it was discovered that a feed enriched with three types of amino acids: valine, leucine, and isoleucine suppresses the amount of body fat accumulated, thereby completing the present invention.

That is, the feed for reducing body fat accumulation of the present invention is characterized by being enriched with valine, leucine, and isoleucine as amino acid components in the range of 0.01 to 3.00% by weight, respectively.

In the feed of the present invention, other ingredients may be the same as in conventional feeds, as long as each of the three types of amino acids mentioned above is enriched within a specified range.

If the amount of each of the above amino acids added is less than 0.01% by weight, there will be no effect of suppressing body fat accumulation;
If it exceeds 0.00% by weight, the amino acid balance will be too disturbed, resulting in unfavorable results in terms of weight gain.

The three amino acids valine, leucine, and isoleucine may be in the form of single crystals or amorphous powders, or may be a mixture.

Addition of the three types of amino acids to feed may be carried out in the same manner as conventional production methods. Also, feeding to livestock may be the same as before.

Other feed ingredients may be known feeds for livestock, such as protein, energy source, calcium source, phosphorus source, vitamins, etc.
It contains minerals, etc., and is formulated to meet NCR requirements. Examples of protein include fish meal, soybean meal, rapeseed meal, feather meal, meat pone meal, etc. Amino acids such as DL-methionine, L-tryptophan, and L-threonine may be added to compensate for amino acid imbalance. . Energy sources include hydrocarbons such as corn, milo, and wheat flour, feed oils, soybean oil, powdered oils, and the like. In addition, it is necessary to contain phosphorus sources, vitamins, minerals, etc. in the same way as known feeds. The content of the ingredients is
Crude protein 12-25%, crude fat 3-10%, calcium 0.8-2.0%, ME 2700-3300
It may be about Kcal/kg.

[Effect] By enriching feed ingredients with the amounts of three types of amino acids: valine, leucine, and isoleucine, the amount of body fat accumulated in livestock fed with the feed ingredients is reduced.

[Example] Example 1 Feed in which 0.4% by weight of alanine, cystine, valine, leucine, and isoleucine were added alone to a commercially available broiler feed (Proace G, Itochu Feed Product), and each of the above five amino acids was added. Feed containing 0.4% by weight of valine, leucine, and isoleucine each.
Eight types of feed were prepared, including feed with additives and feed without additives.

Using 80 34-day-old broiler chickens, there were 8 test plots of 10 chickens in each group, and the feed was fed to them for 25 days until they were 59 days old.
A daily feeding test was conducted.

After the test was completed, abdominal fat amount was measured.

The test results are shown in the table below.

From the above results, it is clear that feed enriched with valine, leucine, and isoleucine has the function of suppressing body fat accumulation.

In addition, even if these three types of amino acids were used alone or in combination, there was no significant difference in live weight, and there was no effect on growth.

Example 2 Commercially available broiler feed (Broiler G, Itochu Feed Product) was supplemented with 0 valine, leucine, and isoleucine.
．． Two types of feed were prepared: one with 5% by weight added and one with no additives.

Using 100 42-day-old broiler chickens, 50 per group
Two test plots were prepared with 25 birds (25 birds x 2 repetitions), and a feeding test was conducted for 14 days until the age of 56 days by feeding the above feed.

After the test was completed, abdominal fat amount was measured.

The test results are shown in the table below.

From the above results, it is clear that feed enriched with valine, leucine, and isoleucine has the function of suppressing body fat accumulation.

In addition, even if these three types of amino acids were used alone or in combination, there was no significant difference in live weight, and there was no effect on growth.

Example 3 Feather meal, blood meal and corn gluten meal rich in valine, leucine and isoleucine were prepared at 10% each.
Feed containing weight percent and additive-free feed [Effects of the Invention] By configuring the present invention as described above, it is possible to reduce the amount of accumulated body fat without affecting live weight.
