Abstract

PROBLEM TO BE SOLVED: To provide food capable of easily taking in nutritiously and pharmacologically valuable oleic acid by feeding oil and fat containing the oleic acid and/or one or two kinds of the derivatives to domestic animal kinds and poultry kinds and breeding them. SOLUTION: For instance, 4ml edible olive oil (fatty acid composition: 11.5% palmitic acid, 73.8% oleic acid, 8.8% linoleic acid and 2.8% stearic acid) is mixed in a well-known mixed feed (120g/bird per day) and is taken in every day for three weeks by the ovum collection fowl of 240 day-old and eggs laid by the ovum collection fowl are obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for producing an oleic acid-enriched animal food and an oleic acid-enriched animal food. The animal food is useful in the fields of foods, cosmetics, chemical products, pharmaceutical materials and the like.

[0002]

2. Description of the Related Art Oleic acid is a monounsaturated fatty acid having 18 carbon atoms and is known to have a function of lowering LDL cholesterol which promotes arteriosclerosis without lowering HDL cholesterol. In addition, oleic acid is less likely to be oxidized than polyunsaturated fatty acids, and has the advantage of suppressing the purification of lipid peroxide, which is inconvenient for living organisms. However, animal foods such as poultry eggs and meat with an increased oleic acid content have not been known so far.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an oleic acid-enriched animal food which can maintain nutritional and pharmacologically valuable oleic acid while retaining its original usefulness. Providing food, especially poultry eggs and meat.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies for the above purpose, and as a result, have been able to produce oleic acid-enriched animal foods by administering oleic acid-rich fats and oils to poultry. And completed the present invention.

The present invention has been completed on the basis of the above findings, and is characterized in that oleic acid-enriched animal foods are characterized in that poultry is bred by administering fats and oils containing oleic acid and / or a derivative thereof. And a oleic acid-enriched animal food.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, livestock is
Cattle, horses, pigs, sheep, goats and other livestock that are raised to produce animal foods, and poultry are animals that produce animal foods such as chickens, quails, ducks, and turkeys. Means poultry in general. In addition, animal foods are primarily edible products that are produced by livestock or poultry, such as poultry meat (including internal organs, etc.), livestock milk, poultry eggs, oils and fats, or obtained by slaughtering them. Means things. In order to serve this food,
This includes cases where it is used as a raw material for food. In addition, animal foods in which oleic acid is fortified in the processing step are not included in the present invention, but foods obtained by simply processing the above edible foods are within the scope of the present invention.

The oleic acid derivatives in the present invention include salts, esters, triacylglycerol, diacylglycerol, monoacylglycerol, glycerophospholipid, glyceroglycolipid, sphingolipid, and sphingolipid.

The oils and fats containing oleic acid and / or a derivative thereof used in the present invention are preferably those in which oleic acid accounts for at least 30%, preferably at least 50%, of the total fatty acids. Examples of such oils include olive oil, rapeseed oil (canola), safflower oil (an improved variety containing high oleic acid), and olive oil is particularly preferred.

The method of administration is generally a method in which the above fats and oils are mixed with a known feed and ingested, but subcutaneous inoculation is also possible.

[0010] The feed components other than the above fats and oils may be the same as feeds known as feed for each animal to be bred, such as protein,
It contains energy sources, calcium sources, phosphorus sources, vitamins, minerals and the like. Protein sources include fish meal, soybean meal, rapeseed meal, feather-mill, meat-bon mill, etc., and methionine L to supplement amino acid imbalance.
-Amino acids such as tryptophan, L-lysine and L-threonine may be added. As energy sources, corn mylo, carbohydrates such as flour, feed fats and oils,
There are fats such as soybean oil and powdered fat. Examples of the calcium source include calcium carbonate. In addition, needless to say, it is necessary to contain a phosphorus source, vitamins, minerals and the like in the same manner as in the known feed. For example, in the case of poultry, the content may be about 12 to 25% of crude protein, about 3 to 10% of crude fat, about 1.0 to 4.5% of calcium, and about 2700 to 3300 Kcal / kg of metabolizable energy (ME).

The feed may be further mixed with molasses, alfalfa meal, various flavors, acidulants, etc., or added with a soap smell masking agent, yeast, lactic acid bacteria, etc., in order to improve palatability. Further, antioxidants and antibacterial agents for preventing oxidization and decay and improving preservability, and vitamins and minerals for enhancing nutritional value may be added. The feed composition may be processed into pellets, cubes, wafers, flakes and the like.

The mixing ratio of the above fats and oils is in the range of 0.5 to 10% by weight as crude fat of the total feed. This mixing ratio may be changed depending on the amount of crude fat in the basic feed, but is preferably in the range of 0.5 to 5% by weight.

The oil or fat containing oleic acid and / or its derivative may be added together with or separately from the feed components in the feed mixing process and uniformly mixed, and an emulsifier or a vitamin may be used. At this time, it is desirable to adjust the crude fat amount and metabolic energy of the whole feed to desirable values according to the target animal. The feeding method can be performed in the same manner as in the prior art.

In the subcutaneous inoculation, it is desirable to inoculate 1 ml to 50 ml, preferably 2 ml to 15 ml, from the viewpoint of the health condition, egg production rate and oleic acid content of the poultry. Further, an emulsifier, a vitamin and the like may be added to the inoculated oil and fat.

When the animal food thus obtained is subjected to methyl esterification by a conventional method, for example, a methanol-hydrochloric acid method or the like, the fatty acid composition of any fatty acid derivative ester-bonded in the food can be analyzed by GLC. In addition, food is extracted using an organic solvent or the like, and silica gel T
After fractionating lipids by LC, the constituent fatty acids of each lipid can be analyzed in the same manner.

【Example】

Example 1 Five Isa Brown laying hens (240 days old) (test group)
4 ml of edible olive oil (fatty acid composition: palmitic acid 1
1.5%, oleic acid 73.8%, linoleic acid 8.8
% And 2.8% of stearic acid) were mixed with a mixed feed (120 g per bird per day) and ingested daily for 3 weeks. Thereafter, the fatty acid composition of the yolk of the eggs laid by the laying hens was compared with that of a control group of 5 birds to which no olive oil was administered. Table 1 shows the results. The fatty acid composition was measured by gas chromatography after methyl esterification by a conventional method.
