2. Description of the Related Art In recent years, from the boom of health foods, many attempts have been made especially to enhance the added value of foods by strengthening and blending specific nutritional components in the foods to differentiate them from conventional products. Against this background, in the field of livestock, especially in the field of poultry, many products have been developed in which the essential fatty acids such as α-linolenic acid and docosahexaenoic acid have been reinforced in the lipids in chicken eggs. Attempts have been made to strengthen the α-linolenic acid and the like.

The inventors of the present invention are characterized by feeding a feed for laying hens containing a long-chain unsaturated fatty acid calcium salt having 18 or more carbon atoms as an active ingredient, and feeding the feed to laying hens, thereby lowering the egg rupture rate, An application for an invention relating to a method for breeding laying chickens having an effect of extending the spawning period and the like was previously filed (WO93 / 19618).

Conventionally, in order to achieve the purpose of strengthening these essential fatty acids, feeds to be fed to laying chickens, meat chickens, etc.,
It has been practiced to add seeds of plants having a high content of α-linolenic acid, vegetable oil extracted and purified from the seeds, fish meal containing docosahexaenoic acid, and the like at a fixed ratio to feed the seeds. For example, a method of preparing and feeding a feed containing an extruder-processed full-fat soybean (JP-A-4-2717).
No. 54) and the like are disclosed, and it is known that the feeding of a feed containing a large amount of these specific essential fatty acids can markedly increase the specific essential fatty acids in meat.

[0005]

However, in the conventional method, there is a limit to the amount of specific essential fatty acid such as α-linolenic acid to be fortified as shown in the test examples described later, and humans ingest these foods. It is difficult to say that the effect obtained by the above is sufficient, and that the fluctuation of the amount of specific essential fatty acids such as α-linolenic acid transferred to meat lipids is large. There was a big problem above. Further, in the method of adding plant seeds or vegetable oil to the feed, it was also very difficult to uniformly mix the feed with the feed. Further, since highly unsaturated essential fatty acids such as α-linolenic acid easily undergo oxidative deterioration in the air, it is not possible to mix vegetable oils and fats with a high content of these fatty acids in the feed as they are. There is a problem that it is not preferable from the viewpoint of poultry physiology, in addition to its palatability as a feed composition.

As a result of intensive studies to solve the above-mentioned problems in the prior art, the present inventors have recently demanded the active intake of lipid nutrition in consideration of the current state of human lipid nutrition. Efficient incorporation of essential fatty acids such as α-linolenic acid into lipids in edible poultry meat was produced using linseed oil extracted and purified from linseed seeds highly containing this essential fatty acid. It can be easily achieved by feeding fatty acid calcium salt, and even in the case of poultry feeding, the breeding method for incorporating essential fatty acids such as α-linolenic acid into the product is completely different between spawning and meat. I found that. That is, the present inventors
The fatty acid calcium salt of linseed oil containing a large amount of α-linolenic acid is an extremely small amount, and even with a short feeding period, α-linolene is more efficiently compared to the conventional method of blending plant seeds or vegetable oil. The present invention has been completed based on the finding that it is possible to incorporate an acid, the amount of the acid to be contained in poultry meat can be easily adjusted, and the acid can be simply and highly contained.

The object of the present invention is to eliminate the above-mentioned problems found in the prior art and to allow lipids in poultry meat to easily and highly contain essential fatty acids such as α-linolenic acid. Α in dietary and in poultry meat lipids of edible poultry
-An object of the present invention is to provide an α-linolenic acid enhancer in a poultry meat lipid, which can easily and highly enhance linolenic acid.

Another object of the present invention is to control the lipid content in poultry meat.
-To provide a method for feeding edible poultry capable of easily and highly containing essential fatty acids such as linolenic acid.

[0009]

The first invention of the present invention for solving the above-mentioned problems is characterized in that it contains at least 0.1% (by weight) of a fatty acid calcium salt of linseed oil, which is an edible poultry feed. Further, it is an α-linolenic acid enhancer in poultry meat lipid of edible poultry, which contains the composition as an active ingredient, and is produced by heating fatty acid calcium salt of linseed oil of 80% (by weight) or more, molasses and sugar. At least 0.13% (by weight) of a browning substance, a browning substance produced by heating sugar and amino acid, or a mixture of at least two components in an arbitrary ratio of 20% (by weight) or less. Furthermore, it is also a desirable embodiment that the composition is the active ingredient.

A second aspect of the present invention for solving the above-mentioned problems is to provide an edible poultry feed containing at least 0.1% (by weight) of a fatty acid calcium salt of linseed oil to the edible poultry before shipment for at least 2 days. A method for feeding edible poultry characterized by feeding, wherein 80% (by weight) or more of fatty acid calcium salt of linseed oil, and molasses, browning substance produced by heating sugar, browning substance produced by heating sugar and amino acid , Or a mixture of at least 0.1% (by weight) of a mixture of 20% (by weight) or less of a mixture of any of these at least 0.13% (by weight), and edible poultry before shipment for at least 2 days. In addition, it is a preferable aspect to feed these edible poultry feeds to edible poultry within 2 weeks before shipment for 5 to 7 days.

Next, the present invention will be described in detail. The fatty acid calcium salt of linseed oil used in the present invention is a known method,
For example, it is produced by a method such as the double decomposition method (edited by Toshiyuki Yoshida et al., "Properties and Applications of Metal Soap", page 15, Koshobo, 1988). In this manufacturing process, a predetermined amount of browning substance may be mixed in advance to cause the fatty acid calcium salt formation reaction.

The molasses used in the present invention is a commercially available product, and a browning substance produced by heating sugar, a browning substance produced by heating sugar and amino acid, or a mixture thereof in any ratio can be used.

The edible poultry feed, which is the first invention of the present invention, is manufactured as follows. A predetermined amount of the browning substance is mixed with a predetermined amount of the linseed oil fatty acid calcium salt powder, and is uniformly mixed using a mixer or the like. As another production method, a predetermined amount of browning substance may be added in the step of producing the fatty acid calcium salt of linseed oil as described above. In any method, the blending amount of the browning substance is 20% or less, preferably 0.5 to 10%. At least 0.1 fatty acid calcium salt of linseed oil
% Or a mixture of the fatty acid calcium salt of linseed oil and the browning substance in a ratio of at least 0.13%, for feed for edible poultry (for example, commercially available feed for broilers, etc.)
Is mixed with the above ingredients and mixed to produce the feed of the present invention.

If the proportion of the fatty acid calcium salt of linseed oil or the mixture of the browning substances in the feed exceeds 10% in terms of the fatty acid calcium salt of linseed oil, it may have an unfavorable effect on the physiology of edible poultry. So give
It should be avoided. Although the edible poultry feed of the present invention is produced as described above, other feed ingredients such as alfalfa meal can be simultaneously added if necessary.
Further, in the present invention, it is possible to prepare an α-linolenic acid enhancer in poultry meat lipids of edible poultry by finishing the above-mentioned composition as an active ingredient into a product in an appropriate form by a conventional method. is there.

The method for feeding edible poultry according to the second aspect of the present invention is the above-mentioned feed, that is, edible poultry feed containing at least 0.1% of linseed oil fatty acid calcium salt, or linseed oil fatty acid calcium. 80% or more of salt, molasses, browning substance produced by heating sugar, browning substance produced by heating sugar and amino acid, or a mixture of at least two components of 20% or less of a mixture of these at least two components at least 0 An edible poultry feed containing .13% is fed by a conventional method for at least 2 days before shipment of the edible poultry under feeding, preferably 5 to 7 days within 2 weeks before shipment. The feeding period can be arbitrarily adjusted by the fatty acid calcium salt content of the linseed oil in the feed, the production cost, the set value of essential fatty acids such as α-linolenic acid contained in the lipid of poultry meat, and the like. Needless to say, in the method for feeding edible poultry according to the present invention, it is also possible to appropriately use the above-mentioned composition in the form of the α-linolenic acid enhancer.

Next, the present invention will be described in detail by showing test examples. Test Example 1 In this test, the effect of feeding a dietary feed for edible poultry containing a fatty acid calcium salt of linseed oil on the fatty acid composition of lipids in muscle of edible poultry was determined for edible poultry containing refined linseed oil and linseed seeds. This was done for comparison with the case where the feed was fed.

Then, these were divided into 4 groups of 30 birds each, and feed A was fed to group A, feed 2 to group B, feed 3 to group C, and feed 4 to group D for 2 weeks.

The animals were bred for a total of 8 weeks, and 5 birds were indiscriminately selected from each group, exsanguinated to death, dissected, and pectoral muscles (anatomically referred to as superficial pectoralis muscles; hereinafter the same) were collected. The fatty acid composition of the lipid contained in was measured by the following method. Lipids are extracted from the crushed muscle with a mixed solution of chloroform-methanol (2: 1), and the conventional method (edited by Japan Oil Chemistry Association, “Standard Oil and Fat Analysis Test Method”, 2.4.20-17, incorporated corporation) Methyl esterified by Japan Oil Chemistry Association, 1986),
The fatty acid composition of the lipids was quantified and tested by gas chromatography.

(3) Test Results The results of this test are shown in Table 1. As is clear from Table 1, the α-linolenic acid content in lipids in the pectoral muscle was the highest value of 7.2% in the group fed the linseed oil fatty acid calcium salt-added feed (Feed 1). And 4.6 in the feed group containing refined linseed oil (feed 2)
%, 4.0% in the linseed seed-added feed (feed 3) feeding group
It was found that the fatty acid calcium salt of linseed oil significantly increased α-linolenic acid in the pectoral muscle as compared to linseed oil or linseed seeds. Although not shown in the table, the amount of fatty acid calcium salt of linseed oil in the feed was 0.1.
%, It was confirmed that α-linolenic acid in the pectoral muscle was increased as compared with the control diet-fed group. The test was conducted by changing the compounding ratio of the fatty acid calcium salt of linseed oil, the refined linseed oil and the linseed seeds, but almost the same results were obtained.
