JPH0880164A - Production of egg of edible fowls and feed for ovum collection - Google Patents

Abstract

PURPOSE: To obtain a feed for egg collection, designed to contain a large amount of a specific ingredient in an egg without producing an odorous ingredient inhibiting the taste, having high palatability for fowls and good in egg production efficiency. CONSTITUTION: This method for producing eggs of edible fowls is to make females of fowls such as a chicken, a quail, a duck or a crossbreed of wild and domestic ducks ingest a feed for the ovum collection prepared by adding a linseed to a feed consisting essentially of a vegetable substance and lay eggs containing eicosapentaenoic acid or docosahexaenoic acid or a mixture thereof by the females.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing edible bird eggs and a bait for egg collection.

[0002]

2. Description of the Related Art Generally, edible avian eggs include chicken eggs, quail eggs, duck eggs, duck eggs and the like, and a predetermined component is provided in order to efficiently breed female parent birds from which such edible avian eggs are collected. Blended feed is used.

[0003] For example, the formulation of the feed used for poultry (for adult chicken) is 0 to 30% of corn (weight%, the same hereinafter), 20 to 50% of wheat, 7.5 to 12% of rice bran,
Bran 14.5 to 19.5%, soybean meal 6 to 10%, fish cake 8 to 10%, lime carbonate 3 to 5%, salt 0.4 to 0.
6% is typical.

Among the above-mentioned components, fish cake (fish meal, fish oil) contains polyunsaturated fatty acids which constitute the fat content of fish, and among them, human blood such as eicosapentaenoic acid and docosahexaenoic acid are contained. It also contains compounds effective in preventing coagulation and preventing arteriosclerosis.

[0005]

However, polyunsaturated fatty acids such as eicosapentaenoic acid (hereinafter abbreviated as EPA) or docosahexaenoic acid (hereinafter abbreviated as DHA) are efficiently added to the eggs of birds from the feed. It is often difficult to transfer to the living body (egg). Because
This is because, for example, a feed containing fish residue and containing a large amount of polyunsaturated fatty acids has a problem that the palatability of birds is lowered, that is, the feeding efficiency is poor and the egg laying rate is also lowered. In this case, the efficient transfer of EPA into the egg is DH
It is more difficult than the case A.

[0006] When fish oil was added to the feed for birds and the taste of eggs laid was examined, not only polyunsaturated fatty acids but also fish oil odor was transferred into the eggs. There is also the problem of not producing good edible eggs.

As a compounding ingredient for foodstuffs other than the above fish meal, there are linoleic acid and α-linolenic acid which can induce EPA and DHA in the living body, and plants containing perilla, sesame, etc. include these. , Or vegetable oils squeezed from them are known.

However, none of these match the palatability of birds, and vegetable oil is rapidly oxidized by oxygen in the air.
The amount of metabolic synthesis of HA was extremely small.

Therefore, an object of the present invention is to solve the above-mentioned problems, and to provide a method for producing edible bird eggs, in which no odorous component that inhibits taste is produced in the eggs, and further, in the eggs, eicosapentaenoic acid, This is to make a large amount of docosahexaenoic acid contained. In addition, the egg-collecting bait used at that time is to have a high palatability for birds and a high egg-laying efficiency.

[0010]

Means for Solving the Problems In order to solve the above problems, in the present invention, production of edible avian eggs in which a female of birds ingests flaxseed and lays eggs containing eicosapentaenoic acid or docosahexaenoic acid or both It was a method.

[0011] In addition, a feed for breeding birds, which contains plant matter as a main component, is supplemented with flaxseed to provide a feed for egg collection.

[0012]

In the method for producing edible bird eggs according to the present invention, the flaxseed, which contains a large amount of polyunsaturated fatty acids such as linolenic acid, linoleic acid, and oleic acid, and which has a small odorous component, is introduced into the birds. , A useful component contained in the flaxseed, or eicosapentaenoic acid, which is a metabolic synthetic component in the avian body starting from this component, or docosahexaenoic acid or both of them, and has less odorous component And produce good quality eggs.

Further, since flaxseed has a small odorous component as described above, the compounded feed containing flaxseed has a high palatability for birds and serves as an egg-laying feed which can enhance the spawning efficiency.

[0014]

EXAMPLES The birds in the present invention are not particularly limited as long as they can collect edible eggs, and examples thereof include chickens, quails, ducks, and ducks.

Flaxseed (English name: Flax used in the present invention
seed and Linseed) are seeds of flax (Linum usitatissimum), which is an annual plant of the family Flaxaceae. The surface of flaxseed is brown, glossy and flat oval, 4 to 6 mm in length, has almost no odor, and has a mild oily taste and a slimy taste.

As flaxseed, dried seeds having good storage stability can be used, but the loss on drying is usually about 6.8%. And the component of mature flaxseed has an ash content of 3.7.
% (Acid-insoluble ash 0.2%), fatty oil 25.0 to 45.
0% and such fatty oils consist of glycerides of linolenic acid, linoleic acid and oleic acid.

The bird feed containing plant matter as a main component used in the present invention is preferably a feed containing a plant having a high palatability for birds from which the above-mentioned food eggs can be collected as a main component. It does not limit the types of plants that become.

Blending example of feed ingredients other than flaxseed (for adult chicken)
As mentioned above, corn 0-30%
(Wt%, the same below), wheat 20-50%, rice bran 7.5-12%, bran 14.5-19.5%, soybean meal 6-10%, fish cake 8-10%, lime carbonate 3 ~ 5%,
It is possible to employ 0.4 to 0.6% of salt.

[Example 1] As a feed for quail, 5% by weight of a mixture of yellow corn, soybean meal, milo, white fish meal, fish soluble, bran, alfalfa meal, animal fats, and salt was added.
Flaxseed (wt%) was added and mixed to produce an egg-collecting feed.

The obtained egg-collecting bait was used as a quail adult female 15
Feathers were fed continuously at an average rate of 18 g / feather / day for 14 consecutive days, and the egg production rate after 14 days, α-linolenic acid in eggs, EP
The contents of A and DHA (proportion of each component in the total polyunsaturated fatty acid by gas chromatography, shown in% in Table 1) were determined, and the results are shown in Table 1.

[0021]

[Table 1]

[Comparative Example 1] In the egg-collecting feed used in Example 1, 5% by weight of perilla oil and 5% of sesame were used instead of flaxseed.
A bait for egg collection was prepared in exactly the same manner as in Example 1 except that the weight% was added.

The resulting egg-collecting feed was fed to 15 adult quail females under exactly the same conditions as in Example 1, and the egg-laying rate after 14 days, α-linolenic acid in the eggs, EPA, and DHA were determined. The content was determined, and the results are also shown in Table 1.

Comparative Example 2 An egg-collecting feed used in Example 1 was prepared in exactly the same manner as in Example 1 except that flaxseed was not added.

The resulting egg-collecting feed was fed to 15 adult quail females under exactly the same conditions as in Example 1, and the egg-laying rate after 14 days, α-linolenic acid in the eggs, EPA and DHA, respectively. The content was determined, and the results are also shown in Table 1.

The production method of Comparative Example 1 was inferior in feeding efficiency, and as is clear from the results in Table 1, the egg laying rate was 69.
It was as low as 7%.

On the other hand, according to the production method of Example 1 in which the diet containing flaxseed was fed, the α-linolenic acid in the egg, E
The content of each of PA and DHA was sufficient, and the egg laying rate was as high as in Comparative Example 2 (blank).

Example 2 As a feed for chickens, 5% by weight of flaxseed was added to 95% by weight of a mixture of yellow corn, soybean meal, fish meal (brown fish meal), defatted rice bran, rouxan meal, salt and calcium carbonate. The mixture was mixed to produce a feed for egg collection.

The resulting egg-collecting bait was used at a rate of 100 g / bird / day for 12 adult female chickens (white leghorns).
Feeding continuously for 4 days, spawning rate after 14 days, α-linolenic acid per egg (average 60 g / piece), EPA, DH
Content of A, cholesterol, lecithin (m
g) was determined and the results are shown in Table 2.

[0030]

[Table 2]

[Comparative Example 3] An egg-collecting feed used in Example 2 was prepared in exactly the same manner as in Example 2 except that flaxseed was not added.

The resulting egg-collecting feed was fed to 12 adult female chickens (white leghorn species) under exactly the same conditions as in Example 2, and the egg-laying rate after 14 days, α-linolenic acid in the eggs,
The respective contents of EPA, DHA, cholesterol and lecithin were determined, and the results are also shown in Table 2.

As is clear from the results shown in Table 2, the chicken egg of Comparative Example 3 produced by feeding the diet without flaxseed did not produce EPA at all in the egg.

On the other hand, according to the production method of Example 2 in which the diet containing flaxseed was fed, α-linolenic acid in the egg, E
The results showed that the contents of PA and DHA were sufficient, the cholesterol level was low, and the egg production rate was high.

[Comparative Examples 4 to 7] The egg-collecting feed used in Example 2 was prepared in exactly the same manner as in Example 2 except that flaxseed was not added (Comparative Example 4). .

In the egg-collecting feed used in Example 2, flaxseed was not added, and fish oil (sardine oil) was added in an amount of 3% by weight, 4% by weight or 5% by weight (Comparative Examples 5, 6, and 7). Except for the above, an egg-collecting feed was prepared in exactly the same manner as in Example 2.

The above-obtained egg-collecting baits were fed to 12 adult female chickens (white leghorns) under the same conditions as in Example 2, and 14 days later, EPA or DHA.
Content (mg / piece) was determined, and the results are shown in Table 3.

[0038]

[Table 3]

As is clear from the results shown in Table 3, when fish oil was added to the feed, eggs containing no EPA were obtained.

A sensory test was conducted on the chicken eggs obtained in the above-mentioned Examples and the chicken eggs obtained in Comparative Example 7 using 7 adults as panelists. In addition, in the sensory test, the taste was examined while stirring two raw chicken eggs,
The rate (%) of the evaluation (points) was examined for three-level evaluations of good taste, normal, and bad taste. In addition, in the odor test, the evaluation (point) rate (%) regarding the presence or absence of fish oil odor was examined, and these results are shown in Table 4.

[0041]

[Table 4]

As is clear from the results shown in Table 4, the eggs obtained by using the feed of Comparative Example 7 containing 5% of fish oil were:
The smell of fish oil was felt by almost all panelists, but Example 2
The chicken eggs obtained by using the above food had no fish oil odor and excellent taste was obtained.

[0043]

[Effect] As described above, since the present invention is a method for producing edible bird eggs, in which flaxseed is ingested by avian females, no odorous components that inhibit taste are contained in the eggs,
Moreover, there is an advantage that an edible bird egg containing a large amount of eicosapentaenoic acid and docosahexaenoic acid useful for the human body can be obtained.

Further, since the compounded feed containing flaxseed has a small amount of odorous components, it has a high palatability for birds and has an advantage of enhancing feeding efficiency and egg laying rate.
