Abstract

PURPOSE:To obtain egg of domestic fowl containing low total cholesterol amount and large amount of high-density lipoprotein(HDL) and lecithin by administrating Eucommia ulmoides olive to domestic fowl laying egg. CONSTITUTION:The aimed egg is obtained by administrating Eucommia ulmoides olive to domestic fowl laying egg (e.g. garden fowl, domestic duck, goose, turkey, wild duck, crossbreed of wild and domestic ducks, pheasant, quail or guinea fowl). Besides, adding amount of Eucommia ulmoides olive to feed is preferably 2.5-5.0wt.%.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a poultry egg with a low content of total cholesterol and a high content of high density lipoprotein (HDL) cholesterol and lecithin, and a method for producing the same.

The poultry eggs provided by the present invention have a total cholesterol content reduced by about 20% or more compared to ordinary eggs, and HDL cholesterol and lecithin contents are increased by about 32% and 12% or more, respectively. ing. Therefore, the poultry eggs of the present invention can be used as health food or food for patients.
Or used as raw material. Furthermore, the present invention relates to a method for improving productivity of poultry eggs. According to the method of the present invention, it is possible to improve the egg-laying rate and the amount of eggs laid by poultry, and it is also possible to reduce the feed conversion rate.

[Prior art and its problems] Poultry eggs, especially chicken eggs, are highly nutritious and excellent protein foods, but because of their high total cholesterol content, they are not recommended as food for people suffering from or at risk of hypercholesterolemia. is not suitable. Therefore, while preserving the nutritional value of eggs, only the total cholesterol content is reduced. That was what was hoped for.

Conventionally, a method of administering other sterols similar to cholesterol to poultry is widely known as a method for reducing the total cholesterol content of poultry eggs. This takes advantage of the fact that other sterols are mistakenly incorporated into eggs instead of cholesterol. Although it is possible to obtain eggs with a low total cholesterol content by this method, it is difficult to obtain large amounts of sterols, and it is a very expensive drug, so it has not been put to practical use.

Furthermore, from the viewpoint of prevention of adult diseases and beauty, there is a desire for foods with a high content of HDL cholesterol, so-called good cholesterol, and lecithin, but hitherto no method has been known to increase the content of these components in poultry eggs.

Furthermore, since egg productivity decreases as poultry ages, it is desirable to delay aging and actively improve productivity.

[Means for Solving the Problems] The problems of the prior art described above are solved by the present invention, which involves administering Mori to poultry.

That is, the present invention comprises poultry eggs with low total cholesterol content and high HDL cholesterol and lecithin content obtained by administering betel to egg-laying poultry, and a method for producing the same. Furthermore, the present invention comprises a method for improving the productivity of poultry eggs by administering betel to egg-laying poultry. In Chinese medicine, Du Zhong is Eucoimla ul, a tree native to China.
In the present invention, the term ``Midzhong'' refers to the dried bark of Euconium moldes (family Eucommaceae).
() Used as a botanical name to mean the family Tuaceae).

In the present invention, the bark, leaves, or root bark of Moriflora can be used, and usually its dried product, extract, or dried product of its extract is used. Approximately 80 to 120
Roasting at ℃ for about 0.5 to 2 hours can eliminate the odor of Mori. For economic efficiency and convenience of handling, dried powdered leaves of Duchuan are preferred.

In the present invention, poultry broadly refers to birds kept by humans for the purpose of collecting eggs, such as chickens, ducks, geese, turkeys, ducks, ducks, pheasants, quail,
Examples include guinea fowl and crow fowl.

It is appropriate to administer Mori Zhong by adding its dry powder to the feed, and the amount added is about 0.1 to 100% of the total amount of feed.
30%, preferably 2.5-5.0% (vlv). The dosage is not critical and will vary depending on the type of poultry, but approximately 1.7 mg per day as a dry powder of Duchu leaves.
~3.4g/kg. For example, when administering to chickens, approximately 1% of the total amount of feed should be added to the dried powder of Morifolia leaves.
It is added to a concentration of ~5% (νh), about 1.5% per day.
Feed intake for chickens is approximately 7 to 3.4 g/chicken per day.
0-120g/wing).

[Effects of the invention] Eggs obtained by administering betel to poultry have a low total cholesterol content, about 80% of the total cholesterol content of normal eggs.
It is as follows. In addition, HDL cholesterol content is 32%
As mentioned above, the lecithin content is 12% or more. Furthermore, when administered to poultry, Du Zhong can slow down the aging process.
Egg productivity can be improved. For example, if you administer Du Zhong to egg-laying hens, the egg production rate will increase by 25% or more, and the amount of eggs will decrease by 1.
The present invention will be explained in more detail with reference to Examples and Test Examples.

Example 1 Fourteen hens of the Shaver variety aged 398 days after cape formation were divided equally into a test group and a control group, and each group was placed in a cage (23×41
The animals were kept in a 40cm x 40cm cage. The test group was fed commercially available adult chicken feed (CP17% or higher, ME2850kcaII).
The chickens were reared for 24 weeks with ad libitum feed to which 5% (vlv) of dried Duchu leaf powder was added to the chickens (more than 1 kg), and the control group was fed the commercially available adult chicken feed mentioned above without the addition of Du Chuchu leaf powder.

During this period, egg production rate, egg production, feed conversion rate, total cholesterol, HDL cholesterol level, and lecithin content of eggs were measured and recorded every week. Cholesterol values were extracted with a chloroform-methanol solution and measured using a gas chromatograph. Table 1 shows the average values from 3 to 23 weeks after administration of Tochu.

(Margins below) In Table 1, the numbers in parentheses indicate the respective measured values at the start of the test.

From Table 1, it is clear that in the test group, the egg production rate and egg production were higher than at the start of the test, and the feed conversion rate was low. On the other hand, in the control group, the egg production rate and egg production were low and the feed conversion rate was high. This means that in the control group, the egg production rate, egg production, and feed conversion ratio deteriorated due to aging of the chickens, whereas in the test group, aging of the chickens was prevented and further improvements were made. It means that there is.

Furthermore, the total cholesterol levels of eggs in the test group were reduced by about 25% in both egg yolks and whole eggs compared to the control group.

Furthermore, lecithin and HDL cholesterol in egg yolks in the test group were 13% and 13%, respectively, compared to those in the control group. 32
．． It has increased by 85%.
