BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feed for eggs, which contains red yeast rice, and a method for producing eggs, which comprises feeding it to the eggs.

[0002]

2. Description of the Related Art Hypercholesterolemia is known to cause heart diseases such as arteriosclerosis, angina, and myocardial infarction, and is one of the diseases that is rapidly increasing year by year. One of the causes is excessive intake of animal foods with high cholesterol content. Among them, chicken eggs, which are used by many people as daily food, are foods with high cholesterol content (thousands of hundreds of mg / 100g). Is well known as Although chicken eggs are said to be nutritionally well-balanced foods, they tend to suppress intake of cholesterol in order to avoid excessive intake of cholesterol, and have one aspect that is incompatible with health-conscious foods. Therefore, if chicken eggs with low cholesterol content can be produced, it not only helps prevent hypercholesterolemia but also has a great effect on nutrition intake. For this reason, research on the production of low-cholesterol poultry eggs and other cholesterol-reducing substances has been conducted.
Many inventions have been made. For example, JP-A-54-29772 discloses "a method for producing low-cholesterol eggs in poultry by administering ML-236A, ML-236B or a derivative thereof".
However, Japanese Patent Laid-Open No. 63-269967 discloses "a method for producing a pickled roe which has a low cholesterol content and can reduce cholesterol in the human body", in Japanese Patent Laid-Open No. 05-8
No. 25702 and Japanese Patent Publication No. 10-820150, “Method of producing cholesterol-reducing substance by enzyme treatment”
However, JP-A No. 11-332518 describes "a method for producing low-cholesterol egg yolk by improving the edible oil / fat extraction method".

DISCLOSURE OF THE INVENTION The present invention provides a feed for hens and a method for producing hens characterized by administering the feed, thereby providing a nutritionally balanced and excellent food while maintaining good health. It is intended to reduce and improve the high cholesterol property of chicken eggs, which is shunned as a food, and to help prevent hyperlipidemia.

[0004]

[Means for Solving the Problems] That is, the present invention provides: 1. A feed for an egg-laying chicken, which contains red yeast rice. Item 2. The content of red yeast rice is 0.1 to 10% by weight, Item 1.
The feed for egg-laying chicken as described in. Item 3. An egg obtained by feeding red yeast rice. It is characterized by.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The Aspergillus oryzae of red mold as used in the present invention may be any filamentous fungus belonging to the genus Monascus. Variants and mutants are mentioned, and Monascus pylosus is particularly preferable.
The raw material for red yeast rice may be any raw material that can be used for the preparation of koji, and examples thereof include rice, soybean, wheat, and germ. These may be used alone or in combination of two or more kinds. . Further, as a culturing method, either a solid culturing method or a liquid culturing method can be adopted, and the culturing condition can be any condition as long as the red mold is propagated. The method of feeding red yeast rice to eggs for chickens is red yeast rice produced by solid culture, heat sterilized red yeast rice yeast fungus, dried and pulverized powder, red yeast rice extract extracted by a conventional method, and further liquid culture. The red malt produced in 1. can be added to the feed by being powdered by a spray drying method or the like, but in addition to this, a liquid culture solution, or an extract, powder or the like is directly added to water to be used as drinking water. May be given. The feed to which red yeast rice is added may be any feed as long as it can be fed to chickens, and for example, it is appropriately added to a commercially available feed used in general. In addition, the amount of red yeast rice added to such feed is 0.1 to 10 relative to the weight of the feed.
The range of% is particularly preferable. That is, if it is less than 0.1%, the yolk cholestail is less likely to decrease, and if it exceeds 10%,
Since the nutritional balance as a feed is lost, it affects egg weight, egg collection rate, etc. Examples will be described below.

[0006]

Example 1 Polished rice was immersed in water overnight, drained for 30 minutes, and sterilized by steaming at 121 ° C for 20 minutes in an autoclave to obtain steamed rice. A mutant strain of Monascus pilosus IFO4520 (XI-48) was inoculated into this and cultured aerobically at 30 ° C for 14 days to obtain red yeast rice. The red yeast rice was heat-treated at 105 ° C. for 20 minutes to deactivate the red yeast rice bacteria and the enzyme, dried at 70 ° C. with ventilation to a water content of 8%, and further pulverized to obtain red yeast rice powder. A weight ratio of this red yeast rice powder to a compound feed for adult chicken breeding (product name: Kumiai Adult Chicken No. 17) manufactured by JA West Japan Kumiai Feed Co., Ltd.
Add 5 and 2.5% ratio, mix well, each treatment section 5
Feathered chickens (white leghorns) were fed. Cholesterol oxidase was used to determine the cholesterol content of egg yolk
-The result measured by the phenol method is shown in Table 1. According to this, the cholesterol content in the egg yolk decreased from the second week after the addition of red yeast rice, and a constant decrease was recognized from the sixth week onward. There was no difference in egg collection rate, feed intake, and body weight between the plots.

[0008]

The feed for egg-laying chickens of the present invention and the eggs obtained by the egg production method characterized by feeding the feed to chickens have low cholesterol and are effective in preventing hyperlipidemia.
