Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low cholesterol feed for poultry and livestock in which cholesterol in poultry eggs and meat produced is reduced by feeding laying hens and poultry livestock for meat. .

[0002]

2. Description of the Related Art In recent years, the number of health-sensitive consumers has increased,
In the poultry livestock market, research is generally conducted to reduce the cholesterol level of poultry livestock products such as eggs and to increase linolenic acid by changing the composition of poultry livestock feed.

[0003] Fibers contained in food or feed for humans and animals are supposed to embrace cholesterol and bile acids, particularly depending on their hydration ability, thereby exerting an action of reducing their absorption. Fibers such as loglucan, salep root powder, karaya gum, agar, and alginic acid have been tested in laying hens, but no clear conclusions have been reached, including the opposite results for egg yolk.

[0004] As a feed component effective for lowering the cholesterol of such poultry and livestock products, beta-sitosterol as a plant sterol has attracted attention, and has been isolated and purified.
It has been used as a compounding agent to add small amounts to feed.

[0005] On the other hand, deodorized scum oil generated in the edible vegetable oil refining process was originally a by-product in the refining process, and thus was not actively used except as a raw material for extracting vitamin E.

[0006]

Since plant sterols effective for lowering cholesterol are specifically isolated and purified from deodorized scum oil and the like, they are extremely expensive, about 15 times that of the raw material deodorized scum oil. .

[0007] In addition, there is also a problem that a component of a plant sterol which has been specially purified is inefficient when used alone.

On the other hand, deodorized scum oil contains natural tocophere, linoleic acid, linolenic acid and the like in addition to plant sterols. For this purpose, a synergistic effect of plant sterol and natural tocopher, linoleic acid, linolenic acid, etc. can be expected.

[0009]

DISCLOSURE OF THE INVENTION The present invention addresses the above-mentioned problems and is not a plant sterol isolated and purified from a low cholesterol reduced poultry feed, but a deodorant generated in the process of refining edible vegetable oil. The scum oil itself is used.

[0010] Furthermore, it is difficult to mix deodorized scum oil produced in the process of refining edible vegetable oil with feed such as corn or soybean meal in a liquid state, so it is difficult to form the deodorized scum oil into a predetermined form. The composition is adsorbed on the inorganic excipient, thereby facilitating the compounding operation and also facilitating the ingestion of livestock and the like.

[0011]

[Action] By continuously feeding feed containing plant sterols and components such as natural tocopher, linoleic acid and linolenic acid to poultry and livestock such as laying hens, one of the components is plant sterol, which is cholesterol. Has the effect of inhibiting the absorption of.

Further, linoleic acid and linolenic acid, which are other components, synergize with the action of plant sterols, and as a result, lower cholesterol in products such as poultry eggs and animal meat.

[0013]

Embodiments of the present invention will be described below. Refining of edible vegetable oil involves adding phosphoric acid to crude oil to separate gum, and then filtering the oil layer that has been deoxidized, decolorized, and deodorized sequentially with alkali and clay, but deodorized scum oil in the deodorization step. Occurs.

This deodorized scum oil may be fed as it is to poultry and livestock, but since it is oily and difficult to accept, it is easy to give it in combination with general feed.

However, there are various types of poultry and livestock, and their feeds vary widely. For example, a common feed for laying hens is 58% corn, 10% koulyang, 15%
% Gluten meal, meat-and-bone meal, fish meal, vitamins, minerals, salt, and calcium carbonate.

[0016] Mixing oily liquid deodorized scum oil with such laying hen feed is not suitable for sticky feeding.

[0017] Therefore, a method in which the deodorized scum oil is directly dissolved and sprayed on a feed to be adsorbed, and a method in which the deodorized scum oil is added using rice bran oil scum, corn yumir, soybean oil scum, potato pulp or the like as an excipient. For example, an appropriate method is selected and blended according to the type of poultry and livestock and the form of feed.

Furthermore, inorganic excipients such as silicic anhydride have an extremely high adsorption rate as compared with organic excipients, and can be processed into morphological forms. It can correspond to the form of the feed and is easy to mix with the feed.

[0019]

Industrial Applicability Since the present invention is constituted as described above, deodorized scum oil which is a by-product generated in the process of refining edible vegetable oil can be positively utilized as a low-cholesterol feed for poultry and livestock. The health of the livestock itself can be promoted, and the cholesterol of the livestock products can be reduced.

Furthermore, it is possible to provide low-cost cholesterol-reduced chicken eggs and meat, which have been conventionally regarded as expensive, at a low price, and it is possible to recover the demand which has become distant from livestock products due to concerns such as high blood pressure.

Claims (3)

(57) [Claims] 1. A feed for poultry and livestock with low cholesterol using deodorized scum oil generated in the process of refining edible vegetable oil. 2. The cholesterol-reduced poultry feed according to claim 1, wherein deodorized scum oil generated in the process of refining edible vegetable oil is added or blended into the feed. 3. The method according to claim 1, wherein the deodorized scum oil generated in the process of refining the edible vegetable oil is adsorbed on the inorganic excipient.
Low cholesterol feed for poultry and livestock as described
