Abstract

PURPOSE:To produce the subject additive capable of promoting control of intestinal function of livestock, of reducing crisis of diarrhea thereby and of, therefore, increasing the amount of milk, etc., by removing components soluble in water, alcohol, acetone or a mixture solution thereof from tea leaves and using the resultant tea leaf fibers as the active component. CONSTITUTION:Ground tea leaves are extracted with 5 to 20 times amount of water, alcohol, acetone or a mixture solution thereof. The resultant tea leaf fibers as the extraction residue obtained by removing soluble components from the tea leaves are used as the active component. This additive is added generally in an amount of >=0.01wt.% based on a livestock feed.

Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention promotes the intestinal regulating action of an animal, reduces the occurrence of diarrhea, and increases the milking amount by incorporating tea leaf fiber into the animal feed for dairy cows, beef cattle, pigs, chickens and the like. ，
The present invention relates to an additive for livestock feed, which has an effect of improving feed efficiency and eliminating odor of feces and urine.

2. Description of the Related Art Livestock such as dairy cattle, beef cattle, pigs, and chickens have been used more and more in recent years, and tend to be fed with concentrated feed to improve the economic effect in order to improve productivity. The burden on the gastrointestinal tract is greater than that of other feeds, which causes problems such as a decrease in the growth rate of livestock, a decrease in milking amount, and a deterioration in meat quality. Further, due to the concentration of the breeding environment, the chances of developing bacterial or viral diarrhea due to various factors such as stress are increased, which causes obstacles to the maintenance of the barn, which is a big problem for the industry. The administration of antibiotics and powerful antibacterial agents against diseases has many problems such as disturbing the digestive organs and intestinal bacterial flora of livestock and inducing new diseases, and the retention of these drugs in milk and meat. There are concerns such as a decrease in product value and safety concerns as pointed out. On the other hand, manure and odors generated from livestock sheds have a large impact on the surrounding environment, and especially in diarrhea stools, the bad odor becomes a strong problem and causes bad odor pollution, but at the moment we cannot find an effective solution. is there.

[0003]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention As a result of studies on the improvement of the above problems, the present inventors have found that, unlike conventional feed additives, tea leaves are dissolved in water, alcohol, acetone or a mixed solution thereof. By administering to the livestock animal an additive for livestock feed containing the tea leaf fiber from which the active ingredient has been removed, the intestinal function of the livestock animal is promoted and the onset of diarrhea is reduced.
Increase milk production, improve feed efficiency,
The present invention has been completed by discovering that the odor eliminating effect of urine is observed.

[0004]

Means for Solving the Problems As a result of various investigations on a plant-derived component of a substance which is safe and can be administered for a long time and has the above-mentioned effects, tea leaves derived from tea which we drink daily. We have found that the fibers have the above-mentioned effects. The tea leaf fiber used in the present invention can be obtained as an extraction residue obtained by removing soluble components obtained by extracting pulverized tea leaves with 5 to 20 times the amount of water, alcohol, acetone or a mixed solution thereof. Here, the alcohol is not particularly limited, but methanol, ethanol, propanol, isopropanol, butanol and the like are preferable. The tea leaves used as a raw material may be from any stage of a normal production process, from fresh leaves to finished tea (dry tea), and regardless of the degree of fermentation, unfermented tea, semi-fermented tea, or fermented tea can be used. There is no particular problem in heating during extraction, and in the case of water extraction, it is preferable to heat at 60 ° C or higher, preferably 75 to 90 ° C for 0.5 to 2 hours. Usually, when 10 kg of tea leaves are extracted with 50 to 200 kg of water, the extraction residue is 20 to 40 kg and B is added depending on the amount of water added.
40 to 160 kg of extracts of rix 2 to 10 are obtained.
The obtained extraction residue can be dried by a commonly used method, for example, hot-air drying, freeze-drying, etc., then pulverized and mixed with the feed. Thus, 6 to 8 kg of tea leaf fiber is obtained from 10 kg of tea leaf. The obtained tea leaf fiber has about 70% or more of caffeine and tea polyphenol compounds removed as compared with the raw tea leaf, so bitterness and astringency are reduced and taste is improved, and it is more suitable as a feed additive. .
On the other hand, tea polyphenol compounds have useful properties such as antioxidative properties and antibacterial properties and are highly safe, and various application developments based on these are underway, and at the same time, their industrial manufacturing methods are being established. is there. Here, the production of the tea leaf fiber of the present invention can be combined with the above-mentioned production method of the tea polyphenol compound, and thereby the productivity of each production method is enhanced, which is also one of the features of the present invention. The amount of tea leaf fiber added to livestock feed is usually 0.
It is desirable to set it to 01% or more. There is no particular limitation on the method of adding the tea leaf fiber to the feed, and any method can be used as long as it can be appropriately added during each manufacturing process and is orally administered. Hereinafter, the present invention will be described in detail with reference to examples. However, the present invention is not limited to these examples.

【Example】

Example 1. Preparation of Tea Leaf Fibers 10 L of water was added to 1 kg of tea leaves that had been pulverized with a power mill and passed through a filter having a diameter of 1.5 mm, and the mixture was mixed at 90-95.
Heat at 30 ° C. for 30 minutes. The mixture was subjected to solid-liquid separation to obtain 2.4 kg of a wet residue and 8.6 kg of an extract of Brix4. The wet residue was dried at 70 ° C overnight and then crushed to form tea leaf fiber 70.
0 g was obtained. The contents of caffeine and tea polyphenol in this tea leaf fiber were as low as 0.6 g and 2.7 g per 100 g, respectively, and there was little bitterness and bitterness, and they could be sufficiently added to the feed.

Example 2. Preparation of tea leaf fiber 200 g of a mixture of sencha and oolong tea (3: 1) has a diameter of 2 to
The mixture was crushed to 3 mm, added with 4 L of a mixed solution of water, ethanol, and acetone (5: 3: 2) heated to 50 ° C, and extracted for 2 hours.
The mixture is subjected to solid-liquid separation, and 320 g of the obtained wet residue is
After drying with hot air at ℃, it was pulverized to obtain 150 g of tea leaf fiber.
This tea leaf fiber has almost no astringency and bitterness,
It could be added sufficiently.
