Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an animal feed additive.

[0002]

2. Description of the Related Art Conventionally, various additives have been proposed as animal feed additives. For example, powder of at least one plant selected from the group consisting of ginseng, watermelon, loofah, amachazur, cucumber, melon, liquorice, soybean, psycho, adzuki bean and tea leaves, and / or a plant extract and / or fermentation product extracted from the plant are essential. Feed for improving meat quality as a component (see Japanese Patent Application Laid-Open No. 61-119144), black pepper, clove, ginger, garlic, onion, and feed for livestock meat containing one or more of these essential oils A method for improving the meat quality of livestock, comprising mixing a material containing an agent (see JP-A-5-276878), tannin, caffeine and the like into a normal feed and feeding the mixed feed to the livestock ( Japanese Patent Laid-Open No. 6-209720) is known. All of these prior arts have been developed for use in limited applications.

[0003]

The inventors of the present invention have conducted various studies on highly versatile feed additives that can be used for multipurpose purposes, and as a result, completed the present invention.

[0004]

Means for Solving the Problems That is, the present invention relates to Pine Needle, Hawthorm Fruit, Okera (Bighead Atractylodes Rhizome), Milk Vetch.
An animal feed additive comprising at least one herb selected from (Milkvetch Root), Ezonamiki (Skullcap Root), Chimpi (Tangerine Fruit) and Mint (Mint Siftings).

[0005]

Next, the present invention will be described in more detail. In the present invention, ginger, hawthorn, oakera,
When using a herb consisting of milk vetch, edible mushroom, chimney and mint, it is used as it is, but it can also be used in the form of crushed or essential oil as appropriate. These herbs can be used alone, but the effect is preferably improved by using three or more kinds in combination.

In this case, the amount of the herb used in the feed is preferably 0.01 to 5% by weight. The animal feed additive of the present invention can also be directly fed without adding to the feed.

[0007] When the essential oil of herb is used in the present invention, it may be added and mixed into the feed as it is, for example, glycerin medium-chain fatty acid ester, soybean oil, corn oil,
Added to oils and fats such as rapeseed oil, beef tallow and lard (Essential oil content 2
(0 to 50% by weight) and then adsorbed (preferably 1 to 10% by weight of essential oil) on powders such as corn flour, wheat flour, bran, and defatted rice bran, because they can be uniformly mixed with feed.

In this case, for example, in the case of essential oil, the amount used in the feed is preferably 0.001 to 1% by weight, and the amount of the essential oil-adsorbed powder used in the feed is 0%. It is preferably about 0.01 to 10% by weight.

In the present invention, the above herbs can be used alone or in an appropriate combination depending on the purpose of use. When two or more kinds of herbs are used, they can be usually mixed in an equal amount and used, but it is preferable to appropriately adjust according to the use.

[0010] By feeding the animal feed additive of the present invention to an animal, a meat odor-correcting effect, an anti-disease effect, an antibacterial effect, an immunostimulating effect, a hormone regulating effect, an antioxidant effect,
Various effects such as a microbial growth inhibitory effect, a stomachic effect, a metabolic regulation effect, and an appetite enhancing effect can be obtained.

The above-described various effects can be obtained by adding the animal feed additive of the present invention to a feed and ingesting it to chickens, pigs, cows, etc. for at least two weeks.

[0012]

Next, the present invention will be described in more detail by way of examples.

Example 1 An animal feed additive was prepared by mixing equal parts of ginger, hawthorn, oakera, milk vetch, Ezonamiki, chimney and mint.

Example 2 An animal feed additive was prepared by mixing equal parts of fruit flies, mint and hawthorn.

EXAMPLE 3 An animal feed additive was prepared by mixing equal amounts of Milk Vetch, Chimney and Ezonamiki.

Example 4 Milk vetch, oakella, hawthorn and ginger were mixed in equal amounts to prepare an animal feed additive.

Test Example 1 Three test plots were prepared with 15 21-day-old LW castrated male pigs (body weight: about 6 kg), 15 test plots per plot. The test pigs were fed with a basic feed shown in Table 1 below and a predetermined amount of the animal feed additive prepared in Example 1 and fed and raised for 35 days to examine the growth improving effect. The basic feed fed was used as the basic feed A until the 21st day from the start of the test, and thereafter, the basic feed B was used. For comparison, a group without addition of the animal feed additive was tested as Comparative Example 1, and a group using an antimicrobial agent instead of the animal feed additive was tested as Comparative Example 2. The "feed requirement rate" in the table indicates a value obtained by dividing the daily feed intake by the daily gain. Next, these test results are shown in Table 2.

[0018]

[Table 1]

[0019]

[Table 2]

The kind of the antibacterial agent of the basic feed A used in Comparative Example 2 and the content in the feed were 12 g of ephrotomycin.
Titer / ton, colistin sulfate 40 g titer / ton and morantel citrate 30 g / ton, the type of antibacterial agent of the basic feed B and the content in the feed were ephrotomycin 6
g titre / ton, olaquindox 50 g titre / ton and Morantel citrate 30 g / ton.

As is clear from the results in Table 2, the group in which 0.25% by weight of the animal feed additive was added had a higher growth improving effect than the group without the animal feed additive (Comparative Example 1). The effect is equal to or higher than that of the group using the antibacterial agent (Comparative Example 2).

Test Example 2 The animal feed additive and antibacterial agent used in Test Example 1 were the same as in Test Example 1, except that the test plot was divided into two plots, the basic feed A was used as the basic feed, and the test period was set to 21 days. Tested using Table 3 shows the test results.

[0023]

[Table 3]

Test Example 3 Two days old young chicks (variety decarb) were used as test plots in one plot.
Two wings were provided as wings. The test chickens were fed with the basic feed shown in Table 4 below, to which 1% by weight of the animal feed additive prepared in Examples 2 to 4 was added.
The antigen Bordetella bronxeptica H16 killed bacterium) was intravenously administered, and 4 days after the administration, the effect of enhancing antibody production was examined. The antibody titer is a value obtained by measuring the agglutinated antibody titer of the serum by a microtiter method. Table 5 shows the test results.

[0025]

[Table 4]

[0026]

[Table 5]

Test Example 4 The animals were bred in the same manner as in Test Example 3. Escherichia coli (Escherichia coli 17-35 strain) was intravenously administered on the 21st day from the start of the test, and the mortality for 4 days from the day after the administration was measured. Examined. The mortality rate is a value indicating the percentage of dead chicks to feathers (50 birds) per section as a percentage. Table 6 shows the test results.

[0028]

[Table 6]

Various tests were conducted in the same manner as described above, using the animal feed additive of the present invention alone. As a result, an excellent effect was obtained as a result of performing an antimicrobial test using Shoyo and Ezonamiki. As a result of an immunostimulating effect test using Okera and Milk Vetch, an excellent immunostimulating effect was recognized. As a result of testing the change in the amount of food consumed using a cock, an excellent improvement in the amount of food consumed was recognized. An anti-respiratory disease test was performed using a tipi and a mint, which showed an excellent effect. Tests with or without hormonal regulation using hawthorn, oakella and milkvetch showed excellent regulatory effects.

[0030]

When the animal feed additive of the present invention is supplied, various effects such as meat odor correction, anti-disease, antibacterial and immunostimulatory effects can be obtained.
