Description

【0001】
【発明の属する技術分野】
本発明は、ヒト並びに鶏等の家禽等の動物の飢餓時における傷害を防御する防御剤、及び鶏などの家禽の強制換羽方法に関する。
【0002】
【従来の技術】
産卵鶏は日齢が進むと産卵率が徐々に低下し、卵重が大きくなってかつ破卵しやすくなり、商品価値の低い卵の率が多くなる。このような鶏において、一定期間飼料の給与又は飼料と飲水の両方の給与を停止し、産卵を停止させ、羽が抜け落ちた後再び給餌を開始することにより、鶏の身体を再生させることが行なわれている。この処理は、強制換羽と呼ばれている。強制換羽は、卵の生産の経済性を高めるため、産卵鶏産業において広く行なわれている。
【0003】
強制換羽処理を施した鶏群においては産卵率及び卵の品質が向上した個体が多く現れるが、一方、飼料給与の停止に伴ないダメージを受け、死亡したり産卵不能となったりする個体も現れる。また、かかるダメージによる有害菌への防御機能の低下により、卵の汚染を引き起こす可能性が高くなるという不都合も起こりうる。したがって、鶏等の家禽において、ダメージを与えずに有効な強制換羽を行なうための手段が求められている。
【0004】
ところで、鶏の雛において、サルモネラ菌の増殖を抑制する目的で、ラクトバチルス・ロイテリ等の乳酸菌を投与することが知られている(特許文献1及び特許文献2)。しかしながら、成鶏において、強制換羽処理のダメージを抑制する目的で乳酸菌を投与することについては、これまで知られていない。
【0005】
また、ヒトにおいて、美容上等の目的により食事を減量したり絶食することが行なわれるが、その場合においても、鶏の強制換羽の場合と同様に、減食又は絶食によるヒトへのダメージがある。かかるダメージを防御することができれば、美容上等において有利な価値がある。

【発明が解決しようとする課題】
本発明の目的は、家禽にダメージを与えずに有効な強制換羽を行なうための強制換羽方法、及びそのための強制換羽補助剤を提供することにある。
【0007】
本発明の別の目的は、動物において減食又は絶食によるダメージを防御できる防御剤を提供することにある。
【0008】
【課題を解決するための手段】
本発明者らは上記課題を解決するため種々検討した結果、強制換羽処理を施した家禽の腸管には重度の細胞の傷害があること、及び強制換羽時等の動物の飢餓時の傷害は、飢餓に伴ない特定の成分を含む防御剤を投与することにより著しく改善され、飢餓時における傷害自体も改善されることを見出し、本発明を完成した。
【0009】
即ち、本発明によれば、乳酸菌を有効成分として含む強制換羽傷害防御剤が提供される。
【0010】
また、本発明によれば、家禽を絶食させる工程と、前記強制換羽傷害防御剤を前記家禽に投与する工程とを含むことを特徴とする強制換羽方法が提供される。
【0011】
さらに、本発明によれば、乳酸菌を有効成分として含有する飢餓時傷害防御剤が提供される。
【0012】
【発明の実施の形態】
本発明の強制換羽傷害防御剤又は飢餓時傷害防御剤は、乳酸菌を有効成分として含有する。本発明の防御剤において、前記乳酸菌は、投与対象に生菌として投与される態様であることが好ましい。
【0013】
前記乳酸菌は、成鶏由来の乳酸菌であることが、動物に定着し易く且つ水道水中に懸濁して投与する場合に死滅しにくいため好ましい。成鶏の飼育においては通常一般的な水道水が飲水として給水されるので、水道水中に懸濁して投与する場合に死滅しにくい菌であることは、飲水中に添加して投与する場合に特に有利である。
【0014】
前記乳酸菌としては、ブドウ糖から乳酸のみを産生するホモ型乳酸菌と、ブドウ糖から酢酸等乳酸以外の物質をも産生するヘテロ型乳酸菌とを組み合わせて含むことが、腸管を傷めることなく幅広く腸内に乳酸菌を分布させることができるため好ましい。
【0015】
前記ホモ型乳酸菌としては、ラクトバチルス・カゼイ(Lactobacillus casei)、ラクトバチルス・プランタラム(L.plantarum)、ラクトバチルス・アシドフィルス(L.acidophilus)、及びラクトバチルス・サリバリウス(L.salivarius)等を挙げることができ、ラクトバチルス・サリバリウスが特に好ましい。
【0016】
また、前記ヘテロ型乳酸菌としては、ラクトバチルス・ロイテリ(L.reuteri)、及びラクトバチルス・ファーメンタム(L.fermentum)等を挙げることができ、ラクトバチルス・ロイテリが特に好ましい。
【0017】
前記ラクトバチルス・サリバリウスとしては、ラクトバチルス・サリバリウスLH8株(独立行政法人 産業技術総合研究所 特許生物寄託センター 寄託番号FERM P−19181 寄託日平成15年1月8日)を好ましく用いることができ、前記ラクトバチルス・ロイテリとしては、ラクトバチルス・ロイテリNHL2株(独立行政法人 産業技術総合研究所 特許生物寄託センター 寄託番号FERM P−19182 寄託日平成15年1月8日)を好ましく用いることができる。
【0018】
本発明の防御剤は、前記乳酸菌に加えて、腸内乳酸菌増殖性のオリゴ糖をさらに含むことができる。前記オリゴ糖としては、消化酵素により分解されず、且つ乳酸菌に利用されやすい、乳酸菌の増殖を促進するオリゴ糖を挙げることができ、より具体的には例えば、ガラクトオリゴ糖類、フラクトオリゴ糖類、キシロオリゴ糖類等又はこれらの混合物等を挙げることができる。本発明の防御剤において、前記乳酸菌に対する前記オリゴ糖の配合割合は、総乳酸菌1CFUあたり0〜150mgとすることができる。オリゴ糖を含むことにより、小腸では腸管壁に付着・定着した乳酸菌の死滅を防いでアルカリ性の腸液・膵液を中和する作用を増強し、大腸では乳酸菌の増殖を促進して有害菌を抑制する。
【0019】
本発明の防御剤中の前記乳酸菌の含有割合は、特に限定されないが、後述する好ましい投与量で投与するのに適した含有割合とすることができる。
【0020】
本発明の防御剤の投与量は、1日当り家禽等の被検者動物の体重kg当り、乳酸菌の総菌数として10CFU〜5×10CFUとすることができる。また、乳酸菌としてホモ型乳酸菌とヘテロ型乳酸菌とを組み合わせて含む場合、それぞれを1日当り家禽体重kg当り10CFU〜10CFUとすることができ、また、ホモ型とヘテロ型の比率は1:1に限定されない。
【0021】
本発明の防御剤の投与対象は、ヒト並びに鶏等の家禽等の動物である。特に、産卵量の減少した、日齢400日以上の鶏等の家禽、並びに美容上の目的により減食又は絶食しているヒトに対し、好ましく投与することができる。
【0022】
いかなる理論にも拘束されないが、本発明の防御剤の投与により強制換羽又は減食・絶食による傷害が防がれる作用機序は、絶食等に伴なう腸管壁細胞の傷害の防止によるものであることが考えられる。動物の腸液・膵液はアルカリ性であり、また、これに含まれる代表的なタンパク質分解酵素であるトリプシン、キモトリプシンの至適pHはアルカリ側にある。動物が飢餓状態におかれると、腸液・膵液のタンパク質分解酵素は、腸管壁の絨毛細胞の構成タンパク質を分解し、結果として、腸管壁細胞の壊死や脱落剥離を促進する。ここで、それぞれ小腸及び大腸の腸管壁に付着・定着し易いヘテロ及びホモ乳酸菌を投与することにより、腸管壁に付着した乳酸菌の分泌する乳酸が、腸液・膵液のアルカリ性を中和して、タンパク質分解酵素が腸管壁細胞を分解することを防ぎ、結果として飢餓時の腸管壁細胞の壊死や脱落剥離を防止し、ひいては強制換羽時等の減食・絶食時の傷害を防ぐという作用機序が考えられる。
【0023】
本発明の強制換羽方法は、鶏等の家禽を絶食させる工程と、前記防御剤を前記家禽に投与する工程とを含む。
【0024】
前記絶食の期間は、特に限定されず、強制換羽による再生の効果が良好に得られるよう適宜調節することができるが、6日〜14日とすることができる。また、絶食は、飼料の給餌を停止し飲水はさせることが好ましいが、栄養の無い飼料を給餌することもできる。後者の場合は、前記本発明の防御剤を飲水・栄養の無い飼料のどちらに混入してもよい。
【0025】
前記防御剤の投与期間は、特に限定されず、絶食開始前、絶食期間中及び絶食終了後のいずれか一以上の期間内に投与することができるが、絶食開始前から投与を開始し、絶食期間中にわたり投与を継続することが好ましい。具体的には例えば絶食開始3日前から絶食終了後3日にわたって投与することができる。さらに、絶食開始前と絶食期間中とで、防御剤の投与量を変更することもでき、オリゴ糖等の成分の有無及び配合割合等を変更することもできる。前記防止剤の投与量は、本発明の防御剤の前記好ましい投与量の範囲内とすることができる。
【0026】
【発明の効果】
本発明の強制換羽傷害防御剤及び強制換羽方法は、それを投与又は実行することにより、家禽にダメージを与えずに有効な強制換羽を行なうことが可能となり、また、家禽腸内の有害菌増殖を抑制する効果も併せて期待でき、卵の生産量、品質、安全性等を向上させることができる。
【0027】
また、本発明の飢餓時障害防御剤は、動物において減食又は絶食によるダメージを効果的に防御することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a protective agent that protects humans and animals such as chickens such as poultry from starvation, and a method for forced molting of poultry such as chickens.
[0002]
[Prior art]
As the age of laying hens progresses, the egg-laying rate gradually decreases, the egg weight increases and it becomes easy to break, and the rate of eggs with low commercial value increases. In such chickens, the body of the chicken is regenerated by stopping the feeding of feed for a certain period or both feeding and drinking water, stopping egg laying, and starting feeding again after the wings fall off. It is. This process is called forced molting. Forced molting is widely practiced in the laying hen industry to increase the economics of egg production.
[0003]
In the flocks that have undergone forced molting treatment, there are many individuals whose egg-laying rate and egg quality have improved. On the other hand, there are also individuals who are damaged by the suspension of feed feeding and die or become unable to lay eggs. . In addition, a decrease in the protective function against harmful bacteria due to such damage may cause a disadvantage that the possibility of causing egg contamination becomes high. Accordingly, there is a need for means for performing effective forced molting without causing damage in poultry such as chickens.
[0004]
By the way, in chicken chicks, it is known to administer lactic acid bacteria such as Lactobacillus reuteri for the purpose of suppressing the growth of Salmonella (Patent Document 1 and Patent Document 2). However, it has not been known so far to administer lactic acid bacteria for the purpose of suppressing the damage of forced molting treatment in adult chickens.
[0005]
In addition, in humans, food is reduced or fasted for cosmetic purposes, and even in this case, there is damage to humans due to reduced food or fasting, as in the case of forced molting of chickens. If such damage can be prevented, there is an advantageous value in cosmetics and the like.
[Patent Document 1]
Japanese Patent No. 3215806 [Patent Document 2]
Japanese Patent No. 3028214 specification [0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a forced molting method for performing effective forced molting without damaging poultry, and a compulsory molting auxiliary for that purpose.
[0007]
Another object of the present invention is to provide a protective agent capable of preventing damage caused by food loss or fasting in animals.
[0008]
[Means for Solving the Problems]
As a result of various investigations to solve the above problems, the present inventors have found that there is severe cell damage in the intestinal tract of poultry subjected to forced molting treatment, and injuries during animal starvation such as during forced molting, The present invention has been completed by finding that it is remarkably improved by administering a protective agent containing a specific component accompanying starvation, and that the injury itself during starvation is also improved.
[0009]
That is, according to the present invention, a compulsory molting injury protective agent containing lactic acid bacteria as an active ingredient is provided.
[0010]
Moreover, according to this invention, the forced molting method characterized by including the process of fasting a poultry and the process of administering the said forced molting injury protective agent to the said poultry is provided.
[0011]
Furthermore, according to the present invention, a starvation injury protective agent containing lactic acid bacteria as an active ingredient is provided.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The compulsory molting injury protective agent or the starvation injury protective agent of the present invention contains lactic acid bacteria as an active ingredient. In the protective agent of the present invention, it is preferable that the lactic acid bacterium is in the form of being administered as a living bacterium to an administration subject.
[0013]
It is preferable that the lactic acid bacteria are lactic acid bacteria derived from adult chickens because they are easy to settle in animals and are difficult to kill when administered in suspension in tap water. In the breeding of adult chickens, generally tap water is supplied as drinking water, so it is difficult to kill when suspended in tap water, especially when added to drinking water and administered. It is advantageous.
[0014]
The lactic acid bacteria include a combination of homo-type lactic acid bacteria that produce only lactic acid from glucose and hetero-type lactic acid bacteria that produce substances other than lactic acid such as acetic acid from glucose. Can be distributed, which is preferable.
[0015]
Examples of the homo-type lactic acid bacteria include Lactobacillus casei, Lactobacillus plantarum, L. acidophilus, and L. salivarius. Lactobacillus salivarius is particularly preferred.
[0016]
Examples of the hetero lactic acid bacterium include Lactobacillus reuteri (L. reuteri) and Lactobacillus fermentum (L. fermentum), and Lactobacillus reuteri is particularly preferable.
[0017]
As the Lactobacillus salivarius, Lactobacillus salivarius LH8 strain (National Institute of Advanced Industrial Science and Technology, Patent Biological Deposit Center, Deposit No. FERM P-19181, deposited on January 8, 2003) can be preferably used. As the Lactobacillus reuteri, Lactobacillus reuteri NHL2 strain (National Institute of Advanced Industrial Science and Technology, Patent Biological Deposit Center Deposit No. FERM P-19182, Deposit Date January 8, 2003) can be preferably used.
[0018]
In addition to the lactic acid bacterium, the protective agent of the present invention can further contain an intestinal lactic acid bacterium-proliferating oligosaccharide. Examples of the oligosaccharide include oligosaccharides that are not degraded by digestive enzymes and that are easily used by lactic acid bacteria and that promote the growth of lactic acid bacteria. More specifically, examples include galactooligosaccharides, fructooligosaccharides, and xylooligosaccharides. Or a mixture thereof or the like can be given. In the protective agent of the present invention, the blending ratio of the oligosaccharide with respect to the lactic acid bacteria can be 0 to 150 mg per 1 CFU of the total lactic acid bacteria. By containing oligosaccharides, in the small intestine, the action of neutralizing alkaline intestinal fluid and pancreatic juice is prevented by preventing the lactic acid bacteria adhering to and colonizing the intestinal wall, and in the large intestine, the growth of lactic acid bacteria is promoted to suppress harmful bacteria. .
[0019]
Although the content rate of the said lactic acid bacteria in the protective agent of this invention is not specifically limited, It can be set as the content rate suitable for administering with the preferable dosage mentioned later.
[0020]
The dosage of the protective agent of the present invention can be 10 5 CFU to 5 × 10 8 CFU as the total number of lactic acid bacteria per kg of body weight of a subject animal such as poultry per day. Further, in the case of containing a combination of homo-type lactic acid bacteria and hetero-type lactic acid bacteria as lactic acid bacteria, each can be 10 5 CFU to 10 8 CFU per kg of poultry body weight per day, and the ratio of homo-type and hetero-type is 1 It is not limited to: 1.
[0021]
Administration targets of the protective agent of the present invention are humans and animals such as poultry such as chickens. In particular, it can be preferably administered to poultry such as chickens with an egg production of 400 days or less, and humans who are reduced or fasted for cosmetic purposes.
[0022]
Although not bound by any theory, the mechanism of action by which the protective agent of the present invention prevents injury due to forced molting or dephasing / fasting is due to prevention of intestinal wall cell injury accompanying fasting and the like. It is possible. Animal intestinal fluid and pancreatic juice are alkaline, and the optimum pH of trypsin and chymotrypsin, which are typical proteolytic enzymes contained therein, is on the alkaline side. When an animal is starved, intestinal fluid and pancreatic fluid proteolytic enzymes degrade the constituent proteins of intestinal villus cells, resulting in the promotion of necrosis and detachment of intestinal wall cells. Here, by administering hetero and homo lactic acid bacteria that easily adhere to and colonize the intestinal wall of the small intestine and large intestine, the lactic acid secreted by the lactic acid bacteria attached to the intestinal wall neutralizes the alkaline properties of the intestinal juice and pancreatic juice, The mechanism of action is to prevent the degradation of intestinal wall cells by degrading enzymes, and as a result, prevent necrosis and detachment of intestinal wall cells during starvation, and thus prevent injury during food loss and fasting during forced molting. It is done.
[0023]
The forced molting method of the present invention includes a step of fasting poultry such as chicken and a step of administering the protective agent to the poultry.
[0024]
The fasting period is not particularly limited and can be appropriately adjusted so that the effect of regeneration by forced molting can be satisfactorily obtained, but can be 6 to 14 days. In addition, for fasting, it is preferable to stop feeding the feed and drink water, but it is also possible to feed non-nutritive feed. In the latter case, the protective agent of the present invention may be mixed in either drinking water or non-nutritive feed.
[0025]
The administration period of the protective agent is not particularly limited, and can be administered before the start of fasting, during the fasting period or within one or more periods after the end of fasting. It is preferred to continue administration over the period. Specifically, for example, it can be administered from 3 days before the start of fasting to 3 days after the end of fasting. Further, the dose of the protective agent can be changed before the start of fasting and during the fasting period, and the presence / absence of a component such as an oligosaccharide and the blending ratio can also be changed. The dosage of the inhibitor can be within the range of the preferred dosage of the protective agent of the present invention.
[0026]
【The invention's effect】
The forced molting injury preventive agent and the forced molting method of the present invention can perform effective forced molting without damaging poultry by administering or performing the method, and the growth of harmful bacteria in the poultry intestines. Can also be expected to improve the egg production, quality, safety, and the like.
[0027]
In addition, the starvation disorder protective agent of the present invention can effectively protect against damage due to reduced food or fasting in animals.
[0028]
【Example】
EXAMPLES Hereinafter, although this invention is demonstrated in detail with reference to an Example, this invention is not limited to these.
[0029]
Example 1 and Comparative Example 1
Feed J115-3 (made by Showa Sangyo Co., Ltd.) as feed for 60,000 chickens (chicken species: High Line Roller) in a windless poultry house with 60,000 chickens / water supply line divided into 30000 chickens. Raised. For 9 days from the day when the chicken reached 447 days of age, the chicken was fasted and forced molting was performed.
[0030]
Two days before the start of fasting, only one of the 30000 water supply lines was taken as Example 1, and Lactobacillus reuteri NHL2 strain (FERM P-19182) and Lactobacillus salivaius LH8 strain (FERM P-19181) were each supplied for 1 hour with 2 × water supply. It was fed by adding it to the drinking water at a concentration of 10 8 CFU / feather. In addition, during the 9-day fasting period, Lactobacillus reuteri NHL2 strain and Lactobacillus salivarius LH8 strain were fed by adding each to drinking water at a concentration of 3.5 × 10 5 CFU / ml. Further, on the first day after the fasting, Lactobacillus reuteri NHL2 strain and Lactobacillus salivarius LH8 strain were each fed into drinking water at a concentration of 1 × 10 8 CFU / ml with 2 hours of water supply. On the other hand, the other of the 30000 water supply lines was set as Comparative Example 1, and only water was supplied as drinking water.
[0031]
On the last day of fasting, 5 chickens of each of Example 1 and Comparative Example 1 were slaughtered, and the contents of the ileum (the contents during the fasting period suggest a large loss of gastrointestinal tissue) and bacteria Histochemistry and histochemical status of the villus at the terminal ileum were measured. The results are shown in Table 1.
