【発明の属する技術分野】
本発明は、主として家禽用飼料に添加して用いる家禽卵性質改善剤に関し、詳しくは、卵白の濃厚卵白部分の粘りが高くなり、卵白の起泡性が高く、生成した気泡の保持力が高く、泡戻りの少ない鶏卵等の家禽卵を得ることのできる、しかも卵黄部分の重量が重く、その盛り上がりが長期間保持され、卵重量の減少の少ない家禽卵を得ることのできる家禽卵性質改善剤に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
家禽卵は、全卵のまま或いは卵黄と卵白とに分離して多種の加工食品の原料として広く利用されている。
【0003】
卵白は、菓子類、パン類、食肉及び水産練成品を始めとする加工食品の原料とされ、これら加工食品の製造において、該卵白の起泡力が利用されている。起泡力は卵白の重要な機能の一つであって、生成した泡のボリュームが単に大きいだけでなく、その泡が丈夫であり、加工する際、気泡の保持力が大であることが求められている。
【0004】
そこで、様々な手段によって卵白の起泡性を高める方法が提案されている。例えば、加工食品に使用する卵白を長期保持するために、卵白を乾燥する手法が用いられている。この際、殺菌を兼ねてエージングすることによって、卵白の起泡性を強化することが知られている。
【0005】
また、ポリフェノール等の添加により卵白の起泡性を向上させること(特開平8−266230号公報)が提案されている。しかし、ポリフェノールを飼料へ添加した場合、卵白の透明度及び起泡力を高める効果は認められるが、気泡の保持力の向上までには至っていない。
【0006】
ところで、鶏卵では、飼料中の物質の一部又は全部が、細胞たる卵黄に移行する現象が知られており、これを利用した様々な技術が提案されている。しかしながら、卵白への物質の移行は未だ明確に把握されておらず、生細胞としての卵黄への物質の移行と、細胞ではない卵白への物質の移行とを、同列に考えることはできない。
【0007】
また、界面活性剤と抗生物質とを同時に家禽に摂取させると、高価な抗生物質の薬効が向上することが知られている(例えば、特開昭57−177654号公報及び特開昭57−165322号公報)ものの、界面活性剤の摂取が産卵される卵の特性に直接的に与える影響については何ら検証されていない。
【0008】
従って、本発明の目的は、エージング等の必要がなく、産卵直後でも卵白の起泡性が高く、生成した気泡の保持力が高く、泡戻りが少なく、且つ卵黄部分の重量が重く、その盛り上がりが長期間保持され、卵重量の減少の少ない家禽卵を得ることができる家禽卵性質改善剤を提供することにある。
【0009】
【課題を解決するための手段】
本発明者らは、鋭意検討した結果、家禽に界面活性剤を与えた場合、界面活性剤が卵中に単純に移行するのではなく、移行したとしても微量であり、量を定量することはできないが、卵白の特性が界面活性剤を添加しない場合に比べて著しく向上することを知見した。即ち、界面活性剤を含有する飼料で生育させた家禽が生む卵は、起泡性が高く、更に気泡の保持力が極めて高く、泡戻りが非常に少ないこと知見した。
更に本発明者らは、界面活性剤を含有する飼料で生育させた家禽が産む卵は、卵自体の重量も重くなり、卵黄の重量が重く、しかも卵黄の盛り上がりは長期間保存しても保持され、卵重量の減少の少ないことを知見した。
【0010】
本発明は、上記知見に基づきなされたもので、家禽卵の卵白の起泡性、生成した気泡の保持力、卵黄の割合及び保存中の卵重量の減少を改善するための家禽卵性質改善剤であって、ソルビタン脂肪酸エステル、ポリグリセリン脂肪酸エステル及びプロピレングリコール脂肪酸エステルからなる群から選択される1種又は2種以上の界面活性剤を、界面活性剤純分として75〜100重量%含有してなる家禽卵性質改善剤を提供するものである。

BACKGROUND OF THE INVENTION
The present invention relates to a poultry egg property improving agent that is mainly used by adding to poultry feeds. Specifically, the thick egg white portion of egg white is highly viscous, the egg white foaming property is high, and the generated air bubbles are highly retained. A poultry egg property improving agent that can obtain poultry eggs such as chicken eggs with little foam return, and can obtain poultry eggs whose egg yolk portion is heavy, whose bulge is maintained for a long period of time, and whose egg weight is less reduced. About.
[0002]
[Prior art and problems to be solved by the invention]
Poultry eggs are widely used as raw materials for various processed foods as whole eggs or separated into egg yolk and egg white.
[0003]
Egg white is used as a raw material for processed foods such as confectionery, breads, meat and marine products, and the foaming power of the egg white is used in the production of these processed foods. Foaming power is one of the important functions of egg white. Not only is the generated foam volume high, but the foam is strong, and when processing, it needs to have a large air bubble retention. It has been.
[0004]
Therefore, methods for enhancing the foaming property of egg white by various means have been proposed. For example, in order to maintain the egg white used for processed food for a long period of time, a technique of drying the egg white is used. At this time, it is known to enhance the foaming property of egg white by aging also for sterilization.
[0005]
In addition, it has been proposed to improve the foaming property of egg white by adding polyphenol or the like (JP-A-8-266230). However, when polyphenol is added to the feed, the effect of increasing the transparency and foaming power of egg white is recognized, but the retention of bubbles has not been improved.
[0006]
By the way, in chicken eggs, it is known that a part or all of the substances in the feed are transferred to egg yolk, which is a cell, and various techniques using this have been proposed. However, the substance transfer to egg white has not been clearly grasped yet, and the substance transfer to egg yolk as a living cell and the substance transfer to egg white which is not a cell cannot be considered in the same line.
[0007]
Further, it is known that when a surfactant and an antibiotic are taken into poultry at the same time, the medicinal effect of an expensive antibiotic is improved (for example, JP-A-57-177654 and JP-A-57-165322). However, it has not been verified at all about the effect of the intake of surfactant on the characteristics of eggs laid.
[0008]
Therefore, the object of the present invention is that there is no need for aging, etc., egg white is highly foamable immediately after egg laying, the retention of generated bubbles is high, there is little foam return, and the weight of the egg yolk is heavy, and its rise Is to provide a poultry egg property improving agent capable of obtaining a poultry egg that is maintained for a long period of time and has a small decrease in egg weight.
[0009]
[Means for Solving the Problems]
As a result of intensive studies, the present inventors, when a surfactant was given to poultry, did not simply transfer the surfactant into the egg, but even if it was transferred, the amount of the surfactant was not determined. However, it has been found that the characteristics of egg white are remarkably improved as compared with the case where no surfactant is added. That is, it was found that eggs produced by poultry grown on a feed containing a surfactant have high foaming properties, extremely high air bubble retention, and very little foam return.
Furthermore, the present inventors have found that eggs produced by poultry grown on a feed containing a surfactant also have a heavy egg weight, a heavy egg yolk weight, and the egg yolk rise is preserved even when stored for a long period of time. And found that there was little decrease in egg weight.
[0010]
The present invention has been made on the basis of the above-mentioned findings, and a poultry egg property improving agent for improving the foamability of egg white of poultry eggs, the retention of generated bubbles, the ratio of egg yolk and the weight of eggs during storage. And containing one or more surfactants selected from the group consisting of sorbitan fatty acid ester, polyglycerin fatty acid ester and propylene glycol fatty acid ester , 75-100% by weight as a pure surfactant. A poultry egg property improving agent is provided.
[0011]

Although it does not specifically limit as a method of oral administration, It selects suitably according to the state (pellet, powder, liquid, etc.) of a poultry egg property improving agent. When the poultry egg property improving agent is a solid, it can be cut into small pieces and mixed and administered so as to be uniform in the feed. Moreover, when a poultry egg property improving agent melt | dissolves in water, you may add and administer it in water. Moreover, when a poultry egg property improving agent melt | dissolves in fats and oils, you may melt | dissolve in fats and oils and add to feed, or you may melt | dissolve in fats and oils and coat feed. Further, the poultry egg property improving agent may be orally administered as it is, but in order to ingest the necessary amount, it is better to add it to the feed or water and ingest with the feed or water. In addition, administration by intravenous injection or abdominal vaginal injection may be used, but such an administration method is not practical.
[0017]
The dose of poultry egg property improving agent of the present invention to poultry varies depending on the type and size of poultry and other breeding conditions, but the surfactant is pure with respect to the feed or water given daily for laying poultry. An amount of 0.05 to 5% by weight is preferred.
[0018]
As the feed used when blending the poultry egg property improving agent of the present invention into the feed, commonly used feeds can be used, for example, grains such as corn, wheat, barley, rye, milo, rice bran , Bran such as bran, wheat bran, soy bean cake, corn gluten meal, molasses Examples include blends.
