Abstract
Description
一方で、生理活性をもつ物質を経口投与しても、第一胃で微生物群に消化されてしまうため、反芻動物に対してその生理活性を発揮させることは困難であった。そこで、反芻動物のルーメンにおいて生物学的活性物質を安定的に保護し、ルーメン通過後の第四胃以降に生物学的活性物質を溶出させて消化管に吸収させる飼料添加組成物が開発されてきた。
即ち、本発明は以下の通りである。
[2]生物学的活性物質の20℃の水100gに対する溶解度が、0.01g以上且つ20g以下である、[1]記載の製造方法。
[3]反芻動物用飼料添加組成物における生物学的活性物質の含有量が、0.5重量%以上且つ70重量%以下である、[1]又は[2]記載の製造方法。
[4]反芻動物用飼料添加組成物におけるレシチンの含有量が、0.05重量%以上且つ6重量%以下である、[1]~[3]のいずれか一つに記載の製造方法。

[13]前記水中造粒物が、水中造粒物の粉砕物である、[8]~[12]のいずれか一つに記載の組成物。
以下において、反芻動物用飼料添加組成物のルーメンにおける保護性を、単に「保護性」と称し、反芻動物用飼料添加組成物の下部消化管における溶出性を、単に「溶出性」と称する場合がある。
本発明において「反芻動物用飼料添加組成物」とは、通常、反芻動物用飼料に添加されて、反芻動物が当該飼料を摂取する際にあわせて摂取される組成物をいう。ただし、反芻動物に摂取されさえすれば必ずしも飼料に添加されなくてもよく、例えば、本発明の組成物は単独で反芻動物に摂取され得る。
成分Aとして用いられる硬化植物油及び硬化動物油は、常温(25℃)で液状の植物油又は動物油に水素を添加して固化させたものであり、極度硬化油も包含する概念である。本発明において用いられる硬化植物油及び硬化動物油の融点は、通常50℃より高く、ルーメンでの保護性が向上し得ることから、好ましくは55℃以上であり、より好ましくは60℃以上である。また、当該融点は、通常90℃より低く、溶出性が向上し得ることから、好ましくは80℃以下であり、より好ましくは70℃以下である。
成分Bとして用いられるレシチンは、界面活性剤として作用し、生物学的活性物質の表面を改質して、当該活性物質を溶融された保護剤中で偏在させずに均一分散させると考えられる。
成分Cとして用いられる生物学的活性物質とは、反芻動物に摂取されたときに、その生体内において生理活性機能を示すことができる物質をいい、例えば、アミノ酸及びその塩、ビタミン、酵素、タンパク、ペプチド、脂肪酸、核酸、ステロイド等が挙げられる。
具体的には、成分Cの20℃の水100gに対する溶解度は、好ましくは0.001g以上であり、より好ましくは0.005g以上であり、特に好ましくは0.01g以上である。また当該溶解度は、好ましくは60g以下であり、より好ましくは20g以下である。
具体的には、本発明の組成物の粒径は、0.5mm以上且つ2mm以下である。
また、粒径の調整法は特に制限されないが、例えば溶融混合物を貯留する容器の孔を小さくする方法や、上記好ましい粒径以上の組成物を粉砕及び篩分する方法がある。
本発明の組成物の粒径は、日本工業規格のJIS Z 8801にて規定される標準篩によって篩分することで規定される。
成分A~Cを含有する溶融混合物を水中で造粒して得られた造粒物(即ち、水中造粒物)の粒径が、もとから上記の特定の範囲内であれば、当該造粒物をそのまま本発明の組成物として用いてよい。
本発明の組成物における成分Bの含有量は、通常0.05重量%以上であり、ルーメンでの保護性が向上し得ることから、好ましくは0.5重量%以上であり、より好ましくは1重量%以上である。また当該含有量は、通常6重量%以下であり、ルーメンでの保護性が向上し得ることから、好ましくは5重量%以下であり、より好ましくは3重量%以下であり、特に好ましくは2重量%以下である。
本発明の組成物における成分Cの含有量は、通常40重量%以上であり、組成物中に高濃度で含有させ得ることから、好ましくは45重量%以上であり、より好ましくは50重量%以上である。また当該含有量は、通常70重量%以下である。
溶出試験器(富山産業社製)を用い、反芻動物(例、乳牛等)の体温に相当する温度(例、39℃)に加温した超純水(Milli Q(ミリポア社製)を使用して製造)900mlに製剤サンプル約3gを入れ100rpmで撹拌し、撹拌開始から20時間後に、撹拌中の試験液から保護率測定用に2mlを採取し、生物学的活性物質の濃度を測定する(濃度A、単位:mg/dl)。
<溶出率算出のための生物学的活性物質の濃度(濃度B)の測定>
上記保護率測定用サンプルを採取した直後の試験液に、100rpmで撹拌を続けながら、胆汁末(和光純薬社製)とパンクレアチン(和光純薬社製)の水溶液(胆汁末及びパンクレアチンの濃度は、いずれも23.4g/100ml)8mlを添加して小腸相当試験液とし、当該水溶液の添加から5時間後に、撹拌中の試験液から溶出率測定用に2mlを採取し、生物学的活性物質の濃度を測定する(濃度B、単位:mg/dl)。
上記生物学的活性物質の濃度(濃度A及びB)は、液体クロマトグラフィー(ウォータース社製)により測定する。但し、生物学的活性物質がリジンである場合は、バイオセンサー(王子計測機器社製)を用いて測定する。
<生物学的活性物質の保護率および溶出率の算出>
生物学的活性物質の保護率および溶出率は次の式により算出する。
保護率[%]={1-(濃度A[mg/dl]×9)/(製剤サンプル重量[g]×1000×製剤サンプル中の生物学的活性物質の含有量[重量%]/100)}×100
溶出率[%]={((濃度B[mg/dl]-濃度A[mg/dl])×9)/(製剤サンプル重量[g]×1000×製剤サンプル中の生物学的活性物質の含有量[重量%]/100)}×100
また、例えば、生物学的活性物質の水への溶解度が低い場合、すなわち20℃の水100gに対する溶解度が0.001g以上且つ60g以下である場合、本発明の組成物及びこれと組成が同様で且つ粒径が2mmを超える飼料組成物の生物学的活性物質の溶出率を比較すると、後者は溶出率が0%の場合もありうるが、粒径が0.5以上且つ2mm以下である前者は、粒径が2mmを超える後者に比べて溶出率が高い。一方、生物学的活性物質の水への溶解度が高い場合、粒径が小さくなるほど生物学的活性物質の溶出率が高くなるとは限らず、むしろ溶出率が低くなることすらある。
