Even with when this invention 40 weight % of basic amino acid which is the biological active material above 65 weight % under being the fodder addition composition and its production method for the ruminantia animal of the distributed which contains, has lumen bypass characteristic, at the same time with the small intestine of the ruminantia animal discharges the said biological active material at high density and can urge the milk yield production of the lactation cow, to fodder adds development of the production method where efficiently it continues produces the granule and the said granule which can make the optional form which the classification it is difficult to do is offered. As for this invention, fusion point to be higher than the 50 at least the protective agent of 1 where it is chosen from the hardening vegetable oil or the hardening animal oil which is lower than the 90 kinds, the lecithin 0.05 or 6 weight %, 40 weight % of water and basic amino acid above 65 weight % under the fodder addition composition, and the fusion point which for the ruminantia animal are contained to be higher than the 50 at least the protective agent of 1 where it is chosen from the hardening vegetable oil or the hardening animal oil which is lower than the 90 kinds, soaks the melted blend which consists of the lecithin and basic amino acid in underwater and regards the production method of the fodder addition composition for the ruminantia animal which features that it solidifies.本発明は、生物学的活性物質である塩基性アミノ酸を40重量%以上65重量%未満含有する分散型の反芻動物用飼料添加組成物及びその製造方法であって、ルーメンバイパス性を有し、かつ反芻動物の小腸で該生物学的活性物質を高濃度で放出して泌乳牛の乳量生産を促すことができ、飼料に添加した場合でも分級し難い任意の形状とすることができる顆粒と、該顆粒を効率よく連続生産する製造方法の開発を提供する。 本発明は、融点が50℃より高く90℃より低い硬化植物油または硬化動物油から選ばれる少なくとも1種の保護剤、レシチンを0.05乃至6重量%、水及び塩基性アミノ酸を40重量%以上65重量%未満含有する反芻動物用飼料添加組成物、及び、融点が50℃より高く90℃より低い硬化植物油または硬化動物油から選ばれる少なくとも1種の保護剤、レシチン及び塩基性アミノ酸よりなる溶融混合物を水中に浸漬し固化することを特徴とする反芻動物用飼料添加組成物の製造方法に関する。
