Estimating the term…
The present invention relates to a pelletization-resistant rumen bypass formulation of a feed additive resistant to pelletization by applying a reinforcement measure resisting to a mechanical stress during the pelletization and humidification and heating at steaming, etc. to a rumen bypass formulation formed of biologically active principles and protective matrices and a feed pellet for ruminants containing said pelletization-resistant rumen bypass formulation therein. More particularly, the present invention relates to a pelletization-resistant rumen bypass formulation prepared by including one or more rumen bypass formulations formed of biologically active principles and protective matrices in the moldings of various types of macromolecules described above (pelletization-resistant protective matrices) having a shape retaining property during a process of pelletization, and a feed pellet for ruminants applying the same. The present invention enabled the practical use of feed pellets containing the rumen bypass formulation which was not practically possible to formulate in the past.
A feed additive composition suitable for use in a feed pellet comprising a rumen bypass formulation formed from a biologically active ingredient and a protective matrix and further comprising a pelletization protective matrix selected from the group consisting of natural macromolecules, denatured natural macromolecules and synthetic macromolecules and wherein said macromolecules have a modulus of elasticity from between 10.sup.8 to 10.sup.11 dyne/cm.sup.2 at a temperature of 30.degree. C. and a glass transition point of from between 50.degree. to 150.degree. C. by a dynamic viscoelasticity measurement.
