It is low, the zinc of level is contained and the protein characteristic fodder substance and its production method bypass potential of the rumen being high

摘要

Vegetable meal compositions having high-rumen bypass potentials for use in the feeding of ruminant animals, and a method for producing the compositions are claimed. The claimed compositions comprise a protein meal and low levels of zinc ions, with the zinc ions being present in an amount sufficient to provide about 0.003-0.008 parts zinc ions per part of protein in the meal. The composition has a rumen bypass potential, as measured by the "Percent of Total Protein that is Available and Undegraded", or "% AUN", of not less than about 30. The method for producing the composition comprises treating the meals with low levels of zinc ions and heating the mixture under moist heat conditions.
