Abstract

In a balance trial, 2 cows were fed on hay containing nitrate, proline and N-nitrosoproline (NPRO). No in vivo formation of NPRO was found. NPRO in hay was recovered from the urine and the faeces. Nitrite and proline were metabolized for the greater part in the rumen fluid. So, it was estimated that 10 and 20%, respectively, will enter the abomasum. In spite of a favourable pH in the abomasum no formation of NPRO was found. (Abstract retrieved from CAB Abstracts by CABI’s permission)
