Ability of green sulfur bacteria Mouth Protection Chlorobium limicola Ya-2002 to assimilate various nitrogen sources was investigated.It was shown that Chlorobium utilize nitrogen of ammonium, amino group and fixes molecular nitrogen.Nitrogen of ammonium was found to be the most suitable for these bacteria.Addition of several amino acids of L-confo

Forages dry matter (DM) could vary among batches and in particular when silages are fed.These variations could modify nutrients composition of total mixed ration and affect cows performance.The aim of this study was to evaluate the effect of application of a precision feeding system (PFS) based on a near infra-red scanner, on metabolic conditions a
