Absorption of acetate-1-C14 from the reticulo-rumen of Calves 3 to 4 days old

摘要

Abstract The ability of calves to absorb and metabolise steam volatile fatty acids (VFA) was investigated by the introduction of acetate–l–C14 into the rumen of three anaesthetised animals 3 to 4 days old. Acetate–l–C14 appearance in rumen effluent blood and clearance from peripheral blood were considered sufficient evidence of assimilation and utilisation respectively. All the calves absorbed and rapidly metabolised the isotope.
