Abstract: The moments and absolute continuity of measure-valued branching Brownian motions with bounded interacting intensity are investigated. An estimate of higher order moments is obtained. The absolute continuity is verified in the one dimension case. This thereby verifies the conjecture of M\'{e}l\'{e}ard and Roelly in [5].

Interacting measure-valued branching process, Absolute continuity, Branching Brownian motion, Comparison lemma.
