  We investigate the relic abundance of asymmetric Dark Matter where the
asymmetric Dark Matter is non--thermally produced from the decay of heavier
particles in addition to the usual thermal production. We discuss the relic
density of asymmetric Dark Matter including the decay of heavy particles in low
temperature scenario. Here we still assume the universe is radiation dominated
and there is asymmetry before the decay of heavy particles. We obtained
increased abundances of asymmetric Dark Matter when there is additional
contribution from the decay of heavier particles. Finally we find the
constraints on the asymmetry factor and annihilation cross section using the
Planck data.
