It might be orders of magnitudes larger than the observed baryon asymmetry $b\\simeq {\\cal O}(10^{-10})$, $|l|/b \\leq {\\cal O}(10^{9})$. We found that the dynamics of the cosmic QCD transition changes for large asymmetries. Predictions for asymmetries in a single flavour $l_f$ allow even larger values. We find that asymmetries of $l_f\\leq {\\cal O}(1)$ in a single or two flavours change the relic abundance of WIMPs.
