  Recent measurements of the proton to pion ratio at $\sqrt{s}_{NN}=2.7$ TeV by
the ALICE collaboration at the LHC have found it to be lower than predictions
from thermal fits. In this paper we investigate the role that the extended mass
spectrum via Hagedorn states- massive resonances that follow an exponential
mass spectrum and possess large decay widths- play in the determination of
particle ratios at LHC through a scenario of multi-particle reactions and
dynamical chemical equilibrium within the hadron gas phase. We show that it is
possible to describe the lower $p/\pi$ ratio at LHC while still obtaining the
experimental ratio of $K/\pi$ and $\Lambda/\pi^+$ in the Hagedorn state
scenario if the protons are underpopulated at the switching temperature from
hydrodynamics to the hadron gas phase.
