In this paper, we show an inequality between the degrees of the conductor and of the Hodge line bundle of a hyperelliptic curve over a discrete valuation ring. For that we show a result about the lifting of p-cyclic covers of the projective line. We then apply this result to get information about the boundary of the moduli space of hyperelliptic stable curves and show the inequality.
