In this paper we offer criteria for property (B) and additional asymptotic behavior of solutions of the $n$ -th order delay differential equations ${(r (t) {[x^{(n - 1)} (t)]}^{γ})}^{'} = q (t) f (x (τ (t))) .$ Obtained results essentially use new comparison theorems, that permit to reduce the problem of the oscillation of the n-th order equation to the the oscillation of a set of certain the first order equations. So that established comparison principles essentially simplify the examination of studied equations. Both cases $\int^{\infty} r^{- 1 / γ} (t) t = \infty$ and $\int^{\infty} r^{- 1 / γ} (t) t < \infty$ are discussed. ...
