The aim of this paper is to present sufficient conditions for all bounded solutions of the second order neutral differential equation to be oscillatory and to improve some existing results. The main results are based on the comparison principles.

In this paper we present some new oscillatory criteria for the -th order neutral differential equations of the form The results obtained extend and improve a number of existing criteria.
