We present new oscillation criteria for the second order nonlinear neutral delay differential equation where t ≥ t0, τ, and α are positive constants and the functions p, q, a, σ ∈ C ([t0, ∞], ℝ). Our results generalize and improve some known results for oscillation of second order neutral delay differential equations. Our results are illustrated with an example.
