Summary: By means of Riccati transformation technique, we establish some new oscillation criteria for the second-order nonlinear delay dynamic equations $$\bigl(p(t)\bigl(x^{\Delta}(t)\bigr)^{\gamma}\bigr)^{\Delta}+q(t)f\bigl(x\bigl(\tau(t)\bigr)\bigr)=0$$ on a time scale $\mathbb{T}$, here $\gamma \geq 1$ is a quotient of odd positive integers with $p$ and $q$ real-valued positive rd-continuous functions defined on $\mathbb{T}$. Our results improve and extend some results established by {\it S. H. Saker} [J. Comput. Appl. Math. 177, No.~2, 375--387 (2005; Zbl 1082.34032)] but also unify the oscillation of the second order nonlinear delay differential equation and the second order nonlinear delay difference equation.
