For a scalar nonlinear delay differential equation $\dot{N}(t) = r(t)N(t)(K-N(h(t)))/(K+s(t)N(g(t)))$ , $r(t)\geq 0$ , $K > 0$ , $h(t)\leq t$ , $g(t)\leq t$ and some generalizations of this equation, we establish explicit oscillation and nonoscillation conditions. Coefficient $r(t)$ and delays are not assumed to be continuous.
