%X The nonlinear delay differential equation N′(t)=r(t)N(t)((K(t)-N(t-mω)K(t)+λ(t)N(t-mω)))] where m is positive integer, λ(t), K(t) and r(t) are positive periodic functions of period ω. Sufficient conditions for the oscillation, existence and global attractivity of the positive periodic solution of this  equation are obtained. Some known results are extended and improved.
