Abstract
Discrete periodic n-species food-chain systems with Holling types II and III functional responses and time delays are investigated, respectively. By using Gaines and Mawhin's continuation theorem of coincidence degree theory sufficient conditions are obtained for the existence of positive periodic solutions of the systems.
