By using Mawhin’s continuation theorem of coincidence degree theory and some skills of inequalities, we establish the existence of at least periodic solutions for a kind of -species Lotka-Volterra food-chain system with delays and impulses on time scales. One example is given to illustrate the effectiveness of our results.
