Judging the oscillation and asymptotic behavior of delay dynamic equations on time scale plays an important role in mathematical physics, automatic control theory and engineering, infectious disease model analysis, bridge design and so on. Thus, the oscillation behavior of third-order nonlinear Emden-Fowler type delay dynamic equation with a sublinear neutral term on time scales are investigated. By using the dynamic calculus on time scales, generalized Riccati transformation and inequality technique, two oscillation theorems to ensure that every solution of the equation oscillates or converges to zero are obtained. These results extend and improve the results established in previous literatures. Finally, the effectiveness of the theoretical results obtained here are illustrated with two examples.
