Abstract
In this paper, we consider a class of cubic planar polynomial differential system with non-rational first integral. Using the averaging method at any order, we bound the maximum number of limit cycles which bifurcate from the periodic annulus of the origin when we perturb them inside the class of all polynomial systems of degree n.
