The paper is devoted to a class of cubic Kolmogorov systems, where at most six small amplitude limit cycles can bifurcate from singular point in the first quadrant. The Reduce and Maple computer systems were used for the calculation of the focal values. There are also some conclusions about the number of invariant lines.
