We show that any system of ODEs can be modified whilst preserving its homogeneous Darboux polynomials. We employ the result to generalise a hierarchy of integrable Lotka-Volterra systems.

Keywords: Darboux polynomials, Lotka-Volterra systems, Liouville integrability, superintegrability, ordinary differential equations.
