We show that the production rates of light-flavoured mesons and baryons in inelastic pp and p$\bar{ p}$ collisions can be described by a simple approach used to describe data obtained in $e^{ +}e^{ -}$ annihilation. Based on the idea of string fragmentation, the approach describes the production rates of light-flavoured mesons and baryons originating from fragmentation in terms of the spin, the binding energy of the particle, and a strangeness suppression factor. Apart from a normalization factor and the additional sea quark contribution in inelastic pp and p$\bar{ p}$ collisions, pp, p$\bar{ p}$ and $e^{ +}e^{ -}$ data at various centre-of-mass energies are described simultaneously.
