  Giovannini's parton branching equation is integrated numerically using the
4th-order Runge-Kutta method. Using a simple hadronisation model, a
charged-hadron multiplicity distribution is obtained. This model is then fitted
to various experimental data up to the TeV scale to study how the Giovannini
parameters vary with collision energy and type. The model is able to describe
hadronic collisions up to the TeV scale and reveals the emergence of gluonic
activity as the centre-of-mass energy increases. A prediction is made for
$\sqrt{s}$ = 14 TeV.
