It would be nice if other costs of breeding could be covered by the scheme but service fees are likely to be the only administratively viable and auditable way.

A levy on the foals produced by a stallion over a set number could be a way of providing funding but may result in stallion owners increasing the fee to make the same or more money from a lessor number of mares to get round it. The major studs/stallion owners have also in many cases become major sponsors so increasing their costs could be counterproductive if it comes out of sponsorship budgets.
