If foal numbers are down then doesn't that mean demand is down? If the demand was there the foals would be being purchased. Another point saying demand is down is that even with lower foal numbers breeders are still complaining of low sale prices. So if MORE foals are born under this initiative then breeders will lose out more as supply will outweight demand too heavily and sale prices will go down. Either the industry and overpopulated or consumer demand needs to increase.
They are trying to increase consumer demand of Aust foals by taxing imports. Yes this will work. But the side affects are not worth it (a stagnant breed, a fishbowl)
The other way to increase demand is create a better product. This will create a better breed of horse. Side affects will be increase costs for breeders.
Another alternative is for breeders to accept lower prices. But this means breeders lose out on sales and the breed is stagnant.
So my conclusion is the breeding industry is either over-populated or a dying industry. You don't see the pie shop getting taxed by the sausage roll shop just because the pie shop is more popular. Breed to race; and as I said earlier; if field numbers go down then there will always be owners importing in and trying to take advantage of easier competition.
