When we look internationally at reduction efforts that have taken place, we see that a lot of alternative strategies have been put in place, whether they be management or other. Certainly vaccine alternatives and feed alternatives are part of that. It's a large tool.
Really, what we're looking at is maintaining the health of the gut of the chicken from day one all the way through and making sure we don't have disease incursions. That's really where these probiotic and prebiotic acids come into play that other countries have had some success with. It's different from farm to farm, and certainly one of the reasons we have an implementation period is to figure out exactly what works.
Quite frankly, I think one of reasons we've gone with the implementation period we have is to hopefully have access to those products. The industry has certainly gone out on a limb in terms of putting forward the reduction strategy that has been agreed upon, but part and parcel of that is having the products available in order to move forward. That's why it's such a crucial area, but it has a time significance to it now in order to meet our objectives.
