This is my follow up question and Mr. Murphy might not have the information to hand but if we were to look at the average feed cost per annum, and if you were to add these additives, what percentage increase is there for the feed per annum? Does it increase the cost by 5% per annum or does Mr. Murphy have a rough idea of how much it increases the cost to a farmer? I know it depends on livestock numbers, etc., but is there an indication of the cost in that regard?
