Mr. Bill Callanan:

We are happy to send the committee the material concerning how the calculations are done. It must be an open and transparent process. If we consider this aspect, it is a factor of the volume of slurry produced as well. If the volume increases, then, in the context of those figures, the nitrogen as a percentage of that reduces as well. Overall, however, the 89 kg, the 106 kg, etc. is all calculated annually based on what the animals eat and the nitrogen content of that material. A factor is also taken out for maintenance in this respect, and this then generates an excretion factor as well. There is a formula concerning how this value is calculated and, as I understand the situation, this is a Europe-wide approach. Therefore, if we consider our typical bands now, and we take the existing 106 kg level, there are many production systems that are much higher. I do not have the figures in this regard, but we can get them for Dutch cows. I think the level is 120 kg or something like that for the nitrogen figure in the Netherlands, which is proportionate to its production, which is way over 6,500 l. I think that was the figure given by the ICMSA, but it could be 8,000 l or 10,000 l.
