Visited a Holstein dairy herd in County Wicklow which presented me with a herd of cows producing in excess of 10,000 litres in a 305 yield. This production system suits where winters in this part of Ireland are at least 6 months. The base farm is relatively small so feed has to be harvested on outside farms and brought back to the home farm for feeding the animals. The argument that one should focus on grass based milk productions will not work in this part of Ireland. Drawing up these systems, one has to bear in mind farm fragmentation, soil types, farm labour and the skill of the farm labour involved.
