The livestock market in Leeuwarden is introducing a new weight class for animals heavier than 60 kilos, following a change in breeding practices that has resulted in heavier calves. Currently, the market's heaviest category is 50 kilos and above. The new classification is expected to better value the heavier calves. However, Vee&Logistiek Nederland, which processes dairy cattle, has announced it will not create an additional class for calves over 60 kilos and instead focuses on quality classes rather than weight.
