Butterfat And Cow Fertility At Grass - Farming Note


 

Well managed spring grass provides a high quality (typically 12 ME, 18% CP) and cost effective feed (£58/t DM) in most areas of the UK. The ‘best’ Kingshay Dairy Manager herds, (see table) when compared to the average, achieved:
• Similar yield per cow
• More milk from grazing
• Better butterfat %
• Lower concentrate use
