National average milkfat (MF) production

176 kg per cow per year (for the period 2004-2005)

Typical yields of milk

Jersey 2,900 litres of milk at av fat test of 5.8%

Fresian 4,100 litres at av fat test of 4.4%

Rule of thumb for estimating seasonal dairy production

(predominantly Jersey herds)

Multiplying total peak daily milk production in litres by 10 will give approximate total kg of milkfat to be expected in a normal season.
