AHDB updates its standard litre

Published 8 June 18

AHDB has updated the standard litre used in our milk price calculator and league table, to reflect the changes in milk production in recent years. The new standard litre is based on average UK production in the 3 years to 2017/18, while the previous one went up to 2015/16.

Butterfat and protein levels have been increasing in recent times and the new values are 0.04 and 0.03 percentage points higher respectively, with slight improvements to SCC and bactoscan levels. It has also been decided keep all four constituents (butterfat, protein, SCC and bactoscan) fixed through the year for easier comparison. The only variable changing each month will be the volume, which reflects the seasonality of milk production.

These changes were implemented for the April 2018 League Table. While the impact on contracts will vary depending on payment rates, in general the higher fat and protein levels lead to a slight increase in prices from March to April of around 0.2ppl.
