The largest dairy farms in Great Britain are expanding faster than those at the other end of the scale, according to the Milk Development Council.
Individuals who held over three million litres of quota at the end of the 2004/05 quota year increased their quota holding by an average of 45.5% compared with just two years previously.
At the end of the 2004/2005 quota year, 175 individuals were registered as holding more than three million litres of quota. Almost 7,000 individuals held less than half a million litres each. The average rise in quota holding in this group was 3.9%.
The MDC says larger quota holders are likely to be receiving higher milk prices due to volume bonuses and are also likely to have lower costs.
