Investment in facilities has been credited with helping Robert Wiseman Dairies to record volume growth.

Milk volumes for the year to 3 April were up 11% on a like-for-like basis, the company said in a trading update this week. Turnover was "above forecasts".

Increased capacity at its Bridgwater dairy had allowed for higher volume growth, Wiseman said, with work to boost capacity to 500 million litres set to be completed by October.

Profits were aided by high bulk cream prices, but these had stabilised since the peak of October 2009 and were unlikely to bring another cash windfall in the year ahead. Rising oil, diesel and HDPE costs could also hit profitability over the coming year, Wiseman warned.

"Looking forward to next year, we are in good shape, with volumes growing, a sound balance sheet, low gearing and state-of-the-art facilities," said group finance director Billy Keane.
