(Reuters) - Britain's Dairy Crest Group Plc (DCG.L) said higher costs would reduce profit in its milk business in the current year, sending its shares down as much as 8 percent.
Dairy Crest did not release details about how far profit might fall in the dairies division, which makes up about 70 percent of its total revenue, or give a forecast for the overall company.
Higher milk costs added 40 million pounds to raw material costs in the dairy operations in the year ended March 31 at the company, whose brands include Country Life, Clover and flavoured milk drink Frijj.
"The key question is the outlook and the comments have been around a tougher year ... because of the more aggressive price competition from retailers and basically high input prices," analyst Charles Hall of Peel Hunt told Reuters.
Dairy Crest said residential sales fell 10 percent in the year as more people bought milk from shops rather than buying Dairy Crest milk from their local milkman.
The company said revenue from the dairies business declined 1 percent in the year, while its spreads business reported a decline of 9 percent.
Panmure Gordon analysts cut their target price on the stock to 470 pence from 550 pence, citing concerns over weak performances in both the spreads and dairies businesses.
