Federated Farmers is re-opening its feed line phone service for Southland and South Otago farmers.
It's responding to concerns that some farmers there could run short of feed after an abnormally dry summer in the south.
Federated Farmers adverse events spokesman David Rose says a lack of rain over December and early January means winter feed crops in Southland and southern and coastal Otago have lost up to two growing months.
Winter feed crops such as turnips are essential in southern New Zealand because grass growth stops for several months over the winter.
Mr Rose says sourcing feed for the winter should not be too difficult because there have been good growing conditions further north.
The feed information service helps to connect those with feed to spare with those who are short.
The line opens on Monday, and the number for farmers to call is 0800 376 8448.
