Dairy farmers keen to improve their milk production, are being urged to identify the stress levels of their cows.
Cow behaviour expert Darold Klindworth says when a cow is stressed, her milk output falls, milking times are slower and health costs can rise.
He'll be leading a workshop on the subject at next week's Farmers' Forum at Mystery Creek.
He says many cows don't show outward signs of stress, so getting to know your cow is essential.
Mr Klindworth says sudden noises or movements from farmers can often be enough to agitate cows and make them flighty and nervous.
