New Zealanders turn their clocks forward an hour tonight as daylight savings begins.
Southland Federated Farmers president Geoffrey Young said cows had a tough time adjusting.
"I think dairy farmers have to go through a bit of a transition with their cows.
"But for the likes of shearers and hill and high country people out mustering, it's no problem for them. In fact, it's preferable to have that daylight saving."
The European Union Commission is proposing to end daylight saving, after public consultation found 84 percent of respondents wanted permanent year round time.
However, a spokesperson for Internal Affairs Minister Tracey Martin said she was not interested in commenting on whether New Zealand could follow suit.
Daylight saving time will continue until April 7, 2019, when everyone gets an extra hour's sleep.
