Animal deaths were reported on at least five local farms, with the heat and high humidity taking its toll on dairy herds.
It is understood at least two farms each suffered 15 or more deaths.
One farmer, who didn’t wish to be named, said the deaths were “heartbreaking”.
“You do everything you can for your animals to ensure they are as comfortable as they can be in that heat,” he said.
“Of course we do and did everything we could for them. They make us our livelihoods but they are our animals. You have a connection with them.
“This is just gutting.”
“Any loss is tragic,” another said, “let alone in these circumstances.”
Another farmer reported to have lost three per cent of his milking herd.
“Friday and Saturday were both extremely hot but Thursday was probably the worst day with the humidity,” he said.
“Saturday was bad as well and the humidity was high.
“Saturday reached 40 degrees but the humidity was 50 per cent. A nearby property topped 45 degrees.
“Friday was a dry heat - the cows can handle the heat but that, combined with the humidity, really knocks them around.”
Despite receiving 17.4 millimetres of rain on Thursday the warm weather rolled in.
