Thirteen Friesian weanling bullocks were reported stolen from a farm near Skibbereen overnight.
Farmer Martin Harte went to check on weanlings in a rented shed this Thursday morning to find a number missing.
"Whoever took them knew their stock well. Out of a group of 30 Friesians, they took the best. There were a dozen Charolais weanlings too and they were left behind," he said.
The weanlings, weighing between 250kg and 300kg, were taken since Wednesday night.
While there are a large number of Friesian weanlings in the west Cork area, Martin said: "They had their backs and tails clipped recently when I treated them for lice so that may help people notice them."
Gardai are investigating the theft.
Anyone with any information is asked to contact Skibbereen Garda Station on 028 23088.
