The cross-breeds will be stockier and beefier than pure Jerseys
Black cows will soon be seen grazing in Jersey's fields.
Three calves were born last week to Jersey cows impregnated with imported Aberdeen Angus bull semen.
It is an experiment by the Royal Jersey Agricultural and Horticultural Society to see if there is a market for locally reared beef.
"The cows will be jet black, so it will be easy to see they are not pure Jersey cows," said David Hambrook the society's spokesperson.
He said four or five local farmers have also used the Aberdeen Angus semen, so more cross-bred calves could soon be born.
The calves are stockier and beefier than pure Jerseys and have been bred intentionally for meat.
Mr Hambrook said it would be between 15 months and two years before the cows are ready for slaughter.
