Livestock Improvement's general manager of genetics, Peter Gatley, says the company has developed a new ranking index especially for once-a-day milking.
Breeders have taken performance data from 300 herds being milked once a day, instead of the traditional twice-a-day milkings, to select genetics suited to the regime.
The top 40will be made available on frozen semen for use in commercial once-a-day herds as well as being progeny tested in the normal manner in Livestock Improvement's sire proving scheme herds.
