A review of Grade Herd Recording during the 1963-64 season.
THERE was a substantial increase in the number of cows which were recorded in 1963-64 compared with 1962-63 (23,520 and 22,635 respectively).
This season's figure represents 20.4 per cent, of all cows in the dairying districts.
The number of cows which completed lactation and therefore whose yields were included in the averages, rose from 17,258 to 19,011.
