Milking of dairy cows three times a day in herds of high genetic potential

, : Milking of dairy cows three times a day in herds of high genetic potential. World Review of Animal Production 26(1): 3, 33-38

In cows of high genetic potential, changing from twice a day to three-times a day milking may be significant in realizing their full production ability. Three-times a day milking was investigated over a full lactation in 2 groups of cows: purebred and crossbred Holstein-Friesians. Lactation curves were analysed using Wood's equation. Cows were assigned to 3 production groups on the basis of first milk records: <26, 26-34 and >34 kg milk per day.

To identify other antigens with serodiagnostic potential, immun...
