Extract

Checkmate is a herd fertility monitoring service based on information recorded on National Milk Records (NMR) operated by the Milk Marketing Board. The aims of Checkmate are:

To provide a regular review and analysis on a herd basis of overall and monthly fertility results.

To breakdown the calving interval into its components of interval from calving to first service, interservice intervals and service success.

To provide veterinary surgeons with information on which to base advice and treatments and the means of evaluating past treatments.

In the year ending May 1985 322 herds have subscribed to Checkmate. The whole sample has been analysed and also two sub-samples, the top and bottom 10 per cent, selected by the days from calving to assumed conception. As there is no pregnancy diagnosis information on NMR conception Is assumed if no re-service date is recorded within 60 days of a service.
