  1. I was very happy to read that mr Lewis is reaping rewards from keeping guernseys.
    Are would be interested to know how his fertility compares between the two breeds.
    neither would appear to be pushed !

  2. “an impressive case for keeping Guernseys” – and with better fertility, less mastitis, few if any calving or foot problems, much lower vet fees and much higher longevity a 5% better margin could easily result in a 50% better profit!
