 to five years' work in grading up, states that since following this 

 practice of grading to the Guernsey, the yearly yield of the herd 

 has increased over 100 pounds butter fat per cow. N. I. Bowditch 

 of Massachusetts, a long-time Guernsey breeder, writes :

 testing all the way from 4.5 to 5.6. I have crossed the Guernsey bull with
