ABSTRACT

This book is a synoptic history of the artificial insemination service operated by the Milk Marketing Board. From a rather modest beginning in 1944–45, in which year approximately 2,600 cows were bred, the service grew rapidly to 1957–58, in which year approximately 1,399,000 cows were bred. At the end of December, 1958, the Board's A.I. service had bred 10,000,000 cows; thus, the title of the book.

In addition to this rapid growth, the A.I. service of the Milk Marketing Board should be proud of its committee organization, its methods of choosing and testing bulls, its plan of rearing bull calves, and its insemination fee of one pound. The material on selection processes and rearing of young bulls, pages 7–13, inclusive, should be of interest to all A.I. organizations.

A.I. service is available from 15 breeds, of which four are dairy, four dual purpose, and seven beef breeds. During the 14 yr., there have been major changes in the numbers bred to bulls of the various breeds.
