Herd Bull Fertility

James E. Drayson


James Drayson has spent a lifetime researching and teaching about cattle breeding and fertility, with 35 years of experience in measuring bulls from a fertility standpoint. He followed 1,500 bulls from birth to death and recorded findings that are unequaled by any other researcher. Herd Bull Fertility will teach you how to recognize whether a bull is fertile even before the semen test. This manual, generously illustrated with photographs and diagrams, is a must for the cattle grower choosing a bull for his breeding program.
