"A Study of Some Factors Influencing Fertility and Sterility in the Bull" by Herbert Lester Gilman is a scientific book from the early 1900s looking into the reproductive health of bulls. It explores different things that can affect if bulls can reproduce and stay healthy, like their body functions and diseases. This book is aimed at vets and breeders, showing how important bulls are for creating healthy calves and preventing the spread of infections that hurt cattle reproduction rates. It begins by explaining how important bull reproduction is to the cattle business, with the male oftern being ignore. Gilman's study aims to collect what we know about bull anatomy and how it works, investigate diseases in the bull's genitals, and see how bulls might spread infections to female cows making them sick. The initial study points to a lot of things that affect how fertile a bull is, showing we need to understand this complex part of animal science better.
