Paperback. Condición: New. Print on Demand. This book comprehensively presents the discovery of Francois Guenon regarding milk production in cows. Guenon observed a crucial correlation between a cow's milk production capability and certain marks on their bodies, primarily found in the region between the hind legs and the female…organs. These milk marks or 'mirrors', as Guenon termed them, provided valuable insights into the quantity and duration of a cow's lactation period, information that was previously unknown or unreliable. The author of this book has simplified and organized Guenon's extensive research into eight distinct classes and orders of milk mirrors, making it accessible and practical for dairy farmers to identify and select cows with superior milk production potential. Beyond merely identifying milk marks, the author emphasizes the importance of matching bulls and cows with compatible mirrors to sustain and improve productivity in subsequent generations. By understanding the principles outlined in this book, cattle breeders can breed and select animals to increase their herd's milk yield significantly. This book is a valuable resource for farmers and breeders seeking to optimize their dairy operations, as it empowers them with the knowledge to make informed decisions based on Guenon's groundbreaking discovery.
