Paperback. Condición: New. Print on Demand. Drawing striking conclusions from a large body of evidence, this book is a masterclass on the interrelationship of dairy cattle conformation and milk producing capacity. The author, a pioneering scientist in this field, has carried out an exhaustive study of the characteristics of high-performing Jersey cows, examining the correlation between milk yield and various physical attributes. Through rigorous analysis of data, the author reveals a discrepancy between the ideal cow and the average cow, highlighting areas where improvement can be made. This book offers invaluable insights for dairy farmers, cattle breeders, and anyone with an interest in understanding the factors that contribute to bovine milk production. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Paperback. Condición: New. Print on Demand. This book is a study of the relationship between milk yield and butterfat percentages in Holstein-Friesian cattle as determined by testing cows over a period of seven and three hundred sixty-five days. The author examines whether the seven-day test results can be used to accurately predict longer-term performance. The author provides data that challenges the notion that a seven-day butterfat percentage will inevitably be higher than a 365-day percentage, revealing the nuances of the relationship between these metrics. It also questions whether the seven-day test effectively differentiates between cows' abilities, or whether factors such as feeding and management influence these results. Ultimately, the research in this book contributes to the larger discussion of the accuracy and significance of short-term testing as a predictor of long-term milk production and butterfat percentages in dairy cattle. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Taschenbuch. Condición: Neu. Neuware - 'Milk Secretion' provides a comprehensive scientific examination of the biological and physiological processes involved in the production of milk in dairy cattle. Written by John W. Gowen, a noted expert in the field of genetics and animal science, this work delves into the intricate factors that influence milk yield and quality. The book explores the relationship between heredity and productivity, offering a detailed analysis of how genetic traits are passed down and how they manifest in the dairy industry.Throughout the text, Gowen investigates the internal mechanisms of the mammary gland, the impact of nutrition on secretion, and the statistical correlations between physical characteristics and milk output. This work serves as a foundational study for anyone interested in dairy science, animal husbandry, or the application of genetic principles to agriculture. By synthesizing data from extensive breeding experiments and physiological observations, 'Milk Secretion' remains a significant historical reference for understanding the evolution of modern dairy production techniques. Scholars and practitioners alike will find value in its rigorous approach to one of the most vital aspects of agricultural science.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. This work was reproduced from the original artifact, and remains as true to the original work as possible. Therefore, you may see the original copyright references, library stamps (as most of these works have been housed in our most important libraries around the world), and other notations in the work.This work is in the public domain in the United States of America, and possibly other nations.
