Book Description
Looking for a technical but practical science-based book on Dairy Calf and Heifer Feeding and Management? Are you a field person such as a nutritionist or veterinarian or calf/heifer specialist, a commercial dairy or calf/heifer operation, a student, or dairy scientist? Al Kertz has spent 46 years doing calf and heifer research, making on-farm visits and evaluations, conducting dairy training of employees, interacting with scientists and technical people, publishing 17 scientific articles in this area, reading and studying the scientific literature, and writing articles since 2001 for Feedstuffs (>110) and Hoard's Dairyman (> 59). After periodic requests to publish a book in this area and with the approval of Feedstuffs, this book has been compiled by amalgamating, organizing, and editing many Feedstuffs' articles into a book with 9 chapters encompassing an Introduction and USA Demographics, Colostrum, Milk Replacers, Calf Starters, Water, Post-weaned Transition Month, Heifers, Other Management Issues, and Evaluations. The focus of the book is on some key concepts and practices, and it can serve as a technical reference for a variety of people. While its focus is on the USA, Kertz has spent nearly 20 years doing consulting work in over 20 countries where he finds the science and applications similar, albeit in the metric system. Alois (Al) F. Kertz grew up on a small Missouri dairy farm. He earned B.S. and M. S. degrees in dairy husbandry and nutrition from the University of Missouri under the tutelage of John Campbell before completing 2 years of US Army active duty as a research Nutrition Officer, and then managing food supply for military operations in Thailand. At Cornell University, his major professor was J. T. (Tom) Reid with a Ph. D. thesis project on growth and development of cattle. That became a great platform for understanding and working with calves, heifers, dry cows, and lactating cows and their bodily changes and metabolism. In 1973, he began employment under the direction of J.P. Everett, Jr. at Ralston Purina Company. He became another mentor from whom Al began to learn about calves and heifers. The basis for this book are the many Feedstuffs columns which he has written--many of which are excerpted and edited into this book; the Young Calf Model from the 2001 Dairy NRC publication for which he was a reviewer; and the 100-year review in the December 2017 Journal of Dairy Science on Calf Nutrition and Management made possible only through the major work by 5 co-authors: Mark Hill, Jim Quigley, Jud Heinrichs, Jim Linn, and Jim Drackley. In addition, there were the on-going grounding and understanding of practical applications provided by visiting, reviewing, and developing recommendations for many dairy operations in the U.S. and in many other countries as well. These visits often provided insights into how science could meet application. That became an on-going learning process for if the science was not applicable, then maybe we did not understand the science, or how to apply it. This book is designed to be a handy reference for field people and students, and as a reference for scientists in their teaching and research to understand concepts and how they are applied to feeding and managing dairy calves and heifers.

Book Description
From birth to first calving, the replacement heifer undergoes tremendous changes anatomically as well as in feeding and management practices. The calf changes from being a pseudo-monogastric to a full ruminant within a period of two months. During the same period, the calf is fed colostrum, milk, or milk replacer, and starter with or without hay. Notably, the lifetime milk production and health of a dairy cow is highly dependent on early life nutrition and management of the calf and, subsequently, the heifer. Hence, animal scientists continue to investigate critical areas such as colostrum feeding, the level of liquid feeding, gut microbial succession, energy and protein levels, housing, health management, and their interactions with the animal in an effort to help dairy producers raise successful and sustainable dairy enterprises.

Book Description
The seventh edition of this classic text offers expanded material on traditional Dairy Herd Improvement (DHI) records, a new chapter on the computer as a dairy management tool, increased coverage of financial management, and thoroughly revised chapters on dairy nutrition that include the latest concepts in protein nutrition, forage evaluation, and feeding management. Like previous editions, the text focuses on showing how to use current tools and practices of successful dairy herd managers to produce and market milk and cattle more profitably.

Book Description
An indispensable resource for the dairy farmer or veterinarian, the researcher, teacher, or advanced student, this book puts the cutting–edge science of raising dairy calves into an accessible, usable form. Geared to those with a basic understanding of principles of animal nutrition and husbandry, the volume gives a comprehensive account of all aspects of calf rearing, from the rudiments of anatomy and development through the practicalities of feeding and housing. The Development, Nutrition and Management of the Young Calf begins with an overview of how the calf′s digestive system develops, highlighting the period of transition from preruminant to ruminant digestion. Here the authors provide information essential to understanding nutritional needs and restrictions during the liquid–feeding phase in the young calf as well as those factors that govern the development of a functional rumen. Major emphasis is given to the energy and protein requirements of the young calf, with attention to the effects of environmental temperature on energy requirements. The authors also review the adequacy of current National Research Council recommendations on the energy and protein requirements of young calves. They discuss the management, nutrition, and care of the pregnant cow as well as calving management necessary to deliver a healthy calf. Other topics include liquid–feeding systems, formulation and use of milk replacers and starter feeds, the weaning process, housing principles, and the interactions of nutrition and disease
