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.

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.

Dairy consumption in Asia has more than doubled over the last 25 years, and has led to more than 50% of the world’s total dairy imports now entering Asian markets. Consequently, Asian countries are seeking to improve their self-sufficiency in dairy produce by developing their local milk industries. Asian livestock importers are looking for increasing numbers of high grade dairy stock from established dairy industries in countries such as Australia and New Zealand. Unfortunately, a major problem encountered throughout Asia has been the poor performance of these exotic high grade dairy heifers when exported from their country of origin to a new, more stressful environment. This has been due to a failure to prepare for their introduction. Exotic dairy cows, particularly those from farms with high levels of herd performance, have high management requirements. If subjected to local and traditional small holder dairy farm practices, they are unlikely to produce acceptable yields of milk or may not even get back into calf. Poor management practices can lead to low growth rates, delayed breeding, stock diseases and even deaths among imported stock both before and after first calving. Managing High Grade Dairy Cows in the Tropics addresses the entire range of management practices found on tropical small holder dairy farms, highlighting those which are likely to adversely impact on heifer and cow performance, hence farm profitability. It is a companion volume to three other manuals written by John Moran: Rearing Young Stock on Tropical Dairy Farms in Asia, Tropical Dairy Farming and Business Management for Tropical Dairy Farmers.
