Download or read book Normal Growth of Dairy Heifers written by Charles Lloyd Burlingham and published by . This book was released on 1914 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Office of Farm Management reports (March, 1914) that there are 21,749,651 dairy cows in the United States. Considering the average productive life to be six of seven years, it is evident that 3,000,000 to 3,500,000 heifers must be grown each year to maintain the present number of dairy cows. The Government estimate of the cost of raising each to a productive age is $61.41. It therefore is important, not only that they be economically grown, but that they make such growth as will result in greatest production at maturity. A review of literature shows that little has been done experimentally on the growth of dairy cattle. While the scientific facts of growth have been worked out with man and with laboratory animals, almost no application of these facts has been made to the development of farm animals. The basis of this thesis is a study of growth of dairy heifers from birth to first parturition. The development of animals kept under different planes of nutrition is considered and compared with that made by those fed rations which are thought to be suitable for normal growth. From this data a standard of growth is calculated showing the size a heifer should attain at any particular age.
Download or read book Bovine Reproduction written by Richard M. Hopper and published by John Wiley & Sons. This book was released on 2014-08-18 with total page 2206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bovine Reproduction is a comprehensive, current reference providing information on all aspects of reproduction in the bull and cow. Offering fundamental knowledge on evaluating and restoring fertility in the bovine patient, the book also places information in the context of herd health where appropriate for a truly global view of bovine theriogenology. Printed in full color throughout, the book includes 83 chapters and more than 550 images, making it the most exhaustive reference available on this topic. Each section covers anatomy and physiology, breeding management, and reproductive surgery, as well as obstetrics and pregnancy wastage in the cow. Bovine Reproduction is a welcome resource for bovine practitioners, theriogenologists, and animal scientists, as well as veterinary students and residents with an interest in the cow.

This book was released on 2014-11-01 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study was to define connections between heifer rearing intensity (average daily weight gain, age at first calving, body condition scores during the rearing phase) and production performance, fertility and longevity of dairy cows in the production period with regard to overall herd economics. A dairy herd is a complex system consisting of two interconnected parts - the milking herd and the replacement herd. Management decisions regarding replacement policy can have profound effects on the profitability of the farm as a whole. Although it is often pursued as a management target, low AFC does not always lead to the most profitable outcome in dairy herd management.
Download or read book Calf and Heifer Feeding and management written by Zhijun Cao and published by MDPI. This book was released on 2020-12-11 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Dairy Calf and Heifer Feeding and Management Some Key Concepts and Practices written by Alois (Al) F. Kertz and published by Outskirts Press. This book was released on 2019-07-31 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
