The Development, Nutrition, and Management of the Young Calf by Carl L. Davis,James K. Drackley Pdf

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

Calf and Heifer Feeding and management by Zhijun Cao,Michael Van Amburgh Pdf

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.

Rearing Young Stock on Tropical Dairy Farms in Asia by John Moran Pdf

Rearing young stock for replacement heifers is probably one of the least well understood and practised aspects of herd and feeding management on dairy farms throughout the world, particularly on small holder dairy farms in the tropics. This book addresses all the major concerns of the small holder dairy farmer in Asia. It shows how to attain optimal growth in young stock, so that as cows, they can calve at an appropriate early age at the lowest cost and promptly substitute for any cows culled from the milking herd. This provides continuing returns on the investments of feed, labour and other farm resources. Low reproductive rates and high calf mortality are the major causes of reproductive wastage. This has a direct bearing on culling and replacement strategies and on genetic improvement. In many tropical countries, calf mortality can be as high as 50%. In some areas this can be due to climatic stress on temperate or crossbred stock. While climatic stress compounds the other hazards of calf life, high calf mortality is usually due to diseases and poor feeding management. Rearing Young Stock on Tropical Dairy Farms in Asia encourages the small holder dairy farmer to maintain their investment in replacement heifers and gives them the tools necessary to achieve realistic targets for mortalities, live weight gain, mating age, and age and live weight at first calving. It is a companion volume to three previous manuals written by John Moran: Tropical Dairy Farming, Business Management for Tropical Dairy Farmers and Managing High Grade Dairy Cows in the Tropics.

Nutrition and the Welfare of Farm Animals by Clive J. C. Phillips Pdf

This book explores the importance of good nutrition in ensuring an adequate standard of welfare for farm animals. It is often not realized that farm animals can suffer when they are fed unsuitable diets, which may be because these diets are more economic or the farmer does not know how to rectify poor nutrition. This book reveals how to recognize and deal with feeding problems in farm animals, when the animal’s behaviour is indicating a deficiency, through oral stereotypies for example. Feeding livestock in emergency situations can present special challenges, and the availability of clean and potable water, one of the essential components of life, can also be an unrecognized problem for many farm animals. Feeding farm animals effectively is rarely recognized for the major welfare issue that it is. We may assume that animals in intensive husbandry conditions have adequate feed, yet it is often too concentrated and designed primarily to immediately maximize production from the animals, in the form of growth, milk yield or reproduction. In extensive rangeland conditions adequate feed supply also cannot be assured, potentially leading to undernutrition with serious consequences for the health and even survival of livestock. This book will provide a much-needed review of the relationships between nutrition and the welfare of farm animals.

Information Resources on the Care and Welfare of Beef Cattle by Cynthia Petrie Smith Pdf

One of the main animal welfare concerns in beef cattle production is that of pain and distress. Dehorning, castration, and branding are husbandry procedures which can cause pain and discomfort. Less acute but still distressful are those issues related to the animal environment. Extreme natural conditions can result in cattle that are heat and/or cold stressed. Drought and the resulting overstocking for available feed resources can also reduce body fatness. These are important welfare issues in modern beef production. The following bibliography explores these issues and more and should provide a useful resource for scientists, veterinarians, extension specialists, students, and others.

Gaining the edge in ruminant production by S. Andrieu Pdf

"Globally, dairy and meat production has become an extremely competitive industry. The world milk production is predicted to grow significantly by 2020 with the emergence of new consumers in developing countries. Yet, there is still intense competition for the industry to attract and retain consumers in the more established markets. Consumers continue to demand safe, high quality milk and meat products at competitive prices compared to other high protein food alternatives. To ensure the sustainability of both dairy and beef industries, producers must endeavour to seek new technologies to improve production efficiency whilst lowering the cost of production to produce a quality product. This edited collection of papers is taken from a seminar that brought together some of the world’s leading authorities in the field of ruminant nutrition and production. The fundamental theme is to re-examine the current trends in productivity within the dairy and beef industries, and to identify nutritional and managerial means to improve competitiveness. The papers also consider the importance of animal health together with novel strategies for disease control. ‘Gaining the edge in ruminant production: Nutritional strategies for optimal productivity and efficiency’ is aimed at nutritionists, veterinarians and animal producers as well as students and researchers studying animal and applied biological sciences"

Dairy Calf and Heifer Feeding and Management: Some Key Concepts and Practices by Alois (Al) F. Kertz Pdf

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.

Engineering Rumen Metabolic Pathways: Where We Are, and Where Are We Heading by Emilio M. Ungerfeld,C. James Newbold Pdf

Ruminants were domesticated in the Middle East about 10,000 years ago and have since become an inseparable part of human diet, society, and culture. Ruminants can transform inedible plant fiber and non-protein nitrogen into meat, milk, wool and traction, thus allowing human utilization of non-tillable land and industrial by-products. The nutritional flexibility of ruminants is conferred by the rumen´s complex microbial community. Driven by rising income and population growth in emergent economies, the global demand for livestock products, including milk and meat from ruminants, has been increasingly growing, and is predicted to continue growing in the next few decades. The increase in production necessary to satisfy this rising demand is putting much pressure on already dwindling natural resources. There are also concerns about the emissions of methane and nitrous oxide, potent greenhouse gases associated to ruminant production. The need to make ruminant production more efficient in the use of natural resources poses a big challenge to ruminant science, and within it, rumen microbiology. Recent years have seen important advances in basic and applied rumen microbiology and biochemistry. The knowledge generated has significant implications for the efficiency and sustainability of ruminant production and the quality of ruminant products for human health. The present compilation is an update of recent advances in rumen microbiology and ruminant digestion and fermentation, including original research, reviews, and hypothesis and theory articles. We hope that the experimental results, discussion, models and ideas presented herein are useful to foster future research contributing to sustainable ruminant production.
