DOWNLOAD EBOOKRearing young stock for replacement heifers is probably one of the least well understood and practiced aspects of herd and feeding management on dairy farms throughout the world, particularly on smallholder 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, labor 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 Asiaencourages the smallholder 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. - Shows how to reduce mortality rates of milk fed and weaned heifer replacements in the tropics. - Covers disease prevention and treatment to ensure a longer lifespan of the milking herd. - Companion volume to three previous manuals written by John Moran: Tropical Dairy Farming, Business Management for Tropical Dairy Farmersand Managing High Grade Dairy Cows in the Tropics.

DOWNLOAD EBOOKAn 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

DOWNLOAD EBOOKAnimal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. - Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management - Addresses the urgent issue of sustainability in modern animal agriculture - Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide

DOWNLOAD EBOOKTropical Dairy Farming is a manual designed for use by dairy production advisors working in tropical areas, especially in South-East Asia. It aims to increase the productivity of small holder dairy farmers in the humid tropics by improving the feeding management of their livestock. It shows how to provide dairy cows with cost-effective feeds that match small holder farming systems and discusses the major obstacles to improving feeding management in the humid tropics. The author shows the benefits and drawbacks of various feed components and the calculation of balanced diets based mainly on forages combined with some supplementary feeding. Diseases and problems associated with unbalanced diets are also covered, as well as important information on growing and conserving quality forages as silage. The book draws on examples from a variety of countries including Indonesia, Malaysia, Thailand, Vietnam, China, East Timor and the Philippines.

DOWNLOAD EBOOKThis widely used reference has been updated and revamped to reflect the changing face of the dairy industry. New features allow users to pinpoint nutrient requirements more accurately for individual animals. The committee also provides guidance on how nutrient analysis of feed ingredients, insights into nutrient utilization by the animal, and formulation of diets to reduce environmental impacts can be applied to productive management decisions. The book includes a user-friendly computer program on a compact disk, accompanied by extensive context-sensitive "Help" options, to simulate the dynamic state of animals. The committee addresses important issues unique to dairy science-the dry or transition cow, udder edema, milk fever, low-fat milk, calf dehydration, and more. The also volume covers dry matter intake, including how to predict feed intake. It addresses the management of lactating dairy cows, utilization of fat in calf and lactation diets, and calf and heifer replacement nutrition. In addition, the many useful tables include updated nutrient composition for commonly used feedstuffs.

DOWNLOAD EBOOKAir Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
