Book Description
"An up-to-date review of the pasture and supplementary feed resources available to the New Zealand pastoral livestock industry, and the energy and protein requirements of these livestock. The interactions between animals and their feed resources ultimately determine both the quantity and quality of the feed consumed and thus the level of animal production. An understanding of this area is key to the successful allocation of feed resources. Although the principles discussed in the early chapters are common to all grazing animals, certain aspects of their application are species or system specific, and chapters address these issues. The environmental impact of grazing pastures and supplementing grazing animals is also addressed."--NZSAP Web site

Book Description
This book presents strategies for feeding energy and protein supplements to pasture-fed dairy cows and examines the potential economic benefits. Effective supplementary feeding of concentrates is critical to the success of all dairy farms. This book is a substantially revised edition of 'Feeding Concentrates: Supplements for Dairy Cows' DRDC 1993. It focuses on feeding concentrates to pasture fed cows to achieve high milk production per cow per hectare, and will assist farmers to decide which supplements give the best results in their particular situation. The benefits that arise from supplementary feeding include higher stocking rates, promotion of growth in heifers and young cows; better body condition score and increased lactation length when pasture is less available; improved pasture use; reduced cost per tonne of pasture eaten; flexibility to increase milk production when milk prices are high; and increased milk protein content when the energy content in pasture is low. This edition has thoroughly reviewed the issues and clearly documents the results of research particularly for grains supplementation. The summaries and recommendations in each chapter will be particularly helpful to dairy farmers in making best management decisions relating to concentrate feeding.

Book Description
This book is the first detailed and comprehensive guide to the use of feedpads in the dairy industry, from planning and construction to day-to-day management, written especially for farmers. With ongoing droughts and access to water driving up the cost of conserved forages and feeding concentrates, feedpads offer flexible and efficient systems to maximise returns on feeding expensive supplements to grazing dairy cows, and form part of the risk management strategy for dairy farms. Feedpads for Grazing Dairy Cows covers all the aspects of animal husbandry involved in running a successful system and addresses key issues such as formulating rations to balance grazed pasture, management of farm labour and effluent management. The key principles of dairy nutrition are explained along with the concept of partial mixed rations and the range of potential ingredients. The authors also cover the physical features of feedpad design and construction and provide a checklist for planning a feedpad. They discuss important issues such as cow welfare, animal health and the management of effluent, including cleaning the pad, storing and recycling these solids and liquids on farm while minimising feedpad odours, flies and vermin. This book demonstrates a wide range of long-term economic benefits and will play an important role in helping dairy farmers achieve higher farm profitability.

Book Description
As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

Book Description
Recent Advances in Animal Nutrition-1981 is a collection of papers that discusses the effects of dietary fat on milk composition, relating it to the biochemistry of fat synthesis in the mammary gland. The influence of concentrates on milk composition as well as the pattern and level of concentrate feeding on milk output are also covered. The book describes the need for better utilization of grass and grass products in dairy production, the mineral and trace element requirements of pigs; the importance of anion-cation balance in poultry diets and its effects on performance levels; and the selenium and cobalt requirements of ruminants. The problems of medicinal residues in animal products and the toxicological effects of aflatoxin residues in animal products are also considered. People involved in agriculture, dairy production and animal nutrition will find the book useful.

Book Description
Tropical 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.

Book Description
This book offers the contributions of active researchers and leading experts in the field of grassland management and grass utilization. Coverage follows the food chain, moving from the big picture to basic principles of grassland management and effects on herbage quality, intake and nutrient flows. Rather than focus separately on soil-plant interactions, plant production, animal nutrition, animal production or product quality issues, this book takes a more integrated approach.
