Book excerpt: "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.

Available in PDF, EPUB and Kindle. Book excerpt: A detailed study of grasslands and the management and investigation of grazing systems for animal production. The twenty-one chapters have been written by internationally recognized experts from Australia, the USA, the United Kingdom and New Zealand, and cover four main areas of interest. The first group of chapters is concerned with the evolution and ecology of grasslands and the behaviour of grazing animals. The second group deals in considerable depth with the intake of food and the nutritional value of different kinds of grassland (tropical, temperate and mediterranean), covering the most important tame' pastures. Arctic and multiple-purpose grazing are then discussed with emphasis on the social factors governing the use of resources. The following nine chapters deal with animal production technologies and management, including forage crops, fertilizer use, supplements for grazing animals, drought, detrimental substances in plants, and computer modelling of grazing systems. The final chapter integrates all this information and discusses the management of grazing systems, including decisions about subjects such as stocking rate and subdivision.

Available in PDF, EPUB and Kindle. Book excerpt: From the PrefaceThe objective of this book is to review the basic knowledge and methodology of feeding grazing ruminants in tropical and semitropical countries. It is hoped this information will be of use to farmers, research specialists, teachers, students, extension specialists, feed manufacturers, and others throughout the world concerned with the nutrition of grazing ruminants. A unique feature is the identification of nutritional limitations of grazing ruminants in the tropics, which will be beneficial for increasing animal production efficiency through the application of improved nutrition. A large number of photographs illustrate nutritional deficiencies and conditions in tropical countries.This book contains 18 chapters concerned with the nutrition of grazing ruminants. The first chapter deals with the contributions, locations, and various types of ruminants and their importance to human welfare in the tropics and subtropics. Chapters 2 - 4 progress through nutrient requirements of grazing ruminants in warm climates, the effects of tropical heat on these requirements, and water requirements for ruminant species. Chapters 5 - 7 discuss grass and legume forage species suitable for tropical regions, pasture management procedures, and energy-protein supplementation programs needed during the extensive dry periods. The importance of tropical forages and soils toward meeting mineral requirements is discussed in Chapter 8. Chapters 9 -14 contain concise, up-to-date summaries of minerals emphasizing mineral status, incidence of mineral deficiencies and excesses in tropical regions, and benefits and methods of mineral supplementation for grazing ruminants are discussed in Chapters 15 - 17. Chapter 18 reviews vitamin nutrition considerations for ruminants consuming tropical forages.

Download or read book Supplementary Feeding of Sheep and Beef Cattle written by David G Hinton and published by Landlinks Press. This book was released on 2007-01-22 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical guide is a tool designed for graziers to use in their day-to-day decision-making about livestock nutritional needs, feeding options, condition and health. Pasture supplements are expensive and should not be wasted, yet under-nutrition has an even greater economic effect resulting from low conception and progeny survival rates, poor growth rates, failure to meet market targets and tender fleeces in sheep. Supplementary Feeding of Sheep and Beef Cattle shows how to get the nutritional balance right and avoid costly repercussions from incorrect or inadequate feeding. The key topics covered will be particularly useful in drought situations, but also in seasonal pasture shortages, when the nutrient value of pastures is low. Practical tables and worksheets are provided as key tools, enabling livestock producers to make timely and cost-effective decisions about supplementary feeding.

Download or read book Nutrient Requirements of Beef Cattle written by Subcommittee on Beef Cattle Nutrition and published by National Academies Press. This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Nutritive Value of Tropical Pastures for Grazing Cattle written by Luiz Carlos Lopes Freire and published by . This book was released on 1981 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study describes experiments aimed at manipulating and evaluating the nutritive value of tropical pastures for grazing cattle. Before commencing experiments with grazing cattle, an experiment was conducted with sheep to determine whether the digestion of mature tropical grass forage varied appreciably from that expected from temperate grass of similar composition. Results from this experiment indicated that despite the low intake and digestibility of mature tropical grass, the digestible fraction of this forage behaved in ways predicted from published data obtained with temperate species. It was concluded that principles of rumen function and ruminant nutrition established with temperate forage species could validly be applied to tropical forage species. The subsequent experiment was aimed at avaluating the effects of superphosphate fertiliser on the botanical and chemical composition and nutritive value of the diet selected by cattle grazing Stylosanthes-native grass pastures. The data obtained in this experiment showed that superphosphate fertiliser improved the nutritive value of the diet selected. Animals grazing fertilised pastures had a significantly higher organic matter intake than those grazing unfertilised pastures during the wet and dry seasons but not during the wet-dry transition. This lower consumption with unfertilised pastures during the wet and dry seasons was associated with lower digestibility of the diet selected and possibly also with lower phosphorus content during the wet season. There was no evidence that higher organic matter intake observed for fertilised pastures was associated with a greater production of legume nor with the ingestion of a greater proportion of legume in total diet. It appears that the amount of legume in the diet was mainly determined by the time of the year and by the proportion of legume available in the pasture. Three experiments were conducted to evaluate the use of monensin sodium for manipulating rumen fermentation on the nutritive value of native pasture. The first experiment studied the effect of monensin on liveweight change of steers grazing a native pasture and the second examined this effect on the nutritive value of the forage selected during the wet and dry seasons, while the third used penned animals to study the effect of monensin on the nutritive value and utilisation of native pasture hay with and without nitrogen supplements. Results from these experiments indicated that monensin was efficient in changing the rumen fermentation patterns by increasing the production of propionic acid and reducing acetic and butyric acids. However, no beneficial effects on intake and liveweight gain of grazing animals was observed by the use of monensin during the wet or dry season. Although supplementation of the low quality hay with urea plus formaldehyde-treated casein produced an increase in the digestible organic matter intake (largely by improving both intake and digestibility), no benefit for the animal was achieved by the use of monensin. Comparisons made between predicted and observed liveweight gain of cattle grazing tropical pastures suggest that liveweight gain could accurately predicted from digestible organic matter intake by the use of tables presented by the Commonwealth Agricultural Bureaux - CAB (1980). However, estimates of feed consumption from formulae presented by the CAB underestimated the observed intakes by 25% during the wet season. There is, therefore, an urgent need for the development of equations that would allow the estimation of the digestible organic matter intake. A relationship between organic matter digestibility and digestible organic matter intake is proposed and its limitations are discussed. Although it is clear that much research is needed to elucidate problems of nutrition of cattle grazing tropical pastures, the results from this investigation suggest that the CAB system does provide a useful framework to base the development of system for livestock feeding for tropical as well as for temperate Australia.
