The only rumen protozoa lab guide featuring line drawings created by a leading scientist in the field Laboratory Manual for Classification and Morphology of Rumen Ciliate Protozoa is a unique lab guide for learning how to count and identify rumen protozoa. In this guide, Professor Dehority has created line drawings of rumen protozoa that emphasize morphological features and size measurements. The book also provides keys for identifying genera and species, and it contains classifications and descriptions of the different orders and families of rumen ciliate protozoa. Procedures for counting rumen protozoa and identifying individual species are included as well. Laboratory Manual for Classification and Morphology of Rumen Ciliate Protozoa will be an excellent identification guide for protozoologists, microbiologists, dairy scientists, and any researcher or student working with rumen protozoa.

The Preface to the first edition of this book explained the reasons for the publication of a comprehensive text on the rumen and rumen microbes in 1988. The microbes of the ruminant's forestomach and those in related organs in other animals and birds provide the means by which herbivorous animals can digest and obtain nutriment from vegetation. In turn, humans have relied, and still do rely, on herbivores for much of their food, clothing and motive power. Herbivores also form the food of carnivorous animals and birds in the wild. The importance of the rumen microorganisms is thus apparent. But, while a knowledge of rumen organisms is not strictly neces sary for the normal, practical feeding of farm animals, in recent years there has been much more emphasis on increasing the productivity of domesti cated animals and in rearing farm animals on unusual feedstuffs. Here, a knowledge of the reactions of the rumen flora, and the limits to these reactions, can be invaluable. In addition, anaerobic rumen-type microor ganisms are found in the intestines of omnivores, including humans, and can be implicated in diseases of humans and animals. They are also found in soils and natural waters, where they playa part in causing pollution and also in reducing it, while the same organisms confined in artificial systems are essential for the purification of sewage and other polluting and toxic wastes.

Asaresultofvarioushumanactivities,suchasincreaseinhumanpopulation,decrease in arable land due to soil degradation, urbanization, industrialization and associated increase in the demand for livestock products, dramatic changes are occurring in the global ruminant livestock sector. These changes includeshift inthesize of regional livestock populations and in the types of management and feeding systems under which ruminant livestock are held, and increased demand of a wider range of quality attributes from animal agriculture, not just of the products themselves but also of the methods used in their production. The livestock sector will need to respond to newchallengesofincreasinglivestockproductivitywhileprotectingenvironmentand human health and conservingbiodiversity and natural resources. The micro-organisms in the digestive tracts of ruminant livestock have a profound in?uence on the conversion offeedinto end products, which can impact on the- imal and theenvironment. As the livestock sector grows particularly in developing countries, there will be an increasing need to understand these processes for b- ter management and use ofbothfeed and other natural resources that underpinthe development of sustainable feeding systems.

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.

The increasing demand for high-quality beef has led to the necessity of including higher levels of cereal grains and its by-products into cattle diets. In this context, adequate nutrition of beef cattle involves knowledge of energy and nutrient requirements to define specific nutritional strategy. The evolution feeding strategies to feedlot cattle depends on advances related to ruminant metabolism, as well as to the ruminal microbiota. Furthermore, a continuous flow of knowledge development in feedlot cattle nutrition and metabolism is important, as new feeds, additives, or even new management approaches come up very often, and new scenarios will impact protein and energy metabolism, the ruminal microbiota, and also strategies to modulate ruminal fermentation to improve health and performance of feedlot cattle. Overall, the main goal of this Research Topic is to contribute with recent advances in feedlot cattle nutrition and metabolism, addressing studies related to the nutrition of high-performing ruminants, with a special emphasis on the feed efficiency, ruminal fermentation and animal performance. Furthermore, we are interested in different aspects of sustainability and efficiency. In other words, the goal is to attract studies that address such issues, both from a general perspective and in relation to specific domains. Hence, the integration of existing and current knowledge will help refine strategies to optimize the performance of feedlot cattle.
