Residual feed intake (RFI), used as a metabolic efficiency measurement, is BW and growth rate independent and also is a moderately heritable trait. Previous research reported RFI was correlated to feed activity and behavior, ruminal fermentation nutrient digestion, body composition, blood hormones and metabolites as well as mitochondria function. Since mitochondria are responsible for producing 90% of the energy for the cell, some of the variations in growth performance and phenotypic expression of feed efficiency might be due to differences or inefficiencies in mitochondria function. Three studies were conducted to understand how AA requirement and mitochondria function influence different RFI phenotypes. The first study had 3 diets with increasing RUP (LOW, MID and HIGH) fed to continuous culture fermenters to characterize RUP supplementation using forage-based diet. We observed RUP supplementation in forage-based diets increased RUP flow from the rumen without influencing microbial fermentation. Reduced RUP for HIGH compared to MID may be due to microbial adaptation to greater RUP levels. The second study evaluated the effects of postruminal AA supply during the GP on growth performance, carcass measurements, RFI, and blood metabolites using roughage-based diet. We reported no interaction between level of bypass AA during growing phase and RFI, leading to main effects examination. Calves consuming diets with postruminal AA supplied above requirements may respond with greater gain rate, however improved growth was not sustained throughout the feeding period. As RFI decreased, steers consumed less feed and were more efficient with no change in BW during all periods. Steers classified as efficient during growing phase were not necessary in the same category during finishing phase. The last study conducted determined if mitochondria complex I, complex III and subunits (from complex I) differed among RFI phenotypes and if mitochondria measurements could account for additional differences in DMI. Examination of lymphocyte mitochondria proteins (complex I, complex I subunits and complex III) found a relationship between mitochondria band I, band VI and RFI. Mitochondrial measurements increased coefficient of determination for intake prediction. These results led to the conclusion that mitochondrial function is in part responsible for animals metabolic efficiency differences.

This 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.

This book is an up to date reference work covering all aspects of macro and trace element nutrition in farm livestock. Sufficient information is given on metabolism, functions and interactions to explain why needs, feeds and imbalances are not always easy to define or anticipate. The major emphasis is on the mineral nutrition of ruminant livestock since they are most likely to be affected by imbalances but where pigs and poultry are the more vulnerable, extensive coverage of the non-ruminant is given. This new edition of a highly successful text has been thoroughly revised and significantly expanded. Many chapters have been extensively updated and several chapters on new topics introduced. * Calcium, phosphorus, sodium and potassium are now treated separately * Over 40 new figures are presented, and extensive use made oftables to summarise important data * Chapters on trace elements have been drastically revised * Claims for enhanced availability for new chelated sources arecritically reviewed * Completely new chapters focus on: The unique need of the ruminant for elemental sulphur Occasionally beneficial elements and essentially toxic elements The improved conduct and interpretation of supplementation trials

“The value of this book cannot be overstated. As a student, many years ago, there were no comprehensive textbooks on sheep medicine, so I was lucky to have Professor Kym A Abbott as an inspiring lecturer. This book is needed by students!” Following on from Professor Abbott's first book, The Practice of Sheep Veterinary Medicine, this new text remains the ideal reference for veterinarians in farm animal practice, veterinary and animal science students, agriculturalists and sheep producers. Principally addressing sheep health, welfare and production matters in Australia, this book also covers issues that are of relevance in many other countries of the world where sheep are raised. Sheep veterinary specialist Professor Kym Abbott and his co-authors inform the reader of the science underpinning the occurrence of disease syndromes, giving special attention to commonly investigated problems related to nutrition, reproduction and helminthiasis. Other disease conditions of sheep are discussed in subsequent chapters; first on the basis of presenting signs in the case of lameness and sudden death – conditions in which signs can be attributed to disorders of a variety of body systems – and then on a body-systems basis. This new edition thoroughly revises and expands on the previous text, adding a review of the systems and strategies available to improve the welfare of sheep in extensive farming systems, a chapter on pain relief, analgesia and anaesthesia for sheep, and a chapter on metacestodes. The text is illustrated with more than 150 full-colour images and photographs.

The Mediterranean area shows a great diversity of livestock systems, depending on local resources and traditions, but also on the networking space where informational resources are available for producers. During the last decades, a lot of innovations have been conceived or introduced in the Mediterranean area, allowing livestock systems to remain competitive. The book looks at two main issues: firstly, it gives an updated review on the main innovations that significantly changed the activities of livestock production in the Mediterranean area in the recent past. Secondly, the focus lies on the extent to which these innovations improve the efficiency, ensure the socio-cultural basis or reduce the environmental impact of livestock systems. One major finding is a new vision of innovating systems based on the distinction between regulated innovation (when aims are fixed) and innovative design (when aims are questioned). Innovations reported in the book are dealing with a set of concerns. They concern the production techniques, the work organization, the equipment and infrastructures, the collective features for selection, reproduction, feeding or sanitary devices. They also concern the local organization such as product labelling, new dynamics around local breeds, collective rules for supply basin or approaches of new products for new markets. More recently, some innovations focus on environmental impacts of livestock production, due to an increasing consciousness of those kinds of problems. In the final part of the book, a round table copes with a crucial question: are traditions in Mediterranean livestock activities to be considered an obstacle or a source of innovation? This book provides a set of updated information and knowledge useful for researchers, students, extension services and policy-makers in the field of animal science.
