Book Description
Young range beef cows consuming low-quality forage may result in an imbalance of energy and metabolizable protein, which can negatively affect the nutrient status of the cow and reproductive performance. In a 2-yr study conducted at Gudmundsen Sandhills Laboratory near Whitman, NE, 2- and 3-yr-old May-calving range cows (n = 181) grazing native range were individually supplemented daily with one of four supplements: 1) mineral with a target intake of 113 g/d (MIN), 2) MIN with 200 mg per head of Rumensin to with a target intake of 113 g/d (RUM), 3) MIN with a 226 g/d of high RUP sources with a target intake of 340 g/d (RUP), or 4) dried distiller grains at a rate of 907 g/d (DDG). Each year, supplementation started approximately 30 d before the breeding season and continued throughout the 45-d breeding season. Cow body weight (BW), body condition score (BCS), and blood samples were taken biweekly beginning 40 d postpartum and ending 125 d postpartum. Milk production was collected at approximately 60 d postpartum. Cow BW, BW change, and BCS were not different (P ≥ 0.29) between supplementation treatment. Pregnancy rates were 82, 83, 92, and 89% for MIN, RUM, RUP, and DDG fed cows, respectively (P = 0.76). Calf BW at birth, 60-d BW, and 205-d BW were not affected (P ≥ 0.19) by dam supplementation. Cows receiving DDG had increased (P = 0.05) circulating serum glucose concentrations compared to MIN, with no difference between RUM and RUP. Cows receiving DDG and RUP had increased (P = 0.01) circulating serum urea nitrogen concentrations. Postpartum supplements did not affect (P = 0.13) circulating serum non-esterified fatty acid concentration. Milk production was not affected (P ≥ 0.11) by postpartum supplements. The results from this study suggest that supplying RUP, energy, or ionophores did not increase cow BW or BCS but, cows were able to maintain these metrics. However, additional protein and energy tended to increase glucose and serum urea nitrogen. The number of years and cows in this study may not have been enough to find differences among supplementation strategies; however, additional years and data may change observed results in this study.

Book Description
"Globally, dairy and meat production has become an extremely competitive industry. The world milk production is predicted to grow significantly by 2020 with the emergence of new consumers in developing countries. Yet, there is still intense competition for the industry to attract and retain consumers in the more established markets. Consumers continue to demand safe, high quality milk and meat products at competitive prices compared to other high protein food alternatives. To ensure the sustainability of both dairy and beef industries, producers must endeavour to seek new technologies to improve production efficiency whilst lowering the cost of production to produce a quality product. This edited collection of papers is taken from a seminar that brought together some of the world’s leading authorities in the field of ruminant nutrition and production. The fundamental theme is to re-examine the current trends in productivity within the dairy and beef industries, and to identify nutritional and managerial means to improve competitiveness. The papers also consider the importance of animal health together with novel strategies for disease control. ‘Gaining the edge in ruminant production: Nutritional strategies for optimal productivity and efficiency’ is aimed at nutritionists, veterinarians and animal producers as well as students and researchers studying animal and applied biological sciences"

Book Description
This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.
Knowledge Sovereignty Among African Cattle Herders

ISBN: 1787353125
Category : Political Science
Languages : en
Pages : 216
Book Description
Beni-Amer cattle owners in the western part of the Horn of Africa are not only masters in cattle breeding, they are also knowledge sovereign, in terms of owning productive genes of cattle and the cognitive knowledge base crucial to sustainable development. The strong bonds between the Beni-Amer, their animals, and their environment constitute the basis of their ways of knowing, and much of their knowledge system is built on experience and embedded in their cultural practices. In this book, the first to study Beni-Amer practices, Zeremariam Fre argues for the importance of their knowledge, challenging the preconceptions that regard it as untrustworthy when compared to scientific knowledge from more developed regions. Empirical evidence suggests that there is much one could learn from the other, since elements of pastoralist technology, such as those related to animal production and husbandry, make a direct contribution to our knowledge of livestock production. It is this potential for hybridisation, as well as the resilience of the herders, at the core of the indigenous knowledge system. Fre also argues that indigenous knowledge can be viewed as a stand-alone science, and that a community’s rights over ownership should be defended by government officials, development planners and policy makers, making the case for a celebration of the knowledge sovereignty of pastoralist communities Praise for Knowledge Sovereignty Among African Cattle Herders ‘This book greatly contributes to the limited literature on theoretical discourses and practices on indigenous knowledge of livestock herding communities in the Horn of Africa. It discusses knowledge heritage and sovereignty through the presentation of valid empirical evidence, and its subsequent relevance in nurturing sustainability of knowledge systems to enhance lives of pastoralists in Africa and beyond.’ Samuel Tefera PhD, Assistant Professor and Asian Desk Coordinator at the Centre for African and Oriental Studies, Associate Dean for Research and Technology Transfer, College of Social Sciences, Addis Ababa University ‘The author has worked with our Beni-Amer pastoral communities in Eastern Sudan and Western Eritrea for over 30 years and this book is the first of its kind in documenting our practices, knowledge systems, heritage and way of life.’ Mustafa Faid and Mohamed Ali, Leaders of the of the Pastoral and Environmental Association Kassala State (PEAKS) ‘A riveting and rare book! Zeremarian Fre guides you along the sandy [dusty] tracks and grassy pastures that the Beni-Amer and their herds have been softly tracing over time all through the Horn of Africa. One of the virtues of the book is that it illustrates vividly and in clear language how their continuous self-built endogenous knowledge on agro-pastoral life is not only at the core of their survival and the survival of their herds, but more importantly a powerful weapon in facing and resisting multiple aggressions . . . Ground-breaking and a huge achievement.’ Yves Cabannes, Emeritus Professor of Development Planning,, The Bartlett Development Planning Unit, UCL ‘The book underlines the importance of enriching and utilizing the unrecognized, yet valuable scientific knowledge and practices that are deeply rooted in pastoral traditional expertise about their own environment and breeding practices. It is an important publication that reflects Dr Fre’s expertise and long term research in the region and thus, it is a significant addition to the African library.’ Hala Alkarib, Director of the Strategic Initiative for Women in the Horn of Africa (SIHA) ‘This fascinating book not only gives a unique insight into the knowledge and practice of pastoralists in the Horn of Africa from the author’s first-hand experience, it also provides an incisive critique of the multiple dimensions of knowledge, paying tribute to the sovereignty of indigenous knowledge. It has a timely relevance for global sustainability that will appeal to a wider readership.’ Nicole Kenton, International Development Consultant, former long serving senior staff member of the International Institute for Environment and Development (IIED) ‘The book covers several intertwined issues relevant to contemporary development policy and practice. It goes beyond the rural-urban and peasant–nomadic livelihoods dichotomy by shedding more light on the inter-linkages within the multiple livelihood systems within the Horn of Africa and globally. A rich evidence-based resource for academics, development partners and social movements for promoting and designing state policies that embrace pastoralist aspirations.’ Bereket Tsegay MA, PhD candidate, Pastoral and Environmental Network in the Horn of Africa (PENHA) ‘Dr Zeremariam Fre has done a wonderful job of placing at the centre of this book the Beni-Amer pastoralists, the world they inhabit and the knowledge they use to navigate and thrive in it. The lessons contained in this book go beyond pastoralism; it is a must read for anyone serious about understanding the importance of located knowledge in the innovation and development process.’ Yusuf Dirie, PENHA Research Fellow and PhD researcher at the University of Sussex
