Book Description
A major constraint to livestock production in developing countries is the scarcity and fluctuating quantity and quality of the year-round feed supply. Livestock are fed mainly on low quality agro-industrial by-products. The addition of foliage from tree leaves or supplementation with seed meals or even urea in the form of urea molasses multinutrient blocks can improve the utilization of low quality roughages mainly through the supply of nitrogen to rumen microbes. This publication presents results from the nutritional component of a project devoted to improving animal productivity and reproductive efficiency. This publication is an excellent reference source for researchers, students and extension workers and will help improve the utilization of feed resources and enhance animal productivity to meet the challenges imposed by the 'livestock revolution' taking place in developing countries.--Publisher's description.

Book Description
The authors and editors of this volume state that with the intensive growth of global industrialization and urbanization, the consumption of various resources and materials, such as energy, minerals, and even water, is increasing at an amazing speed, which poses great pressure on material resources. In addition, the massive utilization of materials has led to low efficiency, resulting in great wastes of resources as well as serious environmental pollutions and degradation, which has severely hindered the sustainable development of economy and society. In order to transit to sustainable development, it is necessary to improved resource efficiency, and circular economy and waste valorization are the best alternative ways for achieving this goal. This book aims to provide an in-depth description of circular economy and waste valorization, make assessments for circular economy and waste valorization in different regions and countries and determine the technological pathways and roadmap for achieving circular economy and waste valorization. More specifically: (1) Conceptions and Theories: Concepts and definitions of circular economy and waste valorization and their nexus and contributions to sustainable development. (2) Policy and Practice: Measurement and assessment of performance or sustainability for implementing circular economy and waste valorization. (3) Pathways and Prospects: Identification and prioritization of the barriers, strategies, technologies, and pathways for achieving circular economy and waste valorization. The book systematically and comprehensively introduces the definitions, concepts, framework and nexus of circular economy and waste valorization, analyzes and measures their performance and sustainability and provides the methods for investigating and prioritizing the barriers and strategies and determining the pathways and roadmap for their development.

Book Description
" ... At the Expert Consultation held at FAO headquarters in Rome in September 2011, participants called for a series of case studies to document existing practices that enhance animal welfare as well as farmers' incomes; currently, such studies are few and far between. This document presents a number of such studies and it is hoped that the information they contain will encourage researchers and agencies working in the area of animal welfare to initiate studies to capture the impact of any intervention on farmers' incomes - an area that has been neglected to date. It is also envisaged that these studies could pave the way for developing guidelines and policy options to promote sustainable animal feeding that enhances animal welfare, animal productivity, animal product quality and profitability."--Preface.

Book Description
The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded

Book Description
This book, inclusive of 19 chapters, provides discussions on the benefits and limitations of food-based approaches for the prevention and control of micronutrient malnutrition. Different chapters focus on specific relevant topics, including current developments in food-based approaches and their program applications, relevance of agricultural interventions to nutrition, impact of multi-sectoral programmes with food-based approaches components in alleviating undernutrition and micronutrient malnutrition, animal-source foods as a food-based approach to address nutrient deficiencies, aquaculture's role in improving food and nutrition security, benefits of vegetables and fruits in preventing and combating micronutrient malnutrition, benefits of food-based approaches for overcoming single specific micronutrient deficiencies, and food fortification. This book will be of great use to professionals interested in public health, human nutrition, micronutrient deficiency interventions, food and nutrition security policy interventions, and agricultural research.
