Book Description
To answer the above question the present studies were directed at: 1. Determining efficiency of conversion of protein in forages to milk proteins in cows grazed for short periods and fed for maximun milk production. 2. Studying the effect of the methods of handling and feeding recommended forage crops upon the level and efficiency of milk production and productivity of forage producing land. 3. Measuring the presinstency of the forage species managed under rotational-strip grazing system. 4. Conducting digestion trials to measure the value of green forage as well as stored forage. 5. Developing grazing/feeding systems adaptable to conditions of increasing herd size and increasing productivity of dairy cows.

Book Description
"This book contains a compilation of offered papers presented at the main congress of the XX International Grassland Congress held in University College Dublin, Ireland from 26 June to 1 July, 2005. It is complemented by six other books arising from the XX IGC as listed on the back cover: the book of invited papers from the main congress and five books containing the proceedings of five satellite workshops held immediately after the main congress at locations in the UK and Ireland (Aberystwyth, Belfast, Cork, Glasgow and Oxford). The workshops were designed to facilitate more in-depth presentations and discussions on more specialised topics of worldwide significance. The main congress brought together scientists from many disciplines, policy makers, consultants and producers involved directly in grass production and utilisation, as well as people in associated industries. They discussed issues around the theme of the congress, Grasslands : a Global Resource. The congress programme was organised around three main thematic areas: Efficient Production from Grassland Grassland and the Environment Delivering the Benefits from Grassland"

Book Description
The INRA Feeding System for Ruminants has been renewed to better address emerging challenges for animal nutrition: prevision of productive responses, product quality, animal health and emissions to the environment, in a larger extent of breeding contexts. The new system is mainly built from meta-analyses of large data bases, and modelling. The dietary supply model accounts for digestive interactions and flows of individual nutrients, so that feed values depend on the final ration. Animal requirements account for variability in metabolic efficiency. Various productive and non-productive animal responses to diets are quantified. This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas. The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins. Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes. Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.

Book Description
Managing Healthy Livestock Production and Consumption is a highly interdisciplinary resource based on scientific and empirical evidence. It is illustrated with best practices of low-input livestock systems from different continents and offers predictive modelling alternatives for a more resilient future. By addressing gaps of knowledge and presenting scientific perspective studies of livestock's impact on the environment and the global food supply up to 2050, this book is useful for those advocating for sustainable food systems. Existing evidence of the effects of livestock production on food quality and nutrition is reviewed. Livestock production and consumption is a highly diverse topic where current publications only include/focus a single aspect of the issues, for example, greenhouse gas emissions or health impacts, leading to unilateral decisions such as refraining from meat consumption. However, animals are necessary to soil fertility and ecosystems balance and a more realistic resource is necessary for researchers, scientists, and policy makers. This book clarifies perceptions by presenting sound scientific evidence across livestock landscapes for the scientific community to better appreciate the ecological web of life and the social web of community related to livestock production. An edited work written by globally diverse scientists and practitioners, including field workers, technicians, and policy makers, this is a valuable resource for researchers, teachers, and development agents working in the area of sustainable livestock production and consumption of animal source foods. National, international organizations, policy makers, and donors interested in sustainable development of the livestock sector will also find the information here practical and applicable. - Describes the public-health impacts of sustainable diets and livestock products - Presents the impacts of livestock production on the environment and food supply - Explores future scenarios (up to 2050) of low input livestock systems - Includes current case studies of low input livestock systems that offer potential for scaling-up and replication for sustainable livestock futures
