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
Ruminants contribute significantly to human food security. However, the production of ruminants contributes to greenhouse gas (GHG) emissions that are responsible for climate change. GHGs such as methane, carbon dioxide, and nitrous oxide are produced from different processes of ruminant production. Ruminant enteric methane is a substantial component of methane produced by agriculture. This book presents novel and established methods in quantifying and reducing enteric methane emission from ruminants in different production systems. The book covers different types of ruminants including cattle, sheep, and goats. The chapters are contributed by scientists and authors from different parts of the world, demonstrating the importance of this problem and the universal drive for immediate and sustainable solutions. Although, biologically speaking, the production of enteric methane cannot be reduced to zero, high emissions are an indicator of inefficient digestion of feed in the rumen and low utilisation of feed energy. By presenting research that could lead to robust and yet practical quantification methods and mitigation strategies, this book not only contributes to the discourse and new knowledge on the magnitude of the problem but also brings forward potential solutions in different livestock production systems.

Book Description
Recent IPCC reports have highlighted the environmental impact of livestock production as a major source of non-CO2 emissions: methane (CH4), nitrous oxide (N2O) and ammonia (NH3). The livestock sector must react to these reports and develop or implement methods that can reduce greenhouse (GHG) emissions from livestock production. Reducing greenhouse gas emissions from livestock production provides authoritative reviews on measuring GHG emissions from livestock as well as the range of methods that can be applied to reduce emissions, ranging from breeding to animal health and manure management. The collection also reviews nutritional approaches such as improving forage quality and the use of plant bioactive compounds and other feed supplements to limit emissions by modifying the rumen environment. Drawing in an international range of expert authors, Reducing greenhouse gas emissions from livestock production summarises what we can do to make livestock production more sustainable and viable for the future. It will be a major reference for the livestock (particularly dairy) science research community, environmental scientists, government and other agencies tackling the challenge of climate change, as well as companies involved in livestock production and processing of dairy and meat products.

Book Description
Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

Book Description
Seminar paper from the year 2017 in the subject Veterinary medicine, , course: Seminar, language: English, abstract: The objective of this review is to point out that the global dialog on reducing greenhouse gas emissions in animal agriculture has, thus far, not adequately considered animal welfare in proposed climate change mitigation strategies. Many suggested approaches for reducing emissions, most of which could generally be described as calls for the intensification of production, can have substantial effects on the animals. Climate change is seen as a major threat to the survival of many species, ecosystems and the sustainability of livestock production systems in many parts of the world. As per estimates, about 12.5% of total emissions of greenhouse gases are related to livestock production .This contribution is even higher (18%) when the deforestation related to the expansion of livestock production area is also considered to meet the growing demand of animal products. Livestock contributes about 9% of total carbon dioxide production emissions, 37% of methane, and 64% of nitrous oxide emissions throughout production process. There is an urgent need to integrate these other sustainability measures into GHG mitigation assessments. Mitigation in reducing emissions can be achieved in different ways related to animal feeding and management, manure collection, storage, improved animal waste management through energy (biogas) recovery, and management of crops fed to the livestock by bringing more drastic changes of the whole production system. A number of techniques exist to reduce methane emissions from enteric fermentation from ruminants. Improving the genetic potential of animals through planned cross-breeding or selection within a breed, and achieving this genetic potential through proper nutrition and improvements in reproductive efficiency, animal health and reproductive lifespan are effective and recommended approaches for improving animal productivity and reducing GHG emissions per unit of product. There are several factors which need to be considered for selection of best options for methane emission reduction: these include climate, economic, technical and material resources, existing manure management practices, regulatory requirements etc. Generally the methane mitigation strategies can be grouped under three broader headings viz., manage mental, nutritional and advanced biotechnological strategies.
