  • Greenhouse Gas Emissions from Ruminant Supply Chains – a Global
    5. Discussion This section discusses the key drivers of variation in emissions from major process- es in the ruminant supply chain that contribute significantly to the carbon footprint of ruminant species, highlighting differences among species and world regions. The section also discusses some of the parameters and assumptions that could strongly influence the results. 5.1 METHANE EMISSIONS FROM ENTERIC FERMENTATION Regardless of the species, the largest source of GHG emissions in ruminant produc- tion is CH4, with more than 90 percent originating from enteric fermentation and the rest from manure. Globally, enteric fermentation from cattle, buffalo, and small ruminants contributes 2 448 million tonnes CO2-eq, of which 76 percent is emitted by cattle and 14 percent and 10 percent by buffalo and small ruminants, respec- tively. The production of enteric CH4 from ruminants is mainly affected by feed intake and feed quality which, in turn, defines the total energy and nutrient intake and consequently animal performance. Many of these factors are interrelated, some of which affect net emissions and others emission intensity. At animal level, net emissions are influenced by feed intake and digestibility, while emission intensity is a function of net emissions, yield per animal, health and genetics. At herd level, factors affecting net emissions are similar to those cited above, while emission intensity is determined by issues such as reproductive and mortality rates, herd structure, management, etc. The following sections discuss some of the important factors that drive the variation in enteric CH4. Productivity. Productivity is an important factor in explaining the variation of emissions among different production typologies.

Dietary interventions, management, and biotechnological strategies to reduce the environmental impacts and economic implications of enteric CH4 emissions are needed. While the use of biotechnological interventions and management strategies can be challenging on a routine basis, feed additive supple- mentation appears to be the most researched, developed, and ready to use strategy to mitigate enteric CH4 emissions. This paper discusses various recently developed feeding strategies to reduce enteric CH4 emissions in livestock. Additionally, the manuscript reviews various technologies developed for CH4 estimation since the accurate and reliable estimation of CH4 emissions can be a limiting step Citation: Prathap, P.; Chauhan, S.S.; in the development and adoption of any mitigation strategy.

It is known that from the agricultural sector, ruminant livestock (dairy, beef, goats, and sheep) substantially contributes to the increase in CH4 production through continuous natural rumen fermentation process. Methane emission is now the second contributor to global warming, which it has 23 times more influence than that of carbon dioxide (CO2). Many factors affect the amount of ruminant CH4 production, including level of feed intake, type and quality of feeds, energy consumption, animal size, growth rate, level of production, and environmental temperature. Methane also produced from manure of animals depending on the physical form of the faeces, the amount of digestible material, the climate, and the time they remained intact. The major part of methanogenesis in ruminants occurs in the large fermentative chamber, which is rumen. Ruminal digestion of feed by microorganisms, under anaerobic conditions, results in the production of acetate, propionate and butyrate (volatile fatty acids) which are used by the animal as energy source, and production of ruminal gases such as carbon dioxide (CO2) and CH4, which eliminated through eructation.

  • Ch4 Emissions from Enteric Fermentation
    Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories CH4 EMISSIONS FROM ENTERIC FERMENTATION ACKNOWLEDGEMENTS This paper was written by Michael J. Gibbs and David Conneely (ICF Incorporated), Don Johnson (Colorado State University), Keith R. Lasse (National Institute of Water and Atmospheric Research, New Zealand), and M. J. Ulyatt (New Zealand Pastoral Agriculture Research Institute). ABSTRACT Livestock are produced throughout the world, and are a significant source of global methane (CH4) emissions. The amount of methane emitted is driven primarily by the number of animals, the type of digestive system, and the type and amount of feed consumed. The Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC Guidelines) recommend that CH4 emissions from enteric fermentation be estimated by multiplying the number of animals for each animal type by an appropriate emissions factor. The IPCC Guidelines recommend two general methods to estimating emissions factors. The Tier 1 method involves using default emissions factors, while the Tier 2 method involves using country-specific information to calculate the emissions factors. The Tier 2 method is more accurate than the Tier 1 method because it incorporates country-specific information. The Tier 2 method is recommended to estimate methane emissions for countries with large cattle or sheep populations. The key challenge to using the Tier 2 method lies in data collection. Generally, collecting data for Tier 2 requires a high level of effort. Below is a description of the data needed for Tier 1 and Tier 2. Tier 1 To estimate emissions using Tier 1 method, data on the number of animals for each livestock group are needed.

(December 2009) Amy DeAnn Hagerman, B.S., Oklahoma State University; M.S., Texas A&M University Chair of Advisory Committee: Dr. Bruce A. McCarl Foreign animal disease can cause serious damage to the United States (US) agricultural sector and foot-and-mouth disease (FMD), in particular, poses a serious threat. FMD causes death and reduced fecundity in infected animals, as well as significant economic consequences. FMD damages can likely be reduced through implementing pre-planned response strategies. Empirical studies have evaluated the economic consequences of alternative strategies, but typically employ simplified models. This dissertation seeks to improve US preparedness for avoiding and/or responding to an animal disease outbreak by addressing three issues related to strategy assessment in the context of FMD: integrated multi region economic and epidemic evaluation, inclusion of risk, and information uncertainty.

THE EFFECT OF EARLY LIFE NUTRITION ON RUMEN MICROBIAL COMMUNITY DEVELOPMENT AND IMPACT ON LIFETIME PERFORMANCE IN RUMINANTS A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy In Veterinary Sciences At Massey University Palmerston North New Zealand Omar Cristobal Carballo 2019 Abstract Manipulation of the rumen microbiota in adult ruminants has been intended to improve animal performance and decrease greenhouse gas emissions, but results have only shown a short- or non-lasting effect after intervention. Changes in the ruminal microbiota during rumen development have recently shown promising results in the short-term. Therefore, the purpose of the present body of work was to determine how dietary management and chemical interventions, during rumen development, modify the ruminal microbial community composition, and whether these changes affect rumen fermentation and development, and consequently, performance in the young ruminants. The objectives of this thesis were to: (i) evaluate the impact of early weaning on rumen development and function in artificially-reared lambs; (ii) characterize the impact of early weaning in lambs on the rumen microbiota in the first 16 weeks of life and examine the relationships between rumen microbiota composition and rumen fermentation profiles, rumen development and blood metabolites; (iii) assess whether contrasting feeding regimes in the first 7 months of life lead to an imprint in the rumen microbial community structure, fermentation profiles and methane emissions in the rumen of calves; (iv) and evaluate the effect of methane inhibitors on the rumen microbial community composition, fermentation pathways, and gas emissions in calves.

  • Greenhouse Gas Emissions from Livestock and Poultry
    www.afabjournal.com Copyright © 2013 Agriculture, Food and Analytical Bacteriology REVIEW Greenhouse Gas Emissions from Livestock and Poultry C. S. Dunkley1 and K. D. Dunkley2 1Department of Poultry Science, University of Georgia, Tifton, GA 2School of Science and Math, Abraham Baldwin Agricultural College, Tifton, GA ABSTRACT In 2008 the Environmental Protection Agency (EPA) estimated that only 6.4% of U.S. greenhouse gas (GHG) emissions originated from agriculture. Of this amount, 53.5% comes from animal agriculture. Agri- cultural activities are the largest source of N2O emissions in the U.S. accounting for 69% of the total N2O emissions for 2009. In animal agriculture, the greatest contributor to methane emissions is enteric fermen- tation and manure management. Enteric fermentation is the most important source of methane in beef and dairy production, while most of the methane from poultry and swine production originates from manure. The main cause of agricultural nitrous oxide emissions is from the application of nitrogen fertilizers and animal manures. Application of nitrogenous fertilizers and cropping practices are estimated to cause 78% of total nitrous oxide emissions. Based on the life cycle assessment of beef cattle, 86.15% of the GHGs are emitted during the production stage, while 68.51% of emissions take place during the production of pork and 47.82% of GHG emissions occur during the production stage of broiler chickens. The majority of the emissions from the beef cattle production comes from enteric fermentation while manure management is the major source during swine production and propane use during broiler poultry production. Keywords: greenhouse gas, LCA, poultry emissions, beef emissions Agric.
