On-farm methane measurements during milking correlate with total methane production by individual dairy cows

P.C. Garnsworthy, J. Craigon, J.H. Hernandez-Medrano, N. Saunders
2012 Journal of Dairy Science  
The objective of this study was to investigate whether measurement of methane emissions by individual dairy cows during milking could provide a useful technique for monitoring on-farm methane emissions  ...  It was concluded that, with further validation, on-farm monitoring of methane emission rate during milking could provide a low-cost reliable method to estimate daily methane output by individual dairy  ...  of initial data and prototype development for the on-farm technique.  ...

Effects of Two Manure Additives on Methane Emissions from Dairy Manure

Jessie Cluett, Andrew C. VanderZaag, Hambaliou Baldé, Sean McGinn, Earl Jenson, Alexander C. Hayes, Sylvanus Ekwe
2020 Animals  
Liquid manure is a significant source of methane (CH4), a greenhouse gas. Many livestock farms use manure additives for practical and agronomic purposes, but the effect on CH4 emissions is unknown.  ...  The results suggest that farms using these additives are likely to have normal CH4 emissions from stored manure.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...

An Approach for Measuring Methane Emissions from Whole Farms

S. M. McGinn, T. K. Flesch, L. A. Harper, K. A. Beauchemin
2006 Journal of Environmental Quality  
Our study was conducted at a commercial dairy farm in southern Alberta, Canada (total of 321 cattle, including 152 lactating dairy cows).  ...  Estimates of enteric methane (CH 4 ) emissions from ruminants are typically measured by confining animals in large chambers, using head hoods or masks, or by a ratiometric technique involving sampling  ...  ACKNOWLEDGMENTS This study was funded by National Carbon and Greenhouse Gas Emission Accounting System (NCGAVS) and the Canadian Foundation for Climate and Atmospheric Sciences (CFCAS).  ...

Effects of SOP Lagoon Additive on Gaseous Emissions from Stored Liquid Dairy Manure

Carlyn B. Peterson, Hamed M. El Mashad, Yongjing Zhao, Yuee Pan, Frank M. Mitloehner
2020 Sustainability  
The present research aimed at testing the ability of the commercial additive "SOP LAGOON" to reduce emissions of GHGs (i.e., carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)), as well as ammonia  ...  There are several technologies to reduce emissions on animal farms including manure additives; however, few have been proven effective and easy to apply to dairy lagoon systems.  ...  Conflicts of Interest: The sponsor played no role in the execution and interpretation of the data and preparation of the present manuscript. The authors declare no conflict of interest.  ...

Components of Dairy Manure Management Systems

H.H. Van Horn, A.C. Wilkie, W.J. Powers, R.A. Nordstedt
1994 Journal of Dairy Science  
Methane Emissions Methane emissions from animal production systems do not present an odor control problem because methane is odorless.  ...  Thus, manure nutrients are needed at some locations even though these nutrients are in surplus on some dairy farms.  ...

2019 Environment International  
For the first time, we present comprehensive LCA results for multiple environmental burdens based on a large panel dataset for commercial dairy and suckler-beef farms.  ...  Dairy-beef was much more efficient than beef produced on suckler-beef farms in terms of footprints per unit of beef output.  ...  Special thanks to three anonymous reviewers for their very constructive recommendations in particular the suggestion of modelling sensitivity to the beef:milk ratio and regional effects.  ...

Since 2009, it has also been used to measure the methane (CH4) concentration in the breath of cattle, sheep, and goats to quantify their CH4 emissions.  ...  These aspects, such as the distance to the animal or the activity of the animals, should be fixed for all measurements of an experiment, and if this is not possible, they should at least be documented  ...  The LMD shows the data in real time on its display and optionally issues an acoustic and visual alarm if a certain threshold is exceeded.  ...
