Tackling Greenhouse Gases in Dairy Farming: The Big Three Emissions You Need to Know
When discussing GHG emissions in dairy production, three key offenders come to mind: carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Each of these gases has distinct origins and effects.
Carbon dioxide is predominantly released by agricultural equipment such as tractors, milking machines, and other fossil fuel-powered gear. However, methane is more challenging to deal with. It is mainly derived from enteric fermentation, a natural digestive process in cows that produces methane as a byproduct. Finally, nitrous oxide is typically made via manure management and fertilizer application. Despite its modest volume, nitrous oxide has a global warming potential 265 times more significant than CO2 over 100 years, making it an essential target for emission reduction efforts [EPA, 2021].
It takes work to measure these emissions accurately. Direct measurement often necessitates using expensive and complex equipment, such as gas analyzers and sensors, which may be costly. Furthermore, to give reliable data, these systems must remain active 24 hours a day, seven days a week, resulting in massive financial and time expenses. Direct measurement often requires specialized expertise, which may need extra training or hiring specialists, adding another layer of complexity.
Here’s where mathematical models come in. Models such as the Integrated Farm System Model (IFSM) and COMET-Farm may be used to estimate GHG emissions depending on different farm factors. While these models are helpful, they often have drawbacks. Many need to be more user-friendly and require significant data inputs, making them difficult to set up and comprehend. Others are highly research-oriented, with complicated formulae that may not apply to real agricultural choices. Furthermore, even the most complex models cannot capture each farm’s distinct traits, resulting in significant mistakes or oversimplifications in their projections.
While other models provide valuable insights, their complexity and lack of accessibility can limit their practical use for the average dairy farmer. This is where user-friendly technologies like DairyPrint shine, offering vital information without overwhelming you with complexity, making you feel at ease and comfortable with the technology.

How DairyPrint Works: Breaking Down the Model Components
The DairyPrint model aims to simplify the estimation of greenhouse gas (GHG) emissions on dairy farms. It achieves this by breaking down the process into three major modules: the herd, manure, and crop modules. Each of these modules is designed to be user-friendly, providing a simple but comprehensive tool that even the busiest dairy farmer can easily use.
- The Herd Module
The herd module monitors your cows’ numbers, feed consumption, and milk output. It stimulates herd dynamics monthly, considering elements such as cow count, calving interval, and culling rate. The model uses this information to predict crucial variables such as milk production, feed consumption, manure output, and digestion-related methane emissions. This helps farmers understand how changes in herd management affect total GHG emissions. - The Manure Module
The manure module focuses on handling and managing manure, a substantial source of GHG emissions on dairy farms. It estimates emissions depending on manure management practices, local meteorological data, and facility type. For example, it calculates methane emissions from manure storage and ammonia emissions from manure applied to fields. This session demonstrates how alternative manure management strategies, such as adjusting the frequency of dung pond emptying, may minimize emissions. - The Crop Module
The agriculture module examines greenhouse gas emissions associated with crop cultivation, including using manure as fertilizer. It estimates the emissions from applying manure, chemical fertilizers, and limestone to fields. Furthermore, it calculates the nutrient balance to guarantee crops get the proper quantity of nutrients without oversupply, which causes GHG emissions. The crop module demonstrates how farm inputs and outputs affect total GHG emissions by including various agricultural methods.
The DairyPrint model integrates herd, manure, and crop module data to provide a complete perspective of a farm’s GHG emissions. This simple tool enables you to make educated choices to promote sustainability and reduce carbon impact.
Simulation Insights: Uncovering DairyPrint’s Potential Through 32 Unique Scenarios
According to the Journal of Dairy Science, researchers developed 32 simulation scenarios to demonstrate the capabilities of the DairyPrint model. Each scenario used various nutritional formulas, bedding materials, and manure management approaches. We hoped that by running these simulations, we would provide crucial insights that would allow farmers to fine-tune their methods to decrease greenhouse gas emissions. Importantly, this study used simulations based on existing data and established models, not unique experimental research.
Across the 32 scenarios, the average GHG emission was 0.811 kgCO2eq/kg of milk, ranging from 0.644 to 1.082 kgCO2eq/kg. The scenario with the lowest emissions (0.644 kgCO2eq/kg) included:
- A lower NDF-ADF level in the diet.
- Incorporation of the 3-NOP dietary addition.
- Use of sand for bedding.
- Implementation of a biodigester plus solid-liquid separator (Biod + SL).
- Manure pond emptying in both Fall and Spring.
Conversely, the highest GHG emissions (1.082 kgCO2eq/kg) resulted from:
- A higher level of NDF-ADF is present in the diet.
- No incorporation of 3-NOP.
- Use of sawdust as bedding.
- No application of Biod + SL.
- Manure pond emptying only in Fall.
Key findings revealed that incorporating 3-NOP into lactating cows‘ diets significantly reduced enteric methane (CH4) emissions by approximately 24% (from 190 to 147 t/year), highlighting its potential in dietary adjustments. Lower dietary NDF-ADF levels demonstrated a modest 3% reduction in CH4 emissions (65 vs 66 t/year). Furthermore, enhancing bedding choice was notable—switching from sawdust to sand lowered manure storage CH4 emissions by 23% (74 to 57 t/year).
Manure management practices also played a crucial role. Emptying manure ponds biannually resulted in a significant 68% reduction in CH4 emissions from storage (99 to 32 t/year). Incorporating Biod + SL systems proved remarkably effective, cutting CH4 emissions by 59% compared to traditional storage methods (93 to 38 t/year).
The DairyPrint model also addressed ammonia (NH3) and nitrous oxide (N2O) emissions. For instance, sand bedding over sawdust led to slightly lower NH3 emissions in manure storage but increased crop emissions, likely due to better mineralization rates. Additionally, while manure emptying schedules minimally impacted NH3 levels, a seasonal storage strategy moving from solely Fall to Fall and Spring showed variability in the NH3 emissions profile, demonstrating the importance of timing in emission control.
The conclusions are clear: small but strategic changes in diet, bedding materials, and manure management practices can significantly impact GHG emissions. DairyPrint provides a clear, practical path for farmers to assess and modify their practices, leading to more sustainable, impactful farming operations.
