Cows Trained to Use Toilets to Help with Reducing Greenhouse Gas Emissions
In a pioneering effort to mitigate the environmental impact of livestock farming, researchers in Germany have successfully trained cows to use toilets, potentially revolutionizing agricultural practices aimed at reducing greenhouse gas emissions.
The groundbreaking study, conducted by scientists at an undisclosed research facility in Germany, focused on minimizing the release of ammonia—a significant contributor to greenhouse gases—from cattle urine. Ammonia, while not a direct greenhouse gas, can lead to the formation of nitrous oxide when it interacts with soil, contributing substantially to global warming.

The experiment involved allocating specially designed “MooLoo” enclosures for the cows, where they were trained to urinate. Upon successful use of the MooLoo, the cows were rewarded with food, reinforcing the desired behavior.
Subsequently, the urine collected from these toilets was carefully treated to neutralize its ammonia content, thereby reducing its potential environmental impact.
Dr. Hans Schmidt, lead researcher of the study, highlighted the significance of the findings: “Livestock production, particularly from cattle, contributes significantly to ammonia emissions in agriculture, which in turn contributes to greenhouse gas emissions. By training cows to use toilets, we can effectively reduce the amount of ammonia released into the environment.”

During the experiment, which spanned several weeks, the research team successfully trained 11 out of 16 calves to use the toilets—a remarkable achievement indicating the feasibility of implementing such practices on real farms.
The cows were initially placed in the MooLoo enclosures where they learned to associate urination with a reward system before being transitioned to a regular pen.
“This study marks a critical step towards implementing sustainable farming practices,” noted Dr. Julia Becker, an environmental scientist not directly involved in the research. “Reducing ammonia emissions from cattle urine can have a tangible impact on mitigating climate change, given the significant role of nitrous oxide as a greenhouse gas.”
Livestock farming currently accounts for approximately half of all ammonia emissions from agriculture and about 10% of human-related greenhouse gas emissions globally.
The successful training of cows to use toilets represents a potential breakthrough in efforts to combat climate change through innovative agricultural methods.
Looking ahead, researchers are optimistic about the scalability of their approach. “The techniques we’ve developed are practical and can be adapted for use in real-world farming scenarios,” added Dr. Schmidt. “Our goal is to work with farmers to implement these practices and ultimately reduce the environmental footprint of livestock production.”
While further research and field trials are needed to refine and validate these findings, the study offers a promising glimpse into how behavioral training of livestock could play a pivotal role in achieving sustainability goals in agriculture.
As the global community continues to explore diverse strategies to combat climate change, the prospect of cows using toilets stands out as a novel and potentially impactful innovation in the quest for a greener future.
This article is based on a study conducted by researchers in Germany, aiming to reduce greenhouse gas emissions from cattle urine through behavioral training. The results suggest that training cows to use toilets could be a feasible strategy to mitigate ammonia emissions in livestock farming.
