Reviewer 2 Report

Comments and Suggestions for Authors

This study provides valuable insights into the methane emissions from Peruvian dairy cattle, which is a significant contribution to the field of agricultural greenhouse gas emissions. The use of IPCC Tier II methodology adds credibility to findings. However, I have some concerns and a few suggestions that could enhance the clarity and impact of the current work.

1. Clarity in Abstract: The abstract could benefit from a more structured approach. Consider separating the objectives, methods, results, and conclusions into distinct paragraphs to improve readability.

2. Data Presentation: While the data collection from multiple regions is commendable, it might be helpful to include a brief discussion on the representativeness of these regions in terms of the national dairy farming landscape.

3. Methodological Considerations: It would be beneficial to provide more details on how the feeding types were defined and how the data were aggregated to ensure the methodology is transparent and reproducible.

4. Uncertainty Analysis: The uncertainty ranges for different animal categories are an important aspect of your study. It would be valuable to discuss potential sources of this uncertainty and how it might affect the applicability of your findings in policy development.

5. Comparison with Global Data: If possible, comparing your results with global or regional averages could provide context and highlight the uniqueness of the Peruvian situation.

6. Policy Implications: While you mention the potential for policy development, a more detailed discussion on how these emission factors could inform specific policy measures would be beneficial.

7. Figures and Tables: Ensure that all figures and tables are clear, well-captioned, and referenced in the text. This will help readers to easily locate and understand the data presented.

8. Conclusion Enhancement: The conclusion could be strengthened by summarizing the key findings and their implications more succinctly and emphasizing the novelty of your research in the context of existing literature.

Overall, this study presents interesting and potentially impactful results. With some refinements, it could make a strong contribution to the literature on agricultural emissions and policy development. Good luck!
