Round 1
Reviewer 1 Report
Although the manuscript deals with a well-known topic regarding the effects of supplemental cattle feed on pasture, it is nevertheless well written.
L 2-4: Please reword the title to make it shorter and more concise.
L 5-7: I think 17 authors on one article is too many. I recommend that some authors be moved to Acknowledgments.
L 38-44: The purpose of the present study is confusing. Please reword this paragraph. Please specify the working hypothesis of the research carried out.
L 124-130: Please specify the working hypothesis of the research carried out.
L 472-493: Please reword the Conclusions so that they are more concise and reflect the results of the study conducted. This chapter should contain a recommendation for the science and practice of cattle nutrition on pasture, as well as perspectives for future research.

Reviewer 2 Report
Line 58; the hypothesis, background, justification, and objective are detailed in the introduction section.
Line 132; as a suggestion and only if applicable or if the information is available, they could consider including proximate chemical analysis of the forages. In addition, generalized information on animal units (cows), age, sex, weight, body condition score, etc., should be included.
Line 208; the methodology is not clear, it was necessary to describe the number of data, clarify the type and description of the variables, and determine the sample number; Suggestion: include experimental design here, also include and describe statistical model.
Lines 331-355; include some cites. Additionally, it is interesting to explain the phenomenon of results and/or inferences.
Line 471; the conclusions were accurate and concrete but left out the aspect or description of the phenomenon of digestive physiology in ruminants.
Line 517; more than 85% of the cites are below the last 5 years. Please add more recent citations as appropriate in ruminant.

Reviewer 3 Report
Please include a sentence in the introduction section stating your hypothesis. Please refer to this sentence in the conclusion section.
The Discussion section is quite long and should give priority to the key solutions with support on literature documentation.
L474 + 490: "...affects the efficiency to some extent." What efficiency do you mean here? Please specify.
Figure 2: please increase letter size. In addition, the importance of this figure is questionable. It should be placed in the supplementary material
