Line 3: we added “growth performance”

Line 12-19: we rewrote the paragraph

Line 24: we added M&M and some results

Line 29: we reworded the sentence

Line 35-42: we accepted your suggestions

Line 44-46: we rewrote the sentence

Conclusion: we rephrased the paragraph, but we consider relevant the comments on n6/n3 ratio and the oregano’s antioxidant activity.

Reviewer 2 Report

General opinion
The authors undertook research on the effect of dietary supplementation with extruded linseed and oregano on the carcass composition and meat quality of Jonika's kids. The present manuscript enriches the knowledge about the possibilities of shaping the quality of kid meat through nutrition. Modification of the diet was proposed, which leads to lower values of the n-6 / n-3, atherogenic and thrombogenic indices, which are correlated with diseases, especially of the circulatory system. At the same time, no negative influence of the proposed diet on fat oxidation and meat color was demonstrated.
The scope of the research carried out is well planned. The authors adequately substantiated the need for these studies. The materials and methods are well described. The discussion of the results is properly prepared. I believe that the manuscript in its present form can be accepted for publication.

Dear reviewer thank-you very much for your consideration. We have change some parts in the text, we hope that you will continue to like it.

Reviewer 3 Report

Review of the manuscript entitled “Extruded linseed and oregano dietary supplementation: effects on Carcass Composition and Meat Quality of Jonica kids”

The manuscript is interesting, however, it needs changes before acceptance. I am not a native English speaker, so I don’t usually suggest changes. However, there is some terminology and some sentences that could need English editing.

Abstract: reduce the introduction to include the most relevant results obtained in the experiment. Modify the conclusion as some sentences are repeated exactly in the discussion of the manuscript.

Introduction and material and methods sections

Several parts of both sections are exactly the same as those presented in the paper of Scarpa et al. (2021) published in Animals as they use the same diets during the same amount of time but in lambs. The present manuscript could refer to that paper to avoid plagiarism.

Tables 1 and 2 are already presented in Scarpa et al. (2021), with minor differences in Table 2

The introduction should be modified considering that these diets have been tested in lambs

Results

Delete the results in the text that have been presented in Tables. See the document

Discussion

The discussion should be improved as there are many interesting effects that have not been discussed.

Some sentences of the discussion are exactly the same in the abstract. Modify.

Line 12-19: we reduced the introduction

Line 24-29: we added the results

Introduction: Our trial on lambs and kids were contemporary, both part of an experimental protocol for the conservation of native species. Due to an internal timing was written before lambs work and now that on kids.

Line 58-83: we rephrased the paragraph as requested

Line 94: we added “homogeneous regarding age (20 ± 2 days old) and initial live weight (6.72 ± 1.22 kg)

 

Line 110: we change the text

 

Table 2: we think the table is necessary to avoid readers looking for another article

Line 126: we change the word

Line 129: we reworded the sentence

Line 145-155: we change the text as request

Line 156: we corrected the sentence

Line 159: without film

Line 164-174: we change the text as request

Line 175. We change the measurement unit of FA

Table 3: we apologize for the mistake, we correct the date

Line 207-209: we reworded the sentences

Table 4: We apologize for the mistake, it’s the Carcass weight

meat cuts: we calculated the percentage of fat only on the cuts of leg and loin as reported in table 5

Line 217: in our study on lambs, oregano inclusion reduced significantly the fat into the leg and without significant value into the loin.

Line 229: we corrected the sentence

Line 231: we commented our results

Line 238: we reworded the sentences

Line 251: we change the reference

Table 6: WBS: we convert the values

t-bars values of 10 d seem similar to those measured on day 3, so we did not consider necessary to carry out the analysis of repeated tests.

Line 268: we think that chemical composition of kids meat had significant difference because the SEM of items were lower than the lambs one.

Line 279-283: we changed FA name and we comment the results

Line 289: we reworded the sentence

Line 295: we rephrased the paragraph. We added the influence of oregano; we compare results with the lambs work.

Line 307: we added the lambs results

Conclusion: we rephrased the paragraph.

Reviewer 4 Report

Dear gentlemen, we agree in publishing the work but we think it is suitable the
following revisions:
Line 178 – define the equation terms;
Line 311 – Table 8, define UFA, A.I, and T.I.
In the text, use LO or L+O.

Thank-you for your kindly suggestions, we corrected all the revisions, you can find our correction in green

Line 178 – define the equation terms; done
Line 311 – Table 8, define UFA, A.I, and T.I. done
In the text, use LO or L+O. L+O is the name of experimental group in our study, in other papers the similar group is called LO, so we reported this acronim
