Reviewer 1 Report
The following recommendations are made to the authors
In the materials and methods, it should better describe how the experiment was carried out.
How was the daily feeding of the bulls?
How many times a day?
How often were the rejections withdrawn?
How was the drinking water?
what were the weather conditions?
In lines 163 and 164 use a formula editor
The authors should improve the discussion, since in most of it they only compare results with those already published in other manuscripts.
Further observations are indicated in the manuscript.
The writing must be improved and reviewed by a native English speaker

Research concerns an important and novel by product utilisation issue of the beef production (feeding, afttening). The article is clear, and interesting.
In my opinion, the manuscript could be suitable for publication after revision, addressing the following comments:
Please check the color, type and size of the font used.
- in line 26 and line 106 red color
- the line spacing: in lines 28-31.

Please give us more information about methods including serum examination. Please define kit names, which were used for detection of antioxidant satus of young fattening bulls.
Results Discussion
Please clarify the relationship (coefficient of correlation) between serum parameters, antioxidant indices with performance results.
The conclusions are correct and based on the results that are provided.

Reviewer 3 Report
Abstract
Must be corrected there is no need for space between treatments
Introduction
The hypothesis of the work must be clearly presented
M&M's
Clearly present the experimental design of the study
Line 163-164: These lines should be formatted as the rest of the text
Discussion
I recommend that the discussion not be done on topics such as the current form, as it is understood that there is no relationship between the variables studied, since the blood parameters can help explain the performance and digestibility results
Conclusion.
It must be rewritten and present the main results of the study. In its present form it still presents part of the discussion in it.
