Effect of Dietary Vitamin E on Growth Performance, Immunity and Antioxidant Capacity in Male Jiangnan White Goslings from 1 to 28 d of Age

Round 1

Reviewer 1 Report

The manuscript entitled "Effect of dietary vitamin E on growth performance, immunity and antioxidant capacity in male Jiangnan white goslings from 1 to 28 d of age" investigated the effect of different levels of vitamin E on performance, antioxidant status and humoral immune response of Jiangnan white goslings. The results revealed the improvement potential of vitamin E to the studied parameters. The manuscript is well prepared except the results section. The English is not sufficient and needs to be improved. I have some remarks on the manuscript:

• My major concern is the statistical analysis. I contraindicate the use of LSD post-hoc test. This test does not control the occurrence of type I error, which makes the results found doubtful. I suggest that authors use Tukey's test.
• Line 59, the authors must be more precise in formulating their sentences and do more in-depth research. You are not the first to study the effect of vitamin E supplementation on geese. Please review, for example, but not limited to, the following articles:

• Line 101, add more information about the centrifuge such as model, city, country … etc.
• Presentation of results section is poor and needs to be improved.
• Lines 124-125, no significant differences among groups in which parameter? Rewrite the sentence.
• Remove Table 7 and merge it with Table 3, or at least keep the table numbering order within the manuscript.
• Line 146, not correct, no significant differences between 36 mg/kg group and 0, 12 and 24 mg/kg groups. You may mean 48 mg/kg group!
• Line 180, again not correct, the 48 mg/kg group was less than that of only the 0 mg/kg but not 12 mg/kg. You may mean 36 mg/kg group!
• Line 190, focus on geese and poultry rather than the human body.
