Content of review 1, reviewed on April 26, 2021

The present study is clear and has enough data to be published as a full article research in Veterinary Medicine and Science. I have some suggestion to further improve the quality of the manuscript.
1- It is recommended that the abstract includes a clear aim of the study.
2- The name of commercial product used in the study is un clear, sometimes written as STIMULAN or STIMULANT, kindly correct.
3-where is the information about the commercial immunostimulant used, as well there are no information about the production company??
4-kindly find attached yellow-colored comments on the manuscript, try to fix it.
5-Ln.475: incomplete reference.
6- A very important message: the manuscript's language needs some serious revision. Please, consider assistance of an English language editing service
