The present work had the objective of evaluating the thermal comfort by means of the Temperature and Humidity Index (ITU) inside a model of small scale poultry houses using different hedging strategies. The experiment was carried out at the Federal University of Santa Maria Cachoeira do Sul. The coverings used were: fiber cement (control), fiber cement + white paint + thermal blanket, fiber cement + white paint. The temperature and relative air humidity reading were performed inside each model and in the external area, with DTH 22 sensors controlled by Arduino, divided in four periods of summer 2017/2018. Compared to the external environment, the different coverages promoted a mean reduction of ITU from 84 to 76. Significant statistical differences between the different coverage were observed, in which the average ITU of the period of 77.31 observed in the control was reduced to 74.90 on the covers with white paint. Based on the conditions under which the study was conducted, it is recommended to cover asbestos cement + white paint to improve thermal comfort inside poultry houses.Downloads

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
In particular,
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
