Submitted manuscripts to the Egyptian Journal of Nutrition and Feeds must be original works of the author(s). Authors are advised to check for plagiarism using a known standard program before sending final corrected articles to avoid rejection when checked later on by EJNF. The manuscript should not be published previously or submitted to another journal at the same time. Data fabrication and falsification are strongly unaccepted and insert authors in the blacklist. All the authors must have a fair contribution to the research conducted and submitted to us. EJNF requires all authors to follow the International ethical standards as prescribed by the Committee on Publication Ethics (COPE).
