Special Issue Information
Dear Colleagues,
Intensive biochemical processes occurring in the bodies of highly productive animals result in a significant increase in oxygen demand. The consequence of these transformations is the production of significant amounts of free oxygen radicals (FOR) and other reactive oxygen species (ROS). Under homeostasis conditions, reactive oxygen species are constantly inactivated by antioxidants of both endogenous and exogenous origin. An increase in the production of free radicals, a decrease in the amount of antioxidants, and a decrease in the activity of enzymatic systems responsible for the removal of ROS mean that they are not effectively eliminated from the body. The balance is disturbed, and pro-oxidant processes outweigh antioxidant processes, which is called oxidative stress. Farm animals are highly exposed to oxidative stress. The main factors inducing the formation of reactive oxygen species comprise the perinatal period, pregnancy, poor quality of the feed ration, high environmental temperatures, diseases, infections, and physical exertion. The long-term impact of oxidative stress is associated with damage to proteins, lipids, and DNA in the cells of the body. As a result, the general health status of animals is disturbed, production results (e.g., weight gain and feed utilization) and the quality of animal products deteriorate. Adding antioxidant substances to feed mixtures may be a type of prophylaxis, protecting against the adverse effects of free radicals.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
