Special Issue Information
Dear Colleagues,
Animal reproduction is a cornerstone of livestock production, with significant advancements driven by reproductive technologies and genetic regulation. Modern assisted reproductive techniques, such as in vitro fertilization (IVF), ovum pick-up (OPU), and multiple ovulation and embryo transfer (MOET), have become indispensable in breeding programs. These technologies, while varying in efficiency, have seen continuous improvements, particularly in oocyte collection and in vitro embryo production systems. The integration of molecular marker-assisted gene technology and the study of polygenic aggregation effects have further enhanced the precision and effectiveness of breeding strategies. Genomic selection, combined with these molecular tools, allows for the identification and selection of desirable traits at the genetic level, optimizing reproductive outcomes. On the genetic front, the regulation of animal reproduction has been profoundly influenced by advancements in epigenetics and omics technologies. Researchers have uncovered complex molecular mechanisms involving histone modifications, noncoding RNAs, and RNA methylation, which play critical roles in reproductive regulation. These insights not only improve livestock production efficiency but also address ethical and welfare concerns. The application of molecular marker-assisted gene technology enables the identification of key genes associated with reproductive traits, while the study of polygenic aggregation effects helps in understanding how multiple genes interact to influence reproductive performance. This knowledge is crucial for developing advanced breeding programs that can meet the increasing demands of animal production.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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-blind 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.
