Advances in Veterinary Reproduction and Embryonic Development

Dear Colleagues,

In recent years, female livestock infertility, triggered by ovulation disorders and abnormal termination of early pregnancy, has seriously impacted the effective breeding of livestock. Therefore, according to the requirements of Veterinary Sciences, I hope to organize a Special Issue mainly focused on ovulation disorders and the abnormal termination of early pregnancy in large livestock, especially in cattle and pigs. I hope to summarize the advancements in reproductive disorders in livestock and therapeutic mechanisms with research from experts in related fields.

This Special Issue will contain two parts. First, it will collect some of the latest research on ovulation-regulation mechanisms in cattle and pigs. In addition, it will also invite clinical treatment experts to provide reviews on the treatment principles and methods for ovulation disorders, as well as treatment cases and treatment reports. Specifically, JIVET (juvenile in vitro embryo transfer) has recently been a popular technology in China, but the superovulating follicles of lambs or calves cannot mature in vivo and can only be cultured in vitro. Attempts to understand how we can promote the effective ovulation of superovulating follicles in vivo would be a very attractive and indispensable topic in this Special Issue, and I hope to publish research on this.

Secondly, this Special Issue will focus on the phenomenon of the abnormal termination of early pregnancy. In this field, we are mainly concerned with the phenomenon in gene-edited and cloned animals. Therefore, I hope to receive research in this field as well as comprehensive reviews. Review articles should comprehensively elaborate the molecular mechanism causing the abnormal termination of early pregnancy in the cloning process of gene-edited animals and put forward suggestions for improvement. In addition to the topics mentioned above, some infectious diseases (genetic diseases) and nutritional abnormalities can also lead to the termination of early embryo development and, of course, some unmentioned reasons can also lead to early pregnancy termination. I hope to publish related articles that actively participate in this discussion.

I hope that this Special Issue will further stimulate collaboration between scientists engaged in all aspects of reproductive disorders in livestock and therapeutic mechanisms.

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. Veterinary Sciences is an international peer-reviewed open access monthly journal published by MDPI.
