Special Issue Information

Dear Colleagues,

Reproductive success is a very important objective to ensure the evolution of animal species. In this sense, many interesting studies have been carried out to clarify various aspects of reproduction in the horse. Recent advances in the knowledge of biology, endocrinology, and biotechnology developed in mares have been key to improving efficiency. This Special Issue is focused on “Veterinary Endocrinology and Reproduction in the mare” and therefore welcomes novel research or insightful reviews on these aspects in this species.

Physiological control and hormonal synchronization of the estrous cycle is pivotal in guaranteeing fertilization and pregnancy. The ability to produce a viable foal is critical to the broodmare. The interaction and coordination between the ovary, placenta, and fetus guarantee the hormonal secretion necessary to achieve a successful pregnancy. Maternal–fetal interaction is mediated by the fetoplacental unit, the necessary interface for the production and secretion of these steroid hormones. In equine clinical practice, the evaluation of hormonal profiles during pregnancy is one of the main determinants of fetal and/or placental involvement. Consequently, progestogens and estrogens, among others, are useful in monitoring the health status of the placenta and fetal viability. Since placental and/or compromised pathologies or death lead to alterations in the profiles of these hormones, hormonal diagnosis allows the timing and detection of early pathological conditions to establish the appropriate treatment for the maintenance of pregnancy and to reduce the loss of foals.

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).

Several studies have demonstrated that in woman the sex hormones such as estrogen (E2) and progesterone (P4) influence iron (Fe) regulation, contributing to variations in Fe parameters along the menstrual cycle. These mechanisms based on the regulation of hepcidin (Hepc) which limits Fe availability during the cycle, remain poorly characterized in healthy mares. The objective of this study was to establish the relationship between Hepc, Fe, ferritin (Ferr), and the primary ovarian hormones E2 and P4 in cycling Purebred Spanish mares. Blood samples were taken from 31 Purebred Spanish mares day −5, on day 0, day +5 and day +16 of the cycle. Fe and Ferr significantly increased and Hepc decreased during pre- and ovulatory periods. The secretion peak of estradiol-17β (E2) was reached on day 0 and progesterone (P4) between days +5 and +16. Fe and Ferr were positively correlated (r = 0.57). Fe and Ferr were negatively correlated with Hepc (r = −0.72 and r = −0.02, respectively). E2 and P4 were negatively and positively correlated with Hepc (r = −0.753 and r = 0.54, respectively). In cycling Purebred Spanish mares there is a measurable relationship between steroid hormones and systemic Fe metabolism. Estrogenic dominance in the pre- and ovulatory period allows for a more effective iron status, mediated by hepcidin inhibition. However, P4 during the luteal phase substantially reduces serum Fe and iron stores, possibly related to Hepc stimulation. Future research is required to clarify the relationship between steroid hormones and iron metabolism at the molecular level in equids. Full article
