Special Issue Information

Dear Colleagues,

Reproductive aspects in livestock are complex, as the line between increased productivity and the onset of reproductive complications is often thin. To mention just a few examples, high embryonic death in pigs or placental retention in dairy cattle are reproductive disorders that largely depend on production characteristics. This Special Issue aims to collect original articles and reviews that broadly address the physiology and pathology of reproduction in production animals, including experimental models and non-conventional species.

Knowledge about animal reproduction increases every day. The development of new technologies has generated important advances in the normal reproductive biology and pathology of reproduction. The production demand favors the development of alterations and abnormal situations that do not appear in wild animals. Currently, there is also a demand for successful production to not forget animal welfare. Knowing the basic aspects of reproduction in the different species and breeds that are used for productive purposes is essential to improving production, while respecting the species’ characteristics to maintain welfare conditions. The reproductive system is one of the organic systems with the greatest interspecific variation, even between related species; for example, there are variations in the characteristics of the cycle, in the annexed glands in the male, in gestation and placenta, in the volume and characteristics of the ejaculate, etc. This Special Issue aims to collect articles and reviews that present results or gather knowledge on various aspects of reproduction both under normal and altered conditions. The concept of livestock is considered in a broad sense, and works on non-conventional animal production and experimental models generated to analyze reproductive aspects of livestock will be accepted.

This Special Issue welcomes original research articles and reviews. Research areas may include (but not limited to) the following:

The biology and pathology of the reproductive cycle in domestic animals (or in other species used for production);
Gametogenesis;
The morphology, physiology, biochemistry, and pathology of reproductive organs;
The morphology, physiology, and biochemistry of gametas;
The pathology of reproductive systems in males and females;
Experimental models applied to livestock reproduction and the pathology of reproduction;
Fertilization, embryo development, implantation, placentation, gestation, and partum in normal and pathological conditions;
Stress and reproduction;
Reproduction and biotechnology;
Reproduction in non-conventional animal’s productions;
The immunology of reproduction.

We look forward to receiving your contributions.

South American camelids inhabit high-altitude environments characterized by hypoxia, influencing embryonic, fetal, and placental development. This study examined the term placenta morphology of alpacas (Vicugna pacos, N = 12) and the immunoexpression of antioxidant selenoproteins (SP). We hypothesize that the placenta of alpacas, adapted to high altitudes, has characteristics with other species also adapted to altitude. Placentas were paraffin-embedded, sectioned (3–5 µm), stained with hematoxylin–eosin (H&E), Masson’s trichrome, and picrosirius red, and analyzed via light and polarized light microscopy. The chorion showed simple cuboidal epithelium with binucleated cells, a subepithelial mesenchyme rich in blood capillaries (area: 124.90 ± 9.82 µm2), and type III collagen fibers. The chorionic villi measured 2740.22 ± 132.75 µm. The allantois contained a simple columnar epithelium and mesenchyme with type I collagen fibers. Immunohistochemistry localized SP-N, SP-P, Dio-3, and GPx-3 in the blood capillaries and mesenchymal tissue of the chorion but not in the allantois. These findings were compared to human and sheep placentas from different altitudes due to a lack of camelid data at low levels. The morphological features resembled adaptations to hypoxia observed in other species. This preliminary study suggests a potential role for selenoproteins in hypoxia adaptation, providing a basis for future functional studies. Full article

The aim of this study was to identify genetic variants and pathways associated with the total number of piglets born and to investigate the potential negative consequences of the intensive selection for reproductive traits, particularly the formation of bumps on the legs of pigs. We used genome-wide association analysis and methods for identifying selection signatures. As a result, 47 SNPs were identified, localized in genes that play a significant role during sow pregnancy. These genes are involved in follicle growth and development (SGC), early embryonic development (CCDC3, LRRC8C, LRFN3, TNFRSF19), endometrial receptivity and implantation (NEBL), placentation, and embryonic development (ESRRG, GHRHR, TUSC3, NBAS). Several genes are associated with disorders of the nervous system and brain development (BCL11B, CDNF, ULK4, CC2D2A, KCNK2). Additionally, six SNPs are associated with the formation of bumps on the legs of pigs. These variants include intronic variants in the CCDC3, ULK4, and MINDY4 genes, as well as intergenic variants, regulatory region variants, and variants in the exons of non-coding transcripts. The results suggest important biological pathways and genetic variants associated with sow fertility and highlight the potential negative impacts on the health and physical condition of pigs.
