TL;DR: The porcine placenta is a key organ responsible for the exchange of nutrients, metabolites and respiratory gases between mother and fetuses as discussed by the authors, and placentation begins with implantation, which involves specialized cell adhesion and cell migration.

TL;DR: In this paper , the effects of early pregnancy on expression of PRL and PRLR in maternal immune organs in sheep were analyzed through quantitative real-time PCR, Western blot and immunohistochemistry.

TL;DR: The porcine placenta is a key organ responsible for the exchange of nutrients, metabolites and respiratory gases between mother and fetuses as discussed by the authors , and placentation begins with implantation, which involves specialized cell adhesion and cell migration.

TL;DR: In this paper , the role of insulin, glucagon, thyroid, thyroid and adrenal hormones in fetal metabolic processes is discussed and the metabolic interactions between these hormones and their role in the maturation of key tissues, such as the liver, skeletal muscle and adipose tissue.

TL;DR: Several comprehensive reviews of this subject have recently been published and the purpose of this short review is to consolidate current understanding of the relevance and biological significance of this emerging topic as discussed by the authors , which is a critical first step that will determine the validity of results.

TL;DR: In this paper, the role of insulin, glucagon, thyroid, thyroid and adrenal hormones in fetal metabolic processes is discussed and the metabolic interactions between these hormones and their role in the maturation of key tissues, such as the liver, skeletal muscle and adipose tissue.

TL;DR: In this paper , the authors discuss the physiological mechanisms of the adaptive response of poultry and the nutritional interventions to improve intestinal integrity during heat stress, including stress adaptation signaling pathways, blood flow, intestinal barrier permeability, epithelial cell proliferation, antioxidant status, microbiota composition, expression of heat shock proteins, inflammatory responses and energy metabolism.

TL;DR: It is concluded that M STN deficiency leads to increased IL-6 secretion in skeletal muscle and activates AMPK in adipocytes, thereby increasing the beige adipose tissue in MSTN-/- pigs.

TL;DR: In this article , the effects of prenatal and postnatal hyperthermia on the developmental outcomes of dairy cows, as well as the physiological and molecular mechanisms that may be responsible for the negative phenotypic consequences of heat stress that persist throughout the neonatal and adult periods and may have multigenerational implications.

TL;DR: In this article , the expression of melatonin receptors types 1A/B in bovine ovarian follicles was investigated by immunohistochemistry and the in vitro effects of Melatonin on secondary follicle development, antrum formation, viability, and expression of messenger ribonucleic acid (mRNA) for superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase-1 (GPX1) and peroxiredoxin 6 (PRDX6).

TL;DR: In this paper , the effect of a single administration of long-acting FSH on testicular blood perfusion as measured by pulsed-wave Doppler ultrasonography, testicular echotexture, and circulating testosterone (T), estradiol (E2), and nitric oxide (NO) in the plasma of rams in the non-breeding season was investigated.

TL;DR: The importance of the circadian clock in the regulation of lactation competence has been discussed in this paper , where it was shown that disruption of the clock can negatively affect mammary gland development and differentiation, alter maternal metabolism and impair milk production.

TL;DR: This article found that myostatin deficiency leads to increased IL-6 secretion in skeletal muscle and activation of AMP-activated protein kinase (AMPK) phosphorylation in adipose tissue, which subsequently activates peroxisome proliferator-activated receptor gamma coactivator 1α and the conversion of white adipocytes to beige in pigs.

TL;DR: The buck-to-buck effect was studied in seasonally anestrous goats with exposure to artificial long days (16 h of light per d) and untreated, sexually inactive (SI) goats as mentioned in this paper .

TL;DR: The importance of the circadian clock in the regulation of lactation competence has been discussed in this paper, where it was shown that disruption of the clock can negatively affect mammary gland development and differentiation, alter maternal metabolism and impair milk production.

TL;DR: In this paper , the authors found that the abundance of FGFR1c, FGFR2c and FGFR3c mRNA change according to follicular size, steroidogenic status, and days post-ovulation during growth of first-wave dominant follicles in Holstein cattle exhibiting regular estrous cycles.

TL;DR: In this article, the association of the Kisspeptin gene (Kiss1) with litter size in Indian goat breeds was investigated and it was shown that the mutation of Kiss1 gene has a significant role in reproductive processes in mammals.

TL;DR: In this article , the effects of lipopolysaccharide (LPS) endotoxin on follicular dynamics in a subacute inflammatory disease state were evaluated in cows with a select synch plus controlled internal drug release device (CIDR) follicular wave synchronization protocol.

TL;DR: In this paper, the effects of lipopolysaccharide (LPS) endotoxin on follicular dynamics in a subacute inflammatory disease state, 14 Angus heifers were blocked by weight and assigned to vehicle or LPS treated (n = 7) groups.

TL;DR: In this paper , the authors investigated the role of prostaglandin F2α and E2 in the process of parturition in the dog and found that no significant roles of estrogens for the initiating of the dog's pregnancy were demonstrated.

TL;DR: In this article , the effects of specific WNT ligands on FSH stimulated E2 production in the absence of endogenous WNT production in vitro were examined and the results suggest that both canonical and noncanonical WNT pathways activation is linked to FSH stimulation of E2 by bovine granulosa cells.

TL;DR: In this article , the authors used Prostaglandin F2α (PGF2α) and its analogues to induce foaling in prepartum mares.

TL;DR: In this article, the authors used Prostaglandin F2α (PGF2α) and its analogues to induce foaling in prepartum mares.

TL;DR: For instance, this article showed that mammary development in prepubertal gilts was accelerated by injecting exogenous recombinant porcine prolactin during the last third of gestation.

TL;DR: In this paper , the authors highlight the importance of IFNT in corpus luteum (CL) maintenance, acting directly and in a cell-specific manner, in a transcriptomic study revealed a distinct molecular profile of pregnant bovine CL, compared to the non-pregnant gland.
