Cold exposure affects glucose metabolism, lipid droplet deposition and mitophagy in skeletal muscle of newborn goats Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2024-03-08 Duo Su, Yulong Song, Die Li, Shizhong Yang, Siyuan Zhan, Tao Zhong, Jiazhong Guo, Jiaxue Cao, Li Li, Hongping Zhang, Linjie Wang
Cold exposure is a common stressor for newborn goats. Skeletal muscle plays an important role in maintaining whole-body homeostasis of glucose and lipid metabolism. However, the molecular mechanisms underlying regulation of skeletal muscle of newborn goats by cold exposure remains unclear. In this study, we found a significant increase ( < 0.01) in serum glucagon levels after 24 h of cold exposure

Estradiol-17β (E2) increases kallikrein in rodent and human reproductive tissues. Kallikrein specific activity is increased in the porcine uterus when conceptus E2 is secreted at maternal recognition of pregnancy. When kallikrein acts on kininogen to liberate bradykinin, angiogenic and vasoactive factors are released. The uterus of ovariectomized ewes administered E2 undergoes rapid vascular changes

Sexually active male goats stimulate the endocrine and sexual activities of other males in seasonal sexual rest through the “buck-to-buck effect” Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2022-06-02 J.A. Delgadillo, L.A. Espinoza-Flores, J.A. Abecia, H. Hernández, M. Keller, P. Chemineau
Male goats rendered sexually active by exposure to a photoperiodic treatment are more efficient than untreated goats in stimulating LH secretion and ovulation in seasonally anestrous goats. This phenomenon is called the "male effect." Here, we determined whether sexually active bucks are able to stimulate the endocrine and sexual activities of other bucks in seasonal sexual rest through the phenomenon

Quantifying heat stress; the roles on metabolic status and intestinal integrity in poultry, a review Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2022-05-18 A. Hosseindoust, H.K. Kang, J.S. Kim
Heat stress adversely affects intestinal barrier integrity ranging from minor enterocyte injury to fatal inflammatory heat shocks. The current review discusses the physiological mechanisms of the adaptive response of poultry and the nutritional interventions to improve intestinal integrity during heat stress. There are several possible metabolic mechanisms of protection including stress adaptation

The effect of capromorelin on glycemic control in healthy dogs Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2022-05-08 K.M. Pascutti, A.L. O'Kell, R.C. Hill, R.A. Castro, M.E. Salute, C. Gilor
Capromorelin is a ghrelin-receptor agonist widely used as an appetite stimulant in dogs. Capromorelin disrupts glucose homeostasis in cats but information regarding its effects on canine glucose homeostasis is lacking. The study objective was to evaluate the effect of capromorelin on glucose homeostatic mechanisms in healthy dogs. Eight clinically healthy client-owned adult dogs were enrolled in this

Early pregnancy regulates the expression of prolactin and its receptor in the thymus, the liver, the spleen and lymph nodes in sheep Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2022-05-05 Pengfei Feng, Jiaxuan Wu, Ying Ren, Leying Zhang, Jianhua Cao, Ling Yang
As a pituitary hormone, prolactin (PRL) is also synthesized by immune system cells, and exerts its effects on the immune system by binding to its receptor (PRLR) via endocrine and paracrine/autocrine pathways. The immune organs adapt to the presence of fetal alloantigens during pregnancy, and the immune system is composed of primary organs and secondary organs. The objective of this study is to analyze

Effects of methionine, leucine, and insulin on circulating concentrations and mammary extraction of energy substrates and amino acids in lactating dairy cows Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2022-04-14 Virginia L. Pszczolkowski, Haowen Hu, Jun Zhang, Meghan K. Connelly, Amelia S. Munsterman, Sebastian I. Arriola Apelo
The aim of this experiment was to test whether insulin potentiates the effects of two abomasally infused amino acids (AA), leucine and methionine (LM), on mammary extraction efficiency of energetic and nitrogenous nutrients. Six lactating Holstein cows (155 ± 9 DIM) were ruminally-cannulated and had the right carotid artery subcutaneously transposed. Cows were fed a 20% metabolizable protein-restricted

Predictors of the ovarian superstimulatory response and oocyte collection in prepubertal heifers Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2022-03-29 A.R.T. Krause, F.C.F. Dias, S.L. Caunce, G.P. Adams, R.J. Mapletoft, J. Singh
The objectives were to investigate the relationships between antral follicle counts and plasma AMH and FSH at the time of follicular wave emergence in prepubertal calves, and to determine the effects of age and duration of gonadotropin treatment on the ovarian superstimulatory response in pre- and post-pubertal heifers. Hereford crossbred prepubertal (Replicate 1 and 2, n = 20) and post-pubertal heifers

Altrenogest treatment reduces the stress response of three-year-old warmblood mares during their initial equestrian training Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2022-03-20 M. Kaps, Anne Lutzer, C. Gautier, C. Nagel, J. Aurich, C. Aurich
Horse mares are frequently treated with the progestin altrenogest with the aim to suppress estrous behavior and its negative impact on equestrian performance. Progestogens, however, also have sedative effects in males, and females of different species. The aim of our study was therefore to investigate altrenogest-induced changes in the stress response of female horses during initial equestrian training

Inverse relationship between eosinophil profiles and serum glucose concentration in dogs with naturally occurring hypercortisolism Domest. Anim. Endocrinol. (IF 2.1) Pub Date : 2022-03-17 Jimin Oh, Dohee Lee, Taesik Yun, Yoonhoi Koo, Yeon Chae, Mhan-Pyo Yang, Byeong-Teck Kang, Hakhyun Kim
Hyperglycemia and eosinopenia are well-known characteristics of hypercortisolism (HC) in humans, however, their association in dogs with HC has rarely been reported. This study aimed to evaluate the association between eosinophils and serum fasting glucose concentration in dogs with HC. Forty-seven dogs with HC and 43 dogs with non-adrenal illness were included. In this retrospective cohort study,
