Piglet losses in pig farming remain a concern and need to be addressed through the implementation of new sustainable breeding and management strategies. Indeed, piglets are particularly vulnerable in the first days of life. This review provides an overview of the current knowledge on piglet responses during adaptation to life outside the uterus, which is particularly important for improving the vitality of newborn piglets and animal welfare in pig production in various farming systems.

Three-way crossbreeding was performed with Australian White, Dorper, and Charollais as terminal male parents and elite F1 hybrids of Australian × Han, Dorper × Han, and Charollais × Han as female parents. Based on the growth of three-way crossbred and Small-tailed Han lambs as well as the effects of CLPG, the offspring of male Australian White and female Charollais × Han showed apparent heterosis, and the individuals with the T allele had improved body weight and body size.

This study aimed to evaluate the effect of concentrate-based feeding (CF) and artificial pasture-based grazing (APG) management systems on milk yield, fatty acid, nutritional indices, and milk physicochemical characteristics of Awassi ewes.

The effect of STEAP4 (six-transmembrane epithelial antigen of the prostate 4) on goat adipocyte differentiation is unclear. We cloned the goat STEAP4 gene based on the Jianzhou Da’er goat and analyzed its properties and its expression in tissues and adipocytes; further, the positive effect on the expression of subcutaneous adipocytes was obvious. This study will provide a basis for elucidating the biological function of the STEAP4 gene in goat and provide a reference for goat molecular breeding.

This study aimed to determine the effect of fenugreek seed supplementation on milk yield and milk quality characteristics in dairy goats. The goats' milk yield was not affected by fenugreek seed supplementation, whereas an increased milk fat content and decreased serum cholesterol and triglyceride level were observed. Fenugreek seed supplementation increased the oleic acid, elaidic acid, and arachidonic acid concentrations and changed the volatile compounds found in milk.

This publication aims to describe the physiology of the mammary gland and its immune mechanisms and to approximate their connection with potential mastitis resistance genes. It describes various options for mastitis elimination and focuses on genetic selection and a closer specification of resistance genes to mastitis.

We present a novel study of the effect of bta-miR-33a on lipid metabolism in bovine mammary epithelial cells (BMECs). The correlation between bta-miR-33a and target gene ELOVL6 is also verified by a luciferase reporter assay. We show that bta-miR-33a directly inhibits the expression of ELOVL6 in BMECs, altering the mRNA expression of relative genes. This suggest that bta-miR-33a regulates lipid metabolism by targeting ELOVL6, which might be a potential molecular marker of milk fat composition.

This study aimed to investigate the relationship between increases in luteinizing hormone (LH) profiles induced by gonadotropin-releasing hormone (GnRH) in the serum and vaginal mucus of Japanese Black beef cows. A peak serum LH concentration was identified at 2.5 h post-GnRH administration, with serum concentrations returning to near-pre-GnRH-administration values after 6.5 h, whereas the peak LH concentration of vaginal mucus was identified 4.5 h after GnRH administration.
