Persistently high concentrations of β-hydroxybutyrate affect hepatic SOD2 expression and blood SOD activity in high-yielding dairy cows.

Background: Elevated BHB levels are hypothesized to influence hepatic antioxidant enzyme expression and activity, contributing to oxidative response. However, the impact of BHB between 0.8 and 1.

Connections between Endometrial Health Status, Fatty Liver and Expression of Endocannabinoid System Genes in Endometrium of Postpartum Dairy Cows.

The endocannabinoid system (ECS) plays a crucial role in reproductive health, but its function in postpartum dairy cows remains poorly understood. This study investigated the expression patterns of ECS-related genes in the endometrium of postpartum dairy cows and their associations with endometrial health and the presence of fatty liver. Endometrial biopsies were collected from 22 Holstein Friesian cows at 4 and 7 weeks postpartum.

Acrylamide-induced Changes of Granulopoiesis in Porcine Bone Marrow.

Introduction: Due to the widely documented and diverse toxic effects of acrylamide, the authors decided to evaluate the impact of high and low doses of this compound on the process of granulopoiesis in porcine bone marrow.

Material And Methods: The experiment was conducted on 15 Danish Landrace pigs at the age of 8 weeks. The animals were randomly assigned into three equal groups (n = 5).
