چکیده

Pro-inflammatory cytokines may contribute to physiological, e.g., tissue reconstruction and vascularization, or pathological, e.g., inflammation or some metabolic disturbances, processes during pregnancy establishment. the current study aimed to investigate il-6 plasma levels at 30 and 45 days post-insemination (dpi) in pregnant and non-pregnant dairy cows. the cows were examined for pregnancy diagnosis at 30 and 45 dpi. cows (n=71) were assigned into four groups: non-pregnant at 30 dpi (n=16), pregnant at 30 dpi (n=36), non-pregnant at 45 dpi (n=11), and pregnant at 45 dpi (n=8). blood samples were collected at 30 and 45 dpi for il-6 assay. results showed high levels of plasma il-6 at 30 dpi either cow-conceived or not. cows with healthy embryos at 45 dpi had lower concentrations of il-6 than cows with late embryonic death. the plasma il-6 concentrations showed different patterns of changes in dairy cows during the first two months of pregnancy.

Abstract
|
pro-inflammatory cytokines may contribute to physiological, e.g., tissue reconstruction and vascularization, or pathological, e.g., inflammation or some metabolic disturbances, processes during pregnancy establishment. the current study aimed to investigate il-6 plasma levels at 30 and 45 days post-insemination (dpi) in pregnant and non-pregnant dairy cows. the cows were examined for pregnancy diagnosis at 30 and 45 dpi. cows (n=71) were assigned into four groups: non-pregnant at 30 dpi (n=16), pregnant at 30 dpi (n=36), non-pregnant at 45 dpi (n=11), and pregnant at 45 dpi (n=8). blood samples were collected at 30 and 45 dpi for il-6 assay. results showed high levels of plasma il-6 at 30 dpi either cow-conceived or not. cows with healthy embryos at 45 dpi had lower concentrations of il-6 than cows with late embryonic death. the plasma il-6 concentrations showed different patterns of changes in dairy cows during the first two months of pregnancy.
