Evaluating the Impact of Clinical Mastitis on Ovarian Morphometry and the Effectiveness of the Synchronisation Protocol in Dairy Cows

Animals
Inflammatory processes within the body have been hypothesised to be causative agents of various health complications, including reproductive issues. This study investigates the effects of mastitis on ovarian morphometry and fertility outcomes while also ...

Comparison of blood metabolites and GSH-Px, SOD, MDA levels as a predictor of pregnancy in primiparous cows after the Presynch-Ovsynch protocol

, 2022
The reactive oxygen species level and antioxidants have determinative roles in gamete development, steroid synthesis and fertilization. The objective of the current study was to compare some metabolic and antioxidant parameters in primiparous cows with and without pregnancy after the presynch-ovsynch protocol in the postpartum period.

Benefits of using Double-Ovsynch versus presynch-ovsynch are affected by environmental heat in primiparous holstein lactating cows

Animal Reproduction Science, 2023
Optimized reproduction management enhances fertility of dairy cows, and thus improves their milk production efficiency. Comparing different synchronization protocols under variable ambient conditions would be conducive to protocol selection and production efficiency improvement.
