Topic:Equid Semen
Equid semen refers to the reproductive fluid produced by male horses, which contains sperm cells necessary for fertilization. The quality and viability of equid semen are important for successful breeding programs and can be influenced by various factors, including genetics, age, diet, and environmental conditions. Key parameters used to assess semen quality include volume, concentration, motility, and morphology of sperm cells. Techniques for collecting, evaluating, and preserving equid semen, such as cryopreservation, are critical for artificial insemination practices. This page compiles peer-reviewed research studies and scholarly articles that explore the physiology, assessment, and management of equid semen in the context of equine reproduction.
L-carnitine added to post-thawed semen acts as an antioxidant and a stimulator of equine sperm metabolism. The objective of this study was to enhance the in vitro sperm quality and in vivo fertility of frozen-thawed equine semen by the addition of l-carnitine (LC) to post-thawed semen. Different concentrations of LC were added to thawed samples to obtain four treatments control and 0.5, 1 and 2 mM LC. In the in vitro experiments, sperm motility and kinematics, membrane integrity and intracellular calcium ion concentration ([Ca ] ) were investigated, and the antioxidant bioactivity of LC was assessed by measuring hydrogen peroxide and nitrite concentrations (NO ). The fertility rate was assessed v...
