“…Kinematic parameters reflect the ability of sperm to migrate through the mare's reproductive system for fertilization (Alvarenga et al., 2016). In this study, an increase ( p < 0.05) was observed after supplementation with nutraceutical, which agrees with what was reported in Colombian stallions (Usuga et al., 2017), Quarter Horses (Nery et al., 2020), Dare‐Shuri (Bahrami et al., 2020) and Arabs (El Sisy et al., 2016), this can be attributed to the fact that antioxidants such as l ‐carnitine provide energy to sperm by increasing the transport of fatty acids to the mitochondrial matrix (Mongioi et al., 2016). However, in other studies, the kinematic parameters did not increase after nutraceutical supplementation (Alamaary et al., 2019; Brinsko et al., 2005; Ravi et al., 2016).…”

BackgroundThe use of reproductive biotechnologies in equine practice has shown that some stallions are subfertile, so ways to improve fertility have been sought.ObjectiveThis study aimed to evaluate the effect of nutraceutical supplementation on improving semen quality in Quarter Horse stallions.MethodsSemen from six Quarter Horse stallions was assessed for 4 months every 20 days using the computer‐assisted semen analysis system. They were evaluated for 60 days before supplementation; then, the same stallions were re‐evaluated for 60 days with nutraceutical supplementation (30 g/day).ResultsVolume showed no significant difference (p > 0.05) with nutraceuticals. Sperm concentration (10x6) was significantly higher with supplementation (339.4 ± 17.5 sperm/mL) than without supplementation (224.6 ± 19.9). Sperm abnormalities (%) were significantly (p < 0.05) lower with supplementation (14.3 ± 0.6) than without supplementation (19.1 ± 0.4). Sperm kinematic parameters, total motility (TM), progressive motility (PM), rectilinear velocity (VSL), the velocity of the trajectory (VAP) and curvilinear velocity (VCL), were significantly better with supplementation (p < 0.05).ConclusionsBased on the results, it is concluded that nutraceutical supplementation improved semen parameters in Quarter Horse stallions.
