EFFECT OF DIETARY SUPPLEMENTATION WITH SEAWEED AND POLYPHENOLS MIXTURE ON ANTIOXIDANT STATUS, CONCENTRATION AND MOTILITY OF RABBIT SPERMATOZOA
Keywords:antioxidant, motility, polyphenols, rabbit, spermatozoa concentration, seaweed
In recent years, many studies have been focused on natural substances that could have effect on health of animals. We investigated effect of extract consisting mainly of polyphenols, brown algae and plant polysaccharides on the reproduction potential of male rabbits (New Zealand white breed) during 60 days long dietary experiment. The rabbits were divided into three groups. Control was fed a basal diet, whereas the second and third group were supplemented with seaweed and polyphenols mixture: T1 = 0.3% and T2 = 0.6% respectively. We observed that sperm concentration in both experimental groups increased in comparison to the control group. Results of the CASA analysis showed enhanced motility (C = 85.09Â±7.53%, T1 = 87.21Â±8.25%, T2 = 89.38Â±8.02%) and progressive motility (C = 74.28Â±12.6%, T1 = 79.07Â±13.89%, T2 = 81.28Â±11.37%) in experimental groups supplemented with combination of algae and polyphenols in comparison with the control group. While monitoring ferric reducing ability of plasma (FRAP), we found the highest value in T1 group, changes were insignificat. An increase in GPx activity was measured in experimental groups in comparison with the control group with major difference in T1 group. In experimental groups, we determined an increase in activity of superoxide dismutase (SOD) in comparison with control group, the difference was significant in T2 group (C = 0.26Â±0.11 U/mg TP; T2 = 0.31Â±0.09 U/mg TP). In conclusion, our studies suggest that dietary supplementation with brown seaweed and plant polyphenols mixture may be potentially useful for enhancement of sperm motility and protection against oxidative stress.
