Influence Of Tigernut (cyperus Esculentus L.) On The Semen Characteristics And Testicular Parameters Of Rabbits

摘要

Twelve sexually mature Dutch rabbits were used to evaluate the influence of tigernut (Cyperus esculentus) on the reproductive characteristics of rabbits. The treatment group (T_2) was compared to an untreated group (T_1). Results showed that semen volume of T_1 (0.30±0.03ml) was significantly higher (P<0.05) than the T_2 (0.21+0.1 ml). The sperm concentration of T_2 (345.28±46.60 × 106 /ml) was significantly higher (P<0.05) than T_1 (153.33±27.78 × 106 /ml). There were no significant differences (P>0.05) in sperm motility, live/dead and reaction time between the two groups. The testicular parameters revealed no significant differences (P>0.05) in the testes weight, vas deferens, testis length, right testis circumference, epididymal length, paired testis weights and weight of reproductive tract between the groups. However, significant differences (P<0.05) existed between the groups in the left testis circumference (LTC) and weight of left epididymis (LEW) between groups. Although semen volume of the T_2 was depressed its spermatozoa concentration was higher than that of T_1. This is indicative of higher chances of fertility of T_2 group and could be processed for further usage in artificial insemination (Al) programs.
