| The aim of this study was to determine the effects of giving minsed Nigella Sativa per mouth on semen characteristics (volume, concentration, mass motility, individual motility, live dead sperms, abnormal sperms, osmotic pressure). In this study 9 health Awassi rams, at age 3- 5 years and weighing 50- 60 kg, were used. Rams were divided randomly into 2 groups (4 in control group and 5 in treatment group). Minsed black seed was administered orally as a bolus at a dose 0.1 kg B.W daily for 60 days, semen samples were collected from the rams by artificial vagina after 30, 45, 60, 75 days for examination of semen characteristics. Results of the present study showed that using minsed Nigella Sativa gave a significant (P<0.05) increase in semen characteristics (volume, concentration, mass motility, Individual motility, live dead sperms) compared with the control group at 60 days. There was a significant decrease (P<0.05) in the number of the abnormal sperms in treated group compared with control group. There was no significant differences in semen osmotic pressure between the two groups. It was concluded from this study that minsed Nigella Sativa gave a positive effect on ram semen characteristics when its given for 60 days. |
