الملخص الإنجليزي

Nine male Meriz bucks, aged 3-4 years, were randomly distributed equally into three groups to study the effect of injection (1ml) normal saline (control group), (10i.u.) oxytocin and (75 g) prostaglandin (P) F2α on semen characteristics and libido traits.Semen samples were collected at weekly intervals by Electro-ejaculator and evaluated for semen traits.

Libido traits were measured at biweekly intervals for 20 minutes.

Result revealed that injection of oxytocin significantly (p<0.05) improved semen volume (0.77 ± 0.07 vs.

0.62 ± 0.04), color (3.40 ± 0.23 vs.

2.79 ± 0.16), individual motility (69.88 ± 4.09 vs.

53.33 ± 4.14), sperms' concentration/ml *107 (94.11 ± 11.76 vs.

64.11 ± 9.72) and live sperms' percent (64.96 ± 4.53 vs.

47.31 ± 4.09) compared to control bucks.Injection of PGF2α did not have a significant effect on semen characteristics.

However, it improves mass and individual motility and decreases sperm abnormalities at a long term effect.

Month of semen collection had a high significant effect (P≤0.01) on most of the semen characteristics, the maximum was recorded in September, while the minimum was recorded in June and July.Oxytocin had no significant effect on all examined traits of libido.Injection of PGF2α had a significant effect (p<0.05) in reducing reaction time to 1st mount (21.20 ± 3.15 vs.

114.70 ± 28 sec.) and in an increasing the number of successful ejaculate (2.70 ± 0.37 vs.

1.58 ± 0.19) compared to control bucks.

Month had a significant effect (P≤0.05) on the most libido traits, the minimum reaction time to 1st mount (47.55 ± 12.53 sec.), reaction time to 1st ejaculate (1.61 ± 0.48min.) and the maximum number of successful ejaculate (3.22 ± 0.41) was recoded in September and July, while the maximum reaction time to 1st mount (170.55 ± 84.98 sec.), reaction time to 1st ejaculate (6.80 ± 1.45 min.) and minimum number of successful ejaculates (0.77± 0.22) was recorded in June.
