Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Veterinary Medicine - Department of Theriogencology Summary: This study was carried out in 4 experiments for studying important points associated with reproductive performance in goats. First experiment aimed to investigate the incidence, timing and factors associated with embryonic / fetal losses (EFL) in 151 goats of different breeds [zaraiebi, Damascus, and cross goats]. All goats were examined by B- mode ultrasonography to monitor EFL during different stages of gestation. Results revealed a high EFL% between D20-23 to D47- 54 (19.61%) compared to the period > D47-54 to birth (11.76 %). A high EFL% was observed in Zaraiebi goats compared to others. The goats that were synchronized by P4 sponge, as well as, artificially inseminated showed a higher EFL % compared to goats with spontaneous estrus, and bred by natural mating, respectively. The 2nd experiment goaled for evaluating testicular blood flow at supratesticular artery (STA) in 8 male Shiba goats by color Doppler ultrasonography after administration of either GnRH or hCG. Results indicated an increase of testicular blood flow in both groups. However, this increase was significantly higher and earlier in hCG group 1 hour than that in GnRH group 2 hours
