The efficiency of estrus synchronization and reproductive performance was evaluated in 120 indigenous goats (Capra prisca) in the breeding season. Treatments were fluorogestone acetate (FGA)-impregnated sponges, FGA-impregnated sponges plus intramuscular injection of 400IU pregnant mare serum gonadotrophin (PMSG), Double intramuscular injection of prostaglandin F_2α (PGF_2α), FGA-impregnated sponges plus intramuscular injection of PGF_2α, and FGA-impregnated sponges plus intramuscular injection of PGF_2α and 400IU of PMSG. Estrous response to treatment was ≥95 % in all treatments. Onset of estrus and estrous duration varied significantly among treatments, whereas fertility rate, gestation length, prolificacy and birth type did not differ (P>0.05). The use of FGA-impregnated sponges, and FGA-impregnated sponges plus intramuscular injection of 400IU PMSG was effective in the attainment of early and compact synchronization of estrus in goats.
