In this study, it was aimed to determine the effect of oestru synchronization on the fertility of hair goats during the breeding season. Animal material of this experiment consisted of 200 heads of hair goats between 3 and 5 years of age. The animals were divided into two groups, (Control group, KG, n = 100; Oestrus synchronization group, KS, n = 100). The animals in the KS group received intravaginal sponges containing 30 mg flugestone acetate which removed after 12 days and 500 IU of PMSG/per animal administered IM. The animals in both groups were mated using bucks for 4 days. The single birth rate was 72% in the KG and 35% in the KS group. Fecundity and litter size were 1.20 and 1.59 in the control group and 1.25 and 1.64 in the KS group, respectively. As a result, the application of oestrus synchronization in hair goats during the breeding season improved the fertility.
