Ovarian follicular cysts are an important cause of infertility in goats, yet limited information is available regarding their clinico-endocrine characteristics and therapeutic management. Fourteen goats with follicular cysts were evaluated using ultrasound and were treated with two protocols: Ovsynch (Group I, n=6) and intravaginal progesterone sponge (Group II, n=8). Affected goats had a mean age of 2.4 ± 0.27 years and body condition score of 2.5–3.5. Follicular cysts were either solitary with mean size of 11.0 ± 0.9 mm or multiple having a mean size of 9.50 ± 0.27 mm. The mean wall thickness of cyst was 1.10 ± 0.023 mm and the uterus was uniformly hypoechoic with occasional luminal contents. Serum oestradiol concentration was 41.78 ± 4.26 pg/dL and 36.74 ± 3.11 pg/dL in group I and group II, respectively, in affected goats and following treatment the mean values were 42.38 ± 6.67 pg/dL in Group I and 40.51 ± 3.64 pg/dL in Group II at induced oestrus. Mean progesterone level was 0.62 ± 0.28 ng/mL on the day of presentation and remained <1 ng/mL at induced oestrus in both the groups. Post-treatment fate of cyst revealed regression (16.7% Group I; 12.5% Group II), luteinisation (50% both groups) and persistence (33.3–37.5%). Dominant follicles were detected in 50 percent of goats in both the groups following therapy with non-significant difference in the mean size (7.35 ± 0.51 mm in Group I; 6.90 ± 0.54 mm in Group II). Conception rates at induced oestrus were 16.67 and 50 per cent, respectively, indicating better outcomes with the intravaginal progesterone sponge protocol.
