Abstract

Efficacy of oestrous synchronization and post-treatment fertility was studied in a herd of 149 dairy goats (Swiss breed no. = 104, indigenous Greek breed no. = 45) kept under an extensive farming system. All does were synchronized during the transitional period (during July prior to the breeding season) using fluorogestone acetate (FGA) impregnated intra-vaginal sponges, equine chorionic gonadotropin (eCG) and different prostaglandin F2a (PGF2α) analogues. Four doses of prostaglandin F2a (group 1: 4·5 mg luprostiol; group 2: 2·25 mg luprostiol; group 3: 0·2 mg cloprostenol; group 4: 0·1 mg cloprostenol) were administered i. m. 48 h prior to the end of progestagen treatment and 400 IU eCG was administered at sponge removal. All does were inseminated with fresh semen (300 ✕ 106 spermatozoa per insemination) 42 to 44 h after sponge removal. There were no significant differences (P > 0·05) in the number of goats showing ovarian activity (blood progesterone concentration ³ 1 ng/ml) prior to oestrous synchronization between PGF2α treatment groups. No significant differences (P > 0·05) were observed for the kidding rates between the treatment groups. Our results indicate that goats with ovarian activity prior to sponge application who received high doses of PGF2α showed lower conception rates than those detected in anoestrus (P 0·05). No differences (P 0·05) were observed in conception rates between groups that received lower doses of PGF2α. July is considered to be a transitional period suitable for oestrous synchronization for both Swiss and indigenous dairy goats. Natural mating during the two subsequent cycles after artificial insemination improved kidding rate, but without any significant difference either between treated groups or between Swiss and indigenous breeds.
