摘要

The aim of this study was to compare ovarian response and embryo yield of Day 0 protocol in Angora goats (AG) and indigenous Kilis goats (KG) in the non-breeding season. A total of 16 Angora goats (AG group) and 11 Kilis goats (KG group) were used in this study. In the synchronization process, after controlled internal drug release withdrawal, when estrus signs were observed, natural mating was performed. Ovarian response was determined by synchronized laparotomy 6 days after natural mating, and number of corpora lutea (CL) was recorded. Embryos were collected and morphologically evaluated by stereomicroscope. Synchronization rates did not differ between AG (88%, 14/16) and KG group (91%, 10/11). In AG and KG groups, the proportion of CL on the right (44% and 53%, respectively) and left (56% and 47%, respectively) ovaries were similar. The CL number per animal did not differ significantly between the two breeds and was determined as 4.4 +/- 0.90 in AG group and 6.4 +/- 1.44 in KG group. Transferable embryo yields were significantly higher in AG group (31/42, 74%) compared to KG group (16/46, 35%) in the non-breeding season (P < 0.01). In conclusion, it is suggested that the day 0 protocol can be used for goat superovulation in the non-breeding season; however, transferable embryo yields are affected by the breed.
