dc.description.abstractThe aim of this study was to investigate the relationship between different estrus synchronization protocols, some fertility parameters and serum biochemical parameters including total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), thyroid stimulating hormone (TSH), estradiol (E2) and progesterone (P4) in Hair goats. The study was carried out on 150 female Hair goats during the breeding season. Goats were divided into three groups as control (n = 50), short-term (n = 50) and long-term (n = 50) groups. Control group did not receive any treatment, short-term group received intravaginal P4 (7 d) combined with GnRH (on days 0 and 9) and PGF2? (on day 7), and long-term group received intravaginal P4 (12 d) combined with pregnant mare?s serum gonadotropin (on day 12) and GnRH (on day 13). In control group, blood samples were collected at the beginning (first measurement) and 7th day (second measurement) of the study. In short-term and long-term groups, blood samples were collected at the time of sponge insertion (first measurement) and withdrawal (second measurement). Serum TAS, TOS, P4, E2, TSH levels were measured on all sampling days, and OSI was calculated. All the groups were observed for estrus behavior and those showing the signs of estrus were allowed for mating. Transrectal ultrasound examination was performed to diagnose pregnancy approximately 40 days after mating. The onset of estrus was earlier in short-term group compared to long-term group (P < 0.001). The estrus and pregnancy rates were significantly higher in short-term group compared to other groups (P < 0.05). At the time of first measurement, E2 level in short-term group and P4 level in long-term group were higher and lower than the other groups, respectively (P < 0.05). At the time of second measurement, TAS, TOS, OSI and E2 levels were significantly different in short-term group compared to control and long-term groups (P < 0.01). Additionally, P4 level in control group and TSH level in long-term group increased (P < 0.01). While TAS level in short-term group and E2 level in all groups increased from the first measurement to the second measurement, the TOS and OSI values decreased (P < 0.01). TSH level in short-term group decreased from the first measurement to the second measurement (P < 0.01), while it increased in long-term and control groups (P < 0.05). In conclusion, it was obtained that synchronization protocols can affect serum TAS, TOS, E2, P4, TSH and OSI levels; and shortterm intravaginal P4 treatment combined with GnRH and PGF2? clearly improved the antioxidant defense system and increased fertility parameters in Hair goats.en_US
