Effects of the Progesterone-Based Estrus Synchronization on Some Reproductive Parameters in Abaza Goats

18393

This study was undertaken to investigate the effects of progesterone-based synchronization on reproductive characteristics and fertility outcomes for the first time in native Abaza goat breed. A total of 40 Abaza goats, weighing 40-50 kg, aged 2-5 years, were used in the trial. The study was conducted during the mating season. Group 1 (n=15) received hormone administration with progesterone and estrus synchronization. Group 2 (n=25) did not receive hormone administration (control group). The length of estrus was 25.1±2.11 and 25.4±3.69 hours in Groups 1 and 2, respectively. The rate of pregnancy in the first estrus was 73.33% and 88% respectively in Group 1 and 2, respectively. Moreover, the duration of pregnancy was 153.50±3.21 and 151.26±3.89 Group 1 and 2 respectively. There was no statistically significant difference between the groups in terms of estrus duration, first estrous pregnancy rate, duration of pregnancy, and time of birth. It was especially found that the births were daytime and 72.98% between 06.00 and 12.00 hours (P 0.001). During the study, only 1 follicular cyst, 1 premature birth and 1 dystocia were encountered. Group 1 twin ratio (53.34%) was statistically significantly higher than Group 2 (12%) (P=0.005). The goats had 27 single (14 male - 13 female) and 10 twin (10 male - 10 female) births. As a result, it was determined that the Abaza goats did not have many reproductive problems, their births were daytime, the twin births were low and synchronization application has no negative effect on the production.
