  "abstract": "<p>The present study was performed to determine the effect of PGF2&alpha; and GnRH injections in different time intervals on<br>fertility in Hair goats during breeding season. Totally, 80 primiparous Hair goats were divided into four groups (n=20 in<br>each) according to the body condition scores of the animals. The animals in groups were treated as follows; first group<br>(Ovsynch), GnRH on day 0, PGF2&alpha; on day 7 and GnRH on day 9; second group (2PG-G), PGF2&alpha; on day 0, PGF2&alpha; on day<br>7 and GnRH on day 9; third group (PG-G), PGF2&alpha; on day 7 and GnRH on day 9; fourth group (G), GnRH on day 9.<br>Bucks were included into the groups on day 10-14 and insemination was performed during standing heat. Blood samples<br>were collected to determine possible embryonic losses on day 21 for further analysis of serum progesterone<br>concentrations. Transabdominal ultrasonography was performed to detect pregnancy on day 40-45. It was determined<br>that in Ovsynch, 2PG-G, PG-G and G groups, estrous rate was 100%, 95%, 95% and 85%; pregnancy rate was 85%,<br>95%, 95% and 85%; kidding rate was 100%, 78.9%, 94.7% and 88.2%; twinning rate was 41.2%, 40%, 22.2%, 20%;<br>litter size was 1.41, 1.40, 1.22, 1.20, respectively. However, these parameters did not show any significant difference<br>between groups (P&gt; 0.05). In conclusion, it is suggested that all treatment procedures may be used for estrous<br>synchronization in Hair goats during breeding season due to the satisfactory results</p>",
