|Description:||The dominant follicle reaches its maximum diameter on the sixth day after ovulation or seven days after the onset of estrus (Castro et al., Theriogenology, 52: 399-411, 1999). This study investigated the effect of hCG administration on the seventh day after the onset of estrus (D7) on pregnancy rate in Toggenburg goats. The study was conducted during December and January in Piau, MG, Brazil (latitude 21°35?S and longitude 43°15?W). For statistical analysis, the chi-square test was used with a significance level of 5%. The pregnancy rate of the animals receiving hCG was superior (P=0.047) than those receiving saline [90.7% (39/43) and 74.4% (32/43)]. We conclude that the use of hCG seven days after hormonally induced-estrus is an efficient strategy to increase the pregnancy rate in dairy goats.|
