Figure 1

Cumulative percentage of pregnancy in prepubertal Bos indicus heifers throughout a 45 d AI breeding season. Heifers were assigned to receive, between d-12 and 0, no treatment (CIDR0), a new intravaginal insert (CIDR1), or a similar intravaginal insert that had previously been used three times (CIDR4). Heifers were artificially inseminated 10 to 14 h after detection of estrus; those that returned in estrus after the first service were re-inseminated. Adapted from Claro Júnior et al. [15].
