ABSTRACT The objective of this study was to compare reproductive performance and progesterone (P4) concentration in serum of synchronized ewes with new and reused (up to five times) CIDR in five-day protocols. Two experiments were conducted in the reproductive season, in two consecutive years. In experiment 1: 125 µg of PGF2α and 200 IU of eCG were applied at removal of the CIDR: CIDR1-200 (new intravaginal devices, control), CIDR2-200, CIDR3-200, CIDR4-200, and CIDR5-200 (groups with CIDR from second to fifth […]
