animals with lower BCS (Group 1 = BCS 1.5 to 2.0; n = 139) had a CR of 47.4%. The animals with BCS from 2.5 to 2.75 (Group 2; n = 741) and BCS from 3.0 to 3.25 (Group 3; n = 463) had a CR of 47.6% and 51.2%, respectively. The animals with higher BCS (Group 4 = BCS 3.5 to 4.0; n = 231) had a CR of 45.3% (P > 0.05). It was concluded that conception rates were similar between the animals presenting different BCS in the herd, likely because the eCG minimized the effects of low LH pulsatility in
