Resumo

This study aimed to evaluate the pregnancy rate in cyclic lactating dairy cows inseminated at fixed timeusing eCG in the withdrawal of progesterone implant. The experimental design was a randomized blocks, twotreatments with 32 repetitions for G1 and 31 repetitions for G2. The G1 control group: cows with hormonalprotocol with the use of eCG; G2: cows with hormonal protocol without using eCG. The study presented to theGroup eCG with pregnancy rate of 28.13%, while no eCG group had a 16.13% pregnancy rate. The statisticaldifference between the groups was not significant (p = 0.2522). In conclusion, the use of eCG had no influenceon the pregnancy rate.(AU)
