Título em português: Uso de insulina para aumento da fertilidade de vacas de corte pós?parto lactantes inseminadas.  aThe objective of this work was to evaluate the effect of insulin alone or in association with equine chorionic gonadotropin (eCG) on the fertility of postpartum beef cows subjected to synchronization. A total of 340 cows was subjected to fixed time artificial insemination. In the trial 1, the cows were subjected to temporary weaning (TW), while in the trial 2 the same protocol was tested without TW. The addition of an insulin injection to a progesterone/eCG-based protocol without TW increased the pregnancy rate of beef cows with body condition score (BCS) equal to or lower than 2.5. Insulin had no effect on cows submitted to TW or with BCS equal to or higher than 3.0.  aCattle  aEquine chorionic gonadotropin  aInsulin  aWeaning  aBos Taurus  aDesmama  aInsulina  aECG  aFTAI1 aPFEIFER, L.
