This study aimed to establish the best day for such diagnosis in dairy goats. The results showed that subjective luteal vascularization assessment by color Doppler US was a reliable tool for early pregnancy diagnosis in goats and can be efficiently used as early as 21 days post-breeding.openAccessDiagnostico de prenhezCaprinoCabra LeiteiraDairy goatsPregnancy diagnosisUltrasonographyEarly diagnosisBrazilResumo em anais e proceedings
