Efficacy of Short-Term Timed Artificial Insemination Protocols With Estradiol Esters and PGF2α in Girolando Cows. [PDF]

Reprod Domest Anim
ABSTRACT Using a synchronisation protocol based on estradiol esters and prostaglandin, established in cattle since the 1970s, we implemented 24 or 48‐h intervals between hormone administration and timed artificial insemination (TAI). This study compared two short‐duration TAI protocols using estradiol benzoate (EB) and cypionate (EC) as ovulation ...
