Effect of estradiol benzoate on Crestar and eCG synchronization for timed insemination in lactating beef cows

Effect of estradiol benzoate on Crestar and eCG synchronization for timed insemination in lactating beef cows

Revista Brasileira de Reproducao Animal 27(3): 432-434

The aim of this study was to verify the efficacy of estradiol benzoate (EB) implantation or 24 h after the removal of norgestomet (NOR) implants for timed artificial insemination (TAI). Treatments were performed in Bos indicus (Nelore) and Bos indicus x Bos taurus (Nelore-Simmental and Nelore-Angus) lactating cows (n=326). On day 0, cows in experiment 1 (group 1, n=82 and group 2, n=75) received a NOR ear implant and estradiol benzoate (EB) plus NOR i.m. administration.
