The objective was to compare the reproductive performances of Brown Swiss cows and heifers synchronized for estrus and ovulation using prostaglandin F 2 alpha (PGF_{2\alpha}) alone or with gonadotropin-releasing hormone (GnRH). Primiparous and multiparous cows (45 to 75 days postpartum; n = 26) and nulliparous heifers (16 to 20 months; n = 26) were randomly assigned to 2 treatment programs. GnRH injection was followed in 7 days by PGF_{2\alpha} injection and then by another GnRH injection 9 days later. Artificial insemination (AI) was performed 16 h after the second GnRH injection. Injections of PGF_{2\alpha} were given 11 days apart AI …
