O objetivo do trabalho foi avaliar a influência diâmetro folicular no momento da inseminação artificial em tempo fixo sobre taxa de prenhez vacas Nelore. Foram sincronizadas 225 fêmeas D0 com dispositivo intravaginal, contendo 1g progesterona e aplicação 2,0 mg via intramuscular benzoato estradiol. No D7 foram aplicadas 300 UI gonadotrofina coriônica equina 500 µg cloprostenol sódico. D8, retir...

The objective of the study was to compare pregnancy rates after short-term and long-term synchroniza-tion protocol in Kivircik ewes. Ewes (n=54) were randomly divided into two synchronization groups as ST (short-term; n=27) or LT (long-term, n=27). Intravaginal sponge inserted on same day (D0) both groups. It removed at 7 days (D7) group 13 (D13) group. All ewes received 450 IU eCG 75 μg d-clop...
