Abstract: Objetivou-se avaliar o efeito do número de utilizações (até três) do CIDRÒ, manifestação de estro e ordem de parição sobre a taxa de prenhez em vacas Bos indicus. Utilizou-se 1176 vacas pluríparas e primíparas, lactantes, 30 a 60 dias pós-parto. Os grupos receberam CIDRÒ de primeiro, segundo ou terceiro usos, mais 2,0 mg de benzoato de estradiol no dia de introdução (D0) e, 500 μg de dinoprost trometamina, 300 UI de eCG e 0,6 mg de cipionato de estradiol na retirada dos dispositivos (D8), com a IATF 48 horas a… Show more

“…In the present study, we found similar P/AI in the two groups (56.2% for GRN and 57.0% for GRU; p > 0.05), because both groups were subjected to the same hormonal protocol (Table ). While working with Bos taurus indicus cows, Medalha et al () obtained significantly lower P/AI values (44.8%) using new intravaginal devices with P4. Therefore, significant variations in the P/AI of cows subjected to the TAI protocol were found in several studies, and these variations have persisted over time, with few exceptions.…”
