Abstract

The case of 37 multiparous Brahman (34) and F1 Brahman x Simmental (3) cows, which were submitted to an IATF program in the municipality of Maní, department of Casanare, is reported. These are calving cows whose calves at day 0 of the beginning of the IATF protocol were between 45 and 90 days old. The IATF protocol that was used is described as follows: day 0, the insertion of an intravaginal device of controlled release of progesterone (containing 1g of progesterone) and the application of estradiol benzoate (2ml i.m.). On day 8 the device is removed, prostaglandin F2 alpha (2ml i.m.), estradiol cypionate (1ml i.m.), equine chorionic gonadotropin eCG (2ml i.m.) are applied. Finally, on day 10, artificial insemination is performed. Transrectal palpation is performed with the help of ultrasound equipment to check the reproductive status of the female at day 45 post artificial insemination, thus confirming her pregnancy or if she is empty. The entire protocol, methodology, results and discussion of the case are described.
