Abstract

This project with the “Business Practice” degree work modality was carried out together with the team of the Regional Committee of Livestock Farmers and farms associated with the company. In the period March - July 2024. The objective of this work is to contribute to the productive efficiency of cattle through the Fixed-Time Artificial Insemination (IATF) and Embryo Transfer (ET) programs to guarantee an improvement in a short time. genetics of cattle in the Municipality of Tame Arauca. The study population was made up of 6 lots of bovine females for a total of 243 cows, between 2 to 11 years of age with body condition between 2.5 to 3.0 for lactating females and >3.0 to 3.5 for calving females. The management of the recipients was under similar conditions; they were examined through transrectal ultrasound, guaranteeing the optimal state of the reproductive system. Considering the percentage of pregnancy found, the pregnancy rate in in vitro embryos was for Batch 2 (43%) with the Pre synch protocol, for the IATF it was for batch 6 (71%) using the Re synch protocol in heifers and cows with this it is concluded that heat detection is effective, the insemination and/or transfer schedules are correct, and adequate fertility parameters are presented. However, in batch 3 in in vitro embryos (23%) using the Re synch protocol, resulting in low bovine pregnancy percentages.
