This report describes the activities developed during a supervised mandatory curricular
internship, carried out from March to May 2020, under the supervision of the MV. Gibson
Insfran da Silva. The activities were developed in rural properties belonging to the
municipalities of Araguaína-TO, Brasilândia-TO, Colinas do Tocantins-TO, Jacilândia - TO,
and Barra do Ouro - TO, and were provided in the area of bovine reproduction. The main
activities developed were implantation of programs Fixed-time artificial insemination (FTAI),
induction of puberty in heifers, diagnosis of pregnancy by ultrasound, or rectal palpation. The
internship spanned the period from 16/03/2020 to 29/05/2020, with a total workload of 416
hours. Also as part of this report, an analysis was carried out on two farms on the reproductive
performance of heifers, whether submitted or not to the puberty induction process. The results
showed that this practice suffers great variation in response, being dependent on numerous
factors and that the properties that choose such a practice must establish well-defined criteria
so that the objectives are achieved and the results satisfactory and economically viable. The
mandatory supervised internship is an extremely important activity for the development of
skills, competences, and ethical and professional responsibility of the veterinary medicine
student.
