The Mandatory Supervised Curricular Internship was conducted under the supervision
of Veterinarian Gervázio Quintanilha Faílde de Azevedo, an autonomous professional,
who provides services in the areas of Animal Reproduction and Production, and under
the guidance of Prof. Dr. Jorge Luís Ferreira. The internship took place from August
13 to October 26, 2018, with a workload of 390 hours. Numerous activities were carried
out in the areas of breeding, animal production, and eventual field surgeries in beef
cattle and dairy cattle in properties located in the region of Araguaína, Tocantins and
in the State of Pará. Among the activities developed, the implementation of programs
(IATF), diagnosis of pregnancy by ultrasonography or transretal palpation,
gynecological examination, andrological examination, selection of matrices, analysis
of reproductive traits in the properties, through the mating season, choice of genetically
evaluated bulls, economic properties, dehorning, castration, among others. The
objective of this study was to analyze the performance of the breeding season and the
influence of genetic variability of bulls on productive and reproductive indexes of the
herd in two properties of Araguaína, Tocantins region. The compulsory supervised
curricular internship is undoubtedly one of the most important steps in the formation of
a professional future, since it allows a very diversified view of the current job market,
as well as the peculiar characteristics of the particular area of activity that the future
professional wants to follow. It was possible to observe with the present work that the
correct understanding of the complex interrelationship between the productive
principles and the application of controls, records and adequate management will be
crucial factors for the adoption of the new Brazilian livestock scenario.
