Abstract

The supervised curricular internship was carried out from October10th, 2016 to December 14th, 2016, totalizing 360 (three hundred and sixty) hours in the Agropecuária Fazenda Água Fria, located in Xinguara-PA, under the supervision of the animal scientist João Carlos Guimarães Giffoni Filho and orientation of Prof. Dr. Jorge Luís Ferreira. Fazenda Água Fria develops beef cattle breeding in the commercial follow-up and production of PO animals, using modern techniques in cost management, animal management and nutrition, with careful zootechnical evaluation and good use of animal breeding tools. Activities related to the breeding season calendar included gynecological examination in bovine females, estrus synchronization protocol, artificial insemination (AI), ultrasonography, follicular aspiration (OPU) and embryo transfer (ET). Activities related to sanitary management of the herd were also monitored, such as neonatal care and update of the vaccination schedule during the National Vaccination Campaign against Foot-and-Mouth Disease. During the monitoring of the activities, technical reports of productive and reproductive performance were conducted, which allowed the analysis of the performance of the animals, serving as a diagnostic of the activity. The analysis of the zootechnical indexes aroused interest in verifying the direct and / or indirect relation in the final marketing price of Nelore bulls PO, which became the final objective of this Course Completion Work, entitled: Factors that influence the price of Nelore bulls commercialized in the State of Pará: A estudy of case.
