Produção in vitro de embriões bovinos: da OPU à TE revisão de literatura

Abstract

This report reports activities carried out during the immersion of the student in the routine of two companies in the area of bovine reproduction, totaling 420 hours, in the context of the Mandatory Supervised Internship. FertVet Consultoria Veterinária, specialized in artificial bovine insemination, has workplaces spread over dozens of municipalities in the Northeast region, mainly in the states of Sergipe and Bahia. Meanwhile, the company Nordeste In Vitro, operates mainly in the in vitro production of embryos in Sergipe, Pernambuco, Alagoas and Rio Grande do Norte. The student's practices were directly supervised by a veterinary director in each company. Respectively, veterinarians Felipe Costa Almeida and Lucas Carvalho Pereira. The activities carried out focused on the reproductive monitoring of the bovine female, from the diagnosis of the reproductive status through ultrasonography, through the estrus induction and synchronization protocols; fixed-time artificial insemination (IATF), ultrasound-guided follicular aspiration (OPU), in addition to all stages of in vitro embryo production, up to transfer to recipients. In addition to the practices, a literature review of the technical and scientific aspects of the in vitro production process of bovine embryos was carried out. The Mandatory Supervised Internship is a crucial and defining part of the veterinarian training process, when a theory, a practice and aspirations for the labor market are identified. With regard to reproductive techniques in cows, the focus of this work, ESO serves the understanding of general management (step by step) within a farm, of the logistics of a field veterinarian on the way to enter the labor market.
