Uso do plasma rico em plaquetas intrauterino em égua suscetível usada no programa de transferência de embriões: relato de caso

Abstract

Horse industry is considered one of the most promising sectors for the Brazilian economy, moving around 16 billion reais an year, and being responsible for millions of direct and indirect jobs. Brazil has one of the largest herds of horses in the world, being found in several segments, from establishments aimed at competition to activities in assisted reproduction. Some biotechnologies can be used to optimize the reproductive results of breeding, including Artificial Insemination (AI) and Embryo Transfer (ET), however, excessive manipulation of the reproductive tract has led to an increase in disorders, especially in mares, leading to uterine problems such as endometritis, considered one of the main causes of fertility problems in equine females. The use of alternative biological therapies such as platelet-rich plasma (PRP) has gained prominence for being able to modulate the uterine inflammatory response, pre and post breeeding or artificial insemination (AI).This report describes the activities developed during the period of the Mandatory Supervised Internship of the student Jéssica Tainã Pereira da Silva Dantas, in the routine of an Equine Reproduction Center, as well as a literature review on mares reproduction and reports a case of recovery of embryo in a susceptible mare after treatment with Platelet Rich Plasma (PRP). The ESO was held at the Monte Verde Equine Reproduction Center, Agreste of Pernambuco, from April 5 to June 18, 2021, with a total workload of 420 hours. During the internship, it was possible to develop skills in monitoring the procedures, techniques and handling performed in the routine of an Equine Reproduction Center. The importance of this daily practical training is remarkable, especially in the final phase of graduation.
