Abordagem terapêutica de endometrite em central de reprodução equina

Abstract

Endometritis is the main disease that affects the reproductive performance of mares, causing infertility or underfertility. Physiologically, inflammation of the endometer of the mare occurs in order to promote cleansing after reproduction. However, it is necessary for this process to dissolve quickly because its persistence directly affects fertility rates. The accumulation of uterine fluid is the main sign of endometritis, but it is not an absolute factor. What actually defines the development of endometritis is the competence of mares to quickly eliminate the contents of the uterus and fight any infections. Endometritis can involve several etiological agents and have an infectious or non-infectious character, and an association between the two forms is commonly observed. The present study consisted of the observation of the reproductive and therapeutic management of 40 mares (n=40) of the Mangalarga Marchador breed, stationed in an equine breeding center in the south of Minas Gerais. The repetition of heat and the presence of uterine fluid were the main diagnostic markers in the study and uterine lavages represented the basis of the treatments implemented. In all, 82 lactate ringer lavage therapies were performed (73%) distributed in 62 cycles (21%) involving 25 mares (62.5%). The use of antibiotics and antifungals was necessary in the treatment of infectious endometritis, the washing of the uterus was combined with the infusion of drugs (hydrogen peroxide, DMSO, ozonated oil and acetic acid) and the use of antibiotics (Ceftiofur, Enrofloxaxin and Sulfadoxine) or antifungals (nistatin and Itraconazole) based on the culture test (40%). Therefore, the ideal therapeutic management is one that aims to treat each mare individually to prevent or interrupt this pathologic process. The results obtained in this work allowed a parameter of the use of various therapies for endometritis in the reproductive routine. However in-depth evaluation of the intrinsic and extrinsic characteristics involved in each mare is necessary to allow a reliable analysis of the efficiency of the treatments used.
