Avaliação clínica e metabólica de potros nascidos de éguas com placentite

Abstract

Biochemistry, hematologic and clinic evaluation of foals newborn to mares with placentitis assist in identification high risk animals. The first study aimed to evaluate neonatal maturity foals newborn of mares with placentitis. Were evaluated six foals, dividing according to degree of viability and survival were evaluated up to 60 hours: No survivors group (NSG, n=2), Debilitated group (DG, n=2), and Healthy group (HG, n=2). The HG showed longer gestation length (320±2 days) and longer inoculationdelivery interval (20,5±2,5 days). NSG and DG showed delay to sternal recumbency and sucking reflex. The NSG had bradycardia and hypothermia to48 hours of life.. It is concluded that the longer maintenance of gestation after placental injury, better is the fetal maturation, which reflect in better viability and ability to neonatal response. The second study aimed to describe hematologic and biochemistry response of foals newborn of mares with placentitis. Was evaluated 58 neonatal foals, which was divided in Control group (CG, n=22) and Placentitis group (PG, n=36). The placentitis group was subdivided into 3 groups: healthy group (HG, n=12), higher blood concentration of plasmatic lactate group (HLG, n=14), and dysmmature group (DG, n=10). Plasma fibrinogen and creatinine on birth was higher (p<0.05) in DG. In HLG and DG presented elevation (p=0.01) in birth concentration lactate with no reduce in 24hs. It is concluded neonatal foals from gestation with placentitis present several clinic conditions, with different adaptation and neonatal response requiring neonatal evaluation and monitoring to order find metabolic changes immediately and delayed metabolic changes.
