Perfil metabólico de éguas da raça Mangalarga Marchador no periparto e de potros recém-nascidos

Abstract

Gestation in the equine species has been studied in several aspects related to physiology, endocrinology and neurobiology in order to better establish the biological mechanisms and activities related to this phase. There are few studies about the hematological and biochemical alterations in maturation mares of the Mangalarga Marchador breed raised in pasture and in newborn foals. Hemogram and biochemistry are tests that reflect the general state of the animal and the metabolic status of animal tissues. In the gestation physiological adaptations occur, therefore, it is indispensable the knowledge of the changes in the plasma and serum constituents in pregnant mares and the peripartum aiming at the correct evaluation of the exams performed in that period. For this purpose, several metabolic parameters were studied in mares at the final stage of gestation, at delivery and in the immediate postpartum period, as well as newborn foals, aiming to provide nutritional management and diagnosis of common diseases in this period. There were no alterations in erythrocyte erythrocyte mares in the peripartum. Leukogram values are influenced by gestation, lactation and childbirth. The foals presented lower serum concentrations of total proteins and magnesium, and higher albumin, FA, GGT, LDH, ALT, CK, cholesterol, triglycerides, glucose, iron and calcium in relation to the mothers.
