In 4 successive years, assays of 4 months each were carried out on natural pasture, involving 120 animals. Sixty of them (E) were separated from its mothers on the 60-75 postpartum day and supplemented with balanced food. The remainder 60 operated as lactation controls (C), without supplement. Under a repeated measures design, both lots were submited to weighings and blood extractions at the 0, 7, 14, 21, 28, 60, 90 and 120 days. At the end, weight was higher in C than in E (158.7±11.7 versus 139.4±11.6 kg, p < 0.05), but there were not significant differences in stress indicators plasma concentrations, such as aldosterone, sodium, potassium, chloride, cortisol, glucose, fructosamine, monocytes, eosinophils, alkaline phosphatase, gammaglutamyl transferase on aspartate aminotransferase. In E, hemoglobin, erythrocytes, hematocrit, gamma globulin and cholesterol lower levels would be attributed to subnutrition, and total leukocytes, neutrophils and lymphocytes higher rates would be attributed to adrenomedullary sympathetic alarms, which did not evolve toward adrenocortical stress.\n Fil: Coppo, J.A. Universidad Nacional del Nordeste., Facultad de Ciencias Veterinarias. Cátedra de Fisiología. Corrientes, Argentina Coppo, J.A. 2004 El propósito del trabajo fue investigar, ante la menor ganancia de peso vivo de los terneros precozmente destetados, si esta práctica provoca estrés (respuesta corticoadrenal), o bien genera alarma simpática (reacción meduloadrenal). En 4 años sucesivos se realizaron ensayos de 4 meses de duración sobre pastura natural, que involucraron un total de 60 terneros experimentales (E), separados de sus madres a los 60-75 días post-parto y suplementados con alimento balanceado. Otros 60 ejemplares operaron como controles (C) en lactación al pie de madre, sin suplementación. Bajo un diseño de medidas repetidas, ambos lotes fueron objeto de pesajes y extracciones de sangre a los 0, 7, 14, 21, 28, 60, 90 y 120 días. Al final, los pesos fueron mayores en C que en E (158,7±11,7 versus 139,4±11,6 kg, p < 0,05) pero no hubo diferencias significativas en las concentraciones plasmáticas de indicadores de estrés tales como aldosterona, sodio, potasio, cloro, cortisol, glucosa, fructosamina, monocitos, eosinófilos, fosfatasa alcalina, gammaglutamil transferasa ni aspartato aminotransferasa. En E, los menores niveles sanguíneos de hemoglobina, eritrocitos, hematocrito, gamma globulinas y colesterol podrían ser atribuidos a subnutrición y las mayores tasas de leucocitos totales, neutrófilos y linfocitos a alarmas simpáticas meduloadrenales, las cuales no habrían evolucionado hacia el estrés corticoadrenal. application/pdf 1514-6634 (impreso) 1668-3498 (en línea) ternero destete precoz alarma simpática estrés calf early weaning sympathetic alarm stress spa Universidad de Buenos Aires.
