ABSTRACT: Diarrhea has a multifactorial etiology and is one of the main diseases affecting dairy calves, promoting high mortality rates in the first weeks of life. This study aimed to assess diarrhea incidence and clinical aspects, as well as clinical responses to treatment (oral and intravenous) with electrolyte solutions. A total of 40 crossbred newborn calves were subjected to daily physical examination until 25 days. Calves with diarrhea (score 3) and dehydration (8% to 10%) received electrolyte replacement therapy orally or intravenously, according to estimated fluid loss, as well as a maintenance volume (oral). Blood and urine samples were collected between 16 and 24 hours after birth and at 5, 10, 15, 20, and 25 days; in diarrheic animals, these materials were collected immediately after the identification of diarrhea and at 2, 12, 24, and 48 hours after treatment initiation. Globular Volume (GV) and Total Plasma Proteins (TPP) were evaluated, in addition to physicochemical urine characteristics. Failures in the transfer of passive immunity may have contributed to the occurrence of diarrhea in 30 calves (75%), which maintained good body condition with no complications. Urine analysis showed a higher pH in non-diarrheic calves (6.7) compared to diarrheic calves (6.2) (p=0.0029), indicating acidification; higher GV, TPP, and urine density were found for diarrheic calves, with reductions 2 hours after hydration and slight variations up to 48 hours, indicating the effectiveness of hydration and acidosis correction. RESUMO: Diarreia, de etiologia multifatorial, é uma das principais doenças de bezerros leiteiros, com elevada mortalidade nas primeiras semanas de vida. Objetivou-se, neste trabalho, avaliar sua ocorrência, aspectos clínicos e resposta clínica ao tratamento (oral e parenteral) com solução eletrolítica. Diariamente, os bezerros foram submetidos à inspeção física até os 25 dias. Animais diarreicos (escore 3) e desidratados (8-10%) receberam terapia de reposição eletrolítica oral ou intravenosa conforme estimativa de fluidos perdida, e volume de manutenção por via oral. Sangue e urina foram colhidos entre 16 e 24 horas após o nascimento, aos 5, 10, 15, 20 e 25 dias e, dos animais diarreicos, imediatamente após a identificação da diarreia, 2, 12, 24 e 48 horas após o início do tratamento. Avaliou-se volume globular (VG), proteínas plasmáticas totais (PPT) e características físico-químicas da urina. Falhas na transferência de imunidade passiva podem ter influenciado a ocorrência de diarreia, verificada em 30 bezerros (75%), que mantiveram boa condição corporal e não apresentaram complicações. A análise de urina evidenciou pH maior nos bezerros sem diarreia (6,7) em relação àqueles diarreicos (6,2) (p=0,0029), indicando acidificação, assim como valores mais elevados de VG, PPT e densidade urinária, com redução após hidratação e variações discretas até 48 horas, indicando eficácia da hidratação e correção da acidose.
