Proteínas séricas de potros da raça Puro Sangue Árabe recém-desmamados ou com mais de trinta dias de desmame

Abstract: A fase perinatal do desenvolvimento constitui um dos períodos de vida mais desafiadores para o sistema imunológico dos potros. O objetivo do presente estudo foi verificar o perfil protéico sérico de parâmetros relacionados à imunidade de equinos jovens no período perinatal, verificando-se a transferência de imunidade passiva. Oito animais desmamados há um dia, formaram o Grupo 1 (G1), enquanto vinte animais desmamados há mais de trinta dias formaram o Grupo 2 (G2). A concentração sérica de proteína total foi d… Show more

“…TP, Alb, and Glb serum concentration in foals significantly inferior to those found in mares on the day of delivery are attributed to the immaturity of the foal liver, causing reduced albumin synthesis, and to the fact that immunoglobulins had not reached the peak in the blood, at the moment of evaluation. According to Jeffcott (1974) and Favero et al (2011), after colostrum ingestion, immunoglobulins reach a peak in 18 h and are found in concentrations very close to the serum of the mother. However, Lang et al (2007) observed that 64.7% of the foals that they studied showed higher IgG concentration 48 h after birth.…”

“…Although horses start to develop their immune function in the womb of the mother, their immunity is inadequate when they are born, as they are completely dependent on colostrum ingestion. The high susceptibility of these animals to infections in the neonatal period has been associated with failure in the transfer of passive immunity (GIGUÈRE;POLKES, 2005;FAVERO et al, 2011). Colostrum is the first secretion of the mammary gland.…”

“…As frações α e β-globulinas são compostas por proteínas de fase aguda, e se elevam rapidamente em situações inflamatórias ou infecciosas (Kaneko et al 2008, Favero et al 2011. Equinos com problemas inflamatórios e infecciosos, especificamente enterites, diarreias agudas e inflamações articulares possuem níveis séricos elevados das subfrações α1 e β-globulinas quando comparados com animais hígidos (Carapeto et al 2006).…”
