The perinatal phase of foal development is one of the most challenger period for the immune system. The present study has analyzed serum protein profile, considering variables related to immunity in foals at the perinatal phase, verifying passive immunity transfer. The group 1 (G1) contained eight foals evaluated one day after weaning, and group 2 (G2) included twenty foals at more than thirty days after weaning. Total protein concentration was determined by means of refractometry. The concentration of serum proteins was determined through sodium dodecyl sulphatepolyacrylamide gel electrophoresis. Results were submitted to analysis of variance and Tukey test (P<0.05). IgA concentration showed difference (P<0.05) between the two studied groups, however data were within adult healthy horses normal values. IgG didn’t show statistical difference (P>0.05). The cellular immunity establishment occurs in the neonatal phase, in foals that suckled colostrum and milk properly. The present study showed differences in serum protein profile, considering variables related to immunity, in foals immediately after weaning comparing to foals at more than 30 days after weaning. According to the observed values, we conclude that foals, even early weaned, showed proper passive immunity tranfer. |
