Influência do puerpério sobre o proteinograma sérico de caprinos da raça Saanen obtido por eletroforese em gel de poliacrilamida Influence of puerperium on the serum proteins of Saanen goats, obtained by the analysis of electrophoresis on sodium dodecyl sulphate-polyacrylamide gel

Aiming to evaluate the puerperal influence on the proteinogram of Saanen goats, 108 samples of blood serum from 12 goats were collected, and the results were presented at nine times: just after parturition, 1, 3, 5, 7, 10, 15, 21 and 30 days after parturition. Total amount of serum proteins were determined by the biuret technique, and the sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDSPAGE) was used to the protein fractionation. In this last method, 17 protein bands were observed, from which molecular weights varied between 25 KDa and 275 KDa. In addition, it was possible to identify the following protein fractions: immunoglobulin A (180 KDa), ceruloplasmin (115 KDa), transferrin
