PROTEINS OF RUMINANT COLOSTRUM

Abstract

1. The proteins in the whey of ewe colostrum resemble those obtained from goat colostrum in containing two main electrophoretic components, with mobilities of -2x10(-5) and -3.9x10(-5) cm.(2)sec.(-1)v(-1) in sodium veronal buffer, pH 8.6 and I 0.1, at 1 degrees . 2. Of 32 samples of goat colostrum examined by paper electrophoresis 27 contained the immune lactoglobulin characteristic of colostrum; of 55 samples of cow colostrum all contained immune lactoglobulin.
