Abstract
Changes"Tn the electrophoretic patterns of serum, glyco-, and lipoproteins in normal (c) and colostrum -deprived (o) calves were studied from birth to 70 days. Serum albumin appeared to fluctuate inversely to gamma globulin concentration. The concentration of alpha globulin was high in both (c) and (o) calves at one day after birth and decreased thereafter while a general increase was noted in beta globulin concentration. An autogenous gamma globulin appeared to develop in the serum of the (o) calves. Four glycoprotein and 3 lipopro-tein fractions were separated and designated I, II, III, and IV with regard to electrophoretic mobility. Glycoprotein fraction IV appeared to be related to serum gamma globulin with respect to changes in concentration. Alterations in the electrophoretic pattern of lipoproteins occurred rapidly with increasing age. The significance of the developmental changes in protein patterns is not known but the fluctuations reflect the rapid physiological development of the young calf.
