Abstract
A method for the rapid electrophoresis on a cellulose acetate membrane of serum proteins from horses, sheep and pigs is discussed. The various main globulin fractions in the serum of these animals were experimentally identified. Normal values for the percentage composition of serum from normal horses, sheep and pigs were calculated. In the horse there was great individual variation in the shape of the β-fraction, assumed to be due to different transferrin types. The mean value for β-globulin of 19.5 % in the horse was higher than for the other two species. The albumin percentage was highest in the sheep and lowest in the pig, 48.5 % and 43.2 % respectively. The sheep had the highest γ-globulin percentage, 22.8 %, while the horse had the lowest with 19.0 %. Finally the values were compared with corresponding figures reported by other authors and the results discussed.
