Comparisons of Pr protein amounts in horse sera have been performed using Mancini et al.'s (1965) immunodiffusion technique. Relative values against a chosen standard of 100 per cent were determined for a total of 435 horses. There was considerable variation between horses, the highest Pr value being 125 per cent and the lowest 50 per cent of the standard. In animals of the same Pr phenotype the mean Pr values were significantly higher (P 0.001) in foals than in mares. In Norwegian Trotter horses the Pr value of Pr NN animals was significantly higher than that of Pr SS phenotypes, whereas the mean Pr values of Pr SS was significantly higher than that of Pr UU Warmblood Trotter horses, the Pr value of Pr SS being 90 per cent and the Pr UU 80 per cent of that of Pr NN. No difference between sexes with regard to Pr values was found
