Among 67 Ayrshire cows, observed frequencies for beta -lactoglobulin phenotype were: AA, 4 cows; AB, 26; BB, 37. These compared with expected frequencies of 4.32, 25.39 and 37.28 resp. Results are presented of analysis of AA, AB and BB milks for total N, non-casein N, casein N, non-protein N, beta -lactoglobulin N and casein index. The 4 AA milks contained most beta -lactoglobulin, and the BB milks least.
