Summary Samples of mixed herd milks from thirty‐two herds were examined for fat, total solids and solids‐not‐fat content over a period of thirteen days. Day to day variations have been calculated. Estimates of ‘allowable variations’ in composition have been made. Sampling requirements for accurate assessment of the quality of a milk supply are suggested. A comparison of the variability of the composition of mixed herd milks from cows under normal indoor conditions, on grass and in the transitional period between the two has been made.
