In this study samples of the mixed milk from a herd of sheep were taken weekly for analysis throughout a season of approximately 7 months. The following are the mean values obtained: sp.gr. 1·0350, S.e.m. 0·0002; acidity 0·226%, S.e.m. 0·003; fat 8·00%, S.e.m. 0·07; S.n.f. 11·35%, S.e.m. 0·06; and total N 0·920%, S.e.m. 0·007.
Samples were also taken at 2-week intervals throughout the lactation period of six individual ewes of the Rahmany breed and of the same number of the Awsemy breed. The variation in the composition of their milk throughout lactation and also the variation due to individuality are discussed.
