1. Twelve Shorthorn cows were used for an investigation into the effect of diets low in roughage and high in concentrates on the fat content of milk.2. An experiment was conducted with initial and final control periods. During the control periods all

1. Seven sets of monozygous twins were kept under the same open-grazing conditions for one year. Milks were analysed for fat, solids-not-fat, lactose and total protein contents, and butterfats were isolated at fortnightly intervals for estimation of

1. The administration of 0·5–1·5 kg. sodium acetate to cows in which the milk fat percentage had been reduced by diets low in hay and high in concentrates usually brought about an appreciable improvement in fat percentage. The extent of the respo

CHANGES in analytical characteristics following upon the onset of rancidity in butters and butterfats have been widely studied1–6, with somewhat discrepant results. This is scarcely surprising in view of the number of variables involved, within the
