Eight high-yielding Jersey cows were randomly assigned to two 4×4 Latin squares to study the effects of different dietary fat sources on intakes of dry matter (DMI), neutral detergent fiber (NDFI), and ether extract (EEI) as well as on milk yield and composition. The following treatments were used: concentrate with no added fat (control = C); concentrate plus tallow (T); concentrate plus commercial ruminally protected fat (calcium salts + palm oil; PF); and concentrate plus whole soybean (WS). Both DMI […]
