Abstract
Four early lactating Nili-Ravi buffaloes were fed four diets either contained no added fat or had tallow, poultry fat
or mustard oil at 3% of dietary dry matter in an experiment conducted in a 4x4 Latin square design. Intakes of
DM, OM, CP, ADF and NDF decreased (p<0.05) in buffaloes fed supplemental tallow or poultry fat than those fed
control or mustard oil. Intake of EE was lower in control and higher in those fed mustard oil. Intakes of NEL and
DE were higher (p<0.01) in buffaloes fed mustard oil versus those on control, tallow or poultry fat. Average daily
yields of milk, FCM, SCM and ECM were higher (p<0.01) in buffaloes fed different fat sources than those on
control. Milk fat percentages and yields increased (p<0.01) with dietary tallow than those fed poultry fat, mustard
oil or control diet. Total solids contents were higher for buffaloes fed supplemental tallow versus those fed the
control, poultry fat or mustard oil diets. The milk protein, lactose, solids-not-fat, ash, specific gravity and GE of
milk fat did not differ significantly ((p>0.05) in control versus those fed fat from various sources, whereas feeding
different sources of supplemental fat increased daily solids-not-fat yield.
