Abstract
Some fatty acid supplements in concentrate containing Curcuma xanthorrhiza, ROXB wereevaluated for effects on milk yield, milk fat and protein, including milk fatty acid. Four lactating (4 ± 1.5months ) Fries Holland (FH) cows were allocated into four treatments of concentrate containing 4.5%palm oil (CP0), 4.5% corn oil (CP1), 4.5% roasted ground corn (CP2), and 1.5% corn oil and 3% roastedground corn (CP3), respectively, in 4 x 4 Latin Square experimental design with 3 d-period. Resultsshowed that there were no significant (P>0.05) effects on milk yield, milk fat and protein, and milk fattyacid. However, the highest average of milk production was found in CP2 (8.63 kg/d). Milk fat wasdecreasing to 3.81% in conjunction with the more potential total PUFA (71.81%) in CP3 with corn oiland roasted ground corn. Ratio of omega-6 to omega-3 in milk was the same in both, CP2 and CP3, itwas 2.14. However , since the objective of this research was to improve milk yield as well as milkcomponents and health concern, therefore the CP2 with roasted ground corn was considered as theoptimal one.
