CURMIYEAST AS SUPPLEMENT IN PUFA- CONCENTRATE FOR MODIFYING PRODUCTION AND QUALITY OF DAIRY COW MILK IN BENGKULU

The objective of this research was to apply curmiyeast technology as feed supplement for modifying production
and quality of dairy cow milk in farms in Selupu Rejang, Rejang Lebong, Bengkulu, Indonesia. There were six
activities that had been conducted: preparation of temulawak (Curcuma xanthorrhiza Roxb) powder, yeast
preparation (then as Curmiyeast), preparation of Concentrate-Polyunsaturated fatty acid (PUFA), PUFAConcentrate application in dairy cows, milk production measurement and milk content analysis. Dry matter
intake (DMI) of the ration (containing of 33 kg natural grass and 1 kg PUFA- concentrate) was 8.04 ± 0.48 kg/d.
Milk production of pre treatment (no PUFA-concentrate) was 8.03 ± 2.68 kg/d, higher as much as 0.6 kg/d than
it was before and post treatment. Milk fat was 4.61 ± 1.72 % and protein was 3.71 ± 0.86 %. Ratio of milk
production to ration dry matter intake was 1.0; while ratio of milk production to PUFA-concentrate DMI was
0.67. It is concluded that Curmiyeast (1.5% curcuma and 1% yeast supplemented in PUFA-concentrate was able
to modify milk production and milk quality of lactating dairy cow.
