<![CDATA[The objective of the research was to find out the effect of Curcumma, Zn-proteinate, and Cu-proteinate supplementation on subclinical mastitis status in term of 4% FCM milk production. The research was conducted using 24 heads of lactating dairy cows in Randomized Block Design with six treatments, and four groups of milk production as replication i.e. I= >14 kg/day ; II= 12-13.99 kg/day ; III= 10-11.99 kg/day; IV= <10 kg/day. Treatments were: R1 (Control); R2 (R1 + 2% Zn proteinate); R3(R1 + 2% Cu-proteinate); R4(R1 + 2% Curcumma); R5(R1 + 2% Zn-proteinate + 2% Cu-proteinate); R6 (R1 + 2% Zn-proteinate + 2% Cu-proteinate + 2% Curcumma). Parameters observed were 4%FCM milk production and subclinis status. The results showed that ration supplemented with Curcumma, Zn-proteinate, and Cu-proteinate decreased mastitis subclinic status and 4% FCM milk production increased significantly. Supplementation of Curcumma, Zn-proteinate, and Cu-proteinate resulted is the best for decrease in subclinical mastitis indicator and increase 4% FCM milk production.
