The aim of study was to improve of pregnancy rate in Bali cows through use of a combination of eCG from local pregnant mare with PGF2α. 45 Bali cows were injected with 25 mg PGF2α twice 11 days apart and devided into 3 groups: without eCG (Control); patented eCG 400 IU from Folligon (Intervet-Holland) (T1) and eCG from local pregnant mare sera (T2). After the estrus achievement AI was done and 60 days later the pregnancy was evaluated using two dimensional ultrasound. The results indicated non signicant differences (p>0.05) between the T1 and T2 at the pregnancy rate, but both were signicantly better (p<0.05) than controlKey Words: Bali cow, eCG, PGF2α, Time of estrus, Pregnancy rate.
