The research aimed to study estrus synchronization response on reproductive performance of Madura cattle (i.e. native cattle in Madura Island of Indonesia) with different body condition score (BCS). Field research was conducted using 42 cows which were purposively selected from small holders farmers and grouped into 4 BCS (less than or equal to 2.5, 3.0, 3.5, and greater than or equal to 4.0). Number of cows in each BCS was 9, 12, 12 and 9 heads, respectively, with the average open days of 156.76 plus minus 79.19 days. Synchronization was performed by PGF2 alpha double injection (Glandin, GmB). Variables observed were estrus onset and Non Return Rate (NRR) after Artificial Insemination (AI) followed by pregnancy diagnosis. Result of this research showed that Madura cow had significant problem of low body weight and BCS. The success of estrus synchronization and NRR after AI on each BCS were 77.77, 66.67, 91.66, 66.67% and 66.67, 52.83, 75.0, 66.67%, respectively. Interval from PGF2 alpha injection to estrus onset was 69.55 plus minus 7.28, 64.36 plus minus 8.09, 58.90 plus minus 8.04 and 63.35 plus minus 10.86 hours. All parameters showed non-significant difference.
