This paper aims to compare and evaluate the success of Artificial Insemination (AI) in Crossbred Friesian Holstein (CFH) cattle before FMD exposure and after FMD exposure in the Pujon sub-district, Malang regency based on non-return rate-1 (NRR-1), non-return rate-2 (NRR-2), and Conception Rate (CR). The material used in this study was 215 CFH cows that became acceptors with a single dose of unsexed semen of 100 before being exposed to FMD (T1) and 115 cows affected by FMD (T2) in Pujon subdistrict, Malang Regency, with a Body Condition Score 2.5-3.5 and aged 1.5-8 years and showing signs of estrus. Using the method of descriptive statistics. The percentage of AI success of T1 and T2 based on NRR-1 values showed no significant difference (P>0.05) 77.00% vs 86.96%, NRR-2 values showed no significant difference (P>0.05) 62.00% vs 73.04%, and CR values showed no significant difference (P>0.05) 49.00% vs 46.09%, respectively. Although AI success based on NRR1, NRR2 and CR showed no significant difference (P>0.05), this study found that AI success in cattle not infected with FMD was higher than in cows infected with FMD.
