Evaluation of Artificial Insemination Success of Crossbred Friesian Holstein Cow After Foot and Mouth Disease Outbreak

Abstract

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.
