PROGRAM RESULTS
End of Program Testing Results
HIGHLIGHTS
▪ 52% of all Ontario herds participated in the Johne’s program
▪ 26% of herds tested had at least 1 test-positive cow
▪ 5% of herds tested had at least 1 high test-positive cow
CONCLUSIONS
▪ Purchasing cattle, pooling colostrum and group calving are risks
▪ Single herd test does NOT fully define herd status – 24% of herds negative on first test
had at least 1 positive on second test
▪ Calf hygiene is the key to Johnes prevention
▪ High test-positive cow removal is critical for calf protection
RECOMMENDATIONS
▪ Do a Risk Assessment & Management Plan (RAMP) annually
▪ Implement Best Management Practices to prevent calf infection
▪ Use a testing program to establish the extent of herd infection
▪ Allow only cattle from low risk, test-negative herds on your farm
