Abstract
The sensitivity of the pools relative to individual fecal culture was 46% (95% CI 29-63%) and 48% (28-68%) for pools of 5 and 10 cows, respectively. The sensitivity of the pools was lower in pools with low shedders (26 and 24% for pools of 5 and 10, respectively) than in pools with moderate or heavy shedders (>75% sensitivity). Pools of 10 cows are the better option to determine or monitor the herd status. A whole-herd ELISA is the least expensive way to determine the status of individual cows but has a lower Se and Sp than individual culture.
