Sampling herds in staggered panels is proposed as a way to increase the precision of estimates of the number of incident cases of diseases in food animal populations. A components of variance model is offered as a parsimonious alternative to the somewhat intractable model underlying staggered-panel sampling. Evaluation of these methods using California National Animal Health Monitoring System data showed a gain in efficiency with staggered panel for seven of the eight diseases studied with little loss in efficiency for the eighth condition. The components of variance model was able to predict the gain in efficiency.
