동물(젖소) 건강 Monitoring System 모델 개발 II. 동적인 모집단(젖소)의 질병 발생빈도 예측 측정 방법에 대하여

Development of a Model for a National Animal Health Monitoring System in Gyeongnam II. Methodological Issues in the Estimation of Frequencies of Disease in a Prospective Study of Multiple Dynamic Population

We are proposed for the computation of disease frequency measures and of their associated variances from data collected through prospective study of multiple dynamic cohort (herds) with a National Animal Health Monitoring System (NAHMS) in Gyeongnam. We can be estimated and calculated the annual incidence density for a group of herds and the 1-month risk of disease from the same within herd measure of monthly incidence density. We are proposed that the choice of measure to be estimated depend on the intended use of the information. From results in this study, Our study demonstrate that risk estimates are appropriates for producers and clinic veterinarian making decisions at the animal or herd level. Incidence density measures are appropriate for extrapolation to reference populations used for state and regional-level decision making.
