摘要：This paper initially outlines the effects diseases can have on livestock production then describes the development of a method to estimate the production loss avoided due to the control of a disease by vaccination. The method involves estimation of individual production loss due to disease and the number of cases of disease avoided by vaccination. The method developed is then applied to determine the production loss avoided due to vaccination against B. bovis.
