This paper examines the development of animal health information systems at the farm, national and international level, with examples of some systems that have been developed. Methods for the assessment of animal health information systems are then examined. This is followed by an outline of the...

This paper develops a method for estimating the value of additional information to the individual livestock producer. In doing so it considers as part of the decision made by the farmer to vaccinate animals against B. bovis the decision to collect information on the health status of his herd...

This paper outlines the use of modelling in animal health with an emphasis on Markov chain models. Models that have been used to predict the incidence of disease caused by B. bovis are then examined. The development of a model that enables the use of age specific seroprevalence data to estimate...

In this paper the role of acquired immunity in disease control is examined with particular emphasis on vaccination against B. bovis. A method is then developed to predict the change in disease incidence that will follow the introduction of a vaccination program. This method involves the...

Outlines a simple linear cost-benefit model for determining whether it is economic at the farm-level to vaccinate or dose a batch of livestock against a disease. This model assumes that total benefits and costs are proportional to the number of animals vaccinated. This model is then modified to...

In this paper the benefits of B. bovis vaccination are valued, and the decrease in expenditure on the diagnosis and treatment of disease determined and valued. The costs associated with the B. bovis vaccination program are then identified, quantified and valued. The effect of changes in disease...

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...

This chapter reviews the methods that have been used for the collection of animal health data then specifically examines three methods of data collection being used in the animal health information system by the Queensland Department of Primary Industries (QDPI). One method of passive data...

Economic studies require accessible accurate data on the occurrence of the disease being examined. In areas where this data is difficult to obtain, serological studies can provide considerable information. Serological data alone does not provide information on the number of cases of disease that...
