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 firstly examines the international beef market, then the concept of economic surplus and the effects of the collection of additional animal health information on the aggregate beef supply curve. The effects of movements in the beef supply curve on domestic producer and consumer...

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...

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...

There has been mounting environmental criticism of the livestock industry. Ruminants such as cattle have been implicated as significant contributors to greenhouse gases and it is argued that it is less food efficient to feed plant matter to livestock rather than have humans consume it directly....

Funds for public programmes for control of animal diseases are limited and especially so in less developed countries. Therefore it is important from an economic point of view to get the 'best value for money' from such control expenditure. After briefly reviewing the economic rationale for...

Developing countries often face severe animal health problems, with a number of endemic diseases, and lack resources to put in place the animal health programs of more developed nations. The social costs including lost trade opportunities as a result of animal diseases often exceed the private...

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 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...
