   Abstract

 

   Following methods for analysis of positive economic impact of general (crude) animal health at population level are based on com­pari­son (in quan­ti­ty or quality in monetary or prod­ucts measure units) be­tween real productivity (utili­ty) of all animals, opti­mal/potential productivity of healthy and reduced pro­duc­tivity of dis­eased animals. Other methods are based on comparison of production inputs da­ta.

   Productivity benefit of animal health (BENpr) equals to the difference be­tween average productivity of healthy (PROas) and dis­eased animals (PROai) multiplied by number of healthy animals (as) or to the difference between average productivity of all (PROa) and diseased animals multi­plied by number of all ani­mals (a): BENpr=(PROas-PROai)*as; BENpr=(PROa-PROai)*a. Analogical methods can be used for profit/income benefit of animal health.

   Input benefit of animal health (BENin) equals to the differ­ence between average inputs to produc­tion by diseased (INai) and healthy animals (INas) multi­plied by number of healthy animals or to the differ­ence between average inputs to pro­duction by dis­eased and all animals (INa) multi­plied by number of all animals (a): BENin=(INai-INas)*as; BENin=(INai-INa)*a.

    Economic values of animal popu­la­tions and their prod­ucts which animal health services should protect are enor­mous. Effects of suc­cessful eradi­cation programmes last and cumu­late in follow-up periods. Benefit of health is usually much more important than losses due to diseases.  New interna­tional trade policy increases the role of animal health at population and herd levels.
