1. A method for determining effectiveness of an administered drug using auscultation analysis, said method comprising: conducting auscultations to record auscultated sounds from a group of animals, the auscultations including generating lung categories corresponding to a range of health conditions, and each auscultation conducted generating a lung category indicating a categorized health condition for each animal at the time of auscultation; recording a type of drug administered to the group of animals; recording fatalities for the group of animals over a designated time period; conducting a statistical analysis to determine whether there is a statistical difference in case fatality rates between lung score categories; and analyzing the statistical analysis to determine a relationship between fatality rates as a function of lung scores to determine effectiveness of the drug.
