Figures such as "100 Million Dollar Loss to a Certain Disease" or a "250 Million Dollar Loss to the Production of a Particular Livestock Species" is not meaningful to the average livestock producer. Yet, when statements are made that mastitis costs the average dairyman $1.00 per cow per month or that grubs cost $5.00 loss per infected animal slaughtered, they appear to create more interest. These are figures that no more effect the pocketbook of both the livestock producer and the veterinarian than the large stupendous figures.
