Laboratory experiments have shown that the pyrethrins are substantive to cattle skin and hair. When cattle are passed through a spray race, the concentration of pyrethrins in the circulation liquor decreases. The adsorption rate constant has been calculated for standard conditions and an equation derived for calculation of the concentration after passage of cattle through the spray race. The use of this equation in veterinary practice is discussed.
