Abstract
The concentration of urinary and fecal histamine was determined in cattle receiving several types of roughage. Excretion of histamine was markedly dependent upon the histamine content of the diet. Cattle fed corn silage as the sole roughage, a feed high in histamine, showed the highest excretory concentrations (22 [mu]ghistamine/g of feces and 127 [mu]g/ml urine). Much lower concentrations of histamine were found in the excreta of animals receiving grass silage or hay as their roughage ration. It is concluded that excretory values for histamine closely reflect feed intake values, and that histamine does not appear to influence appetite.
