Research Note: Water Consumption and Fecal Moisture of Laying Hens Fed Wheat Middlings and Corn-Soybean-Alfalfa Meal Diets1

ABSTRACT Hens, housed on the floor and fed a diet containing 89 % wheat middlings (WM) either as mash or pellets, consumed more feed and water than hens fed com-soybean meal-alfalfa meal (CSA) diets with either.15,.50, or.75 % NaCI. Moisture content of the hens ' feces was not affected by mash or pellet processing of the WM diet. Feeding the.75 % NaCl-CSA diet, however, significantly increased fecal moisture beyond that observed with the other treatments. Caged layers fed the WM diet voided more feces (2.6 fold) than did caged layers fed the.50 % NaCl-CSA diet, suggesting that wet litter problems observed in the floor pens of birds fed WM were the result of a greater fecal volume voided rather than a higher moisture content per unit of feces.
