This method has been used in studying the effect of the individuality
of the hen and of the ration upon the K value of the
egg. It has been found that the K value is not influenced by
the rations used, but that it is a characteristic of the hen. The
rations used consisted of a basal ration of grains with protein
supplements of dried milk, meat and bone meal, soybean oilmeal
and corn gluten meal.
