Excerpt from The Effect of Feeding Different Amounts of Calcium and Phosphorus Upon the Growth and Development of Dairy Animals Very little experimental work has been reported concerning the effects of rations low in calcium and phosphorus upon growing dairy animals. Eckles and Swett (1918) found that a dairy heifer when fed a ration low in calcium made normal growth up to eighteen months of age, but that she then became stiff in her joints and could get up only with the greatest difficulty. Rose (1912) found that dairy cows receiving a low phosphorus ration for four weeks became stiff in the joints and decreased in milk flow. Salmon and Eaton (1925) were unable to increase the growth of heifers by the addition of bonemeal to the ration.
