With calcium being inexpensive, oversupply rather than deficiency is usually the problem. As it stands, calcium carbonate (in pure form or as limestone) is used as a carrier for most premixed products (drugs, vitamins, trace minerals, nutritional additives, and even some concentrates). It is even added at the rate of 0.5 percent in soybean meal as a flow enhancer — a fact largely unknown. Thus, most diets usually contain 10 to 20 percent more calcium than the actual target figure used during feed formulation. This causes virtually no problems, if we ignore the cost-price issue, with the only notable exception being that of layer hens.

Whereas most animal diets contain less than 1 percent calcium, layer diets must contain substantially more. Indeed, such diets contain from 3 to 4 percent, only because the formation of each eggshell requires 2 grams of calcium (in the form of about 5.5 grams of calcium carbonate). Thus, maximizing calcium intake is crucial for these animals. Although exceeding 4 percent dietary calcium can cause metabolic disorders (and hence other dietary means are employed to maximize calcium absorption rather than intake), it is the possibility of a calcium deficiency that concerns our discussion here. As it is logical to assume, a reduced calcium intake will cause layer hens first to deplete their bone reserves (with ensuing leg disorders), and then to reduce and eventually cease egg production. All the while, eggshell resistance decreases and cracked egg numbers increase.

Limestone comes from a wide variety of sources and in very different forms and degrees of hardness. Thus, its solubility, availability, and even its concentration in calcium can be unpredictable. For example, calcium concentration varies between 32 and 38 percent. Assuming a typical layer diet contains 10 percent limestone, this translates to a range of 3.2 to 3.8 percent dietary calcium. The difference (0.6 percent) is considered enormous for layer hen diets to be ignored.
