Attention should be paid to the content of available phosphorus in the feed and the appropriate ratio of calcium and phosphorus. Although the eggshell contains less phosphorus (about 20 mg), it determines the elasticity and toughness of the eggshell. Only about 30% of the phosphorus in the feed can be absorbed and utilized. It is usually required that the content of available phosphorus in rations should reach about 0.4%. In addition to the content of available phosphorus, the appropriate ratio of calcium and phosphorus should be taken into account in the configuration of diets. The imbalance of calcium and phosphorus affects the absorption and utilization of calcium and phosphorus. In general, the total phosphorus in the feed of laying hens is 0.6%, the available phosphorus is 0.5%, the available phosphorus in total phosphorus is 80% to 90%, and the ratio of calcium to phosphorus is between 4: 1 to 6 to 1.
