Developer diets typically contain higher levels of vitamins and minerals than those fed to market animals since the nutritional requirements for growth and reproduction are different. 因为生长和繁殖期营养需要量不一样，后备母猪日粮比商品育肥猪日粮含有更高水平维生素和微量元素。
The higher levels of vitamins and minerals are designed to enhance body reserves of nutrients since breeding animals will remain in the herd for a significantly longer period than market animals. 因为种猪比育肥猪喂养时间长，高水平维生素和微量元素能够确保它们体组织营养物贮备。

Locomotor problems are a common reason for culling and it is important to ensure adequate intakes of calcium and phosphorus. 运动问题是造成母猪淘汰主要原因, 但它对确保母猪能摄取足够钙磷也非常主要。
Several research trials have indicated that the calcium and phosphorus requirements for maximal bone mineralization are higher than the requirements for maximal growth rate. 很多试验研究表明，猪最大骨质矿化要比最快生长率对钙磷需要量更高。
Diets fed to replacement gilts should be at least % higher in calcium and total phosphorus than diets fed to market animals beginning at approximately 50 kg body weight. 从50kg体重开始，%。

In addition to higher levels of calcium and phosphorus, there is antidotal evidence that supplementing the gilt developer diet with higher levels of copper, zinc, iron, iodine and manganese will increase body reserves of these minerals and may enhance future reproductive performance. 后备母猪日粮除要求额外高水平钙、 磷之外如能再补充高水平铜、 锌、铁、碘、锰微量元素，这将 有利于提升母猪体内对这些矿物 质贮备从而能改进以后繁殖 表现。
