Example calf starter formulas. Protein, energy, mineral, and vitamin requirements must be met to achieve maximum growth rates. Protein and energy requirements are listed in Table 2. As a guideline, heifers will consume 2.5 to 3 lb. of feed dry matter per 100 lb. of body weight. A and D should be provided to animals of all ages.
Forages are the basis of a feeding program for heifers.
Good quality forage is recommended since it reduces the requirements for supplementation. Excellent hay meets protein and most energy needs for heifers over a year old, but additional grain is needed by younger heifers for energy. Heifers outside in cold weather may also need additional grain. Corn silage provides adequate energy, but additional protein is usually needed. Poor quality forages must be supplemented liberally with a grain mix which provides both protein and energy.
