Summary and Implications

This analysis shows that research pastures contain sufficient protein and in most months energy to maintain a beef cow during the lactation phase of the yearly beef production cycle. Crude protein in comparison to the needs of a 1400 pound lactating beef range from 113 percent to 220 percent of the requirement. Energy in comparison to the same need ranged from 87 percent to 118 percent. Eleven of 36 months evaluated were below energy needs. However, previous research has demonstrated that cattle will have selected forage intake that is 3 percent higher in digestible dry matter.
