Interpretive Summary:

Technical Abstract: In recent years, considerable interest in management of intensive grazing systems has justifiably developed. Studies have demonstrated that use of well-managed rotational grazing systems for beef cow-calf enterprises will allow stocking rates to be increased up to 40% without adversely affecting subsequent reproductive performance of the cows. The use of corn crop residues and stockpiled forages can reduce feeding costs during winter which is the most expensive period for feeding beef. Objectives of this winter sytem are: 1) to supply adequate nutrition; 2) minimize stored feed costs; and 3) maintain soil and forage resources. Management considerations included the type of grazing system, forage and residue nutrient losses, supplemental feed required, weather effects, and nitrogen fertilization required. Two of the winter grazing systems yielded more profit per cow than the winter feeding system.
