Feedlot segment

Article Abstract:

Computer simulation of the feedlot component of a beef production system was used to assess feedlot and carcass value of purebred and two- and three-breed rotational crossbred cattle populations. Biological efficiency, measured as feed utilization efficiency, and economic efficiency, measured as the dollar cost of weight gain, were determined. Crossbred cattle with Charolais and Simmental lineage exhibited the best performance in terms of biological and economic efficiency. Other crossbreds showed improvement over the purebred cattle in terms of biological and economic performance indicating that cross breeding improves feedlot performance in beef cattle.

Integrated system

Article Abstract:

Integrated cow-calf-feedlot production computer models were used to evaluate the performance of five breeds of cattle and their crossbreeds in terms of biological and economic efficiencies. Biological efficiency was estimated using feed utilization efficiency while economic efficiency was approximated by the dollar cost of weight gain. Analysis of the model indicates that crossbreeds with Angus, Hereford, Charolais or Simmental lineage have superior performance over the purebreds and the other crossbreeds. Although cross breeding increases the energy requirement, the improvement in production efficiencies offsets this drawback.

Cow-calf segment

Article Abstract:

Computer simulation of the cow-calf portion of an integrated beef production system was used to assess economic and biological efficiencies of purebred and crossbred cattle. Biological efficiency was measured as the feed utilization efficiency while economic efficiency was measured as the dollar cost of growth. Five breeds were used to produce purebred populations and two- and three-breed rotational crossbred populations. Analysis of the model revealed that purebreds were the least efficient both in biological and economic performance while crossbreds with either Angus or Hereford lineage were the most efficient.
