These figures demonstrate a clear trend in optimizing production of beef on reclaimedstrip-mined land. On the same acreage female numbers have been increased, weaningweights have been augmented and although there is some variation, reproductiveperformance has been maintained.Major approaches to achieving these ends have included:- Management intensive grazing principles have been implemented.- A herd health program to minimize disease losses has been further refined- By use of artificial insemination and natural service, cows have been bred to sires thathave the potential to maximize growth and marketability of the end product - weanedsteer and heifer calves.- A program of fencing, fertilization, overseeding and controlled grazing has beeninstalled to maximize efficient forage production and utilization.- Water facilities have been improved to provide for high quality fresh water for cowsand calves.SummaryThis demonstration is a highly visible example to area producers of what can beaccomplished using available information in the most effective manner. It is hoped thiswill lead other producers to adopt techniques to enhance the productivity of theiroperations.46
