During 4 seasons (1965-69) a combination of forage resources that would feed a fixed number of streers the entire year was studied. European-Holstein steers were used. During the first 2 years several forages were evaluated with adjustaments in the carrying capacity. During the next 2 years a beef production system, based on the forage plan, was developed. The animals were on the system from 8 months of age until sloughter. Calves born in the spring were kept under similar conditions until the final fattening period; at this point they were fed either hay harvested from the plan or industry by-products.
