Abstract
Multiparous dams were assigned to be bred by artificial insemination or natural service to bulls with terminal traits. Additionally, the cow- calf pairs grazed upland range or sub- irrigated meadow from June 1 to weaning in November. Two weeks aft er weaning, calves entered the feedlot as calffeds. Natural service range calves had the lightest weaning weights, final live weights, and hot carcass weights. Additional days on feed may be required for natural service range calves to reach similar body weights and carcass characteristics as other treatments. Average daily gain and feed conversion was improved in calves that grazed range pastures prior to feedlot entry. Estrus synchronization and artificial insemination may be an effective way to increase body weights and carcass characteristics of calves that graze range pastures prior to feedlot entry.
