Última PROFITABILITY OF ESTABLISHING BASIN WILDRYE FOR WINTER GRAZING AgEcon May, Gary J.; Van Tassell, Larry W.; Smith, Michael A.; Waggoner, James W.. This study examined the economic viability of establishing basin wildrye for winter grazing. Mixed integer-programming models were developed that minimized cow feed costs. Estimated basin wildrye establishment costs were $154 per acre. Break-even basin wildrye yields were approximately 2.6 and 2.3 AUMs/acre for March and May calving scenarios, respectively.

Ano: 1999 URL: http://purl.umn.edu/35727 OPTIMAL FEED COST STRATEGIES ASSOCIATED WITH EARLY AND LATE CALVING SEASONS AgEcon May, Gary J.; Van Tassell, Larry W.; Smith, Michael A.; Waggoner, James W.. Integer programming models were used to examine optimal monthly feeding strategies and costs for March and May calving alternatives. Body condition scores were allowed to fluctuate throughout the year except for calving and breeding periods. The May calving strategy decreased annual feeding costs by $20 per cow.
