Two systems for wintering pregnant, March-calving heifers were compared over two years on a commercial Nebraska ranch. The ranch’s standard management system (CON) included grazed forage, supplement and hay. The alternative system (TRT) relied on grazed forage and higher levels of supplement, with no hay. Treatment effects on weight and body condition changes differed between years. Calves nursing TRT heifers tended to gain more weight. Two-year-old pregnancy rates did not differ. Partial budget analysis suggests the TRT system reduced expense by $7 per heifer, while maintaining a high level of performance.
