*SMALL GRAINS: About two‐thirds of total forage production in a "graze‐out" program occurs after mid‐March. Each ton of forage should produce about 40 to 45 lb of cattle gain under normal conditions. SORGHUM/SUDAN PASTURES: Each ton of forage should provide one cow or two calves with about two weeks of grazing. |
