Lasater Grassland Beef located in eastern Colorado raises cattle the old-fashioned way. Their sustainable ranching practices produce healthier and better-tasting beef. Equally important is the fact that grazing animals are vital to the environmental health of the Great Plains. Lasater cattleâ€“like the roaming herds of bison once didâ€“harvest grasses, till the soil with their hooves, fertilize the ground and then are moved to fresh pastures, leaving the grazed plants to fully recover. When the pastures are rested (typically 70 to 80 days), the grasses develop to their full potentialâ€“growing extensive root systems that help them survive drought.
