Just recently rotated a herd of cows off big bluestem and Indiangrass pasture. Grazed 60 cows on this 9 -ac field twice this season.
• First rotation: June 23rd – July 1st
• Second rotation: August 30th – September 5th.
This last grazing cattle were removed a little early to leave some additional winter cover for wildlife. For this area it is recommended to pull livestock off native warm-season grasses by end of August or early September. Giving these pastures at least 4 to 6 weeks of rest before the first frost ensures the roots have enough time to rebuild carbohydrate reserves for winter survival and strong spring growth.
Native grasses like these truly shine during hot, dry summer months. As C4 plants, they have much higher photosynthetic efficiency compared to C3 cool-season grasses like tall fescue and orchard grass. Thanks to their deep root systems, they are exceptionally drought-tolerant and use far less water to produce quality dry matter.
Both big bluestem and Indiangrass provide highly palatable, nutritious summer forage for cattle. In fact, feeding trials show steer gains of 2.0 to 2.5 lbs. per day throughout the summer!
Best of all, unlike KY-31 tall fescue, native warm-season grasses don't contain toxic endophytes that cause performance losses and health issues. Switching cattle to native pastures during the hottest months helps significantly cut down on heat stress and keeps the herd thriving!
