The very best grass I can recommend that will serve as a turf grass and feed for cattle is Bouteloua dactyloides (Buffalograss) [synonym=Buchloe dactyloides].  It grows to a maximum of 12 inches if it isn't mowed and, as a turf grass, requires mowing only a couple of times a year.  If your cows are going to be eating it, it won't ever require mowing.  Additionally, it is very drought tolerant.  We have a How-to Article, Native Lawns:  Buffalograss, that gives you information on how to establish buffalograss as a lawn.  Native American Seeds in Junction (one of our Associates) has a seed mix, Native Sun Turfgrass, that includes 80% buffalograss and 20% Bouteloua gracilis (Blue grama), another short grass (3 to 6 inches) or you can buy buffalograss alone.  Both buffalograss and blue grama are highly nutritious and recommended for cattle feed.  Here is more information about buffalograss and blue grama from the USDA.

There are several taller native grasses that are also recommended for cattle.  Here is an article from the Missouri Department of Conservation and the Missouri Department of Agriculture, Native Plants for Your Farm, that lists several species that are recommended for pastures.  These all are found in or adjacent to Caldwell County and none of them have stickers or burrs.

 Andropogon gerardii (Big bluestem) grows 4 to 8 feet.

Elymus canadensis (Canada wild rye) reaches 2 to 4 feet.

Elymus virginicus (Virginia wildrye) reaches 2 to 4 feet.

Tripsacum dactyloides (Eastern gamagrass) grows 2 to 10 feet.

Sorghastrum nutans (Indiangrass) grows 3 to 8 feet.

Schizachyrium scoparium (Little bluestem) reaches 3 feet.

Bouteloua curtipendula (Sideoats grama) grows 2 to 3 feet.

You might consider using a combination of some or all of these grasses for your pasture/yard.
