I've got grass that doesn't lay down like that. Furthermore, research says save your native grasses for winter stockpile, not the improved. It holds protein content a bit better, and, cows confirm this by hitting it first in the winter. So I have about 75 acres of native stuff I don't graze from August to first killing frost, hoping it will grow a lot in the fall. I leave my cows off of it until about 2 to three weeks after that first hard freeze, and rotate them into the last 20 acres of it about Jan 15, hoping march will see some decent green Texas winter grass in the rested fields. Got a few acres of oat food plots for deer that I also try to strategically graze if opportunity allows, giving a boost here and there.
Also, 30% cooked tubs bring the protein content back up, so a must in my opinion. Stockpile has about 5% to 8% protein content. Cows can usually bring that amount to 8% needed for a maintenance diet by eating 1lb of tub per day. If you are there, feeding cubes is a cheaper way to supplement protein. If you want the cheapest, liquid molasses with mineral supplement added.
Finally, letting cows lose a bcs of about .5 in the winter is not a big deal if they start out 5.25/5.5 or above. Stocking rate does need to be low and I like to rotationally graze my paddocks. Also researching using solar charged electric fence to further subdivide. I rotate cattle about once a month.
I have met a guy at the NRCS who says he never feeds hay, so this method has 'expert' proponents.
But a caveat might be related to soil types. We've got clay loam where I'm at. It doesn't leach nutrients hardly at all and holds water quite well. I think Comanche has quite a bit of sandy soil. Might affect things quite a bit.
