It is not often pointed out that genetic modification has not yet been employed to increase crop yields. Primarly because it has not been necessary - yet.

Should also be better for reducing parasite load in the cattle...
Hardly.
This is not a "new" system by any stretch. Cattlemen did this type of thing long, long before these newcomers in No. Dak. came on the scene.
In most cases it means that the cattleman has to dig up the capital for miles and miles of expensive fencing to make it work. Hence, some do and some don't, depending on a lot of things.
This is new? We did this 35 years ago on our family farm. It's just common sense.
I do something similar to this on my couch so I don't put a big divot on any one cushion.
Bull!
Management intensive rotational grazing is as old as the hills. It mimics nature when nature still had preditors. Herds of ruminants bunched together, ate and trampled grass, and moved on to let the grass recover. Actually ruminants and grass co-evolved to suit each other's needs.
Allan Savory's book "Wholistic Management" is a good source. Also Andre Voisin's books such as "Grass Productivity". Not new books!
The BLM has truly made a mess of things.
To raise livestock you just need to be a grass farmer. If you raise and manage quality grasses, the animals do the rest all by themselves. I pasture about 100 acres and hay another 100.
To fence a perimeter costs about $3.50 per foot if you do it according to my farmowners insurance policy, a permanant fence (not just high tensile electric) with woven wire and a hot wire 6" below the bottom of the woven wire and three hot wires above the woven wire and one hot extended three inches from the fence to prevent animals from leaning on it. Interior pasture sections which need to consist of at least sections small enough to force 20 animals per acre. Those paddocks cost about $1.25 per foot to build. Next you need gates and a couple well trained livestock dogs to move the stock constantly and you need to check on the residue for overseeding and noxious weed control.
I could easily spend $50,000 for fencing which will last 20 years tops. About $2,000 every year for maintenance.
In the end, it's cheaper to hay as much unpastured land as possible and feed lot your stock. When hay prices spike, turn your stock into fields which have become stockpiled on growth. If hay stays cheap, cut it and bale what you have stockpiled.
The key to successfully raising livestock is to have many feeding scenarios which enable you to select the most economical feed choice of any given month. Filled silos, three cuts of hay, and plenty of emergency pasture is the best way to go if you ask me. Experts in the Ag consulting business are as plentiful as grasshoppers and their advice is usually just as valuable.
This is not New techology. USDA Livestock Specialists have been recommending this technique for ranchers with marginal pasture ground for at least 10 years,, maybe longer.
