I am going to switch to rotational grazing and hope to come close to the increase in fertility and pasture that Salatin has. I want to get more pasture growing and get rid of the Bermuda. How hard will this be? The cows really over grazed and hurt the grass. The whole land is irrigated and sprinklers going. Can true pasture out compete Bermuda eventually or will it need to be removed? I don't mind the Bermuda I just think there is better grasses for cows. How should I attack this?
I've lived near massive cattle ranches in both Texas and Oklahoma. Summer grazing is always some improved variety of coastal bermuda, usually Tipton 44 or similar. In Texas, they hayed the summer grass and left it dormant over the winter. Half their land was permanent coastal pasture and half they plowed and planted rye grass and wheat or if the winter was mild, rye grass and oats. (Oats freeze easier than wheat.)
In Oklahoma, one neighbor poisons his coastal to burn it to the ground and then overseeds it, probably with rye grass but at least once with some kind of flower mix.That could be some conservation program they run in Oklahoma. (They have a lot of grant programs for plasticulture, hoop houses, pasture, wildlife, ponds, etc.)
Our pasture here is a mix of coastal bermuda, common bermuda, bunch grass, native grasses, and maybe an unknown number of other grasses, clover, some weeds. It grows all year long. Coastal only thrives during warm and hot weather. The rest of the year it is dormant (although if you don't graze if off or mow it or hay it there will be roughage that can be grazed over the winter).
The other grasses take turns growing during their favored seasons and where they do better. Coastal grows thick and crowds them out in some areas of the pasture, but not in others. You almost can't get rid of it because it has
roots very deep.
Improved bermuda grasses are planted by sprigging which is basically taking the grass, chopping it up in pieces and semi-burying it in the ground by disking or plowing over it, using a sprigger (like a manure spreader) or sticking it into plowed ground. So plowing it makes it spread.
Better varieties of common bermuda are now available and it can be planted using seed or used in pasture mixes. Common is more drought resistant, can be overgrazed and survive, but produces less grass that is shorter and not as suitable for haying.
Note that some varieties of grass including an improved giant bermuda require heavy fertilization or they will die out. Useful resources:

How to plant year round pasture

https://www.groworganic.com/premium-horse-pasture-mix-irrigation.html NOT ORGANIC, but is non-GMO $4.99/lb
https://www.groworganic.com/o-livestock-pasture-mix-irrigtd-lb.html ORGANIC $12.99/lb 25-30 lbs/acre - may want to AVOID for horses - contains Fescue
Note that whatever mix you plant you should research each type of grass because some are not suitable for other types of grazing animals. For example, pregnant mares are typically removed from any pasture containing fescue as it can cause miscarriages and difficulty foaling. See

Many grasses that are used for cattle are bad for horses such as haygrazer, Klein grass, and other grasses of that type. They cause kidney failure if enough is consumed and irreversible damage. One gelding that was fed this type of hay over one winter could no longer retract his penis after that winter.
The way it was discovered Klein grass is eventually toxic was when horses that had grazed it for years and been fed the hay off of it for years started having neurological issues and then dying. With those types of grasses, horses may tolerate them in small quantities, but the toxins are cumulative and eventually cause damage.
Remember that even if you never plan to run any other kind of animal, plans can change. You might decide to
sell, and what grasses you have will limit who can buy it. Or you might find the love of your life and she might have horses.
