I think you might be mistaken about that.

I strongly suspect your wrong about something. No offense intended. I've never observed cattle choosing kr over Klein even good Bermuda. The exception might exist if the Klein was very mature and the kr younger but I'm having a hard time imagining what might cause that.Going to try to revive this thread. Hope that's OK.
Got a question about why cattle choose some grasses over others first. Wondering if there is a consistent type of 'succession' to the way cattle pick grasses to eat.
I have a 27 acre 2 degree sloped pasture with:
1) A bit of native stuff growing out of white-chalk caliche soil
2) KR Bluestem growing in the thinner clay loam soil around the upper fringes of the pasture and some of the poorer areas
3) 14 or so acres of thicker Klein grass in the thicker clay loam soil towards the lower side of the slope.
4) Common Bermuda grass in patches around the high-traffic areas like the gates.
The Klein was planted by the fellow who leased it before we took it back over. The KR, native, and common Bermuda are just there naturally.
Even when I had the place leased out at a higher stocking rate, the cattle would keep the native and the KR Bluestem grazed off, but would leave the Klein and common Bermuda. It seems that they prefer the grasses in this order:
1) Native grasses
2) KR Bluestem
3) Common Bermuda
4) Klein
I've researched a bit and it seems that the native grasses are lower dry matter but higher protein, so it makes sense that the cows would eat this 'candy' first. But in this field that 'candy' is growing in some really poor soil! And the next surprising thing is that they go for the KR Bluestem so much over the other grasses. Many folks on this site seem to think the KR is not quality forage, but the cows on my place would seem to disagree.
This baffles me though, because when I was laying 500 feet of PEX for my water trough, the best soil in the field is where the Klein grows. I figured this grass growing in more fertile soil would taste better and have higher protein/nutrient content than the stuff growing out of the caliche or the upper edges of the field, thus making it more desirable to the cows.
But evidently not.
Questions:
1) On your place is there a natural grazing succession like this where the cattle will eat one grass first then move on to the others in succession?
2) If so, does this type of successional grazing depend more on the soil, the cattle's preferences, or the stage of the grass (I know it's probably a combination of the three, but wonder if one factor is more important).
I already know that I can rotate cattle and use polywire to focus grazing, so no need for those suggestions.
Thanks if you respond.
If you want to keep that Klein make it a pasture of it's own. Make it the priority and turn in and out of it based on its needs. Use the KR as a sacrifice or lower priority area. Manage it against itself, not agaisnt the Klein. Same with your natives. If they are that good try to section them off also and turn in and out as needed.Thanks for the comments! After reading everyone's opinions, I think it probably has to do with stage of maturity, mainly. A shorter, early stage KR Bluestem is likely more desirable than a late stage Klein or Bermuda…
When I now think about the history, we rested the place for two years and then put cattle back out there. The Klein in the better part of the field was already very mature, and we didn't mow at all. The grasses in the poorer soil were shorter, and, probably got more light to the ground in spring when green up came. Spring two years ago was really wet. I think more water meant good growth, even in the poorer soils. My guess is that there were more tender shoots in that area so the cows went for it first. Then, as they weren't short of grass, they just kept regrazing the new growth instead of the green Klein that was again over mature with a lot of old brown stuff mixed in.
I have a few polywire reels I'll use to try to encourage more consistent grazing for the coming season. I'll even keep them out of the upper parts of that field until the heavily grazed stuff from last year is mature, then see if they stay focused on the Klein first.
It's not all about nutritional value. Smutgrass is good feed, but cows won't eat it unless they don't have anything else.
We'll, I wouldn't mind seeing the Klein increase, but I don't want bare spots from overgrazing, either. Want to get a feel for what's actually going on. Already fenced off most of the Klein section. Going to graze that pasture (and a few others) differently this year and see what the grasses do and also see if the condition of the cattle suffers or not.If you want to keep that Klein make it a pasture of it's own. Make it the priority and turn in and out of it based on its needs. Use the KR as a sacrifice or lower priority area. Manage it against itself, not agaisnt the Klein. Same with your natives.

They go for palatability for sure. But they do also select for protein I think, especially during the winter. They took all the native stuff first last winter then went to the invasive/introduced, and the stuff I read for central Texas was that native holds up better as stockpile. But then again, maybe that's because the native stays palatable longer…Not sure about any conclusion regarding cows eating what is best or most nutritious for them. Pretty sure that is not true for people. With people, it is what tastes good or makes them feel good. Even if it kills them. Cows may be the same.
I'm in the hill country. Dry but good cattle country.I strongly suspect your wrong about something. No offense intended. I've never observed cattle choosing kr over Klein even good Bermuda. The exception might exist if the Klein was very mature and the kr younger but I'm having a hard time imagining what might cause that.
Johnson grass is always the first to go.
Klein will typically be next along with the true native bluestems. Bermuda depends on it's age rain ,and fertilizer applied but it's typically seems less desirable to cattle and wildlife than Klein. A very modest 30 pounds per acre of nitrogen Bermuda will starve while Klein will flourish and make your cows fat and shiny. It is possible that you have bdahl bluestem very difficult to tell apart from kr. It also goes through a stage where they won't touch it then suddenly 2 weeks later they'll take down the fence to get at it. It's odd how a grass that looks so much like the kr is so much more desirable to both cattle and wildlife. I'm referring to kr vs bdahl. central Texas is a big place. Where abouts are you?
I did mow some of it so hopefully spring will see more pressure on it.1. Yes
2. Stage of the grass
Johnson grass will grow on any type of soil and they will generally eat it first. They like the broad leaves on plants. They like KR just fine but it is such a slow grower, it doesn't provide enough grass per acre to do much good. Lots of native grasses are very palatable when young but get course and stemmy when they mature. Klein looks like it is not being eaten and while it won't be their first choice, they will eat the new growth coming up at the bottom of the bunches and leave the tall stems.
