Ok, 29 yrs + of my own personal experience. I have "mowed all my paddocks" every week for years. I keep it at 3" sometimes less. Day before yesterday I mowed the 2 top paddocks at 2 1/2" and left them shut. Yesterday I opened them at noon so I could mow the 2 bottom paddocks at 3". Last nite I closed the top paddocks again. They don't need that much grass now, I save those for after a killing frost for late fall and winter. I have never had a problem BUT I keep is short and mow like a lawn, the clippings are so minimal, this is the key I think to managing a healthier pasture without the worry of founder (been there done that), obesity, been there done that too), and colic...very rare here. Oh, and I have about 17 acres I mow weekly. Takes me about 10 hours on a good rider. Grass clipping are bad, just keep em mowed or don't mow at all unless you have alternative pasture. When they cut hay, it lays, gets fluffed (tedded), then baled mostly within 3-5 days and that's long stem. Mowed grass dries very quickly especially when it is hot and sunny. If it's cloudy or wet, it takes longer. I walk out scoop the grass with my fingers. If what I pick up is dry, they go for it!
