as an FYI you do not need to give the cows Straw or TMR in the pastures. They will live just fine given a few hay and silage bales which in a pasture of 50 keeps 1 bale silage and 1 hay will keep them going for a few days I think like 5 or so. Pastures only need those 2 things. You can also feed them TMR to get the grain up if you like using the creep feeders and overloader wagon. The cows in the pasture do NOT give any milk or manure.
