I tested some swamp hay a coupe years back that was much rougher and less green than that. Didn't want to kid myself that it was better than it was so when I took samples I went specifically for poorer looking bales with more bullrushes in them. Tested 7% protein 55TDN - no need to supplement until the 3rd trimester. I was shocked.
More old bottom and some black reeds in the stuff I'm finding now. I expect it to be worse than that but hopefully better than straw. 150 bales to go and I can start swapping out the worst bales with onee w/ more grass.Contracted some bean culls (24 protein, 80 TDN) at a reasonable price. Ration should be more than adequate and I have enough good hay/Greenfeed for calving. We've had almost 2&1/2 inches of rain the last few days - things are looking less dire.
