We cut our oats before they reach the dough stage. We give up a little tonnage but the quality makes up the difference. Last time I had them tested they ran between 9-10% protein. Cattle love them! I have never had a problem with nitrates but we don't fertilize them and plant them on summer fallow.
We have a good crop also if we can keep the great white combine from getting to them.
You are right about when to cut oat hay, Howdy1. I asked Mr.FH and he
said we USED to cut it in the soft dough stage, but he tries to cut it
earlier for the same reason you mentioned.
We don't fertilize anything or plant on summer fallow and we've still
seen high nitrates in oat hay. If you have high nitrates you can blend
other hay with the oat hay and feed the oat hay last. Ours are usually
stressed from needing water and that will cause high nitrates. However,
one year in SW Montana ON IRRIGATED OAT HAY that had never been
stressed, the nitrates were really high. We had 1400 small square bales
and it took us 3 years to get it all fed. Of course we only had 150-200
head of cows. You just can't be too careful with hay that can have
nitrates and it seems oat hay is the worst. We fed a lot of oat hay
in Wyoming and never tested it, and never had a problem. But that was
in the later 60's and early 70's when it rained more than it does now.
Or we were just plain lucky. :lol:
One thing about high nitrates (and we learned this the hard way)
if you calve in late March, stop feeding it in February so you don't
chance an abortion from the nitrates. You can tell a calf that aborted
because of nitrates by the gums. If they are pale, it was most likely
nitrates. The calf gets smothered and the gums turn white from
lack of oxygen. FWIW
Interesting thread.
