Faunsdale, AL | You can test it if you want, but it will be OK since you've had the rain. If it's like corn, the stalks will have most of the nitrate accumulation during a dry spell and it will move up the plant rapidly after a good rain. Most of the time the cows will leave the stalks alone and eat the leaves off. Except for the ones they walk down, it will keep putting out leaves on the stalks as well as tillering out around the base if it had adequate moisture and time/heat before frost.
We used to use it for the dairy cows all the time. They ate silage/hay/grain at the barn and then were turned out at noon and night on the sudax, so that could be why we never had any trouble. Also grazed some heifers in some of it. Never had trouble except finding them for a week or two! Always had to call them out to the feed trough so we could count.
After a frost it's very likely you'll get HCN production and it's best to let it die and dry down completely before grazing the dry forage. | |
