Around here some of the dairy guys have tried the shooting in anhydrous in poor hay to increase protien. Not too sure how that is supposed to work. Some bacterial conversion.

What ussually happened is that they fed the hay too soon and the anhydrous shows up in the milk sample. Then if the truck is stopping at small farms everyone on the truck looses their milk load for the day. They might do better in tank testing before loading the truck these days.

In the midwest the automatic Harvestec kits do good if they are kept up. The bales do stay greener and it will prevent mold in big squares. However buffered acid is still very corrosive. The buffereing agentjust slows down the reaction. Seen many balers with the paint removed from the front just below the acid pressure guage. Leave it on your skin long enough and it does burn.
