I thought it was outlawed in the states too. Isn't Monsanto the only ones that make it?
I hate the stuff. Maybe I wasn't a good enough manager to keep up with the needs of the cattle but it make my cows jumpy amound other things.
They got calases(sp?) beside the tail head from the shots, they started kicking when I walked behind them, and my conception rates in 4 yr olds droped drastically. Maybe I wasn't keeping up with them nutritionally...who knows. But the cost of each dose, the increase in the feed bill, and the handling problems were in no way worth the hassle of 20 lbs of milk per cow.
