I personally wouldn't dose with any livestock, because I don't see how it's any different than fish, JMO.
If they do die, I would REALLY re-dose multiple times before buying anymore livestock. If I had been in your position, I wouldn't have bought livestock. That ammonia didn't convert fast enough for my liking.
All you can do when you get home if they're alive is monitor your levels closely and PWC when needed. When all your levels work out stock slowly and feed lightly.
