Picloram appears to be nearly innocuous to animals.
The labeling for picloram dictates keeping animals off the sprayed pasture
only if 1 qt. per acre is exceeded at application. If selling meat animals
off of pasture sprayed within two weeks (thereafter no withholding) the
animal should be kept off that pasture for 3 days before sale. Producing
dairy cows are to be kept off 2 weeks after spraying. But the
half life of the picloram in the forage in that pasture may be more than 5
months.

lesson?: any hay or manure, direct or in compost, imported to the farm may
have a biologically active level of herbicide ? test it with a few
seeds or plants before betting a season's crop on it.?
