Poisoning in Sheep from Emory Milkvetch and Nitro Compounds

Abstract

Sheep were fed nitro-containing Emory milkvetch (Astragalus emoryanus) and infused intravenouslv with 3-nitro--1-propanol and 3-nitropropanoic acid. Emory milkvetch and the nitro compounds produced similar clinical syndromes. Nitro compounds, therefore, appear to be the principal toxic constituent in Emory milkvetch.
