KOCHIA"Bassia scoparia is palatable to all classes of livestock. The nutritional value, when immature, is similar to that of alfalfa Stubbendieck et al., 2003). Bassia scoparia can be toxic to livestock and may cause death if consumed in large quantities by cattle, sheep, or horses (Sprowls, 1981). Kochia has been known to cause polioencephalomalacia and photosensitization in range cattle (Dickie and Berryman, 1979). Kochia has been identified as containing saponins, alkaloids, oxalates, and nitrates all of which are toxic substances that seem to be more toxic during times of drought and during seed maturity (Dickie and James, 1983), so caution should be used when using kochia as forage for livestock." -- USDA NRCS Plant Guide
