While monarch butterflies require milkweed to complete their life \ncycle, horses are best served by ignoring the ubiquitous plant. Several \nspecies of milkweed, a well-known perennial plant, cause poisoning in \nhorses and other livestock, usually when more palatable plants are not \navailable.<\/p>\n\n\n\n

Milkweed plants prefer sandy soils and are often found along roadways\n and waterways. They can be opportunistic, thriving in overgrazed areas.<\/p>\n\n\n\n

Plants have erect stems, and most species exude a milky sap from \nleaves and stems when broken or fractured. Plants produce pods, which \ncontain many seeds, each with silky white filaments attached. Both \nnarrow-leafed (1-1.5 inches) and broad-leafed (2.5-5 inches) species \nhave been identified, and the narrow-leafed varieties appear to be most \ntoxic.<\/p>\n\n\n\n

The principle toxin in milkweed is galitoxin, and it is found in all \nvegetative parts of the plant, including the leaf, stem, and root. \nAdditionally, milkweed contains cardiac glycosides, which also \ncontributes to toxicosis.<\/p>\n\n\n\n

Ingestion of as little as 0.1% of body weight\u2014or 1 lb (0.45 kg) for a\n 1,000-lb (450-kg) horse\u2014of narrow-leafed milkweed may cause toxicity \nand death. Clinical signs of toxicity include profuse slobbering, \nincoordination, colic, irregular heartbeat, and violent seizures.<\/p>\n\n\n\n

Because of widespread distribution, milkweed is likely to find its way into paddocks and pastures intended for horses. Like most toxic plants, the best defense against milkweed propagation is a weed-management strategy that includes frequent mowing and application of safe, effective herbicides. Proliferation of milkweed in hayfields is also problematic, as the toxins in milkweed are not lost once plants dry. Hence, contaminated hay is potentially dangerous to horses.<\/p>\n\n\n\n

Have you found milkweed in your turnout area? Can you not rid the \narea of the weed? Is there little palatable forage in the turnout space?<\/p>\n\n\n\n

Horses can be fenced off from the area and fed hay, hay cubes, or hay pellets to satisfy forage requirements. Coupled with an appropriate feed or balancer pellet, horses can thrive on this diet.
