Bighead & Osteoporosis In Horses

The condition known as 'bighead' was first identified in Australian horses grazing on subtropical pastures in 1974. Since then, it has become widely recognised in horses grazing on buffel, pangola, setaria, kikuyu, green panic, guinea, and signal grasses. These tropical grasses, commonly planted along Australia's seaboards, contain oxalate - a chemical that significantly interferes with mineral utilisation by horses.
