Calcium Deficiency in Horses Grazing Tropical Grasses
Oxalates are chemicals in tropical and sub-tropical grasses in Australia. They reduce the calcium available from the grass because they prevent calcium uptake in horses. This can lead to bone weakness, osteoporosis and ‘Big Head’. Providing a supplement of bone minerals can reduce the risk of bone weakness when your horse is grazing setaria and kikuyu. Read on to find out more about this increasing common problem and how to help your horse avoid the serious consequences of grazing oxalate-containing grasses.
