Pasture Management for Horses
Greater emphasis on pasture feeding of horses should be made in Australia, as it offers the advantage of considerable reduction in feeding costs in combination with a return to the natural grazing conditions to which horses are well adapted. Grazing horses attain benefits from both the nutritional value of the pasture and from the exercise derived from actively grazing.

What is Bighead?
Nutritional Secondary Hyperparathyroidism (NSH) is most commonly known as “Bighead” and develops as a result of a calcium imbalance within the horse’s diet. During periods of calcium shortage, horses will mobilise calcium and phosphorus from their bones to keep blood calcium levels normal.
When this state of calcium deficiency occurs for a period of time, horses will mobilise so much calcium and phosphorus that their bones become fibrous and weak. It is essential that a horse’s diet is balanced and the calcium to phosphorus ratio must be kept above one part calcium to one part phosphorus.
What are some signs of Bighead?
– Shifting lameness, sore bones and joints
– Ligament and tendon injuries
– Noisy breathing and nasal discharge
– Ill-thrift and harsh coat
– Enlarged/swollen facial bones (ridge over nasal bone)
– Early tiring and a low tolerance for work
– Loose and shifting teeth and difficulty chewing
