Calsorb Forte®
FORTIFIED CALCIUM BLOCK FOR HORSES ON PASTURE
-
Jenquine Calsorb Forte® lick blocks contain a balanced blend of:
Organic calcium – readily absorbable to support bone strength.
Inorganic calcium – helps neutralise soluble oxalates in the digestive system.
Minerals – iodine, selenium, copper, zinc commonly deficient in soils and pasture
Salt – encourages natural intake and supports electrolyte balance.
Formulated similarly to Bone Formula Forte®, these blocks are ideal for horses that are not handfed, and can be used in stables, yards and paddocks.
-
Perfect for horses in paddocks, yards, or stables and also where daily handfeeding is not practical.
Ideal for horses that are:
Consuming roughage high in phosphorus (e.g., grassy, oaten, or teff chaff/hay).
Grazing on soluble and insoluble oxalate-rich pastures (e.g., kikuyu, panic, setaria, buffel, and other sub-tropical grasses).
Undergoing treatment for gastric ulcers.
At risk of calcium deficiency or showing signs of osteoporosis or "bighead".
-
Organic and inorganic calcium, mineral, salt block for stables and paddocks.
Self-administering: convenient lick block format ensures consistent intake without daily feeding.
Assists bone health: helps prevent and manage calcium deficiency and skeletal demineralisation.
Increases daily calcium intake: especially important in grain-heavy, hay-based and oxalate-rich diets.
Reduces risk of “bighead”: helps prevent nutritional secondary hyperparathyroidism and osteoporosis (only 15% of horses with osteoporosis develop “bighead”).
Supports performance & wellbeing: supports movement, dental health, and overall strength and vitality.
Versatile use: suitable for use in feed bins, paddocks, yards, and stables.
Weather-resistant: doesn’t fall apart or melt in rain.
Available in 4kg or 18kg
Horses grazing high oxalate pastures can lose calcium even when total calcium intake appears adequate. Australian research has shown that blood calcium levels may remain normal while parathyroid hormone (PTH) rises and calcium is mobilised from bone, a process that leads to bone demineralisation, and over time, osteoporosis.
This is why calcium form, bioavailability and utilisation matter, not just how much calcium is fed. Simply adding lucerne or standard supplements is often not enough on oxalate‑rich diets.
