Jenquine Bone Formula Forte

Jenquine Bone Formula Forte is a fortified calcium supplement formulated to support bone health and help correct dietary calcium imbalances in horses on hard feed, grain, hay and oxalate-containing pastures.

Developed by equine veterinarian and nutritionist Dr Jennifer Stewart, Bone Formula Forte combines organic and inorganic forms of calcium. The organic calcium provides an absorbable source of dietary calcium, while inorganic calcium helps address soluble oxalates that can interfere with calcium availability.

Horses fed diets high in phosphorus or low in available calcium may be at risk of calcium imbalance. This can occur with grain and bran-based feeds, grassy or cereal hays and certain subtropical pastures, including kikuyu, panic, setaria and buffel grass.

KEY BENEFITS

• Fortified calcium supplement for horses on hard feed
• Unique combination of organic and inorganic calcium
• Supports healthy bones and skeletal strength
• Helps increase dietary calcium intake
• Suitable for horses consuming high-phosphorus or low-calcium feeds
• Particularly useful for horses grazing oxalate-containing pastures
• Suitable for horses fed grassy, oaten or teff chaff and hay
• Provides additional nutritional support where calcium availability may be compromised
• Formulated and made in Australia

WHY CALCIUM BALANCE MATTERS

Calcium is essential for normal bone structure as well as important body functions including muscle contraction, nerve function and blood clotting.

Some feeds and pastures can reduce the amount of calcium available to the horse. Oxalates found in certain grasses can bind with calcium, while grain and bran-based diets may contain relatively high levels of phosphorus. Over time, an inadequate supply of available dietary calcium can contribute to bone demineralisation and nutritional secondary hyperparathyroidism, commonly known as “bighead”.

Bone Formula Forte is designed to provide additional calcium for horses whose diet may otherwise leave them short of available calcium.

FEEDING DIRECTIONS

Scoop contains approximately 25g.

Weanlings, yearlings and ponies:
• Improved pasture/lucerne: 25–50g daily
• Other diets*: 50–75g daily

Pregnant and lactating mares and mature horses:
• Improved pasture/lucerne: 50–75g daily
• Other diets*: 75–125g daily

*Other diets include grass, grains, bran, pollard, cereal chaff/hay and oxalate-containing pastures.

Feeding rates may vary according to the horse’s diet, season and veterinary or equine nutrition advice.

IMPORTANT

Calcium requirements depend on the horse’s complete diet. Horses showing signs of lameness, bone or dental abnormalities, facial swelling or suspected calcium deficiency should be assessed by a veterinarian.

Frequently Asked Questions

What is Jenquine Bone Formula Forte used for?

Jenquine Bone Formula Forte is a fortified calcium supplement designed for horses requiring additional dietary calcium, particularly horses on hard feed, grain or hay-based diets and horses grazing oxalate-containing pastures.

What is the difference between organic and inorganic calcium in Bone Formula Forte?

Bone Formula Forte contains both organic and inorganic forms of calcium. The organic calcium provides an absorbable source of calcium, while the inorganic calcium is included to help manage soluble oxalates present in some feeds and pastures.

What grasses can interfere with calcium availability in horses?

Oxalate-containing subtropical grasses such as kikuyu, panic, setaria and buffel grass can reduce calcium availability. Horses grazing these pastures may require careful dietary calcium management.

Is Bone Formula Forte suitable for horses fed grain?

Yes. Jenquine recommends Bone Formula Forte for horses fed grain or bran-based diets and other feeds that may be relatively high in phosphorus or low in available calcium.

Can Bone Formula Forte be fed to young horses?

Yes. Manufacturer feeding recommendations include weanlings and yearlings, with the feeding rate adjusted according to the remainder of the diet.

Can Bone Formula Forte be fed to pregnant or lactating mares?

Yes. Feeding recommendations are provided for pregnant and lactating mares. Their calcium requirements can be substantial, so the complete diet should also be considered when determining an appropriate feeding program.

How much Jenquine Bone Formula Forte should I feed?

Manufacturer feeding rates range from 25g to 125g per day depending on the age and type of horse and whether the diet includes improved pasture/lucerne or other feeds. The supplied scoop holds approximately 25g.

What is bighead in horses?

“Bighead” is a commonly used term for nutritional secondary hyperparathyroidism associated with prolonged dietary calcium imbalance. Horses suspected of having calcium deficiency or bighead should be examined by a veterinarian.
