  • Virbac Cal-Plus With Biotin




    CAL-PLUS WITH BIOTIN is a calcium, biotin and vitamin supplement for healthy, strong bones and hooves in horses. Specifically, it is:

    • A treatment that promotes the growth and formation of the hoof as well as the integrity of the hoof wall
    • A preventative and remedy for brittle, cracked and broken hooves


    • Horses on grain-based diets or those fed on sub-tropical grasses and hays.
    • Foals, young horses and pregnant mares.
    • Horses with hoof problems, such as cracks, brittleness and separation of the white-line.
    • Racing, working, pleasure and stud horses to prevent and treat deficiencies of biotin, calcium, vitamin A and D.


    • Three forms of calcium and important co-factors – For maximum calcium absorption and uptake.
    • Optimal calcium:phosphorus ratios
    • Combination of calcium and biotin improves hoof quality – By correcting loss of structure on the outside layers of the hoof wall as well as formation of the cells in the inner two layers of the hoof wall.
    • Aids in the prevention of bone disorders, shin soreness and joint injuries related to training or inadequate calcium intake or availability.
    • Sub-tropical grasses such as pangola, kikuyu, buffalo, green panic, para or setania contain high oxalate levels which bind calcium, making it unavailable for horses. CAL-PLUS WITH BIOTIN can provide much needed calcium for any horses feeding on sub-tropical grasses.
