Advanced Calcium Metabolism Support

OSTOZET D₃ FS is a scientifically formulated feed supplement containing 1,25-dihydroxycholecalciferol (calcitriol), the active form of Vitamin D₃, along with VDR (Vitamin D Receptor) activity enhancers.

Unlike ordinary Vitamin D₃, which requires two-step activation in the liver and kidneys, calcitriol in OSTOZET D₃ FS is immediately bioavailable, ensuring rapid action on calcium metabolism, skeletal strength, and eggshell formation. VDR enhancers further amplify the biological effect, making the product highly effective even in birds under metabolic or organ stress.

OSTOZET D₃ FS is especially beneficial for high-yielding layer birds during early lay, peak production, and under stress conditions where calcium metabolism is challenged.

Key Problems Addressed

Comprehensive solutions for calcium metabolism challenges

Key Problems How OSTOZET D₃ FS Works Benefits
Poor Calcium & Phosphorus Absorption Upregulates intestinal calcium-binding proteins (calbindin-D28k, TRPV6) and boosts VDR activity. Ensures rapid mineral uptake for strong bones and eggshells.
Weak Eggshells & High Breakage Enhances calcium carbonate deposition in the shell gland with calcitriol + VDR support. Produces stronger, thicker, more uniform shells; reduces cracks.
Hypocalcaemia & Calcium Tetany Raises serum calcium, mobilises bone reserves, and improves renal calcium reabsorption. Prevents tremors, paralysis, sudden death, and leg weakness in early/peak lay.
Embryo Mortality & Poor Hatchability Improves calcium and phosphorus transfer into yolk via VDR-mediated transport. Boosts hatchability, chick quality, and reduces embryonic losses.
Bone Weakness & Osteoporosis Balances osteoblast/osteoclast activity and enhances bone cell responsiveness to calcitriol. Prevents fractures, keel deformities, and cage layer fatigue.
Poor Feed Efficiency & High Phosphorus Waste Improves mineral utilisation efficiency, reducing dependency on excess inorganic phosphorus. Enhances FCR, reduces feed cost, and lowers environmental phosphorus pollution.
Weak Immunity Under Stress Stimulates immune cells via VDR activation, regulates cytokines, and promotes antimicrobial peptides. Improves vaccine response, resilience, and reduces stress-induced immunosuppression.
Stress or Organ Dysfunction Bypasses liver/kidney hydroxylation, ensuring activity even under mycotoxicosis or stress. Maintains calcium metabolism under disease or metabolic challenges.
