Vitamin D3 powder supports bone growth and development, participates in calcium and phosphorus metabolism, and provides a fundamental nutritional foundation for animals.
Its role is especially relevant to laying animals, where eggshell hardness is closely related to calcium and vitamin D3 levels.
View Product SpecificationsVitamin D3 participates in calcium and phosphorus metabolism, supports healthy bone development, and meets the nutritional needs of laying animals — providing a fundamental nutritional foundation for animal growth.
Deficiency leads to high rates of broken/soft-shelled eggs, leg diseases, and reduced finished product quality.
Enhances bone development, reduces limb & hoof diseases in breeding pigs and postpartum paralysis in sows, extending reproductive lifespan.
Promotes successful molting and shell hardening in crustaceans, enhances stress resistance and survival rates.
Prevents postpartum paralysis in dairy cows and promotes bone growth and development in calves for improved milk yield.
Real results from Polifar VD3 deployments across poultry, swine, aquaculture, and ruminant operations worldwide.
Lameness & paralysis rate as high as 2.3%; large slaughter weight fluctuations.
Lameness & paralysis dropped to 0.6%; slaughter weight indicators improved.
➤ -74% reduction in leg disease
Rickets, hind-limb weakness; survival rate below 93%; poor daily weight gain.
Skeletal health significantly improved; survival rate rose above 97%.
➤ +4% survival rate increase
High-density farming → stress, soft shells, difficult molting; survival below 75%.
Soft-shell shrimp down >50%; survival rate rose to 88%; product quality improved.
➤ +13% survival rate boost
Tropical summer — soft-shell egg rate up to 7%; decreased egg production.
Soft-shell rate dropped to ≈1%; laying rate rebounded ~3%.
➤ ~$30,000 extra revenue / 50K birds (3 months)
Hot dry climate — reduced feed intake, poor FCR, increased leg softening & lameness.
Lameness & leg disease down 60%; improved FCR; higher slaughter weight.
➤ -60% lameness; improved FCR
Peripartum hypocalcemia — postpartum paralysis up to 8%; reduced milk yield.
Postpartum paralysis dropped below 1%; peak milk yield +2.5 kg/head/day.
➤ +2.5 kg milk/head/day at peak
