Vitamin K Help for Farm Animals

Clinical studies suggest that vitamin K1 supplements can be effective treatment for sweet clover poisoning in calves. Moldy sweet clover hay can form high concentrations of a natural anticoagulant called dicumarol. Farm animals that consume the hay are at risk of developing hemorrhagic disease.^(125, 126)

Vitamin K injections may also help dairy cows suffering from:⁽¹²⁷⁾

• Sweet clover disease
• External trauma (as noted with bloody milk)
• Vitamin K deficiency

Vitamin K3

Vitamin K3 was also tested in calves as a treatment and in steers as a preventive feed additive. However, it was found to be ineffective at both treatment and prevention of sweet clover disease.^(125, 128)

Adding vitamin K3 to feed may help maintain healthy bones in chickens. In a field study, between 2-12 mg per kilogram of feed increased bone volume.⁽¹²⁹⁾
