Application
Vitamin K3 is essential for efficient blood-clotting and to maintain proper bone calcification. Practically Vitamin K3 assists in the treatment of haemorrhagic-type disease ,namely coccidiosis . The lack of Vitamin K3 in chicks infected with Eimeria species sharply increases the rate of mortality and this is true also in case of mild or subclinical infections. Vitamin K3 can also revent the  haemorrhagic consequences brought about by the administration of sulpha drugs and antibiotics which, by suppressing the fermentation of intestinal bacterial flora reduce the endogenous bacterial synthesis of vitamin K. As family Vitamin, sufficient adding of vitamin K3 in feed can raise the healthy level of animal especially under stress condition.
