Hemorrhage Control in Eimeria tenella Infected Chicks When Protected by Anti-Hemorrhagic Factor,Vitamin K

Abstract

Conclusion

1. Administration of vitamin K in the dietary of chicks definitely decreased the mortality in chicks parasitized by E. tenella, a hemorrhage-producing protozoan, since all autopsies performed show the vitamin K-protected birds had a fibrinated core in the caeca, which was in the process of being reabsorbed. 2. Vitamin K-protected birds showed a mortality of only 10% in comparison to 70% mortality in the unprotected group.
