Coccidiosis

Coccidiosis is a disease of fowl caused by a microscopic animal or protozoa and is characterized by diarrhea, unthriftiness and variable levels of mortality. In spite of much research to advance the control and treatment of this disease, it remains the most costly disease of the poultry industry.

Blackhead (Histomoniasis, Enterohepatitis)

Blackhead is an acute or chronic protozoan disease of fowl, primarily affecting the cecae and liver. The disease is present wherever poultry are raised. Blackhead is one of the critical diseases of growing turkeys and game birds. It may cause stunted growth, poor feed utilization and death. It is of lesser economic importance in chickens since they are more resistant, but the incidence in chickens apparently is increasing.

Hexamitiasis (Infectious Catarrhal Enteritis)

Hexamitiasis is an acute infectious disease of turkeys, quail, ducks, chukar partridges and pigeons. Heavy losses have been reported in one outbreak in ring-necked pheasants. Chickens apparently are not affected.
