Abstract Fhis stud) was conducted to determine the effect of three disinfectants on the microbes and hatchabthry ofbroiler eggs. One hundred and ninety-two medium-sized hatchable broiler eggs \\ere divided into four groups with three replications

of sixteen eggs each. Each group of the eggs VIas assigned

each of the follo« ing treatments: untreated. NaOCI, HP2 and KMnO .:HCHO combination (1 '2 . The eggs were incubated for 21 days. Data were analyzed using one-way analysis of variance Il1~I completely
