Comparative assessment of egg sanitizing agents on the hatchability of kuttanad duck eggs

An experiment was conducted in the Department of Poultry Science, College of Veterinary and Animal Sciences, Mannuthy, Kerala Veterinary and Animal Sciences University to evaluate the hatchability of various sanitizing agents for hatching eggs of Kuttand duck (Anas platyrhynchos domesticus) eggs. A total of 2400 hatching eggs over a period of six weeks was collected for the study. Each treatment consisted of 600 eggs with 100 eggs per replicate. The selected eggs were randomly allotted to the various cleaning methods (dry cleaning, luke warm water wash, glutaraldehyde wash and sodium hypochlorite wash) and were examined for the effect of these treatments on hatchability. The findings of the present study revealed that the the highest hatchability percentage was recorded in eggs washed with sodium hypochlorite (T4) followed by dry cleaning (T1), glutaraldehyde (T3) and luke warm water wash (T2). Statistical analysis of data recorded no significant difference among treatments.
