Abstract

The research aim is to study the role of dipping duck hatching eggs with cherry leaf extract as a natural sanitizer on hatching performance and eggshell bacterial counts. A number of 533 Alabio duck hatching eggs were used in this study. Hatching eggs produced from The College of Vocational Studies IPB University; were collected three times a day. Five hundred thirty-three hatching eggs were divided into five treatment groups. The first group was as control, the second was dipping into commercial disinfection, and the third and the fifth group were dipping into cherry leaf extract with concentrations 250 ppm, 500 ppm, and 750 ppm, respectively. The results showed eggshell bacterial counts from cherry leaf extract 750 ppm is not significantly different from commercial disinfection treatment. The bacterial count is lower than other treatments. The dipping treatment of 750 ppm cherry leaf extract in Alabio duck hatching eggs resulted in the lowest embryo mortality and the highest hatchability compared to other treatments. The highest hatchability percentage was in the cherry leaf extract treatment of 750 ppm (90.9%) and the lowest was in the control (75.2%).
