Abstract

Ducks are often developed by breeders as permanent businesses in the city of Merauke. Duck production starts from hatching selection to Day Old Duck (DOD) production. Until now, the hatching process uses a hatching machine and the status of the embryos is not known for certain. Therefore, this research aims to examine the process of embrio formation and the hatchability of eggs using an automatic hatching machine. The hatching method is carried out by selecting eggs with a shelf life of less than 7 days. Egg cleaning process and egg selection process. The hatching process takes 28 days with a total of 60 eggs. Data were analyzed non-paramatically by Chisquer with mean standard deviation. The results showed that duck egg fertility was 98.33% on day 5, and reached 100% on day 15. Egg hatchability rate was 85.29% on day 28. The average initial egg weight reached 63.12-63.80 grams with an average DOD hatching weight of 58.48 - 59.57 grams. Embryo status on day 4 detected a white dot on the dilated yolk. On the 6th day the organs are visible, the heart and blood. On the 12th day, the eyes, neck, beak and feet were visible. On the 16th day the embryo is covered by feathers and on the 27th day the embryo^s body is complete and waiting for the time to hatch. It is hoped that the results of the study can help breeders in the hatching process using automatic machines with maximum production
