Hatchability and hatching time of Arab Chicken eggs With Different Heat Sources

Abstract

This study was conducted to determine the hatchability and hatching time of Arab chicken eggs in incubators with different heat sources. The research was carried out at the Poultry Laboratory of the Faculty of Animal Science, University of Mataram. A total of three hundred fertile eggs were placed into two different types of incubators which were an electric incubator (EI) and an oil lamp heating incubator (OLHI). Each treatment was repeated three times (150 eggs/treatment). The data were analysed using the t-student test. The results showed that the fertility of Arab chicken eggs incubated using the electric incubator (EI) was 85.2% and OLHI incubator was 90.7%. Embryo viability at EI was 85.6% and OLHI was 90.5%. The hatchability of EI was 70.9% and OLHI was 83.8%, and the hatching weight of EI was 29.6 g, while the OLHI hatching machine was 28.9 g, and the hatching time of eggs on the EI incubator was 21.3 days and OLHI was 21.7 days. Different types of incubators had no significant effect (P>0,05) on the fertility of eggs, embryo viability, hatching time, and hatching weight but it had an effect (p=0.043) on the hatchability. In conclusion, the heat source of the kerosene lamp was better than that of an electric heating incubator
