Abstract

Sex determination of the embryo during the incubation phase is crucial in the poultry industry. This study focused on solving one of the crucial problems during the incubation phase in the laying poultry breeding industry, namely determining the sex of the embryos. The early stages of research will focus on collecting primary data on heart rate as a non-invasive method and folowed to the specific response to the embryonic development of the Japanese quail (Cortunix japonica) to determine the sex of the embryo during incubation period. As the animal model, we use the layer strain of the Japanes Quail (Cortunix japonica) since they are easy to handle and produce continuous eggs. The quail represents the small types of laying avian species that are economically important as egg producers in some Asian countries. We incubate the Japanese quail eggs and measure the embryo’s heartbeat on day 7 in the 37 ℃ and variety of the temperature measurement. We found the significant correlation between heart rate to the environment temperature. This indicate that embryo has an ability to adjust their metabolic rate depend on the environmental condition. We also found the different patterns of the embryo’s heartbeat based on their sex. The clear difference between male and female shows on day 10, and this difference continues until one day before hatching. The results of this study contribute to the information related to the embryonic response to changes in ambient temperature during the incubation period of small birds represented by quails and could be used as starting point to investigate the various species especially the avian layer strain such as leghorn.
