A SYSTEMATIC REVIEW ON THE DEVELOPMENT OF QUAIL OVARY EMBRYOGENESIS (Coturnix coturnix Japonica) UNDER DIFFERENT LIGHTING COLORS

Quail (Coturnix coturnix Japonica) is one of the commercial poultry that is being developed and produced more frequently. Various lighting programs (pre-hatching) on Aves have been carried out to provide an increased biological response, including growth, reproduction, and productivity. The addition of light or the lighting program is also a factor in the growth of Aves which directly plays a role in controlling various physiological processes. The purpose of this study was to review embryogenesis development of the Quail ovary under various lighting conditions. A literature search was carried out systematically through the PubMed, NCBI, and Google Scholar databases using keywords, namely, "embryogenesis development, ovary, quail light color, and lighting”. The articles obtained were selected based on these keywords by setting several inclusion criteria. Papers that do not meet the inclusion criteria are eliminated, and articles that meet the criteria will be analyzed to obtain data. Based on the search results in the databases using predetermined keywords, 500 articles were obtained. All articles were selected based on inclusion criteria and exclusion and obtained as many as 35 articles that met the inclusion criteria. From the results of the research, it can be concluded that giving variations in the colour of lighting for 16 hours affects the development of quail ovaries. Because of the significant effect of lighting and its colour on embryo development, pre-hatch lighting programs should be considered in future studies.
