AVALIAÇÃO DA QUALIDADE DOS OVOS E DESEMPENHO DE CODORNAS JAPONESAS SUBMETIDAS A DIFERENTES CORES DE LUZ NA FASE DE CRESCIMENTO

The objective was to evaluate the application of different and light colors, during the growth phase, on the performance and quality of Japanese quail eggs. The treatments were applied in the growth phases and their influence in the production phase was evaluated. A randomized block design with time subdivided plots was used, and three 21- day cycles were measured. The treatments consisted of lamps: white compact fluorescent, yellow incandescent and blue, white, red and green LED. The variance analysis was performed and, where significant, the Scott-Knott grouping test was applied. In the laying period of the birds, the treatments presented no significant differences (P> 0.05) for the percentage of bark and yolk, feed intake and feed conversion. However, for the clear percentage parameter, there was a significant interaction (P <0.05) between the different light colors and the evaluated periods. The birds exposed to green LED light in the second period had a lower egg white percentage compared to the other light colors and evaluated periods. It is concluded that the use of compact fluorescent lamps and white LEDs can be indicated, which in addition to high energy efficiency does not affect the future productive performance of quails.
