Growth Performance of Japanese Quail (Coturnix coturnix japonica) Utilizing Different Light Bulb Color

This study was conducted to determine the growth performance of Japanese Quail (Coturnix coturnix japonica) utilizing different light bulb colors in terms of growth performance which include body weight, feed consumption, feed efficiency, average daily gain, and mortality rate. A total of 192-day-old chicks (160 females and 32 males) were utilized and randomly assigned to 16 cages using a Randomized Complete Block Design (RCBD). Four experimental treatments were tested: T1 – yellow (control), T2 – green, T3 – red, and T4 – blue, with four replicates per treatment (10 females and 2 males per replicate). The results demonstrated that LED light color significantly influenced various growth performance metrics. Specifically, T3 – red resulted in the highest body weight, T2 – green led to the greatest average weekly gain, and T4 – blue showed superior feed consumption and feed efficiency. Mortality rates, however, did not differ significantly among treatments. Recommendations from the study include the use of red LED lights to optimize body weight, green lights for improved average weekly gain, and blue or yellow lights to reduce feed consumption.
