Abstract:
The experiment was conducted on 375 hybrid (Hubbard Flex) broilers to determine the effect of different colors of LED lights on the productive performance of broilers. One-day-old chicks were randomly distributed into five different treatments depending on the color and intensity of the lights. (Green G24Lux, Blue B24Lux, Mix G-B 24Lux ,White W60Lux, Yellow Y75Lux), with 75 chicks per treatment, Chicks from one group were distributed in three replicates. The average live weight of the birds, the average feed consumption per bird, the feed conversion coefficient, the production coefficient index, the caracass yield rate and meat yield rate at the end of the experiment were calculated for each of the studied treatments. The cost of using LED lamps was also calculated and compared with the cost of the using traditional tungsten and fluorescent lamps. The results showed that there was a significant effect of color and intensity of the lighting on the productivity of the birds. The combination of alternating green with blue G-B TMix LED lighting outperformed other treatments in average live weight, as the average weight was (2846.3) g compared to the birds that exposed to tungsten lamps (2652.8) g. And high conversion efficiency (average conversion factor 1.69 of TMix G-B treatment birds versus 1.78 for TY treatment birds). The Birds of the treatment TMix the alternating lighting achieved the higher caracass yield rate (79.16%), and higher meat yield rate (54.23%), and the highest average productivity index (401). In addition, the use of colored LED lights reduced electrical energy consumption by 91%. It was concluded from this study the efficiency of using alternating of blue and green LED lighting in improving broiler production standards, and reducing the costs of the electrical energy consumption and thus achieving higher profitability.
Keywords: lighting color – productivity – LED lights – broilers.
