| Summary: | The objective of this study was to investigate the dietary supplement of golden shower (Cassia fistula L.) petals on egg quality and customer acceptance. Sixty Hybrid breed laying hens at 40-week old were divided into 4 treatments, with 3 replicates of 5 laying hens each. Each group was randomly taken experimental diet, supplemented with golden shower at 0, 5, 10 and 15 g/kg for 8 weeks. Intensity of yolk color increased according to golden shower supplementation. The redness score (a*) of yolk from the experimental group, fed with golden shower at 15 g/kg was significantly higher than control group (10.05±0.44 and 6.79±0.94, respectively) (P<0.01). This data agreed with the total carotenoid content in yolk. The highest total carotenoid content was found from the experimental group, fed with golden shower at 15 g/kg (31.86±2.19 μg/g of yolk dry weight). Moreover, the golden shower supplementation did not bring negative effect on acceptance test. On the other hand, the significant higher 9-point hedonic on yolk color from the experimental group, fed with golden shower at 15 g/kg was 7.77 in total of 9.0, indicating that consumers liked yolk color of the experimental group, fed with golden shower at 15 g/kg very much when compared with control group (P<0.01). This study highlights the potential of golden shower petals as a natural colorant that can be beneficially introduced into animal feed to enhance yolk color and contribute satisfy consumer preference. |
