Abstract

The effects of dried turmeric (Curcuma longa) supplementation on the egg laying performance and egg quality of White Dekalb layer hens were investigated in this study. Using a completely randomised design with 48 hens distributed to four dietary treatments, each replicated three times, a 56-day feeding trial was carried out at the Nueva Ecija University of Science and Technology – Gabaldon Campus. The treatments were: T1 – 0 g of turmeric per kg of feed (control), T2 – 5 g per kg of feed, T3 – 10 g per kg of feed, and T4 – 15 g per kg of feed. The parameters measured were hen-day egg production, feed conversion ratio, egg yolk colour, egg weight, egg classification, and economic returns. The results showed no significant effect (p > 0.05) in hen-day egg production and feed conversion ratio; nonetheless, hens fed 5 g/kg consistently showed best performance. By the eighth week, hens on a 15 g/kg feed supplementation showed highly significant effect (p < 0.01) in yolk colour and egg weight. Economic analysis showed that, particularly at 5 g and 15 g/kg feed, turmeric supplementation produced higher net returns than the control group. Finally, supplementation of dried turmeric at 5–15 g/kg of feed can improve specific aspects of egg quality and profitability without adverse effect on laying performance.
