The hens were divided into four dietary treatments with six replications of four birds in each group. Birds of three groups were supplemented with 0.1%, 0.2% and 0.3% spirulina and one group was kept as control. Yolk colour significantly improved (P&lt;0.01) as compared to control, without affecting any other production performances. It is suggested that dietary supplementation of spirulina at 0.2 to 0.3% levels in aged laying hens enhanced egg yolk colour.</p><p><em>Bangl. vet</em>. 2017. Vol. 34, No. 2, 71-78</p> ER -
