The study was conducted to determine the effect of marigold (Tagetuserecta L.) and its petal meal on yolk colour and egg quality parameters in commercial layers. One twenty hyline birds (24weeks old) were divided into five groups of four replication each and each replication had six birds each in CDR. The marigold petal meal (MPM) was incorporated in the diet of commercial layers at 0 (T1), 3 (T2), 4 (T3), 5 (T4) and 6 % (T5) levels. The CP content of experimental diets ranged from 16.53 to 18.82 per cent and MPM contained 12.49 % CP and 11.43%EE and 2400mg/kg of petal meal. No significant difference was observed in shell thickness, Haugh unit, yolk index and albumen index between the groups. Significantly higher (P≤0.01) yolk color and xanthophylls content in yolk was observed in T5 followed by T4, T3, T2 and T1. All MPM fed groups had significantly higher (P≤0.01) CP level in egg and egg yolk than T1. But transfer of xanthophyll pigment from feed to yolk was 95.04% in T1 than other groups. It was concluded that up to 6% level of MPM inclusion in the layer diet maintained egg quality parameters as that of control group and xanthophyll content of egg yolk, yolk colour and CP content were higher as the level of MPM increased in the diet.
