The objective of this study was to investigate the effects, on laying performance, egg quality traits, colour and composition, of supplementing a white corn-based diet with either Desmodium tortuosum leaf flour or Hevea brasiliensis seed meal. Four hundred 32-week-old hens were distributed to 40 pens of 10 hens each and allocated to 10 dietary treatments (4 replicates per treatment) for 6 weeks. Two control groups of 40 hens received one of either diet Y, based on yellow corn, or diet W, based on white corn. The other groups received a diet based on white corn 1) supplemented with Desmodium tortuosum leaf flour at 2.5%, 5%, 7.5% or 10% (diet D) or 2) supplemented with Hevea brasiliensis seed meal at 2.5%, 5%, 7.5% or 10% (diet H). Diet D led to increased egg production with a reduced cholesterol content but a degraded (pale) yolk colour. Diet D improved laying performance and yolk colour at a reduced feed cost per egg, but had no effect on cholesterol content. In conclusion, the inclusion of Desmodium tortuosum leaf flour, in a white corn-based diet, is effective in lowering feed cost, increasing egg production and improving yolk colour.
