Effects of Marigold Flower and Peacock Flower Meal Supplementation in Layer Diet on Egg Quality and Yolk Color

Abstract

       Egg quality and yolk coloration were investigated following the inclusion of marigold flower (Tagetes spp.) and peacock flower (Delonix regia (Bojer Ex Hook.) Rafin.) meals in the layer diet. The experimental design was completely randomized (CRD), with three treatments and three replicates. The treatment comprised of a standard layer diet (control) supplemented with 1.0% marigold and peacock flower meal. The data were analyzed using analysis of variance, and the mean was calculated using Duncan's multiple range test in a statistical software program. The study discovered that adding marigold flower meal to the diet resulted in a considerably higher yolk color score than the control treatment throughout the first week of the trial. Throughout the eight-week period, the egg color score remained consistently elevated. In week three of the research, supplementation with peacock flower meal can create yolk color differences from the control treatment. Feed intake, hen day egg output, feed conversion ratio per dozen eggs, feed cost per dozen eggs, egg weight, egg albumen height, and egg quality index were all unaffected by either material color. Thus, incorporating 1% marigold and peacock flower meal into the diet may increase yolk color quality. This has no impact on laying hen performance or egg quality.
