The purpose of this study was to determine the dietary effects of fruit pulps (dried tomato, apple and grape) on the performance and egg quality characteristics of laying hens. In this trial, 196 Lohmann sandy layers 25 weeks of age were distributed into four groups with seven replicates for 9 weeks. Trial groups fed following diets, control group basal diet (no additive), 4 % dried tomato pulp, 4% apple pulp and 2.5% grape pulp. Feed conversion rate was not affected by any addition of fruit pulps throughout the trial. The dietary inclusion of dried tomato pulp increased feed consumption, egg weight and egg production and decreased egg yolk malondialdehyde (MDA) levels on day of 1 compared to the control. Egg yolk MDA level was decreased with the addition of 4% tomato and apple pulp to the diet, but increased with the addition of 2.5% grape pulp to the diet on the day of 28. Moreover, the addition of dried tomato pulp to the basal diet significantly increased egg weight and egg yolk yellow color (a). As a result, this study provides evidence that adding up to 4% tomato pulp to diets may be used without adverse effects on laying hens’ productivity and may improve egg quality characteristics by decreasing MDA levels in the yolk.
