This research investigated the effect of adding tomato powder to fish oil-containing diet on performance and egg quality of native laying hens. One hundred twenty native laying hens with initial hen day production of 60.83±8.48% (coefficient of variation 8.48%) were randomly distributed in a completely randomized design experiment with 4 treatments and 6 replications (each replications consisted of 5 birds). Treatments used were PO: basal feed + 2.5% palm oil (control); FO: basal feed + 2.5% fish oil; FO-0.5TP: basal feed + 2.5% fish oil + 0.5% tomato powder; FO-1.0TP: basal feed + 2.5% fish oil + 1.0% tomato powder. The treatments did not affect (P>0.05) feed intake, egg weight, and egg mass. Fish oil-containing diet (FO) showed lower (P<0.05) hen day production and feed conversion ratio compared to the other diets, However, addition of tomato powder in fish oil-containing diet, had no significant differences in hen day production and feed conversion ratio when compared to control group. There were no significant effects (P>0.05) of treatments on egg shape index, shell weight, shell thickness, shell surface area, albumen weight, Haugh Unit, yolk weight, and yolk color. The conclusion of this experiment is that adding tomato powder could ameliorate negative effect of fish oil-containing diet on hen day production and feed conversion ratio of native laying hens. © 2016, Fundacion CIPAV.
