Abstract—The objectives of the current study were to evaluate the performance responses, guts healthiness, and carcass characteristics of broiler chickens fed on formulated diets included dried coriander, turmeric and thyme. Unsexed commercially available chicks were enrolled into five experimental treatments each of eighty birds with four replicates per treatment. The birds were housed in deep litter clean pens. The experimental groups were as follow: Control; coriander; thyme; turmeric, and mixed. Two formulated diets (starter & finisher) to which all the dietary additives were added in a dried powdered form and at the level of 0.75% expect for the mixed group as each additive was used at level 0.25%. Performance parameters including weekly body development, body weights gain, feed intake, and feed conversion ratio were recorded during the 35-d experimental period. Also, representative samples from each replicate were gathered for the detection of carcass traits, consumer acceptability, and the gut morphometric changes. The data revealed that coriander, and turmeric significantly (p<0.05) increased the villus heights and crypt depths as compared to control which is concomitant with the improvement of performance results when incorporated solely in broilers diet at 0.75% level , but consumer acceptability was lowered specifically for the turmeric –fed group.
Keywords— Broiler performance, Coriander, Gut, Thyme, Turmeric.
