The purpose of the study was to assess the impact of varying levels of shrimp meal incorporation on the growth performance, nutrient digestibility, carcass traits and immunological responses of broiler chickens. Three groups of 56 chicks each were randomly selected from a total of 168 day-old mixed-sex broiler chicks and divided into seven replicates of eight chicks. There were three experimental groups: SM1 (2.5 percent shrimp meal), SM2 (five percent shrimp meal), and a control group that was given a diet devoid of shrimp meal. Weight gain, intake of feed, and feed conversion ratio were measured on days 0, 7, 14, 21, 28, and 35. At the completion of the trial, carcass characteristics, gut morphology, and antibody titre were assessed. The study found that in SM2 group, final body weights and average daily gain were significantly higher compared to control group and FCR showed better in SM2 group compare to SM1 and control groups. SM2 showed significantly higher DM digestibility compared to SM1 and control. There were no significant effects on carcass traits.The height of duodenal villi (VH), crypt depth (CD), and the ratio of villi height to crypt depth (VH/CD) were not significantly different from each other. The jejunal VH in the SM2 group was significantly higher than that of the control groups (P<0.05). The ileum’s VH/CD ratio was significantly higher (P<0.05) in the SM2 and SM1 groups in compare to control group. The results of the study show that shrimp meal can be included at the rate of 5% in a broiler diet without compromising performance.
