This study was conducted to examine the growth performance, sensory attributes, and expression patterns of the interleukin-10 and interleukin-1β genes in the spleen of chickens subjected to Aframomum chrysanthum seed meal (ACSM) as a replacement for synthetic antibiotic in broiler production. A total of one hundred and forty-four day-old Aboracre strains of broilers were randomly allotted into four dietary treatments. Treatments one (control) had no ACSM in the diet but was given routine antibiotics medication for broilers. Treatments two (T2), three (T3), and four (T4) had ACSM at 1%, 1.5%, and 2% inclusion levels. The experimental diet was fed for 8weeks; Daily feed intake and weekly body weight were collected, panelist were trained for sensory evaluation of meat, while spleen samples were collected after the feeding trial for gene expression analysis. The feed intake data showed no significant changes (P>0.05);likewise the final weight, feed conversion ratio and feed efficiency, while weight gain was significantly different (P<0.05) with values of 1986.74 ± 13.54 (T2) to 2202.59 ± 53.34 (T1). Sensory attributes varied significantly (P<0.05) and improved with increased inclusion of Aframomum chrysanthum seed meal (ACSM). There were also no significant differences (P>0.05) in expression patterns of interleukin 10 (1L-10) and interleukin 1β (1L-1β) in the spleen of chickens fed ACSM. However, the expression of IL-10 increased with increased inclusion of the test ingredients while IL-1β decreased with increased inclusion of the test ingredients. The study concludes that ACSM has the phytochemical potentials of regulating inflammation and immune response in broiler chickens without affecting feed efficiency and also improving sensory attributes of meat.
