Online published on 1 November, 2023. Abstract Background Valine is an important amino acid and its deficiency may result in reduced growth and immunity. However, studies in turkeys are limited. Hence a study was conducted to assess the effect of supplemental L-valine (L-val) on growth performance, immunocompetence traits, carcass quality and meat composition of turkey poults. Methods Day old turkey poults (n=96) were distributed into four dietary treatment groups: T1-basal diet, T2-T1+0.04% L-val, T3- T1+0.08% L-val, T4- T1+0.12% L-val, having three replicates of 8 birds each. Result No significance difference observed in average weekly body weight (BW), body weight gain (BWG) and feed conversion ratio (FCR) of birds throughout experimental period except at 7th week where T2 and T3 poults had a significantly higher (P<0.05) BW, BWG and significantly better (P<0.05) FCR. HA titre was significantly higher (P<0.05) in T3-. Per cent breast weight was significantly higher (P<0.05) in T3-. Percent crude protein level in breast muscle of turkey poults was significantly higher (P<0.05) in T3-. Thus, supplementation of L-val @ 0.08% in turkey poults resulted in significantly better humoral immune response, higher percent breast yield and higher percent crude protein in breast meat.
