<div>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.&nbsp; 
 
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.&nbsp; 
 
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&lt;0.05) BW, BWG and significantly better (P&lt;0.05) FCR. HA titre was significantly higher (P&lt;0.05) in T3. Per cent breast weight was significantly higher (P&lt;0.05) in T3. Percent crude protein level in breast muscle of turkey poults was significantly higher (P&lt;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.&nbsp;</div>

Effect of Dietary Supplementation of L-Valine on Growth, Immunocompetence Traits, Carcass Quality and Meat Composition of Turkey Poults

<div>Background: Inorganic iron compounds have a positive effect on the health and growth of the broiler chickens. However, limited work has been done in Turkeys. Thus a study was conducted to assess the effect of dietary supplementation of ferrous sulphate on the growth, immunocompetence traits, carcass quality and meat composition of Turkey poults.&nbsp; 
 
Methods: Day old turkey poults (n=96) were distributed into four treatment groups (T1, T2, T3 and T4) having 3 replicates of 8 birds each. The poults in T1 were fed (control) basal diet, while for birds in T2, T3 and T4, FeSO4 was supplemented @ 80, 120 and 160 mg/kg of feed, respectively.&nbsp; 
 
Result: Weekly body weight gain was significantly higher in T4 than T1 and T2 birds at 6th (P&lt;0.01) and 7th week (P&lt;0.05). Phase wise body weight gain was also significantly higher (P&lt;0.05) in T4 than T1 and T2 during 4 to 8 weeks and 0 to 8 weeks (P&lt;0.01). Weekly feed conversion ratio of T4 group was significantly better (P&lt;0.01) at 6th week and 7th week than T1 and T2 group birds. The birds fed with T4 had significantly (P&lt;0.05) higher foot web index compared to T1 and T2 group birds. Iron supplemented groups had significantly (P&lt;0.01) higher dressing per cent. T4 had significantly (P&lt;0.05) higher deposition of iron in thigh muscle. Thus, dietary supplementation of FeSO4 @ 160 mg/kg resulted in better growth performance, immunity, significantly higher dressing per cent and significantly higher deposition of iron in thigh meat cuts.</div>
