Abstract
An experiment was conducted to study the influence dietary supplemental of Arg on productive performance and physiological traits in chickens during the growing period (one day-12 weeks of age). Four hundred and twenty unsexed–one day old chicks of Silver Montazah (SM) chicks were randomly distributed into four groups (each of 1o5 chicks) with three replicates (each of 35 chicks). The 1st group (T1) was fed the basal diet containing (1.14 % Arg) and served as control group. While the 2nd, 3rd and 4th groups were given the basal diet with 0.20, 0.25 and 0.30 % Arg, respectively. The obtained data revealed the following results: live body weight (LBW), body weight gain (BWG), Keel (KL) and shank lengths (SL) were enhanced with increased dietary Arg at 12 wks of age, likewise, feed consumption (FC) values were significantly (P≤0.05) decreased in chicks fed 0.30% Arg (T4) supplemental diet compared with the control group. Also, chicks fed diet supplemented with 0.20, 0.25 and 0.30% Arg (T2, T3 and T4) recorded better feed conversion ratio (FCR) than control group during the whole period. Adding Arg to the diet of chicks by 0.25 and 0.30% levels resulted in a significant increase in total erythrocytes count (RBC), hemoglobin concentration (Hb), total leucocytes count (WBC) and lymphocytes ratio (L %) and a significant decrease in heterophils (H %), monocytes (M %), eosinophils (E) and H/L ratio value at 12 wks of age as compared with T2 and control groups. The high level (0.30%) Arg (T4) significantly (P≤0.05) increased the nitric oxide (NO) and growth hormone (GH) and decreased significantly IGF-1 hormones than the basal diet (control group). The results of the present study indicated that arginine supplementation during the growing period caused promote the growth performance and had beneficial effects on some physiological responses of Silver Montazah chicks.
