One hundred and sixty-five one-day old Cobb broiler chicks were allocated into 3 groups to investigate the effect of dietary 0.1% β-hydroxy-β-methylbutyrate calcium (HMB) and 0.1% creatine on some blood parameters, pro-inflammatory cytokines and growth performance parameters in terms of total feed intake (TFI), total body weight gain (TBWG), total body weight and feed conversion ratio (FCR) during certain time intervals (21st day and 42nd day) versus control group (0 treatment). Some biochemical changes were recorded at the 42nd day among creatine supplemented group in the form of significantly high results of both triglycerides and T3 in group 3 (creatine) than that of the control group on the same day at P value> 0.05. HMB supplemented group showed significantly lower results of ALT (mean) than that of control group at (P value> 0.05) on the 21st day which became insignificant at the 42nd day. Dietary 0.1% HMB-Ca recorded better growth performance parameters in terms of TFI (4.527), TBWG (2.515), TBW (2.555) and TFCR (1.8) if compared to creatine supplemented group of (4.664, 2.508, 2.549 and 1.86) respectively and the control group of TFI equaled to 4.7432, TBWG equaled to 2.156, TBW equaled to 2.1987 and TFCR equaled to 2.2 at the end of the experiment. HMB and creatine supplementations had no effect on other blood parameters, viz. AST, urea, creatinine, total protein, FFA, T4, T3/T4 ratio, TSH, uric acid, cholesterol, HDL and LDL, and pro-inflammatory cytokines namely IL-6, IL-2 and TNF-α. |
