摘要

The present study was investigated effect of CLM on thyroid hormone profile, immunity, expression of IL6 & HSP70 gene and antioxidant status of broiler. 240 day-old chicks were distributed into 6 groups having 8 birds in each replicate. The diet was formulated as per BIS (2007) standards for T1, while T2, T3, T4, T5 and T6 were given diets substituted with CLM @ 50, 75, 100, 125, and 150 g/kg, respectively for 42 days. The weekly feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) in the experimental group of birds fed CLM was comparable to that of the control group. Mortality of 3.75% was recorded. The weight of the spleen, thymus and humoral immune response was significantly (P < 0.05) higher in T6 group. On 21st day, serum IL6 levels was significantly (P < 0.05) lower in T4, T5, and T6. On 42nd day, it was significantly (P < 0.05) lower in T6. Relative expression of the HSP70 gene in liver tissue was significantly (P < 0.05) down regulated in T6. The serum SOD and catalase levels were significantly (P < 0.05) higher in T4, T5, and T6. Serum FRAP and DPPH values were significantly (P < 0.05) higher in T5 and T6. The thyroid hormone profile, weight of bursa, cell-mediated immune response and serum GPx levels had remained comparable. Hence, it is concluded that CLM inclusion in a diet up to 15% improves immunity and antioxidant and alleviates heat stress in chickens.
