Abstract: The present study was planned to study the effect of varying level of dried hedge lucerne leaf meal supplemented with and without multienzyme through feed on the growth performance, nutrient metabolisibility, carcass trait, haematobiochemical parameters and economics of broiler production. 312 broiler chicks were equally divided into six groups of four replicates each having 13 chicks. In various groups different treatment were used viz. Group I (To) negative control (standard broiler diet without HLLM & multienzyme), Group II (T1) 3% HLLM, Group III (T2) 6% HLLM, Group IV (T3) positive control (standard broiler diet without HLLM & with multienzyme), and Group V (T4) 3% HLLM with multienzyme, and Group VI (T5) 6% HLLM with multienzyme. At the end of experiment, it was observed that broilers fed diet containing 6% HLLM supplemented with multienzyme T5 (1913.27 ± 39.85) had significantly higher body weight followed by T4 (1859.65 ± 32.74), T3 (1827.85 ± 61.14), T2 (1795.2 ± 24.75), T1 (1747.6 ± 19.99) and least in control group T0 (1709.9 ± 38.72). Positive control (T3) showed significantly higher body weight than negative control (T0). Statistical analysis revealed that mean values of body weight gain (g) showed no significant variation among different treatment groups. Cumulative feed intake (g/bird/week) among different treatments during 2nd, 4th, 5th, 6th week did not differ significantly. However, during 1st week and 5th week, cumulative feed intake (g/bird/week) differed significantly among the treatments groups. Feed conversion ratios were significantly different (P<0.05) among treatments groups during all 1st, 2nd, 3rd, 4th, 5th, 6th week. In 6th week, T3, T4, and T5 had significantly better FCR, T1 and T2 were intermediate compared to T0. The results of metabolism trial revealed that dry matter, organic matter, ether extract, crude fiber, NFE retention did not differ significantly. Crude protein retention (%) was significantly higher in T3 (64.45 ± 1.59). T1 (61.49 ± 0.46), T4 (62.80 ± 1.11), T5 (60.94 ± 1.17) remained intermediate and T2 (59.93 ± 0.91) and T0 (59.30 ± 0.45) remains comparable. Nitrogen, phosphorus, manganese, Iron, copper, zinc balance did not differ significantly among treatments. However, calcium balance was significantly higher in broilers fed diets having varying levels of HLLM with andwithout multienzyme. The average values of dressing percent, eviscerated yield (%), boneless breast meat (g) and boneless leg meat (g) differed significantly among the treatments. However, broilers fed diets containing 3% and 6% HLLM with or without multienzyme showed significantly (P<0.05) less abdominal fat. The results further revealed that feeding of 3% and 6 % HLLM reduced the TBA value (mg MDA/Kg) of meat in broiler and feeding of 3% and 6 % HLLM with or without multienzyme delay the lipid oxidation in broilers meat. Inclusion of HLLM with or without multienzyme did not adversely affect sensory parameters in broiler. The value of haemoglobin (%), packed cell volume (%), serum total protein (g/dl), serum albumin (g/dl), serum globulin (g/dl), albumin: globulin ratio and serum cholesterol did not differ significantly among the treatment groups. The results of the economic analysis revealed that net profit per bird was Rs. 16.97, 27.15, 26.74, 29.94, 33.88, and 36.11 in T0, T1, T2, T3 , T4 and T5 respectively. Inclusion of different levels of HLLM with or without multienzyme in broilers diet reduced the cost of feed per kg live weight gain and increased the net profit. Further, inclusion of 6% HLLM with multienzyme (T5) had fetched net profit followed by 3% HLLM with multienzyme (T4), 6% HLLM (T2), 3% HLLM (T1), positive control (T3) as compared to negative control (T0). In conclusion, growth performance and feed efficiency could be improved on dietary inclusion of HLLM up to 6% in broilers diet with or without multienzyme particularly during chronic heat stress without having any adverse effect on nutrient metabolisability and haematobiochemical parameters. Carcass traits and shelf life of meat could be improved on dietary inclusion of HLLM up to 6% in broilers diet with or without multienzyme. Further, dietary inclusion of HLLM with and without multienzyme reduced cost of feed per kg live weight gain and increased the net profit by improving overall performance in broilers.
