Abstract: The experiment was conducted to investigate the effect of dietary inclusion of mulberry (Morus alba) leaf meal with or without multienzyme on growth performance, nutrient metabolizibility, carcass traits, haematobiochemical parameter and economics of broiler production. The 288 broiler chicks were equally assigned to six groups, having four replications with 12 birds per replication. The dietary treatments containing T0 (negative control), T1 (5% MLM), T2 (10% MLM), T3 (positive control), T4 (5% MLM with multienzyme) and T5 (10% MLM with multienzyme). At the end of experiment, broilers fed diet with inclusion of 5% and 10% level of mulberry leaf meal with and without multienzyme had showed significantly higher body weight compared to control (T0). Body weight gain was (p<0.05) significantly higher during 2nd and 3rd week in broilers fed diets with 5% and 10% MLM with and without multienzyme compared to negative and positive control. But during 1st, 4th, 5th and 6th week, body weight gain was not significant among the treatment groups. Cumulative feed intake (g/bird/week) among different treatments during 1st, 3rd, 4th, 6th week did not differ significantly. However, during 2nd week and 5th week, cumulative feed intake differed significantly among the treatments groups. Improved FCR was observed in broilers fed diets with inclusion of 5% or 10% MLM supplemented with multienzyme compared to broilers fed diets with inclusion of 5% or 10% MLM only. Further, FCR was significantly better in MLM added group compared to control group. In nutrient metabolizibility studies, dry matter retention, organic matter retention, crude fiber retention, NFE retention did not differ significantly. However, crude protein retention and ether extract retention was higher in broilers fed different levels of MLM supplemented with multienzyme. 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 MLM with and without multienzyme. The average values of dressing percent, eviscerated yield (%), boneless breast meat (g), boneless leg meat (g), giblet (gm) did not differ significantly among the treatments. However, abdominal fat was significantly (P<0.05) less in broilers fed diets containing 5% and 10% MLM with or without multienzyme. The results showed that feeding of 5% and 10% MLM reduced the TBA value of meat in broiler and feeding of 5% MLM with or without multienzymedelayed the lipid oxidation in broiler. Thus, dietary inclusion of MLM with and without multienzyme could improve the shelf life of the chicken. Inclusion of MLM with or without multienzyme did not adversely affect sensory parameters in broiler meat. The average values of hemoglobin, packed cell volume (%) were observed non significant among treatments and within normal physiological range. Serum total protein, serum albumin (g/dl) and albumin: globulin (g/dl) was significantly higher in broilers fed diet with inclusion of different levels of MLM supplemented with multienzyme. Serum globulin (g/dl) did not differ significantly. However, Serum cholesterol showed highly significant (p<0.05) variation among treatment groups. T1 (5% MLM) and T2 (10% MLM) showed lowest serum cholesterol followed by T4 (5% MLM with multienzyme) and T5 (10% MLM with multienzyme) and highest in T3 and T0. During the course of experiment, it was observed that net profit per bird was Rs. 18.09, 31.59, 34.72, 30.53, 34.50 and 39.05 in T0, T1, T2, T3, T4 and T5 respectively. The net profit was observed highest in broilers fed diet added 10% MLM with multienzyme (T5) followed 10% MLM without multienzyme T2, 5% MLM with multienzyme (T4), and 5% MLM without multienzyme (T1) compared to the negative control. In conclusion, mulberry leaf meal up to 10% inclusion level can be added successfully in the diet of broilers without any adverse effect on the performance of broilers. Dietary inclusion of mulberry leaf meal with and without multienzyme improved overall performance, increased shelf life of meat and even decreased serum cholesterol in broilers vis a viz control which resulted into increased the net profit by reduced cost of feed per kg live weight gain.
