| dc.description.abstract | An experiment was conducted to study the effect of feeding varying levels of subabul (Leucaena leucocephala) leaf meal on on growth, nutrient utilization, blood biochemical profile, carcass characteristics and to evaluate economics of feeding in commercial broiler chicken. One hundred eighty (N=180) commercial broiler chicks (Vencobb 400) were randomly distributed into 4 groups (T0, T1, T2 and T3) on live weight basis comprising of 45 chicks in each group with three replicates of 15 chicks in each. The control group (T0) was fed with a standard pre starter, starter and finisher broiler ration as per ICAR (2013) specifications. The chicks belonging to group T1 was fed with standard ration along with 5% inclusion of subabul leaf meal. Birds belonging to group T2 and T3 were fed rations along with inclusion of 10% and 15% subabul leaf meal, respectively in all pre-starter, starter and finisher phases. At the end of pre-starter, starter and finisher phases blood samples were collected and analysed for blood biochemical parameters. Three birds from each group were slaughtered to study the carcass characteristics and chemical composition of meat. The economics of feeding and broiler production were evaluated. Highly significant (p<0.001) differences were observed in weekly change in body weight, weekly and total gain in body weight, weekly and total feed intake, feed conversion ratio, digestibility of nutrients, retention of nitrogen. Dietary inclusion of subabul leaf meal at 5% level had no adverse effect on growth performance, digestibility of nutrients and carcass characteristics. Non-significant (p>0.05) differences were observed in retention of calcium and phosphorus, dressing percentage, yield of prime cuts, serum total protein, total cholesterol and total triglyceride level. Cost of production when calculated revealed that inclusion of subabul leaf meal at 5% level in broiler rations was more profitable than feeding diets without any inclusion or beyond 5% level of inclusion i.e. 10% and 15%. The highest gross profit was observed in treatment group T1, receiving 5% inclusion of subabul leaf meal. Hence, the study indicated that broilers could be reared more economically and profitably on broiler rations with 5% level of subabul leaf meal inclusion. | |
