Performance of broiler chicken supplemented with critical amino acids and multi-enzyme on low protein and energy diet

Abstract

Three hundred broiler chicks were allotted to five dietary treatments of three replications and 20 birds in each replication. The control (T0) were standard diet, T1 (5% low CP and energy than standard with balancing of lysine and methionine), T2 (T1 + Multienzyme), T3 (10% low CP and energy than standard with balancing of lysine and methionine), T4 (T3 + Multienzyme). The body weight gain, feed consumption of feed conversion ratio revealed non-significant differences among the groups. The nitrogen retention was significantly more on low protein, low energy diet supplemented with critical amino acids and multi enzymes, however DM metabolizability did not vary significantly. Net profit (Rs/kg) was more in T2 group, where 5 percent low CP and ME diet was supplemented with multi enzymes. It was concluded that 5 percent reduction in energy protein diet supplemented with multienzyme could be economical for broiler production.
