Supplementation of multiple enzymes and organic trace mineral supplementation to the diets containing sub-optimal energy on performance and carcass traits of commercial broilers

An experiment was conducted to study the performance and carcass parameters of broilers fed with sub-optimal metabolizable energy (100 and 200 kcal/kg less ME) diets supplemented with multiple Enzyme (400g/ton feed) and organic trace mineral supplement. A total of 300-day-old commercial broiler chickens were distributed in a completely randomized design into 6 treatments with 10 replicates of 5 chicks each. Treatments comprised of T₁- basal diet (BD) without enzyme (EZ) or organic mineral (OM) supplementation; T₂- 100 kcal/ kg less metabolizable energy (ME) without EZ and OM (BD 1); T₃- 100 kcal/kg less ME with EN (BD1+EZ); T₄- 200 kcal/kg less ME without EN and OM (BD 2); T₅- 200 kcal/kg less ME with EZ (BD2+EZ); T₆- BD with organomin supplementation (BD+OM).The results revealed significantly (P<0.05) improved body weight in all dietary treatments groups except BD2 (200 kcal/kg less ME without EN and OM) at 6 weeks of age. Significantly (P<0.05) higher feed intake was observed in BD1+EZ, BD+OM and BD1 compared to control and other treatment groups. No significant difference was recorded in feed efficiency among different dietary treatments. All dietary treatments failed to exert any significant (P>0.05) influence on various carcass parameters except abdominal fat which was significantly high in BD+OM group compared to other treatments.
