Response of broiler chicks to supplementation of a commercial growth promoter-cum-immunomodulator

A study was conducted to investigate the effect of graded supplementation levels of Livelong (a commercial growth promoter and immunomodulator) on the performance, specific serum biochemistry, haematology, histology of broiler chicks. Supplemental Livelong tended to significantly increase (P>0.05) voluntary feed intake, improve weight gain and efficiency of feed conversion. Broiler chicks fed the control diet recorded the lowest values for these criteria. Mortality was also highest for birds in the control group. Serum biochemical indices and haematology were improved with various levels of supplementation with Livelong. Nutrient retention values for broiler chicks supplemented with Livelong were significantly higher (P>0.05) than the control group. Liver histology was not affected by supplementation levels of Livelong studied. Broiler chicks supplemented with Livelong at 40 ml/L drinking water recorded the highest overall performance.
