<div style="text-align: justify;">The effect of a prebiotic mannan oligosaccharides (Actigen&trade;) supplementation for 35 days was analyzed on growth, carcass traits and blood physiology of broilers. A total of 360-day-old broilers distributed under completely randomized design into four treatment groups with 24 replicates of 15 birds each was fed with Actigen&trade; supplemented diets @ 0.2, 0.4 and 0.6 g/Kg and a control diet. Data for growth performance were collected weekly while slaughtering data at 35th day. Results showed that the birds fed with Actigen&trade; added diet @ 0.6 g/Kg exhibited improved livability% (98.88&plusmn;1.11), feed intake (3391.68&plusmn;38.70 g), body weight (2157.66&plusmn;31.52 g), weight gain (2111.49&plusmn;30.89 g), FCR (1.57&plusmn;0.03), dressing% (72.28&plusmn;0.40), breast yield% (29.58&plusmn;0.05), thigh yield% (31.61&plusmn;0.30) and blood biochemical parameters. Superior (P&pound;0.05) antibody response against ND and IB were recorded in birds exposed to Actigen&trade; supplemented diet @ 0.6 g/Kg. &nbsp;It was concluded that Actigen&trade; supplementation @ 0.6 g/Kg corroborated to improve growth, carcass traits, blood biochemistry and antibody response in broilers.</div>
