Effect of yeast based mannan oligosaccharide (Actigen™) supplementation on growth, carcass characteristics and physiological response in broiler chickens

The effect of a prebiotic mannan oligosaccharides (Actigen (TM)) 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 (TM) 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 (TM) added diet @ 0.6 g/Kg exhibited improved livability% (98.88 +/- 1.11), feed intake (3391.68 +/- 38.70 g), body weight (2157.66 +/- 31.52 g), weight gain (2111.49 +/- 30.89 g), FCR (1.57 +/- 0.03), dressing% (72.28 +/- 0.40), breast yield% (29.58 +/- 0.05), thigh yield% (31.61 +/- 0.30) and blood biochemical parameters. Superior (P <= 0.05) antibody response against ND and IB were recorded in birds exposed to Actigen (TM) supplemented diet @ 0.6 g/Kg. It was concluded that Actigen (TM) supplementation @ 0.6 g/Kg corroborated to improve growth, carcass traits, blood biochemistry and antibody response in broilers.
