The study was conducted to evaluate the growth performance, immune organs weight and hematological changes in broiler chickens on supplementation of Mannan-oligosaccharide (MOS) and Protexin. 240 day-old broiler chicks were supplied with control diets (A), MOS (B), Protexin (C) and symbiotic (MOS+Protexin-D). The MOS and probiotic was supplied 1000 and 100 g/ton in starter and 500 and 75 g/ton in finisher diet, respectively. The growth performance viz., body weight, body weight gain and feed conversion ratio were obtained weekly up to the 6th week of age whereas the hematological and organ weight was obtained on 4th and 6th week of age. The average body weights and weight gain from the 3rd to 6th week of age were improved (P<0.01) in same trend among groups B, C and D as compared to A (control). The average feed intake (FI) and feed conversion ratio (FCR; P<0.01) at 6 weeks was significantly better in MOS, protexin and symbiotic fed groups than control. Bursa had significantly (P<0.05) higher weight in symbiotic group. No differences were observed in blood parameters and haemato-biochemical studies. It concluded the MOS and protexin supplementation may improve the growth with improved FCR and immune status of the broiler chickens with optimum economy.
