The trial involved 480 Hubbard Classic broiler chicks which were from either mannanoligosaccharide (MOS) fed breeder flock (Bio-Mos, Alltech Inc. USA at level of 1 kg/t) or control fed breeder flock (without MOS). Three groups with four replicates per treatment were formed: control fed breeders/control fed broilers (C/C); MOS fed breeders/control fed broilers (BM/C) and MOS fed breeders/MOS fed broilers (BM/BM). All chicks were fed the same basal diet, except for the inclusion of Bio-Mos (1, 0.75 and 0.5 kg/t in the starter, grower and finisher diet, respectively). The results showed a significant improvement (p<0.05) in the body weight gain with the addition of Bio-Mos in broiler feed. Feed conversion ratio was improved by 0.03 points, but the difference was not significant (P>0.05). The gut morphology examination showed that chick origin (chicks that originated from Bio-Mos fed breeders or control fed breeders) did not influence the morphological parameters of the jejunum in the broiler chickens, but addition of Bio-Mos directly to the broiler feed had a significant influence on the gut morphology and played an important role in processes of digestion and absorption, leading to improved performance.
