| dc.description.abstract | The present research work was carried out in the Department of Animal Husbandry and Dairying, Institute of Agricultural Sciences, BHU, Varanasi after approval of the Central Animal Ethical Committee of the University. In this experiment three hundred and sixty unsexed Cobb-400 chicks of 7 days old were weighed and randomly distributed to 36 floor pens (with 10 birds in each pen) following completely randomized design. The six dietary treatments were M0L0 (control; basal diet without MOS (mannan oligosaccharide) and LA (lactic acid) supplementation, M0.5L0 (basal diet with 0.5% MOS), M0.5L1 (basal diet with 0.5% MOS and 1% LA), M1L0 (basal diet with 1% MOS), M1L1, (basal diet with 1% MOS and 1% LA), and M1L2 (basal diet with 1% MOS and 2% LA). Highest improvement in retention of Ca and P was observed in M0.5L1 group whereas, Fe, Zn and Cu was recorded in LA supplemented groups M1L1 and M1L2. Cost of production for per kg live weight and dressed weight was found lowest in lower levels of MOS and LA supplemented groups; M0.5L0 and M0.5L1 whereas highest in higher levels of MOS and LA supplemented group M1L2. Carcass characteristics, nutritional composition, color (L*a*b*), textural, sensory scores and fatty acid profile remained similar among the groups. Gut health in terms of pH of different intestinal segments, microbial counts of the digesta in these segments and length of jejunum, ileum and caecum improved on MOS and/or LA supplementation. While, GIT weight and diameter of different intestinal segments remained similar. Improvement in immunity as indicated in higher bursal and thymus weight were also recorded in treated group. Lipid profiles and serum lipid oxidative enzymes were improved with treated group. Thus supplementation of diet either with 0.5% MOS or 0.5% MOS and 1% LA in the poultry ration was found better in terms of growth, cost of production and health performance. | en_US |
