This study evaluated effect of prebiotics (fructo-oligosaccharides) and acidifiers as dietary supplementation. Experimental trial involved 120 one-day-old chicks fed different dietary treatments for the duration of 42-days. The birds were randomly divided into four groups (C, T1, T2, T3; 30 birds each). Group C (control) received standard broiler mash, T1 received mash with prebiotics (0.5% for 0-3 weeks, 0.25% for 4-6 weeks), T2 received acidifiers at same supplementation levels and T3 received a 1: 1 combination of prebiotics and acidifiers at same levels. There was improvement (P<0.01) in carcass traits (dressing percentage, eviscerated weight and giblet yield) with T3 group outperforming others. Morphometric analysis showed increased villus height and width along with reduced crypt depth in T3 group indicating improved intestinal health. Improvements in dry matter metabolizability and nitrogen balance were also higher (P<0.05) in T3 group. Mortality rates were lower in supplemented groups. Furthermore, economic analysis highlighted higher net profit in T3 group, emphasizing cost-effectiveness of combined supplementation.
