Effects of prebiotics on intestinal histo-morphometry and gut microflora status of broiler chickens (original) (raw)

2018, Indian Journal of Animal Research

A feeding trial was conducted to assess the effect of prebiotics on intestinal histo-morphometry and gut health status of broiler chickens. A total number of 240 day-old broiler chicks were randomly assigned to six dietary treatment groups having five replicates each with eight birds per replicate for six weeks. A basal corn-soybean diet was formulated that served as control (T1). The rest five test dietary treatments were prepared by adding antibiotic (bacitracin methylene di-salicylate-BMD at 0.002% of diet (T2), prebiotics i.e., mannan oligosaccharides (MOS) at 0.1% or 0.2% (T3 and T4) and fructo oligosaccharides (FOS) at 0.1% or 0.2% (T5, T6 respectively) with basal diet. Total anaerobes counts were significantly (P LESS THAN 0.05) reduced at 21 and 42 d at ileum in T2, T3 and T4 groups whereas, coliforms count were reduced (P LESS THAN 0.05) in T2 and T3 groups. However, lactic acid bacteria (LAB) count were significantly (P Less than 0.05) increased in T3 and T4 groups but lac...
