The effect of multi-strain probiotics as feed additives on performance, immunity, expression of nutrient transporter genes and gut morphometry in broiler chickens.

ABSTRACT:

Objective

This study was conducted to investigate the effects of dietary multi-strain probiotic (MSP) (Bacillus coagulans Unique IS2 + Bacillus subtillis UBBS14 + Saccharomyces boulardii Unique 28) on performance, gut morphology and expression of nutrient transporter related genes in broiler chickens.

Methods

A total of 256 (4×8×8) day-old CARIBRO Vishal commercial broiler chicks of uniform body weight were randomly distributed into four treatments with 8 replicates each and having eight chicks in each replicate. Four dietary treatments were T1 (negative control-basal diet), T2 (positive control-antibiotic bacitracin methylene disalicylate at 20 mg/kg diet), T3 (MSP at 107 colony-forming unit [CFU]/g feed), and T4 (MSP at 108 CFU/g feed).
