The current study was conducted to investigate the effect of dietary tributyrin (TB) administration on intestinal and growth performances in Arbor Acres (AA) broilers under an isocaloric feeding regime. A total 540 day-old healthy AA were randomly assigned five treatments with 12 replicates (pens) per treatment nine birds pen for 42 days. basal diet (control) TB at doses 0.23 g/kg (TB1), 0.46 (TB2), 0.92 (TB3), 1.84 (TB4). Particularly, achieve cost-saving experimental diets, soybean oil replaced by product (Eucalorie ® ) equivalent metabolic energy contents, formulas rebalanced zeolite get sum all feed ingredients 100%. On days 21 42, after weighing, (one bird replicate) whose body weight close replicate average euthanized morphology, bacterial population, short-chain fatty acid contents. results revealed that increased daily gain, gain/feed ratio, European broiler index ( P < 0.05) improved morphology as indicated higher villus height ratios height/crypt depth broilers. incremental levels ileal Lactobacillus content = cecal Bacillus 0.02), respectively. Moreover, also contents most selected acids digesta 0.05). Collectively, quadratically performance, beneficial regime, indicating better profit return potential practical poultry operation.
