DOI : 10.9775/kvfd.2017.18629 This study was conducted to investigate the effects of physical form of diet and dietary inclusion of enzyme and probiotic on growth performance, mucin2 gene expression, morphology of small intestine and intestinal lactobacillus population of broiler chicks fed with triticale-based diets. Six hundred forty 1-d-old broiler chicks were arranged in 8 treatments with 4 replicates (n=20 chicks). This study was done based on a randomized block completely design in a 2×2×2 factorial arrangement with two levels of feed form (pellet and mash), two levels of probiotic (0 and 0.03% diet) and two levels of enzyme (0 and 0.05% diet). Birds fed with pelleted diet had higher weight gain at starter and grower (P<0.001) and also lower feed conversion ratio at starter (P<0.001) and grower periods (P<0.01) than those fed the mash diet. Birds fed with pelleted diets containing enzyme and probiotic consumed the most feed intake at starter period. Mucin2 gene expression was significantly higher in birds fed the pelleted diets containing enzyme or/and probiotic and mash diets containing probiotic than those fed other diets (P<0.01). Intestinal morphology and intestinal lactobacillus population were not influenced by experimental treatments (P>0.05) Thus, physical form of diet plays important role in improving performance and gene expression in birds fed with triticale-based diets.
