The effect of bacterial inoculant on the histology of japanese quail jejunum under protein-deficient diets

After discovery of the harmful effects of antibiotics on health of poultry flocks and humans efforts in using alternative materials increased. Some of the most appropriate materials known and used are prebiotics, probiotics and synbiotics. The purpose of this study was to investigate the effect of probiotics, prebiotics and synbiotics in Histomorphometry parameters of jejunum, as the main location of food absorption, in the Japanese quail. The effect of probiotics, prebiotics and synbiotics in jejunum was studied using a 2×4 factorial experiment with two levels of protein (recommended and 10% less than requirements) and four treatments of additives (without additives, probiotic Gallipro, prebiotic Technomos and a mixture of them in a completely randomized design with eight treatments and four replicates and 25 birds per replicate). Results indicated a significant increase in villus height:crypt depth ratio in groups nourished with protein deficiency (P
