Effect of influence of probiotic on the intestinal morphology of Japanese quail
Keywords:Additive, Birds, Duodenum, Morphometry
AbstractThe present study was to evaluate the influence of supplementation of probiotics (Bacillus subtilis (3x108 UFC/g), Aspergillus oryzae (4x106 UFC/g) and Saccharomyces cerevisiae (2x108 UFC/g) on the intestinal morphology of Japanese quail. 400 chicks were used in place until 35 days of age, in a completely randomized design with 2 treatments: control and probiotic, 3 replicates/treatment. At 07, 21, 35 days old were collected fragments of the duodenum of birds to obtain the following parameters height of villi, depth of crypts, number of goblet cells; relationship villus/crypt. The probiotic in addition to the diet resulted in parameter crypt depth of the interaction effect (probiotic / day) at 35 days of age, showing lower value. For height of villi and number of goblet cells no effect of the additive, only the linear effect (time). In the ratio villus/crypt significance is not obtained for the treatments tested only quadratic effect due to time.
