Fecal microbiology in puppies supplemented with probiotics receiving different diets

The aim of this research is to evaluate supplementation effects of two probiotics to Beagle puppies receiving two diets (high and low quality) over microbiote and faecal pH. They were used 18 Beagle puppies shared in three treatments : 1) treatment 1: control (food); 2) treatment 2: food with probiotic 1 (Bifidobacterium); 3) treatment 3: food with probiotic 2 (Lactobacillus). Research was shared in two levels, each charactherized to different quality foods changing. It was used food fats how stress agent. Analysis made were water and foods microbiology and faecal microbiology (E. coli, Lactobacillus, Bifidobacterium and Clostridium sp.). It was verified significative results (P<0,05) in faecal microbiote with probiotics useful. It was verified differences in pH analysis (P<0,05) with probiotics useful too. It was concluded that probiotic 1 present more efectivity in gastrintestinal tract (beneffic) for Beagle puppies.
