Intestinal microbiocenosis and fodder digestibility in broiler chickens when using probiotics

Abstract. Research objective was to study the intestinal microbiocenosis in broiler chickens. Laboratory test conducted at and Development Center for Agriculture of North-Western Branch Tyumen SB RAS. Methods. Cobb 500 chickens breed used. The main part experiment began age 14 days. By this time, had reached an average body weight 365 grams. control group fed basic diet, consisting total mixed ration fodder pure water. Chickens 1st experimental during stage were with “Vetom 2” probiotic additive drinking water 50 mg / 1 kg poultry weight, whereas 2nd “Lactobifadol” added their rate 0.2 g per weight. results have showed that prior feeding formulations no pathogenic microflora observed droppings Conditionally bacteria, such as Proteus mirabilis, Klebsiella oxytoca, pneumoniae, Staphylococcus aureus present. Bacillis spp. present all samples. After formulations, detected groups. bacteria mirabilis chickens, group, group. Concentrations Bifidobacteria Lactobacteria chickens’ significantly higher than rest Bacillus samples 2”. It also other Scientific novelty. involving aimed researching its effect on digestibility Northern Trans-Urals conditions first time.
