Резюме: The purpose of this work is to determine the impact of the polyprobiotic on the growth and physiological condition of broiler chickens. Experiments were carried out with the broiler chickens of 1 to 41 days age. The research was carried out at the X poultry farm in Lithuania, having formed two parallel groups of chickens. Both groups of birds were fed and kept under the same conditions. The only difference was that polyprobiotic preparation had been mixed into the water intended for the experimental group of broiler chickens. During the control slaughter the carcass output, the output of chest, legs and other
muscles of the carcass were assessed. The internal and digestive organs were evaluated during the control slaughter. Muscles of chest and legs were taken for the tests of meat quality. The chemical composition and physical and chemical properties of the muscles were assessed according to the commonly
accepted methods. The results obtained of the experiments showed that the polyprobiotic preparation activates the growth rate of boiler chickens, has positive effect on the microflora of the digestive tract and enhances the immune system. The daily gain of the broiler chickens who had received the polyprobiotic was 6.02 percent, pre-slaughter weight was 13.56 percent, the carcass weight was 14.69 percent, the carcass output was 0.75 percent higher in comparison with the chickens who had not received the preparation.
