Studying the effect of yeast probiotic NanoBioticTM on productivity, clinical and hematological indices of broiler chickens and quails

Abstract

The effect of the probiotic product NanoBiotic^TM on the productivity and health of poultry was studied. We studied the effect of the yeast probiotic product on broiler chickens of Cobb 700 cross and Manchurian quails. The experiment was conducted in the veterinary clinic of the Ogarev Mordovia State University and the Mordovian Republican Veterinary Laboratory. Apparently healthy birds of the same age and sex were selected for the experiment: 10-day-old broiler chickens (hens) and 15-day-old quails (cockerels). The birds were kept in cages with group feeding and watering. Broiler chickens of the trial group were administered NanoBiotic^TM probiotic at a dosage of 0.03 g per individual daily for 30 days. The quails of the trial group were given the probiotic similarly, but for 20 days. The control groups received the standard diet without additives. Individual weighing of the birds was made weekly. Hematological blood tests were done before and after the experiment. The obtained data were processed statistically using Student’s t-criterion in Microsoft Excel. The application of NanoBiotic^TM probiotic did not cause any negative consequences for the health of birds, and did not affect the state of respiratory and digestive organs. The application of probiotic resulted in improvement of growth indices in the trial groups compared to the control groups. More intensive growth and live weight gain were observed. In addition, the probiotic had a beneficial effect on blood composition, contributing to the strengthening of immunity and increasing the number of monocytes, erythrocytes and hemoglobin concentration. At the same time, all hematological indices remained within the average and upper limits of the physiological norms.
