Effect of NanoBioticTM probiotic product on calf growth

The studies show that biologically active feed supplements as probiotics and prebiotics may significantly influence animal performance. This paper discusses the effect of yeast probiotic NanoBioticTM on growth performance of Red Pied calves. The experiment was conducted at the State Unitary Enterprise of Republic of Mordovia Lukhovskoye, the department ‘Goryaynovka in the Oktyabrskiy District. Four groups were formed: two trial groups (Trial Group 1 - calves at the age of 1 month, Trial Group 2 - calves at the age of 3 months) and two control groups (without adding any probiotic). Each group consisted of five comparable animals (the same housing conditions, feeding, age and sex). All animals were apparently healthy, with no signs of respiratory or digestive diseases. The calves of the trial groups were daily fed with milk the yeast probiotic NanoBioticTM at a dose of 2 g day for 30 days. At the beginning and at the end of the experiment individual weighing and clinical evaluation of all animals was made. The farm was satisfactory in terms of infectious and invasive diseases, and preventive measures were taken according to the plan of anti-epizootic measures. The study showed that the use of the yeast probiotic NanoBioticTM had a positive effect on the dynamics of body weight of calves both at 2 and 4 months of age. The application of NanoBioticTM contributed to increased weight gains of calves. Statistically significant results obtained in both age groups indicated the effectiveness of the probiotic product. Higher variability in the control groups emphasizes the effectiveness of using this product to promote the growth of young Red Pied calves.
