Efficiency of use of the probiotic preparation "Subtilis" for post-weaned piglets

The purpose of the work was to study the efficiency of probiotic "Subtilis" application in liquid form and powdery forms in the technology of piglets rearing during the nursery period. The research was conducted on post-weaned piglets of Pyetren breed. The differences between groups of animals were that the probiotic "Subtilis-G" was added to a diet of animals of the second experimental group, probiotic "Subtilis-C" was added to a diet of animals of the third experimental group, while the animals of the control group were on the standard diet accepted at the enterprise. Scientific, economic and physiological experiences showed that the use of these medicines increased digestibility of the dry substance by the animals of the second experimental group by 1.4%, crude protein by 2.1%, crude fat by 3.8%, crude cellulose by 2.4%, nitrogen free extractable substances by 3% in comparison with the control group. It was revealed that the best productivity indicators were received from the piglets of the second experimental group, the average daily gain was 7.4% more than of the control group. The application of probiotic "Subtilis-C" allowed to increase an average daily weight gain by 5.4% in comparison with the control group at the decrease of forage expense for 1 kg of a live weight gain by 6.9%. The received results showed high efficiency of application of the soporiferous probiotic "Subtilis" both in the liquid and in the powdery forms. However, the application of "Subtilis-G" showed the best result. The received data were confirmed with the production inspection. It was defined that both liquid and powdery forms of probiotic "Subtilis" had equal efficiency. As a result of the use of the above mentioned medicine the production profitability during the nursery period increases by 7.4%.
