Efficiency of application of the yeast probiotic in complex with enzyme the duck productivity

We conducted a scientific and economic experiment on ducklings of 100 heads in each group of cross "cherry valley" in the conditions of LLC "Farm" Ramaevskoe " Laishevsky district of the Republic of Tatarstan. The ducks of the control group received a complete feed without additives. Broilers of the first experimental group in addition to the main diet included feed additive "Actisaf11 in a dose of 0.3 g per 1 kg of feed, the second experimental group-polyfermentny drug "Universal" in the recommended dose of 0.1 g per 1 kg of feed. Birds of the third experimental group received a complex preparation based on the enzyme "universal" and probiotic "Actisaf11 at a dose of 0.4 g/kg of feed. It was found that the best results by the end of the experiment were in ducklings of the third experimental group with the inclusion of an enzyme-probiotic complex in the diet. The live weight of broilers in this group by the end of the experiment reached 3690g, which is 360 g or 10.8 % significantly more than the birds of the control group, the economic efficiency was 56.3 rubles, including the calculation of 1 ruble of additional costs 2.03 rubles.
