Peculiarities of the metabolism in broiler chickens under the introduction of multienzyme complex “Rovabio” in the diet

Abstract

The article presents data on studying effects of the enzyme preparation “Rovabio” in rye-containing diets for broilers of the cross “Smena-7” at the age of 14 to 42 days. It was revealed that the inclusion of the enzyme preparation “Rovabio” in the dose of 50 g/t in the combination with trace elements CoCO3 (0.57 mg/kg of feed), Cr2(SO4)3*6H2O (0.38 mg/kg of feed) with the replacement of 15% of wheat to 15% of rye into the diet demonstrated a positive impact of the used dosages of the trace elements on digestibility of organic matter (6.49%), crude protein (4.59%), the protein synthesis and stimulated hematopoiesis in birds. The multienzyme complex increases the integrity of chickens to 96.7% and profitability of poultry meat production by 2.0% due to endo-1.4-ß-xylanase and endo-1.3(4)-ß-glucanase.
