Formation of element status at chickens when using enzyme, probiotic and antibiotic agents in food

Abstract

The paper considers the biological effect of probiotic, enzyme and antibiotic agents on metabolism, efficiency and the element status of chickens. Joint inclusion of soybean-bifidum (0.7 ml/kg of feed), Tselloviridin G20x and Biovit-80 resulted in the increase of the egg weight by 9.8 and 9.0%, respectively in comparison with other groups. The group receiving Sporobacterin (10 ml/kg of feed) with feed was characterized by high fat availability (68%). The greatest conversion of feed gross energy was observed in groups in case of joint inclusion of Tselloviridin with probiotic and antibiotic agents (2.8 and 3.0%) and crude protein (6.2 and 7.0%). The spectral microelement analysis showed that the additional inclusion of biologically active agents caused their redistribution towards the increase of the need for main micronutrients for metabolism. All groups were characterized by a reliable increase of essential and conditional-essential elements such as Ca, K, Mg, Na, P, Cr, Cu, Fe, I, With, Mn, Se, Zn against the background of decrease such toxic elements as As, Al, Ag, Sr, Pb, Cd. The received results confirm the modeling role of probiotics, enzymes and antibiotics in the exchange of micro- and macronutrients.
