Abstract
The study examined the growth and development indicators of broiler chickens, the digestibility of feed components, the morpho-biochemical parameters of the blood, and the metabolism of elements in the body under the influence of UFC isotopes. The control group received OR, group I — OR + UFC Fe isotope (17 mg/kg of feed), group II — OR + UFC Cu isotope (1.7 mg/kg of feed). A change in the dynamics of live weight gain was noted compared to the control, most pronounced in the first experimental group (by 2.1–6.0%). Digestibility of organic matter and crude fat was higher than the control in the first and second experimental groups, digestibility of crude protein was higher than the control by 9.55–16.7% in all experimental groups.
In the blood of birds from experimental groups I and II, an increase in the number of lymphocytes was observed, in group I — an increase in hemoglobin and its decrease in group II. Biochemical parameters of the bird’s blood serum (AST, creatinine, total bilirubin) indicate an increase in metabolic processes in groups I and II. In groups I and II, a tendency towards a decrease in the content of toxic elements in the bird’s body and an increase in essential elements was noted. In group III, the content of Zn, Cr, Al and Ni in the bird’s body increased. In experimental group I, a decrease in endogenous losses of Fe and Cu was observed. For experimental group II, an increase in endogenous losses was characteristic compared to the control.
