Poultry farming using modern technologies requires the employment of veterinary preparation for the prevention of infectious diseases and also feed additives for the improvement of metabolic functions and correction of body resistance.
The article presents the results of clinical trials of feed additives in the form of an ionic solution concentrate of the biologically active nanosilicon "Arsil". The clinical study was performed on healthy ten-day-old broiler chicken, cross "Cobb-500", organized into three groups of 20 heads each: Group I received a feed additive at a dose of 0.5 ml per 1 liter of water, group II – at a dose of 1.0 ml per 1 liter of water and group III was the control group (on a regular diet, without feed additives). The use of the studied feed additive was carried out by watering with water for 30 days. Poultry of all groups were fed with identical feeds in accordance with regulatory requirements taking into account the age of the bird. The clinical condition of the bird was monitored daily, control weightings were performed once a week and blood samples were taken for laboratory tests on days 15 and 35 of the experiment. At the end of the experiment, a diagnostic slaughter of birds of all groups and a complete pathological autopsy with selection of material for histological examination were performed.
Studies have shown that the use of the feed additive "Arsil" contributed to weight gain and average daily gain, improved the feed conversion and the tendency for the growth of the concentration of hemoglobin, hematocrit and erythrocytes in broiler chicken from the experimental groups compared with the control group at the end of fattening. The structure of the internal organs of birds of all studied groups is preserved, macroscopic changes in organs and tissues are not detected. An increase in the coefficients of mass of immune-competent organs in broiler chicken fed the feed additive "Arsil" compared with the control group was found.
