PHYSIOLOGICAL AND BIOCHEMICAL PARAMETERS OF BLOOD AND PRODUCTIVITY OF RABBITS AFTER FEEDING NANOTECHNOLOGICAL
Abstract
The effect of selenium citrate on blood parameters and rabbit productivity was studied. The study was conducted in a private rabbit farm on young rabbits of the Hylla breed. The animals were divided into four groups - control and three experimental. Rabbits in the control group consumed standard pelleted feed and water without restrictions, according to current requirements. The first experimental group, in addition to the standard diet with drinking water during the day, received an aqueous solution of nanotechnology selenium citrate in the amount of 50 μg Se/l. Accordingly, the second experimental group consumed selenium citrate at the rate of 100 μg Se/L; the third experimental group received selenium citrate at the rate of 200 μg Se/L. During the experimental period (days 15 and 30 of the study), the safety and growth rate of the rabbits of the control and experimental groups were monitored daily. All the obtained digital data were processed using the STATISTICA computer program using the method of variation statistics.
The analysis of the results obtained indicates a positive effect of selenium citrate feeding on red blood counts, depending on its amount and period of use. A more pronounced biological effect with significant differences in the studied blood parameters and body growth was found in animals that received selenium citrate in the diet for 30 days at the rate of 200 μg/l. Feeding rabbits with different amounts of selenium citrate contributed to an increase in hematopoietic function, resistance and growth intensity compared to the control group. The use of selenium citrate in the diet of rabbits activated physiological and biochemical processes in the body, characterized by a higher number of red blood cells (P < 0.05), leukocytes (P < 0.05) and hemoglobin concentration (P < 0.05), higher body weight and BW, which was more pronounced in rabbits fed selenium citrate at doses of 100 and 200 μg/l for 30 days of the study.
