The purpose of the study was to investigate the effect of putting up for 58 days life of various amounts of nanosilicon citrate infusion obtained by the method using nanotechnology and metasilicate sodium, on the growth and development of the body of the rabbits of the Hyla 110 of the diurnal age. The rabbits of the control group fed without restriction a balanced granulated feed with free access to water. Animals of the experimental groups I, II and III fed feed of the control group's diet
... ol group's diet and, during the day, dispensed the citrus application, accounting for 25; 50 and 75 μg Si/kg body weight. The females of the IV and V experimental groups feed the diet of the control group and set the sodium metasilicate (Na2SiO3H2O) with water in an amount of 2.5 and 5.0 mg Si/kg body weight, respectively. The trial lasted 68 days, including a preparatory period of 10 days, an experimental one of 58 days. On the 110-th day of life, animals of all groups were killed to determine the mass indices of carcasses, internal organs and skin. Exposure of nanosilicon citrate to animals in the I, II, and III experimental groups during 58 days was characterized by an increase in body weight of 4.0; 9.5 and 8.9%, while the use of sodium metasilicate in IV and V groups increased by 3.1 and 4.2% compared with the control group. The carcass weight correlation was correlated with body weight and in animals of groups ІІ and ІІІ, respectively, was higher by 10.6 and 9.0%, while in other experimental groups it was greater in the range from 2.4 to 2.9% compared with control. Research on the development of the body of rabbits indicated a tendency to a higher level of body mass index and internal organs in animal experimental groups than in the control, although the more pronounced differences were in rabbits I–III groups, which were deposited on nanosilicon citrus application. Ribbons infusion of citrate in comparison with metasilicate of sodium and control group, to a greater extent influenced the mass of the skin and the mass of the liver, which was reflected in an increase (P < 0.05) of their mass on 110 days of life. The use of an organic compound of silicon in the amount of 50 and 75 μg Si/kg of body weight, during 58 days, contributed to the activation of metabolic processes in the skin. Perhaps higher (P < 0.05) indices of the thickness of the dermis and subcutaneous fat and the total thickness of the skin of rabbits compared with the control group were established. The conducted studies showed more pronounced positive effects on the growth and development of the body of rabbits of the organic compound of silicon in the amount of 50 and 75 μg Si/kg body weight in comparison with its inorganic compound and control group.
