Influence of silicon compounds on the mineral elements content in tissues of rabbits’ organism

Abstract

The article presents the effect of drinking rabbits from 52 to 110 days of life silicon citrate obtained by the method using nanotechnology at the rate of 25; 50 and 75 µg Si/kg body weight and sodium metasilicate in the amount of 2.5 and 5.0 mg Si/kg body weight on the mineral elements content in the tissues of the organism. Significant differences between Calcium, Cobalt, Zinc, Ferum, Cuprum, and Manganese content in liver, muscle, tubular bone, skin, wool, and blood of rabbits were determined depending on the amount and compound of silicon in the rabbit diet. Feeding silicon citrate in the smallest (25 μg Si) of the studied quantity was indicated by a significant increase ( P <0.05–0.01) of Si in skin and wool tissues, Zn in skin, Ca and Fe in blood and Cu in rabbit liver. The use of silicon citrate at the rate of 50 and 75 μg Si/kg body weight caused unidirectional changes in the studied tissues of rabbits with a likely increase ( P <0.05–0.001) content of Ca, Si, Co, Zn, Fe and Cu in the blood rabbits. This may indicate the synergistic effect of the amount of organic compound applied to silicon, since despite significant fluctuations in the amount of silicon entering the body, its content in the blood remains stable. A significant ( P <0.05–0.01) increase in the content of Ca, Si, Co, Zn, tissue of the longest muscle of the back, Si and Zn in skin, Si in wool, and higher Co level in the tubular bone tissue compared to the control group was found. The content of trace elements in rabbit tissues for the absorption of sodium metasilicate in the amount of 2.5 and 5.0 mg Si/kg body weight retained significantly less influence of the probable differences compared to the control group with more pronounced influence of lower amount, in particu-lar: Ca, Si, Fe in blood, Co in liver, Si in muscle tissues, Ca, Si and Zn in wool and skin. The established changes in the content of macro- and microelements in the tissues of the rabbit organism mark tissue specificity and depend on the compound of silicon used and their amount in the diet. The synergistic effect of the use of silicon compounds was more pronounced than the effect of silicon citrate in the amount of 50 and 75 µg Si/kg body weight, which may indicate a stimulating effect of silicon on the correction of mineral metabolism in their body.
