The effect of silicon-containing substances on the digestibility of feed and energy exchange in the body of poultry

The article discusses results of studying effects of various doses of ultrafine particles of silicon dioxide (SiO2) on the body of broiler chickens, the dynamics of their live weight, digestibility of nutrients in their diet and the transformation of energy and protein of the feed into the body of an experimental bird. It is established that the use of ultrafine silicon in feeding broilers will increase live weight of the experimental poultry by 3.3-3.5 %, reduce feed intake by 0.7-2.1 %, increase the digestibility of dry matter of growth compound feed by 0.8-1.2 %, raw fat - by 0.2-1.0 %, crude protein - by 0.2-0.5 %, and also increase the net growth energy in MJ per head by 3.5-3.9 %, as a percentage of gross energy - by 8.7-14.3 %, while reducing feed energy loss by 4.0 % and 2.4 %. Therefore, our data reflect the productive effect of highly dispersed silicon oxide on poultry.
