Optimization of mineral nutrition is a necessary measure aimed to maintain high productivity and health of animals, including beef cattle, which forages may lack minerals. The paper studies the action of nanosized forms SiO 2 , FeCo on health, ruminal digestion and elemental composition of ruminal fluid of animals. It is found that within the vitro studies the feed dry matter digestibility is maximum with the introduction of nanosized particles (NP) of SiO 2 in the concentration of 2 mg/ml. The results of morph-biochemical blood test (in vivo studies) show the activation of protein metabolism, lack of negative impact on animal health. The introduction of SiO 2 NP (II group) promotes the accumulation of silicon in ruminal fluid progressing in time: the difference with control group makes 3.8% and 31% in three and six hours respectively. The introduction of FeCo NP (III group) decreases the concentration of iron by 46% and 52% and cobalt by 40% and 50% in three and six hours respectively. SiO 2 NP stimulates dry matter digestibility thus affecting the fermentation activity of rumen microflora. The received results indicate the advisability of applying the suggested approach and require further study.
