Abstract:

Nowadays, it is thought that animals need about 20 chemical elements including silicon. Recent findings show that this chemical element is indispensable in terms of maintenance of mineral homeostasis of bones. The lack of silicon led to decrease in the level of hydroxyproline and activity of basic and acid phosphatases and this chemical element, by its occurrence in zeolites (soda zeolite A) stimulates DNA synthesis in calcigerous cells and stops in vitro resorption of bones osteoclasts. Apart from basic influence on metabolism of connective tissue, silicon has also anti-cancerous, antyatherosclerosis and antydiabetic effects. In accordance with the authors, its low level in an organism can increase the risk of atherosclerosis and lead to a per acute and long-term form of ischaemic heart disease by, among others, having effect on elasticity in arteries. The aim of the analysis was to determine the influence of herbal mixture in a cow’s dose on the content of mineral components such as bio-available silicon, calcium and phosphorus in cow’s milk. The experiment was carried out on 64 dairy cows of the Polish Holstein-Frisian breed. By means of the analogue method, the cows were divided into 4 equivalent groups of 16. The experiment consisted of an 84-day experimental period. In the experimental period, on the other hand, the cows were fed with a total mixed ration of bulky feed and a concentrate with different content of herb’s mixture in the concentrate. The content of mineral components such as bio-available silicon, calcium and phosphorus was determined in feed, raw milk and blood serum. All experimental groups showed an increase in the content of bio-available silicon in blood serum and cow’s milk, even a 1%-additive of herbal mixtures caused some increase in silicon content in blood serum and cow’s milk. The results obtained proved legitimacy of using herbal mixtures in feed doses of dairy cows.
