Abstract
The paper deals with the frequency of microelements and especially trace elements which appear in the soil and then in different ways migrate into forage plants. The aim of our experiment was to estimate the aluminium (Al), silicon (Si) and titanium (Ti) content in feedstuffs produced in northeastern (NE) part of Slovenia. We analyzed eight feedstuffs using X-ray fluoroscence spectrometry (K-18 compound feedstuff, hay which consists of Italian ryegrass, white clover and red clover, corn middlings, maize silage, grass silage, wheat bran, soybean cake 44 % CP, and dry beet pulp) in twenty replicates to ensure enough variability. The mean value of Al was 3.05×10-3 g/g DM, Si 6.06×10-3 g/g DM and Ti 5.22×10-5 g/g DM in all analysed feeds. The range between minimum and maximum value among eight feedstuffs concerning Si 2.27×10-2 then Al 7.93×10-3 and Ti 2.07×10-4. This basic research in the selected samples could be important for further research on the nutritional effects of microelements (Al, Si, Ti) on animals.
