: The aim of the experiment was to determine the effect of foliar application of Tytanit, a stimulator based on titanium, on the content of fibrous fractions, cellulose, and hemicellulose in the cell walls of h. alfalfa and r. clover. The experimental factors were plant species and titanium doses. The content of cell wall fibrous fractions was determined with near-infrared spectroscopy, and Relative Feed Value (RFV), and cellulose and hemicellulose content were calculated based on acid detergent fibre (ADF), neutral detergent fibre (NDF) and acid detergent lignin (ADL). The stimulator differentiated the content of fibrous fractions in plant cell walls. Its largest dose lowered ADF content to 2.3% in plant dry matter, and the smallest one increased accumulation of the ADL fraction by 1.6%. NDF content in the dry matter of h. alfalfa and r. clover was lower than the desired optimum for plants used as forage, and the stimulator additionally reduced it by 4.9%. Higher doses of titanium decreased carbohydrate content during unfavourable hydrothermal conditions. However, there was no significant effect of differentiated Tytanit doses on the RFV value.
