Growing grasses in a mixture with legumes leads to more profitable
production, better quality of forages, an increase in soil biogenicity and fixation of
a significant amount of nitrogen. The experiment was established as a two factorial
trial by the method of randomized complete block design in three replications. Italian
ryegrass – monocrop (IR), red clover – monocrop (RC) and their mixtures – IR:RC
(15:5 kg ha-1), IR:RC (15:10 kg ha-1), IR:RC (20:5 kg ha-1) and IR:RC (20:10 kg
ha-1) were planted in November 2016, with the first cutting in the spring 2017 – on
May the 9th, and the second cutting in the early summer – on June the 22nd. The
aim of this study was to investigate the concentrations of phenolic compounds such
as condensed tannins in Italian ryegrass, red clover and their mixtures, as well as
their concentrations impact on protein degradability in the rumen depends on the
seeding rate in the mixtures and harvested in the spring and early summer. Results
obtained... in this study showed that higher concentrations of non-protein nitrogen
and soluble protein in forages harvested in the spring influenced higher rapidly
degradable protein concentration in investigated mixtures. The highest rumen
undegradable protein was determined in Italian ryegrass monocrop harvested in
early summer, and we assume that high condensed tannins concentration
influenced the slower protein degradability. Our recommendation for plant
breeders is that cultivars with higher content of condensed tannins should be
created and introduced in animal nutrition.
