Abstract
The most important factor that affect the quality of forages is their maturity. However, environmental factors determine the time when plants reach a certain degree of maturity. The effects of these factors can be seen in growing rate, development rate, yield and forage quality. According to season and year, the forage quality changes, even when the forages were harvested at similar maturity stages. If we want to predict forage nutritive value we have to know how the environmental factors affect the forage quality. The object of this research is to determine the effect of environmental factors that affect nutritive value of selected economically important grass and clover species. We will study the effects on chemical composition, in vitro digestibility, kinetics of in vitro fermentation (gas-Hohenheim- test) and kinetics of rumen degradability (in sacco degradability) and also relationships between them. Parameters of degradability kinetics became an integral part of modern protein and energy evaluation systems.
