Hay samples of Italian forages were used to study relationships between chemical composition, in vitro ruminal fermentation kinetics and digestibility. There was a strong positive correlation among parameters related to in vitro digestibility and gas production. Stepwise multiple regression analysis of in vitro digestibility with chemical composition showed the best prediction equations for Lolium multiflorum followed by Medicago sativa and permanent meadow grass.

Abstract
Hay samples of Italian forages were used to study relationships between chemical composition, in vitro ruminal fermentation kinetics and digestibility. There was a strong positive correlation among parameters related to in vitro digestibility and gas production. Stepwise multiple regression analysis of in vitro digestibility with chemical composition showed the best prediction equations for Lolium multiflorum followed by Medicago sativa and permanent meadow grass.
