Abstract
Physical characteristics, milling resistance and leaf flexibility were estimated in 123 varieties of tall fescue (Festuca arundinacea) on cutting dates in June and September. Milling resistance gave an indication of physical structure of the whole plant and corresponded with crude fibre content. Milling resistance and leaf flexibility were inter-related. Correlation coefficients in June between digestibility in vivo and crude fibre, milling resistance and leaf flexibility were -0.59, -0.56 and -0.35, respectively. Corresponding values for September were -0.62, -0.29 and -0.13. Milling resistance could be applied as an objective, relatively simple and low-cost laboratory method for predicting voluntary intake of tall fescue.
