Abstract
Hays were made from forage crops (Medicago sativa, Melilotus segetalis, Trifolium resupinatum, Secale cereale, hexaploid triticale, Avena sativa and Lolium multiflorum), cut at 3 stages of maturity, and fed to Merino sheep. Prediction of DM intake (r = 0.79) and digestibility (r = 0.57) from measurements of in situ degradation of DM and gas production were highest using multiple regressions.
