An index greater than 1.000 indicates that the fibre digestibility of a cultivar is greater than that of the standard checks. Therefore, higher values are desirable. 3 rd and 4 th year alfalfa indexes indicate relative persistence among varieties on this list. The following table presents the yield performance of varieties following three years of rotational grazing in Ontario trials. Note that all recommended alfalfa varieties carry the risk of inducing bloat in grazing animals.
Caution is advised when alfalfa based mixtures are being pastured.
