Abstract
The feed cost represents the major cost in milk production. Direct grazing and forage produced on the dairy farm could allow
the farmer to a better feed production cost control. Ryegrass have been extensively used for grazing and forage production. This
study evaluates the production and nutritional composition of two ryegrass cultivars diploid and tetraploid alone or in a binary
mixture (50:50). The results showed that the binary mixture is a good option because of its higher production of DM/ha, higher ME
and NFC and lower content of NDF, ADF and ADL.
