Production, growth and nutritive value of 6 forage species, i.e. Superdan, Jumbo, Nutrifeed, Nectar, Sugargraze and Ruzi, were determined at weekly intervals from 42 to 63 days after sowing. The results show that Nutrifeed was the most productive species for early growth while Superdan and Jumbo were intermediate and the rest were less productive. In terms of crude protein content in forage dry matter (DM), all species showed a high percentage of crude protein, ranging from 15.1 to 21.0 percent, on day 42 and day 49 after sowing. The crude protein percentage then dropped sharply at day 56. However, after 56 days of growing, only Ruzi had a reasonable crude protein percentage (14.6 percent). In terms of species sown, Nutrifeed exhibited the greater dry matter and crude protein yield, reflecting a high rate of early growth and a reasonable crude protein concentration. Nutrifeed, therefore, has good potential for use as forage for stock, particularly when the forage is in urgent need. However, for long-term advantage, a perennial grass such as Ruzi should be taken into account when a selection of forage for pasture is made.
