'Grasslands Lancelot' narrow-leaved plantain was bred by four generati
ons of selection from 109 seed populations, collected mainly from the
Manawatu region, New Zealand. Compared with this highly varied base ge
rmplasm, Lancelot is a rosette-forming cultivar but is more erect, den
sely-tillered, productive, and uniform. Lancelot has been evaluated in
pure and mixed swards under sheep grazing. The growth rate of animals
is not high from feeding on pure swards if the foliage is rank or at
the heading stage, both of which reduce intake. Carcass characteristic
s of sheep fed plantain are typical for their growth rates and the mea
t flavours/odours are typical of those fed grasses, less intense than
those fed legumes. Animal performances from plantain/legume mixtures h
ave matched those of other species in legume mixtures. There are indic
ations that Lancelot has several mild 'medicinal' effects: anthelminti
c activity in test tube assays (though not in grazing trials); antibio
tic effect on rumen flora; high levels of some minerals; and a diureti
c effect.Present results suggest the cultivar would best be used as a
component of mixed swards, particularly in dry regions, to add diversi
ty to the animal diet.
