Benefits from Chloris gayana can also be found in the plant's growth. Ensiling of Rhodes grass has been little studied, since it is difficult to ensile due to its high moisture coupled with low contents of water-soluble carbohydrates, similar to other tropical grasses (Parvin et al., 2010). The decrease in nutritive value is higher before the first cut compared to subsequent cuts, possibly because of the early flowering habit of the species (Mbwile et al., 1997b).
