Jungle rice is relished by livestock that graze it during summer. It also makes a very palatable hay (FAO, 2011). Literature about its nutritive value is scarce and includes studies with wild ruminant species. According to a gas production study, Echinochloa colona can meet the maintenance levels of ruminants (Ahmed et al., 2004).
In Spain, jungle rice mixed with Echinochloa crus-galli and Digitaria sanguinalis has been made into hay and fed to sheep in pear and apple orchards (Rodriguez, 1977).
In India, jungle rice did not meet the requirements of growing goats for digestible crude protein, Ca and P (Verma et al., 1995).
Wild ruminants species
Jungle rice is much appreciated by hippopotamuses, a very selective animal species, around the Niger River (Noirard et al., 2004).
In Zambia, the digestibility of jungle rice has been measured in lechwe (Kobus eche spp. kafuensis), an antelope species. Stem were found to be more digestible than the leaves, probably due to the high silicium content of the latter. Jungle rice could meet crude protein, K, Mg and Fe requirements of adult animals but could not meet P and Zn requirements (Rees, 1978).
