However, the evolution of milk production during the experiment was not reported, although the cows produced 8.7 kg milk/d at the beginning of the experiment (Mbwile et al., 1997b). It can grow up to 20 meters tall. Rhodes grass spreads readily in rainforest fringes in Queensland (Australia), where it produces seeds profusely and develops so quickly that it smothers native species and forms almost pure stands (DPIFQ, 2007). The leaves are a grey-green color. Also, its habitat doesnt get enough rainfall, so it cant be considered as a prairie. And each tree produces male and female flowers, which are carried on different parts of the fronds. The leaves are dark green and have a hard, rough surface, hence its common name sandbox tree. It produces hairy edible fruits and seeds. Silages from tropical forages. The bark of most acacias is also rich in a substance called tannin, used to treat leather and process dyes. 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).

It was recommended to allow for 30 to 50% of refusals, depending on maturity, so that the animals could select the most digestible parts. Young Rhodes grass of 4 weeks of regrowth or less was found to have a highin vitroOM digestibility of 70-80% (Mbwile et al., 1997a;Mero et al., 1997), which decreased to 50% after 10 weeks of regrowth (Mero et al., 1997). The stand begins to produce valuable forage within 6 months, though the highest yield is obtained during the second year of cultivation (FAO, 2014;Cook et al., 2005).
