Hello Shana here int the tropics we have and use several native tree species, either by pruning or by letting the animals feed directly from the tree-shrub. My silvopasture operation is with cattle (brahman), natural pasture and shrubs, and in some occasions  we use leaf feeding from bushes or from pruning trees. 

Hi Shana, thanks for becoming my first friend on NING! Your project sounds amazing.  Where are you working in the tropics?
