We have old, well established elderberry trees inside some of our pig paddocks. Based on 4 years experience the low fruit is not particularly interesting to our pigs - our chickens will graze on low level fruit/leaves, our ducks eat the fruit on the ground and of course our sheep and goats decimate them. Pigs might not be a good idea for young trees as they will likely be more interested in rooting close to them or pushing them over when they attempt to scratch on them - even young pigs can bend/break young saplings. Our 3 year old boar (about 300kg) decided one day to root up and push over a 10 year old elderberry - thankfully not too much of a loss as we let our two sheep go at it and didn't feed them, the chickens or the ducks for a week!
Our ducks, chickens and geese all do well grazing/feeding under our trees -the ducks and chickens are always particularly active during autumn/spring with all the bugs in the leaf-fall.
