Christmas trees goat food
can sheep and goats be fed old Christmas trees
Hillsborough County New Hampshire
Though they may eat it, I wouldn't recommend it. Pine needles are known to cause abortions in cattle. Although several studies have shown them not to cause abortions in goats, some suggest they may still be toxic to goats. They are also not very nutritious, being low in protein and high in volatile oils. There are much better feeds for goats.
