Why/how are pigs used to find truffles? Do they have a natural affinity for them?
In: 700
The pigs do have some natural affinity for truffles. Pigs have a much better sense of smell then humans but not quite as good as dogs. However their sense of smell is more tuned for mushrooms then dogs. For finding truffles they are about the same or maybe the pigs is slightly better. In addition to this they are much easier to train as they normally eat mushrooms. And they tend to prefer truffles. So training a hog to find truffles is like training a dog to find steaks. But they still needs to be trained to ignore other things and also to indicate where the truffles are rather then digging them up for themselves.
