A familiar farmyard animal that all ages know and love, pigs have been domesticated for thousands of years, and are a sub-species of their wild relatives, wild boar.
While it may be a given that pigs adore their grub, it's best to be careful about what types of food and treats they get their snout into. Essentially pigs will eat anything and everything they can find.
Pigs are omnivores and have 15,000 taste buds where humans only have 9000. This may explain why they are such fiends for food! Pigs will graze on grass and hay, but cannot survive on this alone and just like us, some prefer not to graze, so ensure this isn't the sole component of their diet.
The best nutrition for pigs should include a combination of pig nuts (commercial pig pellets) and a variety of specific fruit and vegetables. Healthy vegetables that are full of goodness for pigs include leafy dark greens, asparagus, kumara and parsnips.
Generally, avoid fish and meat, and be warned of foods that are toxic (such as apple/pear seeds, cassava, wild mushrooms and green potatoes, as these all contain toxins that can be harmful to pigs, such as cyanide).
