Pigs are omnivorous animals and can consume a wide array of food. While it is possible for pigs to eat fish fat, caution must be exercised. Fish fat contains omega-3 fatty acids, which are beneficial for humans but can be harmful to pigs in large quantities. Excessive consumption may lead to vitamin E deficiency and reproductive issues. Therefore, it is best to limit the intake of fish fat in pig diets to maintain their overall health and well-being.
