Nutrition experts said that from the perspective of nutrient composition, there is little difference between pig blood and duck blood in protein, vitamin and other contents. However, the contents of iron and potassium in pig blood are much lower than those in duck blood. According to the scientific research data, the iron content per 100g pig blood is 8.7mg, while the iron content per 100g duck blood is 31.8mg. In other words, the nutritional value of pig blood and duck blood is much worse than that of duck blood.
