Blood Meal

Blood meal contains mostly protein, small amounts of fat and ash. Unlike other animal protein sources, blood meal has a poor amino acid balance. Its lysine content is relatively high (7-10% DM) which makes it an excellent supplementary protein to use with plant-derived feed ingredients that are low in lysine. Blood meal is rich in iron.
Blood meal is valuable for ruminants due to its high protein content and rumen-resistant amino acids. Blood meal contains more essential amino acids than soybean. It should be supplemented with other protein sources.
