Blood Meal

详情

Blood can be collected during the slaughter of various livestock species (cattle, pigs, chickens, etc.) under a wide range of conditions. It is usually dried and made into blood meal so that it can be handled and incorporated into rations more easily. Other feed products derived from blood include fresh blood, hemoglobin and plasma. Blood meal contains mostly protein and is used to supplement diets based on cereal grains, plant by-products and forages. It has been shown to be a satisfactory replacement for other protein sources in various animal production diets for dairy cattle, beef cattle, sheep, pigs, poultry, various fish species and silkworms. However blood meal is not very palatable and its amino acid content is imbalanced (see Nutritional attributes on the "Nutritional aspects" tab). It is not advisable to include high rates of blood meal in livestock diets.
