Uses
Dietary supplement
Blood meal can be used as a livestock dietary supplement and is mainly added to supply dietary lysine for cattle, fish and poultry. Prior to use, it is sometimes mixed with molasses.
Organic fertilizers
Blood meal, bone meal, and other animal by-products are permitted in certified organic production as soil amendments, though they cannot be fed to organic livestock. Blood meal is different from bone meal in that blood meal contains a higher amount of nitrogen, while bone meal contains phosphorus. Alternatives to Blood Meal include feather meal and alfalfa meal. Blood meal is sometimes used as a composting activator.
Pest control
Blood meal can be spread on gardens to deter pest animals such as rabbits.
