Blood Meal
Blood meal (/blʌd mi:l/) is a dry, inert powder made from blood used as a high-nitrogen organic fertilizer and a high protein animal feed.
Etymology
The term "blood meal" is derived from the product's composition. It is a meal or powder made from blood, typically that of cows or hogs.
Usage
Blood meal is used in gardening where it helps plants by providing a high amount of nitrogen, which aids in rapid growth and development. It is also used in animal feed due to its high protein content.
Production
Blood meal is produced through a process that involves collecting blood, usually from cattle or hogs, and then drying it to create a powder. The blood is typically a by-product of slaughterhouses, which means that the production of blood meal can be a way to reduce waste.
