How is animal blood processed into animal feed?

After animal blood is processed into blood meal, it is a good protein supplement feed for livestock and poultry. Where there is no mechanized production or special production of blood meal, the home-made carrier blood meal can be made by the indigenous method. The method is: mix animal blood and wheat bran (rice bran or cake powder) in a ratio of 1.2:1, stir evenly, and then spread Put it on the concrete floor or mat and turn it over from time to time to let it dry naturally. Generally, it can be dried in 4-6 hours. After drying, it is crushed with an animal feed hammer mill grinder, packaged and stored, and it is the carrier blood meal. About 5% of blood meal is fed in the diet of pigs and about 3% in the diet of chickens.
