This material is used in animal feeding for a long time because of its high protein content (min.87%). It made from pure pig blood. It helps to make a very good digestible, high protein and amino acid content bait which find carps very attractive. Additionally, it’s good adhesive and it gives a very dark brown-red color to the baits so the very shy carps accept our bait easier. Carp find this ingredient very attractive, as do Chub, Catfish and Bream.
