Fermented blood meal feed is gaining significant attention in the animal nutrition industry due to its high nutritional value and versatile applications. This product is made by fermenting fresh blood (which should be preserved with trisodium citrate) with wheat bran or rice bran in a specific ratio. A special fermentation starter, often referred to as "gold baby feed starter," is then added—this can be diluted with five times the amount of rice bran for better mixing. After a proper fermentation process, the mixture is dried to produce a high-quality feed ingredient.
The nutritional profile of fermented blood meal is impressive. It typically contains over 45% crude protein, with a digestibility rate exceeding 90%. In contrast, non-fermented spray-dried blood meal, while having a higher crude protein content (up to 84%), has a much lower digestibility—only around 16%. Additionally, the latter has an unpleasant taste that reduces its palatability. Fermentation not only enhances digestibility but also improves the overall nutrient balance. The resulting product is rich in essential amino acids like lysine and methionine, as well as enzymes such as α- and β-amylase and protease.
This makes fermented blood meal an excellent alternative to high-quality fish meal in feed formulations for pigs, chickens, fish, and shrimp. It helps reduce feed costs significantly while maintaining or even improving animal performance. With the implementation of fixed-point slaughterhouses in China, the availability of blood has become more consistent and abundant. According to data from 2005, China slaughters approximately 700 million pigs annually, producing about 2.1 million tons of blood per year. Considering a 22% solid content, this translates to roughly 462,000 tons of pure blood meal. With a collection efficiency of 30%, it's possible to produce up to 90,000 tons of blood meal, and even more when fermented. The economic potential of this product is truly remarkable.
