摘要： The invention relates to a method for producing blood meal comprising the subsequent steps of (i) providing an aqueous mixture comprising raw blood, preferably having a solid content of between about 5 and about 18 wt %, and (ii) increasing the solid content of the mixture to obtain a mixture having a solid content of about 20 wt % or higher, preferably between about 20-80 wt % and (iii) concurrently drying and grinding the resultant mixture in an air turbulence mill, to obtain blood meal having an average particle size (d50) between 20 μm and 0.7 mm, a d90 of below 1 mm as measured with laser diffraction using a dry powder Beckman Coulter particle size analyzer, and an ileal digestibility of about 85% or higher preferably of about 87% or higher, and more preferably about 90% or higher. The invention furthermore relates to a coagulated blood meal product with high ileal digestibility.
