Performance, Digestibility Efficiencies, Gut and Liver Morphologies of Snub Nose Pompano Trachinotus Blochii Fed Spray-Dried Haemoglobin Meal as Protein Substitute for Fishmeal
Spray-dried haemoglobin meal; a by-product and derivative of the swine processing industry; is formed when haemoglobin is separated hygienically from pig's blood. A 120-days feeding trial using snub nose pompano Trachinotus blochii (1.01+/- 0.02 g) tested spray-dried haemoglobin meal (SHM) as a...
