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...

A 120-days feeding trial using snub nose pompano Trachinotus blochii (1.01+/- 0.02 g) tested spray-dried haemoglobin meal (SHM) as an ingredient in six iso-nitrogenous (crude protein of 50%) and iso-lipidic (crude fat of 8%) diets; namely; a diet with 0% SHM (control) and five diets replacing fishmeal with SHM at 4; 8; 12; 16 and 20%. Weight gain percentage (WG%) significantly decreased (p < 0.05) when fish were fed diets with 12; 16 and 20% SHM inclusion levels. Feed conversion ratio and survival significantly decreased (p < 0.05) when fish were fed diets with 16 and 20% SHM inclusion levels. However; visceral somatic index; hepatosomatic index; condition factor and proximate composition were not affected (p > 0.05) by SHM inclusion levels.
