Effects of replacing fishmeal protein by hemoglobin powder protein on growth performance, food intake, feeding-related gene expression and gut histology of hybrid grouper ( Epinephelus fuscoguttatus × Epinephelus lanceolatus ) juveniles

Partial substitution of soybean meal with faba bean meal in grass carp (Ctenopharyngodon idella) diets, and the effects on muscle fatty acid composition, flesh quality, and expression of myogenic regulatory factors

“…Significant differences were taken into account when p < .05. In addition, a quadratic broken‐line model was used to evaluate the maximum dietary SBM substitution with FBM for grass carp according to Yao et al () (SAS 9.0 software, SAS Institute Inc., NC).…”

Replacement of fishmeal by chicken plasma powder in diets for largemouth bass (Micropterus salmoides): Effects on growth performance, feed utilization and health status

“…Similarly, the supplementation of blood meal displayed negative effect on the FI of hybrid tilapia ( Oreochromis niloticus × Oreochromis mossambicus ) (Fasakin, Serwata, & Davies, ). Meanwhile, high dietary haemoglobin powder also significantly decreased the feed palatability and fish appetite through down‐regulating the expression of appetite‐stimulating‐related genes (Yao et al, ), which may account for the reduced FI in the present study. Although FI was significantly reduced with the inclusion of chicken plasma powder, PER was only decreased when 150 g/kg fishmeal was replaced, indicating the high nutrition value of this protein source.…”

“…Blood meal is in ample supply with high protein quality and relative balanced amino acids profiles, and the potential use of blood meal as protein sources in aquafeed has been well demonstrated in some previous studies (Luzier, Summerfelt, & Ketola, ; Martínez‐Llorens et al, ). Haemoglobin powder is a by‐product during the process of plasma extraction, and positive effects have been also observed in the replacement of fishmeal with haemoglobin powder (Martínez‐Llorens et al, ; Yao et al, ). The above result confirmed the feasibility of blood products as alternative protein sources to replace fishmeal in aquafeed.…”

“…The blood and haemoglobin meal, belong to animal by‐products, have been reported as alternative protein sources to replace fishmeal in gilthead sea bream ( Sparus aurata ) (Martínez‐Llorens et al, ) and hybrid grouper ( Epinephelus fuscoguttatus × Epinephelus lanceolatus ) (Yao et al, ). Plasma powder is a kind of slaughterhouse by‐products obtained from the plasma of farmed animal un‐coagulant blood using low‐temperature spray drying method.…”

Performance, digestibility efficiencies, gut and liver morphologies of snub nose pompano Trachinotus blochii fed spray‐dried haemoglobin meal as protein substitute for fishmeal

“…The optimum inclusion level of SHM in pompano diets was at 3.08% (5.87% of protein in the diet) The results are comparable with the study of Ribeiro et al, (2011) and Martínez-Llorens et al, (2008) wherein optimum growth of pirarucu A. gigas was achieved when diets contain up to 6% spray-dried blood meal (9.3% of protein in the diet) and 5% haemoglobin meal (9.2% of protein in the diet) for sea bream, Sparus aurata respectively. Moreover, haemoglobin meal inclusion level was limited up to 10% (17.4% of protein in the diet) in hybrid grouper E. fuscoguttatus × E. lanceolatus (Yao et al, 2018) diets and Nile tilapia, Oreochromis niloticus at 7.45% level (15.9% of protein in the diet) (Lee & Bai, 1997b). However, several species have exhibited positive performance parameters when higher inclusion level of haemoglobin meal was utilized for Japanese eel, Anguilla japonica, at 23.8% level (41.3% of protein in the diet) (Lee & Bai, 1997a) and common carp, Cyprinus carpio, at using blood meal at 14.89% level (33.2% of protein in the diet) (Song et al, 1995).…”
