“…Four FB extracts (FB water extract, FB alcohol extract, FB proteins, and FB residues) were obtained through methods in our previous study (Ma et al, 2020). In short, shelled FB was ground into 60-um powder, mixed with distilled water, and adjusted pH to 9.0.…”

“…To maintain the activities of heat-sensitive components, moderate temperature (<55 C) was used throughout the extracting and formulating processes. In addition to the four experimental feeds (each weighing 16 kg) including FB water extract feed, FB alcohol extract feed, FB proteins feed, and FB residues feed, we used whole FB and commercial feed as controls (Ma et al, 2020). The nutritional components of these extracts and controls are shown in Table 1.…”

“…The activities of the serum enzymes, including glutamic oxalacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), alkaline phosphatase (AKP) and peroxidase (POD), were also measured by using GOT, GPT, AKP and POD reagent kits (Jiancheng, Nanjing, China), respectively. Absorbance was detected according to our previous methods (Ma et al, 2020).…”

“…Crisp grass carp (Ctenopharyngodon idellus C.et V), a high-quality grass carp fed solely on faba bean (Vicia faba) for 90-120 days, has been protected as the "China Geographical Indication Product" and its fillet products are exported to North America (Ma et al, 2020). Compared with ordinary grass carp, crisp grass carp has unique muscle qualities, such as increased hardness and springiness (Lin, Zeng & Zhu, 2009;Xu et al, 2020;Yu et al, 2020).…”

“…Our previous study isolated four types of faba bean extracts-FB water extract, FB alcohol extract, FB proteins, and FB residues-and examined their effects on the muscle quality of grass carp including increased hardness, collagen contents, and fiber density (Ma et al, 2020). The aim of the present study is to test the effects of these four FB extracts on the growth, hematology, hepatopancreatic function, and lipid metabolism of grass carp, in a 100-d feeding trial using six diets including commercial feed, whole faba bean (FB), and the four FB extract feeds (FB water extract feed, FB alcohol extract feed, FB proteins feed, and FB residues feed).…”

Faba bean (Vicia faba, FB) is known to improve the texture of fish meat but retards growth possibly by inducing hemolysis, hepatopancreas damage, and metabolic disorder. In this study, we used ultrasonic processing to isolate four FB extracts (water extract, alcohol extract, proteins and residues) and examined their beneficial and detrimental effects. These extracts were separately mixed with commercial feed and fed to grass carp (Ctenopharyngodon idellus) using whole FB and commercial feed as controls. After fish were fed one of the six experimental diets for 50 d and 100 d, we evaluated the growth and hematological parameters, activities of metabolic enzymes, hepatopancreatic histology and oxidative response, and lipid metabolism. Results showed that both whole FB and FB residues caused growth retardation and hepatopancreas damage (P < 0.05), whereas growth performance was improved in the FB water and alcohol extract groups compared to the whole FB group. Although the FB water extract negatively affected the number and morphological parameters of red blood cells (P < 0.05), the hematological damage was less pronounced than that of the whole FB group. Excessive hepatopancreatic fat accumulation was found in the whole FB, FB alcohol extract and FB residues groups. Moreover, serious hepatopancreas damages were observed in the FB residues group. These results suggest that the beneficial and detrimental components of FB were successfully separated in the four extracts, and the FB water extract would be the best choice for grass carp culture in terms of growth performance and health. The safety evaluation of the four FB extracts would facilitate further application of FB in aquatic feed.
