Effects of dietary glucose and starch levels on the growth, apparent digestibility, and skin-associated mucosal non-specific immune parameters in juvenile blunt snout bream (Megalobrama amblycephala)

Effects of dietary carbohydrate level on growth performance, innate immunity, antioxidant ability and hypoxia resistant of brook trout Salvelinus fontinalis

“…(2014a) found that increasing dietary carbohydrate level might be useful for improving the protein utilization efficiency in brook trout. Similar results were also reported by some other researchers (Erfanullah & Jafri, 1995; Vásquez‐Torres & Arias‐Castellanos, 2013; Wang et al., 2005; Xia et al., 2018). On the contrary, some studies revealed that dietary carbohydrate did not cause protein‐sparing effect (Li, Wang, et al., 2015; Wang et al., 2016).…”

“…An appropriate dietary carbohydrate level has been shown to improve the growth performance and feed utilization in some fish species such as blunt snout bream Megalobrama amblycephala (Xia et al., 2018), grouper Epinephelus akaara (Wang et al., 2016), black carp Mylopharyngodon piceus (Wu et al., 2016) and golden pompano Trachinotus ovatus (Zhou, Ge, Niu, et al., 2015). Similar results were observed in the current study, whereby the highest FBW, WG, SGR and the lowest FCR were observed in 150DCL.…”

Effects of dietary carbohydrate types on growth performance, innate immunity, antioxidant ability and glucose metabolism of brook troutSalvelinus fontinalis

“…For instance, concerning to growth performance, at least four kinds of conflicting findings have been reported: 1. polysaccharides (such as starch) are the most effective carbohydrate sources (cobia, Rachycentron canadum Linnaeus, Cui, Zhou, Liang, Yang, & Zhao, 2010; gilthead seabream, Sparus aurata, Enes, Peres, Couto, & Oliva-Teles, 2010; starry flounder, Platichthys stellatus, Lee & Lee, 2004;grouper, Epinephelus lanceolatus, Lu et al, 2018; gibel carp, Carassius auratus gibelio, Tan, Xie, Zhu, Lei, & Yang, 2006); 2. monosaccharides (like glucose) are the most effective carbohydrate sources (gilthead seabream, Enes, Panserat, Kaushik, & Oliva-Teles, 2008; rainbow trout, Oncorhynchus mykiss, Hung & Storebakken, 1994;grass carp, Ctenopharyngodon Idella, Tian, Liu, & Hung, 2004); 3. starch products (like dextrin) are more effective carbohydrate energy sources than both starch and glucose (amur sturgeon, Acipenser schrenckii, Jiang et al, 2014; blunt snout bream, Megalobrama amblycephala, Ren et al, 2015); and 4. there are no significant differences between different types of carbohydrates (common dentex, Dentex dentex, Pérez-Jiménez et al, 2015; grouper, Epinephelus malabaricus, Shiau & Lin, 2001). It should be noticed that studies involving the same species of fish also might report inconsistent results (Enes et al, 2008(Enes et al, , 2010Ren et al, 2015;Xia et al, 2018). For instance, Enes et al (2008) indicated that gilthead seabream performs better with glucose than starch, but these findings could not be replicated in a second study (Enes et al, 2010).…”

Growth performance, digestive and absorptive capacity of on‐growing grass carp ( Ctenopharyngodon idellus ) fed with graded level of dietary fibre from soybean hulls

“…Furthermore, study found that dietary starch or digestible carbohydrate levels at 309.4–423.1 g/kg, 300.0–380.0 g/kg and 174.7–265.3 g/kg diet did not have a significant influence on the growth of grass carp (Chen et al., 2012; Guo et al., 2013; Li et al., 2014). In other fish species, the starch levels at 220.0–460.0 g/kg and 330.0–440.0 g/kg diet did not show a significant effect on growth of juvenile tilapia ( Oreochromis niloticus × O. aureus ) and juvenile blunt snout bream ( Megalobrama amblycephala ), respectively (Wang et al., 2005; Xia et al., 2018). Thus, we speculate that the present results are caused by different dietary fibre levels rather than digestible carbohydrate contents.…”
