Partial replacement of fish meal by several plant proteins with or without iron and lysine supplement in diets for juvenile Chinese sucker,Myxocyprinus asiaticus

Abstract

Two feeding experiments were conducted to evaluate the potential of fermented soybean meal (FSBM), corn gluten meal (CGM) and cottonseed meal (CSM) with or without lysine (L) and iron (Fe) to replace fish meal (FM) in practical diets of juvenile Chinese sucker. In experiment I, four experimental diets (430 g kg−1 crude protein on dry matter basis) were formulated. Diet containing FM as the main protein source was used as a control (Diet 1). Diets 2–4 had 300 g kg−1 FM protein replaced with FSBM, CGM or CSM protein without iron or lysine supplement. Fish (average weight, 1.82 ± 0.01 g) were hand‐fed twice daily for 8 weeks. In experiment II, juvenile Chinese sucker (average weight, 3.40 ± 0.08 g) were fed one of five experimental diets twice daily for 8 weeks. Diet 1 in experiment I was used as a control and Diet 4 in experiment I, with ferrous sulphate, with lysine or with both ferrous sulphate and lysine were used as the experimental diets (designated as FM, CSM, CSM+Fe, CSM+L and CSM+Fe&L, respectively). Results from the two feeding trials indicated that about 300 g kg−1 of FM protein can be replaced by FSBM, CGM or CSM with lysine supplement in Chinese sucker diets without adversely affecting growth. CSM with iron could not improve the growth performance. CSM without lysine supplement significantly affected the growth performance, body composition and digestive enzyme activities.

Effects of complete fish meal replacement by rice protein concentrate with or without lysine supplement on growth performance, muscle development and flesh quality of blunt snout bream (Megalobrama amblycephala )

“…However, either ML or CL supplementation was quite effective in improving the nutritive values of the RPC diet as fish fed both diets achieved similar results with FM group. Similar results were also observed in red sea bream ( pagrus major ) (Kader, Koshio, Ishikawa, Yokoyama, & Bulbul, ) and Chinese sucker ( Myxocyprinus asiaticus ) (Yu, Gong, Lin, & Yuan, ). In contrast, other studies indicated that dietary CAAs could not be efficiently used by some aquatic species compared to protein‐bound AAs (Hauler et al., ; Peres & Oliva‐Teles, ).…”

“…This result is similar to past research revealed that replacing fish meal by a mixture of different plant protein sources showed better growth performance in Nile Tilapia (Oreochromis niloticus L.) (Al-Thobaiti et al, 2018). Some studies also revealed that the used of soybean meal (Mo et al, 2016), cotton seed meal (Yu et al, 2014), seaweed (Gracillaria arcuate) (Al-Asgah et al, 2016) have significant effects on the growth of fish. The FCR and FE both are related to dietary protein intake and can be converted into fish weight gain (Koumi et al, 2009).…”

Improved utilization of soybean meal through fermentation with commensal Shewanella sp. MR-7 in turbot (Scophthalmus maximus L.)

“…The activity of intestinal digestive enzymes is an important indicator reflecting the ability of feed digestion [46]. In parallel with the aforementioned findings in ADC values, dietary FSBM also remarkably ameliorated SBM-induced decrease of the intestinal digestive enzymes (trypsin, lipase and diastase) activities.…”
