A combination of rapeseed, cottonseed and peanut meal as a substitute of soybean meal in diets of Yellow River carp Cyprinus carpio var

Abstract

A feeding trial was conducted to evaluate the results of replacing soybean meal (SBM) with other blend plant protein (BP) (rapeseed meal, cottonseed meal and peanut meal) sources on growth, fish body composition, biochemical parameters, non‐specific immune index and gene expression of growth hormone/insulin‐like growth factor‐1 in Yellow River carp Cyprinus carpio. The results showed that the 600 g/kg replacement with BP in diet did not affect the growth performance of Yellow River carp, but the 800 g/kg SBM replacement diet could depress the growth of fish (p < .05). The 800 g/kg SBM replacement diet significantly impacted the superoxide dismutase, malondialdehyde contents, lysozyme, alanine aminotransferase and aspartate aminotransferase activities (p < .05). Fish fed 800 g/kg SBM replacement diet showed lowest insulin‐like growth factor 1 and highest growth hormone level than that of other diets (p < .05). Both gene expression levels of GH and IGF‐I in hepatic showed significant difference among dietary treatments (p < .05), and the lowest GH and IGF‐I mRNA level in liver were found in fish fed 800 g/kg SBM replacement diet (p < .05). In conclusion, no more than 600 g/kg SBM could be replaced by BP in diet of Yellow River carp without adverse effects on the growth performance. However, 800 g/kg SBM replacement with BP in diet inhibited the growth performance, affected some blood parameters and immune response index, and down‐regulated GH and IGF‐1 gene expression of liver in Yellow River carp. Further, GH level in serum was negatively correlated with GH mRNA level in liver; meanwhile, serum concentrations of IGF‐I were positively correlated with hepatic IGF‐I mRNA expressions.

Effect of replacing dietary soybean meal with pumpkin (Cucurbita pepo) seed cake on growth, feed utilization, haematological parameters and fatty acid composition of mirror carp (Cyprinus carpio)

“…In contrast to our study results, López et al (2015) reported that dietary soy protein concentrate (SPC) caused a decrease in the ALB/GLB ratio in totoaba (Totoaba macdonaldi). Fish fed with the SPC-based diets may have Wang et al, 2020). In this study, ALT and AST values were similar among treatments, indicating that replacement of PSC with SBM had no negative effect on liver function in carp.…”

“…Niroomand et al, (2020) also showed a remarkable reduction in CHO and TG contents of shrimp (Litopenaeus vannamei) fed diets with different levels of black cumin seed meal. However, TG and CHO were not affected in C. carpio fed diets in which SBM was replaced by mixed plant protein (Wang et al, 2020). In our study, the decrease in CHO and TG levels may be related to the presence of phytosterol components in PSC, as stated by Niroomand et al (2020).…”

Effects of nonstarch polysaccharide hydrolase of plant protein‐based diets on growth, nutrient digestibility, and protease/amylase activities of Yellow River carp, Cyprinus carpio

“…After each feeding, when the fish were dispersed, the unconsumed feed was collected immediately with plastic nets and were then dried and weighed. The fish were fed thrice daily (T. T. Wang et al, 2020). Water quality parameters included temperature of 25 ± 2°C, 7.3 ± 0.3 pH, 5.8 ± 0.4 mg/L dissolved oxygen, <0.06 mg/L ammonia‐N, and 0.03 mg/L nitrite‐N.…”

After the feeding experiment, the fish were fasted for 24 hr, the total weight of the fish in each aquarium was measured, the feed intake of each tank was recorded, and the growth performance index of each group of fish was calculated (Xu et al, 2019).…”

Complete Replacement of Fishmeal With Plant Protein Ingredients in Gibel Carp (Carassius auratus gibelio) Diets by Supplementation With Essential Amino Acids Without Negative Impact on Growth Performance and Muscle Growth-Related Biomarkers

“…The addition of FM is low in the commercial feed formulation for omnivorous species. However, studies shown that FM was still the most optimal protein source in the diet and leads to the best growth performance for omnivorous species, such as tilapia (Oreochromis niloticus, Ahmad et al, 2020;Ismail et al, 2020) and carp (Cyprinus carpio, Wang et al, 2020), even herbivorous species, such as grass carp (Ctenopharyngodon idella, Jiang et al, 2016). Few reports are available to guide the total replacement of FM by plant ingredients in Cyprinidae species, which are widely cultured in China.…”
