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

Abstract

The present study was conducted to explore the effects of graded replacing fishmeal (0, 50, 100 and 150 g/kg) with chicken plasma powder in diets for largemouth bass, and each diet was fed to triplicate groups of fish (initial weight: 49.50 ± 0.07 g) twice daily. Results showed that specific growth rate was not remarkably reduced until 150 g/kg fishmeal being replaced. Meanwhile, the inclusion of chicken plasma powder led to a significant decrease in feed intake, and the replacement of 150 g/kg fishmeal significantly decreased the apparent digestibility coefficient of protein and essential amino acids, which may account for the lowered protein retention rate and decreased crude protein content of liver and whole body composition. Moreover, the replacement of 150 g/kg fishmeal resulted in a significantly reduced activity of lysozyme, classical complement pathway and respiratory burst, and meanwhile, the red blood cell count and haemoglobin content were also significantly reduced, indicating the impaired health status of fish with high inclusion of chicken plasma powder. In above, approximately 50–100 g/kg fishmeal could be replaced by chicken plasma powder in the diets for largemouth bass.

Partial replacement of fishmeal with Clostridium autoethanogenum single‐cell protein in the diet for juvenile black sea bream ( Acanthopagrus schlegelii )

“…Meanwhile, there is a growing conflict between feed and human consumption on the utilization of plant protein. Chicken plasma powder could replace 50-100 g/kg fishmeal in the diets for largemouth bass (Micropterus salmoides) (Li, Ding, Wang, Sang, & Chen, 2019). Animal proteins such as insect proteins and poultry by-product meal usually have high protein and low carbohydrate content, but also have limitations such as poor palatability and unbalanced amino acids, which may inhibit feed intake and growth of fish when they are used to replace fishmeal at high levels in aquafeeds (Rapatsa & Moyo, 2017;Rossi & Davis, 2012).…”

Fishmeal could be replaced with 25% Tenebrio molitor larvae meal in the diet for Sparus aurata without negative effects on weight gain (Piccolo et al, 2017).…”

High dietary starch inclusion impairs growth and antioxidant status, and alters liver organization and intestinal microbiota in largemouth bass Micropterus salmoides

“…As a carnivorous fish, largemouth bass farming is developing rapidly in China, which is typically a more desirable fish to consumers. In recent years, the annual output of largemouth bass in China was up to 457 thousand tons (Li, Ding, Wang, Sang, & Chen, 2019). However, the application of formula feed has been a bottleneck problem in the farming of largemouth bass.…”

Effects of enzymatic hydrolysates from poultry by‐products (EHPB) as an alternative source of fish meal on growth performance, hepatic proteome and gut microbiota of turbot ( Scophthalmus maximus )

“…Enzymatic hydrolysates from plant and animal protein sources can improve their utilization efficiency by increasing the absorption of amino acids and mineral elements, and promoting protein synthesis efficiency and digestive enzyme activity, and thus can enhance growth rate (Khosravi et al., 2015; Li, Ding, Wang, Sang, & Chen, 2019). Enzymatic hydrolysis of proteins results in the formation of a mixture of free amino acids, di‐, tri‐ and oligo‐peptides, and enhances the occurrence of polar groups and the solubility of hydrolysate compounds, thereby improving feed palatability (Lasekan, Abu Bakar, & Hashim, 2013).…”
