Six iso-nitrogenous and iso-lipid experimental diets were formulated to evaluate growth performance, intestinal digestive enzyme activity and the transcript expression of nutrition utilization related genes of the pacific white prawn, Litopenaeus vannamei (initial average body weight: 0.45 ± 0.01...

A feeding trial was conducted to evaluate a new dietary protein Methanotroph (Methylococcus capsulatus, Bath) bacteria meal (BPM) on nutritional profile of Litopenaeus vannamei. The basal diet was formulated to contain 25% fish meal and then 15%, 30% and 45% of fish meal protein were replaced with...

This study was conducted to evaluate the effects of animal by-products on growth, digestive enzymes, disease resistance, hepatopancreas, and intestinal histological outcomes in Litopenaeus vannamei. Shrimp (initial weight [g] = 0.29 ± 0.01) were fed with four types of diets for 8 weeks: control...

Dietary Clostridium autoethanogenum protein (CAP) has the potential to replace fishmeal (FM), but excessive CAP substitutions will affect gut health. Bile acids (BAs) have multiple benefits, but little information is available on the effects of BAs on Pacific white shrimp (Litopenaeus vannamei) fed ...

An 8-weeks feeding trial was conducted to evaluate the effects of dietary cholesterol supplementation on growth performance, hemolymph biochemical parameters, cholesterol metabolism, intestinal health, and disease resistance of Pacific white shrimp (Litopenaeus vannamei) fed a low fishmeal diet....

Methanotroph (Methylococcus capsulatus, Bath) bacteria meal is a kind of bacterial protein meal (BPM) with an excellent nutrition profile. This study evaluated the effects of replacing fish meal (FM) with BPM on growth, antioxidant capacity, intestinal morphology, and gut microbiota of Pacific...

The present study aims to investigate the effects of ratios of fish-to-soybean oils in a low fishmeal diet containing Clostridium autoethanogenum protein (CAP) on the growth and metabolism of Litopenaeus vannamei. Four diet groups were designed and the basal diet (FM, 44% crude protein, 8.66% crude ...

It is an urgent problem to find suitable replacement of fish oil (FO) in aquatic feeds due to the stagnant production and rising prices of FO. To evaluate the substitution of vegetable oils for FO in the diet of Litopenaeus vannamei (L. vannamei), four diets containing FO, linseed oil (LO), soybean ...

A series of 8 weeks feeding experiment was conducted to estimate the suitable proportion of yeast hydrolyzate (YH) suitable for fishmeal in feed of Litopenaeus vannamei. Supplementation of YH were 0, 2.5%, 5.0%, 7.5%, 10% and 12.5%, respectively. The substitution proportions for fishmeal were 0,...

The shortage of fishmeal (FM) resources limits the healthy development of aquaculture. Developing new protein sources to replace FM in aquatic feeds is an effective measure to alleviate this situation. However, the application effect of new protein sources is greatly affected by water salinity,...
