Fat powder can be a feasible lipid source in aquafeed for the carnivorous marine teleost golden pompano, Trachinotus ovatus

Dietary tributyrin modifies intestinal function by altering morphology, gene expression and microbiota profile in common carp ( Cyprinus carpio ) fed all‐plant diets

“…D1 diets included 120 g kg −1 FM and 500 g kg −1 PPB, while D2‐D5 diets included 670 g kg −1 PPB with tributyrin supplementation at 0.5 g kg −1 , 1.0 g kg −1 , 2.0 g kg −1 and 4.0 g kg −1 , respectively (Table 1). The diets were prepared, dried and stored as previously reported in detail (Xie et al., 2020). The dietary ingredients and proximate compositions were shown in Table 1.…”

“…Growth performance, feeding efficiency and morphological parameter over the 8‐week feeding experiment were evaluated by weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR), hepatosomatic index (HSI), viscerosomatic index (VSI), intestosomatic index (ISI) and relative intestine length (RIL). These above parameters were assessed by standard formulae as described previously (Xie et al., 2020).…”

“…The proximal compositions of the experimental diets and whole fish were analysed in triplicates according to the methods previously described (Xie et al., 2020). Briefly, moisture content was determined by drying samples in an oven at 105°C to constant weight.…”

Tilapia can be a Beneficial n-3 LC-PUFA Source due to Its High Biosynthetic Capacity in the Liver and Intestine

“…The production process and store of diets were the same as previously reported. 26 Fish Husbandry and Sampling. Tilapia GIFI (Oreochromis niloticus) juveniles were purchased from a local hatchery and acclimatized for 2 weeks in the aquaculture facility of the South China Agricultural University.…”

“…To assess growth, feed utilization, and somatic parameters of fish over the 10 week feeding experiment, the initial and final average weight, weight gain rate (WGR), specific growth rate (SGR), food conversion ratio (FCR), survival rate (SUR), condition factor (CF), viscerosomatic index (VSI), and hepatosomatic index (HSI) were computed with standard formulae, as previously reported. 24,26 Measurement of Serum Biochemical Indices. Contents of triglyceride (TG), non-esterified fatty acid (NEFA), total-cholesterol (T-CHO), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were analyzed by the enzymatic method, and the enzymatic activities of alkaline phosphatase (ALP), acid phosphatase (ACP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were analyzed using an enzyme-linked immunosorbent assay (ELISA) method.…”
