“…Moreover, fish fed high levels of leucine grew less, which could potentially indicate that an antagonistic effect of high levels of leu is present (Han et al, 2014). In rainbow trout, Yamamoto, Shima and Furuita (2004) confirmed that the antagonisms appear in tissue BCAA concentrations.…”

An 8-week feeding trial was conducted to investigate the impacts of dietary leucine on growth, hepatopancreas and muscle protein content and relative expressions of protein synthesis-related genes in juvenile gibel carp (5.2 g). Triplicate tanks of fish (22 fish per tank) were fed with a low (0.82%), middle (1.90%) or high (2.99%) leucine diet to apparent satiation three times a day. The results showed that the weight gain (WG) and feed efficiency (FE) of the fish fed with the 1.90% leucine diet had the highest values compared to those of other two groups (p < .05). Dietary leucine significantly affected the protein and lipid contents of the hepatopancreas (p < .05), but not muscle or the whole body composition of the fish. The amino acid contents (Arginine, Leucine, Methionine, Phenylalanine, Alanine, Aspartic acid, Glutamic acid and Proline) of the dorsal muscles of fish fed with a 1.90% leucine diet were significantly higher than those fed with a 0.82% leucine diet. Moreover, transcriptional levels of target genes of rapamycin (TOR), ribosomal protein S6 kinase 1 (S6K1), eukaryotic translation initiation factor 4E (eIF4E) and leucyl-tRNA synthetase (LARS) in the hepatopancreas were significantly up-regulated (p < .05), but eukaryotic translation initiation factor 4E-binding protein 2 (4E-BP2) was significantly down-regulated (p < .05) with the increasing dietary leucine levels. However, dietary leucine had no effects on the gene expressions of 4E-BP2 and S6K1 in the muscle of gibel carp. The present results indicate that dietary leucine led to a marked tissue-specific response on protein content in the muscle and hepatopancreas of gibel carp that is related to the TOR signalling pathway.

“…Interactive effects of several couples of indispensable amino acids have been reported previously (Alam et al, 2002a;Han et al, 2013Han et al, , 2014Zhou et al, 2011). But interactions between conditional indispensable amino acids, especially between some functionally related amino acids, are still unrevealed.…”

“…However, few studies are focused on the interactive effects between specific amino acids (Cheng et al, 2011;Dabrowski and Guderley, 2002;Gaylord et al, 2007;Takagi et al, 2001), which are considered to be important in understanding the functions and metabolisms of amino acids (Han et al, 2013(Han et al, , 2014Li et al, 2009). Taurine (Tau) and glutamine (Gln) which used to be considered as two of the dispensable amino acids, are considered as conditionally indispensable amino acids recently (Kim et al, 2008;Li et al, 2009;Park et al, 2002;Wu, 2009).…”

Summary A 60‐day feeding trial was conducted to evaluate the effects of dietary palm oil supplements on growth performances, hematology, liver anti‐oxidative enzymes and air exposure resistance of Japanese flounder, Paralichthys olivaceus (initial weights 2.56 ± 0.01 g). Five diets were tested wherein the dietary fish oil was replaced by palm oil at: 0% (Control), 20% (20%), 40% (40%), 50% (50%) and 60% (60%). After the feeding trial, the 20% dietary palm oil was shown to provide similar growth rates and feed efficiency with no negative effects compared to the control group (P > 0.05). Significantly lower growth rates and feed utilization were found in fish fed higher than 40% palm oil in the diet (P < 0.05). Except for total serum protein, the blood parameters, liver anti‐oxidative enzymes, stress resistance and proximate compositions of Japanese flounder were not altered, even with dietary palm oil up to 60% of the lipid source (P > 0.05). According to the present results, palm oil is a valuable lipid source substitute in Japanese flounder diets; around 20–40% fish oil can be replaced with palm oil with no negative effects.
