“…In the present study, a tryptophan-deficient diet in Nile tilapia resulted in reduced growth and was considered one of the most limiting AA to nitrogen deposition (Figure 1). The recommendation of 4.26 g/ kg of tryptophan in the diet for the finishing phase was higher than that determined in other studies through dose-response or AA deletion method for juveniles of the species under study, being 3.1 g/ kg (Nguyen, Salem, Salze, Dinh, & Davis, 2019), 2.90 g/kg (Zaminhan et al, 2017) and 3.70 g/kg (Diógenes et al, 2016). This variability may be justified due to the different rearing conditions and form of analysis to estimate the requirements (Abidi & Khan, 2010;Ahmed, 2012; Coloso, Murillo-Gurrea, Borlongan, & Catacutan, 2004).…”

“…Tryptophan is an essential amino acid and a precursor of several compounds, including serotonin (5‐hydroxytryptamine) (Le Floc'h, Otten, & Merlot, ), an important neurotransmitter that affects physiologic functions and behavioural responses of fish (Basic et al., ; Martins et al., ), being successfully supplemented in diets to suppress aggression (Harlıoğlu, Harlıoğlu, Mişe Yonar, & Çakmak Duran, ; Höglund, Bakke, Øverli, Winberg, & Nilsson, ; Hosseini & Hoseini, ) and cannibalism in fish (Król & Zakęś, ). Dietary tryptophan supplementation also improves growth performance of fish (Ciji, Sahu, Pal, & Akhtar, ; Farhat & Khan, ; Pewitt, Castillo, Velásquez, & Gatlin, ; Zaminhan et al., ; Zehra & Khan, ), and its deficiency may increase the incidence of scoliosis, lordosis and eye cataracts in salmonids (Walton, Coloso, Cowey, Adron, & Knox, ).…”

Total and available tryptophan requirement of Nile tilapia,Oreochromis niloticus, fingerlings

The dietary total and available requirement of tryptophan of Nile tilapia fingerlings was determined using linear regression analysis. Six hundred fish (3.4 ± 0.0 g) were fed diets containing 296.4 g/kg of crude protein and 14.1 MJ/kg of digestible energy. Five extruded diets containing 2.5, 3.0, 3.4, 3.8 and 4.2 g/kg of total tryptophan were evaluated. Fish were fed four times a day during 45 days. Final body weight, weight gain, feed intake, feed conversion ratio and net protein utilization of fish fed Trp 3.4 and Trp 3.8 diets were improved compared to fish fed Trp 2.5 and Trp 4.2 diets. No significant differences in survival rate, whole‐body moisture and ash were observed. Whole‐body amino acid profile of fish fed different diets did not differ statistically (p > .05). Fish fed Trp 3.0 and Trp 3.4 diets showed higher tryptophan retention compared to fish fed Trp 2.5 and Trp 4.2 diets. Excepting blood glucose, no effects of dietary tryptophan on haematological parameters were observed. The dietary total tryptophan requirement of Nile tilapia fingerlings based on weight gain was estimated to be 3.4 g/kg (11.0 g/kg of dietary crude protein) or 3.0 g/kg of available tryptophan (11.0 g/kg of dietary digestible protein).

“…Many recent studies have evaluated the dietary requirements of amino acids such as leucine (Gan et al, 2016), lysine (Michelato et al, 2016), tryptophan (Zaminhan et al, 2017), and valine (Xiao et al, 2018); the revised dietary requirement figures provided by these studies are higher than those previously established for Nile tilapia. This trend is expected because genetic improvements have been successfully applied to improve the growth rate of Nile tilapia (Bentsen et al, 2017).…”

This research was conducted to determine optimal dietary histidine requirement of grow-out Nile tilapia, Oreochromis niloticus, based on muscle development, expression of muscle-growth-related genes, and blood parameters. Fish (n = 288, initial body weight of 64.17±0.53 g) were fed extruded diets with graded levels of histidine (4.23, 5.44, 7.17, 8.91, and 11.57 g kg −1), containing approximately 289 g kg −1 crude protein and 3565 kcal kg −1 digestible energy. The study followed a completely randomized design with five treatments and four replicates each, for 65 days. There was a quadratic effect of dietary histidine on final body weight, feed conversion, and net protein utilization, and the best values were optimized at 8.09, 7.88, and 7.33 g kg −1 , respectively. Feed intake, hepatosomatic index, survival, body composition, and blood parameters of total protein, glucose, triglycerides, cholesterol, hematocrit, and hemoglobin were not affected by dietary treatments. Predominance of hypertrophic growth and higher mRNA levels of myogenin and MyoD were observed in fish fed histidine from 5.44 to 11.57 g kg −1 compared with fish fed histidine at 4.23 g kg −1. The mRNA expression of myostatin was not affected by dietary treatments. The dietary requirement of histidine for grow-out Nile tilapia was determined at 8.09 g kg −1 , considering growth performance, muscle development, and gene expression responses.
