“…On the contrary, in another flatfish, turbot (Scophthalmus maximus), only 19% of protein-bound AA could be replaced by crystalline-AA without negatively affecting growth performance and feed efficiency (Peres & Oliva-Teles 2005). However, similarly to the present study, a dietary replacement of protein-bound by crystalline-AA up to 45% in gilthead seabream (Marcouli et al 2004) or 50% in rainbow trout (Rodehutscord et al 1995;Bodin et al 2012) was achievable without affecting fish . performances. Differently, other studies in fish indicated that comparatively with protein-bound amino acids including crystalline-AA in diet formulation negatively affects fish performance (Cowey 1992;Zarate & Lovell 1997;El-Haroun & Bureau 2007;Hauler et al 2007;Dabrowski et al 2010).…”

Effective replacement of protein-bound amino acids by crystalline amino acids in Senegalese sole (Solea senegalensis) juveniles

2013

The objective of this study was to evaluate the potential of free amino acids to replace protein‐bound amino acids in diets for Solea senegalensis juveniles. For this purpose, fish with 4.26 g mean initial weight were fed during 55 days with diets containing 500 g kg−1 protein and 100 g kg−1 lipid, based on fish meal and fish oil as main protein and lipid sources (control diet), or diets where 20%, 35% and 50% of fish meal were replaced by crystalline amino acids, using L‐lysine HCl as lysine source. To access the efficiency of the crystalline lysine source, another diet was formulated with 35% fish meal replacement but using L‐lysine sulphate instead of L‐lysine HCl as lysine source. Overall, growth performance, feed utilization, nutrient retention, whole‐body and amino acid composition did not show significant differences among groups. In conclusion, up to 50% protein‐bound amino acids can be replaced by crystalline amino acids in diets for Senegalese sole juveniles without negative effects in fish performance. Additionally, it was shown that L‐lysine sulphate and L‐lysine‐HCl may be used interchangeably by Senegalese sole juveniles, with the potential economic benefits involved.

Modelling the effects of dietary methionine level and form on postprandial plasma essential amino acid profiles in rainbow trout (Oncorhynchus mykiss)

Aquafeed formulation is susceptible to affect amino acid (AA) availability for metabolic functions. Statistical models were applied to quantify the effect of dietary methionine level (from 6.01 to 16.17 g kg À1 dry matter) and form (free, coated or bound) on postprandial concentrations of plasma essential amino acid (EAA) in rainbow trout. Twelve diets were formulated with pea and soya protein concentrate or fish meal as the main protein ingredients and were supplemented or not with increasing amount of either crystalline or agar-coated methionine. Fish were acclimatized to one of the 12 diets for 6 weeks before postprandial plasma sampling (six sampling points up to 36 h, seven fish each time), further analysed for EAA content. Using generalized additive models, we show that (i) dietary methionine level and form explained 74% postprandial methionine plasma variations and that (ii) the methionine dietary form and plasma concentrations significantly affected the plasma concentrations of the other EAAs. Finally, linear model revealed a positive relationship (R 2 > 0.9) between plasma concentrations of the three branched-chain AAs under the present experimental conditions. The results obtained add new information on the dietary effects on EAAs in the plasma availability and the interactions between them.

“…However, feed efficiency was relatively lower than studies reported for silvery‐black porgy juveniles fed protein‐bound diets (Mozanzadeh et al., , ). In this context, maximum incorporating level of CAA differ greatly among fish species ranging from 19% for turbot ( Scophthalmus maximus ; Peres & Oliva‐Teles, ) to 45–50% for Senegalese sole ( Solea senegalensis ), gilthead seabream and rainbow trout (Rodehutscord, Becker, Pack, & Pfeffer, ; Marcouli et al., ; Bodin et al., ).…”

Establishing the optimum dietary essential amino acid pattern for silvery-black porgy (Sparidentex hasta) juveniles by deletion method

et al. 2017

A 6-week feeding trial was conducted to estimate the optimum dietary essential amino acid (EAA) pattern for silvery-black porgy juvenile based on the AA deletion method. Eleven isonitrogenous and isoenergetic diets were formulated containing 60% of fish meal nitrogen and 40% of crystalline AA nitrogen. In the control diet, the EAA profile was made similar to fish meal protein. Ten other diets were formulated similar to the control diet but replacing 40% of each EAA by a mixture of non-essential amino acids. Triplicate groups of fish (initial body weight of 4.7 g) were handfed with the experimental diets, three times a day, to visual satiation, for 42 days. At the end of the trial, final body weight of all EAA-deficient groups was lower than that of control group, ranging from 6.3% of reduction with arginine-deficient diet to 39.4% of reduction with lysine-deficient diet, relatively to the control group. Based on the relationship between nitrogen retention and EAA intake of the control and EAA-deficient diets, the optimal dietary EAA profile for silvery-black porgy juveniles was estimated to be (g 16/g N): arginine 5.3, lysine 6.0, threonine 5.2, histidine 2.5, isoleucine 4.6, leucine 5.4, methionine + cysteine 4.0 (in a diet containing 0.6 cysteine), phenylalanine + tyrosine 5.6 (in a diet containing 1.9 tyrosine), tryptophan 1.0 and valine 4.6.
