This study evaluated the effects of increasing levels methionine (Met) supplementation on success almost total replacement fish meal (FM) with soybean (SBM) in diets for hybrid tilapia (Oreochromis niloticus × Oreochromis mossambicus). Fish were fed 70 days a FM-based diet (Diet1-positive control) or SBM-based supplemented graded DL-methionine (Diet2 to Diet7). Contrast dietary Met, concentration was created by supplementing Diet2-negative control 1.2 (Diet3), 2.4 (Diet4), 3.6 (Diet5), 4.8...
The main objective of this study was to evaluate the effect methionine supplementation when reducing fishmeal levels in diets for white shrimp (Litopenaeus vannamei). Tested consisted a positive control with 260 g/kg (D1), two negative controls 100 and no amino acid (AA) (D2) or supplemented lysine but not (D3), four additional 100g/kg increasing DL-Met (1.0, 2.0 3.0 g/kg) (D4, D5, D6) Met-Met (1.0 (D7). Each diet fed groups 30 8 weeks at daily rate 70 body weight. Reduction from down did...
Chromium (Cr) is an essential micronutrient for all animals, which also important component of glucose tolerance factor. The present study was conducted to evaluate the effect dietary Cr levels on growth, accumulation in tissues, and lipid metabolism insulin signal pathway juvenile mud crab. Six isonitrogenous isolipidic diets were formulated contain 1.4 (basal diet), 1.7, 2.0, 2.2, 2.6 3.7 mg kg−1 Cr, respectively. results indicated that crabs fed with 2.2 had highest percent weight gain...
A 62-day growth trial was conducted to determine the dietary Met requirement of pre-adult gibel carp (Carassius auratus gibeilo) (initial weight 51.0 ± 0.02 g). Six isonitrogenous and isoenergetic diets using fish meal, blood meal pea protein concentrate as sources supplemented with crystalline amino acids were formulated contain graded levels (4.44, 6.56, 8.55, 10.90, 12.79 15.05 g kg−1, respectively) at a constant cystine level 3.99 kg−1. The results showed that gain rate productive value...
Selenium (Se) is a crucial trace mineral in human nutrition, known for its various health benefits, including the enhancement of antioxidant defenses. Enrichment fish fillets with Se seen as an interesting strategy to reduce risk deficiency diets. While inorganic sources have been traditionally used supplement diets, organic forms demonstrated superior bioavailability and efficacy managing oxidative stress tissue retention rates compared their counterparts. The main objective this study was...
A growth trial was conducted to examine the effect of dietary digestible energy (DE) content on methionine (Met) utilization and requirement in juvenile Nile tilapia (Oreochromis niloticus). Ten iso-nitrogenous (288 g kg−1 protein) practical diets, with two DE levels (10.9 MJ kg−1; 12.4 kg−1) five supplementation (0, 1, 2, 4 6 kg−1), were hand-fed twice daily triplicate groups (initial body weight 8.95 ± 0.06 g) for 8 weeks. Weight gain (WG) specific rate (SGR) increased significantly...
Sustainable aqua feeds have become an urgent necessity for future-oriented aquaculture sector development, and especially mineral supply could be limited when diets are being prepared with low amounts of animal-based sources. Since knowledge about the efficiency organic trace supplementation in different species fish is limited, effects chromium DL-methionine African catfish nutrition were evaluated. Four commercially based increasing (0, 0.2, 0.4, 0.6 mg Cr kg-1) form Availa-Cr 1000 fed to...
The experiment was conducted to determine the effect of dietary DL-methionine addition in fish meal reduction diet for juvenile golden pompano (Trachinotus ovatus). trial comprises following 11 treatments. (i) D1 as standard formulated with main protein source. (ii) D2–D5 diets were replace soybean at 60, 120, 180 and 300 g kg−1, respectively, amino acid profiles (including methionine lysine) referred profile D1. (iii) D6-D9 same D2–D5, but without supplementation. (iv) D10 D11 D3 D5 diets,...
We examined if minimum water exchange could spare dietary methionine (Met) required for maximum growth performance of juvenile Litopenaeus vannamei reared in an intensive outdoor system. Shrimp 1.98 ± 0.13 g were stocked at 70 animals/m2 and 72 days 50 tanks 1 m3 under flow-through (14.4% a day) static (1.4%–2.9% green-water conditions 32.0 3.7 g/L salinity. Five diets with inclusion fishmeal supplemented dipeptide, dl-methionyl-dl-methionine, formulated to contain increasing levels Met,...
Abstract Objectives In the present study, we investigated effects of partial or total replacement dietary inorganic trace materials (ITM) with metal–amino acid complexes (MAACs) on immune response, antioxidant capacity, cytokine genes expression, and overall health status Nile Tilapia Oreochromis niloticus reared in in-pond hapas (mesh cages) under field conditions. Methods All-male an average initial weight about 90 g fish−1 were stocked into hapas, quadruplicates, at a density 60 fish per...
A 10-week study was conducted to evaluate the effect of feed allowance and graded levels dietary methionine (Met) on growth performance Litopenaeus vannamei. Juvenile shrimp 1.83±0.14 g were stocked in 42 outdoor green-water tanks 1 m3 under 120 m−2. Animals fed two allowances, regular 30% excess. Five diets with 30 kg−1 fishmeal designed contain 318±2 crude protein a minimum amount protein-bound Met. To achieve Met, control diet 4.6 Met or 8.9 + cysteine (M+C) supplemented 1.2, 2.2, 3.2,...
<title>Abstract</title> This study aimed to evaluate the effects of adding chromium-methionine (Cr-meth) chelate in extruded diets containing reduced protein content on growth performance, carcass composition, nutrient retention, and hematobiochemical responses Nile tilapia juveniles. The fish were fed with two control (no Cr-meth): positive (311 g kg<sup>-1</sup> crude protein, estimated 258 digestible protein) negative (255 207 protein). Another five experimental (mean 251 mean 204...
<title>Abstract</title> This study aimed to evaluate the effects of dietary supplementation with zinc amino acid complex (ZnAA) in reduced crude protein extruded diets for Nile tilapia juveniles. Fish (41.55 g) were fed on a regime apparent satiety randomized design (seven treatments and three repetitions) 250 L tanks nine weeks. There two control (no ZnAA), which categorized as positive (crude content 318.90 g kg<sup>− 1</sup>, estimated 264.52 1</sup> digestible protein) negative (low...
