The objective of the present study was to develop models for predicting live weight from length-weight relationship and body composition Nile tilapia. A total 3,000 juvenile fish (initial = 28.6±4.16 g standard length 13.8±0.16 cm) were distributed into three circular cages (12 m3 each). hand-fed extruded diets containing 332 kg-1 crude protein 3,230 kcal digestible energy, until apparent satiety, twice daily, 100 days. Twelve collected each cage every 20 days measurements length, proximate...
Threonine is the third-limiting essential amino acid in diets based on cereal ingredients. A 4-week trial was conducted to determine threonine requirement of large Nile tilapia fish growth, feed efficiency, body composition, protein and retention.

As foram aos vezes por dia, até aparente saciedade, durante 46 dias. Não foi observado efeito dos...
Abstract We assessed the nutritional value of corn in extruded diets for Nile tilapia, Oreochromis niloticus , by determining apparent digestibility coefficients dry matter, crude protein, and gross energy, measuring availability ( AACs ) essential non‐essential amino acids AAs several corn‐based diets. fed 180 juvenile tilapia a reference diet containing 325.8 g/kg protein 4613 kcal/kg energy or test 70:30 mixture ingredient (whole corn, germ, germ meal, gluten feed, meal). The ranged from...
Colliroja, Astyanax fasciatus, is a new aquaculture species, and information on its dietary essential amino acid requirements lacking. The whole body composition of 120 farmed fish (16.2 ± 8.8 g) was determined to estimate the requirement based ideal protein concept ((each acid/lysine) ×100), findings were correlated content Nile tilapia Oreochromis niloticus. acids, including cysteine tyrosine, accounted for 5.46, 4.62, 1.16, 3.28, 5.63, 2.01, 2.59, 2.84, 4.66, 3.39, 0.65, 3.51% total...
The dietary total and available requirement of tryptophan 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 crude protein 14.1 MJ/kg digestible energy. Five extruded 2.5, 3.0, 3.4, 3.8 4.2 evaluated. Fish four times a day during 45 days. Final body weight, weight gain, feed intake, conversion ratio net utilization Trp 3.4 improved compared to 2.5 diets. No significant differences in survival rate,...
Abstract Meat and bone meal (MBM) is an excellent source of amino acids (AAs) for fish but its proximate composition varies according to origin processing. Apparent digestibility coefficients (ADC) dry matter, crude protein, gross energy, apparent availability (AAC) essential nonessential AAs (EAA NEAA, respectively) in MBM containing various levels protein (MBM‐340, 370, 400, 430, 460 g/kg) were determined juvenile Nile tilapia ( Oreochromis niloticus , 32.7 ± 4.5 g). A reference diet 351.9...
