ABSTRACT The growth of the Brazilian aquaculture has stimulated the development of the productive chain of native species, including marine environment. The objective of this study was to evaluate the growth performance of juvenile mojarra fish (Diapterus rhombeus) fed diets containing different concentrations of crude protein (32, 36, 40 and 44 g 100 g-1). The 80 juvenile mojarra (7.2±1.5 g) were kept in 16 circular tanks (150 L). The study design used was completely randomized with four treatments and four repetitions. The fish were fed four times a day. At the end of the experiment (60 days) the final weight, feed intake, weight gain (WG), feed:gain ratio (FGR), protein efficiency rate (PER), energy efficiency rate, specific growth, survival rate and,... |

Avaliaram-se níveis de lisina digestível em rações para alevinos de tilápia-do-nilo (Oreochromis niloticus), linhagem tailandesa, com base no conceito de proteína ideal. Utilizaram-se 432 alevinos com peso inicial de 0,98 ± 0,03 g, distribuídos em delineamento inteiramente casualizado, com 6 tratamentos, 6 repetições e 12 peixes por unidade experimental. Os tratamentos constaram de seis rações isoenergéticas (3.000 kcal de ED/kg de ração) e isoproteicas (39,14% de PB) contendo 1,50; 1,66; 1,82; 1,98; 2,14 ou 2,30% de lisina digestível. Foram avaliados o consumo de ração, o consumo de lisina digestível, o ganho de peso, a taxa de crescimento específico, a taxa de sobrevivência, a conversão alimentar, as taxas de deposição diária de proteína e gordura... |

The objective of the present study was to investigate crude protein reduction and the methionine+cystine and threonine to lysine ratios in diets for reversed Nile tilapia fingerlings (Oreochromis niloticus), Thai strain. Four hundred and twenty Nile tilapia fingerlings with an average initial weight of 1.83 ± 0.02 g were placed in a completely randomized design, with five treatments, seven replications per treatment and 12 fish per experimental unit, for 37-days. Two crude protein (CP) levels were evaluated (32 and 28%). The diet with 32% CP had methionine+cystine:lysine and threonine:lysine ratios of 63 and 74%, respectively. Three diets with 28% CP had methionine+cystine:lysine and threonine:lysine ratios of 63 and 74%, 60 and 74% and 60 and 69%,... |

The objective of this study was to determine the coefficients of apparent and true digestibility of protein and amino acids of five feedstuffs (corn, wheat bran, soybean meal, corn gluten meal and fish meal) in 900 sex-reversed Nile tilapia (Oreochromis niloticus) of the Thai strain during the growth phase, with an initial weight of 315±8.45 g. A total of 750 fish were distributed according to a randomized block design (repetitions in time) into five treatments with six replicates of 25 fish each. The remaining 150 fish were fed a protein-free diet to measure endogenous protein and amino acid losses in order to determine the true digestibility of these components. Each tested diet contained a single protein source, which consisted of one of the evaluated... |

Com o objetivo de avaliar o efeito dos níveis de metionina + cistina digestível, com base no conceito de proteína ideal, em dietas contendo níveis subótimos de lisina digestível (1,40%), foram utilizados 396 alevinos revertidos de tilápia (Oreochromis niloticus), da linhagem tailandesa, com peso inicial de 0,86 ± 0,02 g, em delineamento inteiramente ao acaso, composto de seis tratamentos, seis repetições por tratamento e 11 peixes por unidade experimental. Os tratamentos consistiram de cinco dietas com diferentes relações metionina + cistina:lisina digestível (59,5; 63,5; 67,5; 71,5 e 75,5%) e relação treonina:lisina digestível de 80,0%; e uma dieta contendo relação metionina + cistina:lisina digestível de 75,5% e treonina:lisina digestível de 85,0%, todas... |

ABSTRACT The objective of this study was to determine the digestible tryptophan requirement of tambaqui (Colossoma macropomum) fingerlings and its relationship with digestible lysine. A total of 300 tambaqui fingerlings with three initial weights (2.12 ± 1.19, 8.13 ± 0.75, and 15.18 ± 1.91 g) were distributed in a randomized complete block design, consisting of six treatments (0.225, 0.256, 0.288, 0.319, 0.350, and 0.381% of digestible tryptophan) and five replicates of 10 fish per plot. The tryptophan to lysine ratio was estimated using a 1.78% level of digestible lysine. Variables regarding performance, food efficiency, and body deposition of protein, fat, and ashes, and nitrogen retention efficiency were evaluated. Feed intake and nitrogen retention... |
