Due to lack of information on the use non-protein energy sources in diets for pacu (Piaractus mesopotamicus), a 2 × 3 factorial experiment was conducted evaluate performance and digestibility 12 containing approximately two crude protein (CP; 220 250 g kg−1), lipid (40 80 kg−1) three carbohydrate levels (410, 460 500 kg−1). The juveniles-fed kg−1 CP did not respond (P > 0.05) increased dietary levels, but fish-fed showed better feed conversion ratio. There were interactions weight gain (WG),...
This study proposed the use of stable isotope technique to track type food utilized by pacu Piaractus mesopotamicus larvae during their development, and identify moment when start using nutrients from dry diet retaining its carbon nitrogen atoms in body tissues. Five-day-old at onset exogenous feeding were fed Artemia nauplii or formulated exclusively; nauplii+formulated entire period; weaned a after 3, 6 12 days first feeding. δ13C δ15N values for −15.1‰ 4.7‰, respectively, −25.0‰ 7.4‰...
To determine the digestible lysine requirement for pacu juveniles, a dose–response feeding trial was carried out. The fish (8.66 ± 1.13 g) were fed six diets containing levels: 6.8, 9.1, 11.4, 13.2, 16.1 and 19.6 g kg−1 dry diet. gradual increase of dietary levels from 6.8 to 13.2 did not influence average values parameters evaluated (P > 0.05). level significantly improved weight gain (WG), specific growth rate (SGR), protein productive value (PPV), efficiency (PER), apparent feed...
The apparent digestibility coefficients (ADCs) of amino acids (AA), protein, and energy in six feed ingredients (Brazilian fish meal, soybean corn gluten alcoholic yeast, corn, wheat bran) we evaluated for pacu juveniles. In general, all showed high values AA, differences among ADCs individual acid were detected (P < 0.01). Corn gluten, soybean, meals had the highest AA. protein meal should not be used as AA indicators, because those up to 6.7% between All lower than Lysine was first...
Este experimento foi conduzido, por um período de 100 dias, com o objetivo estudar diferentes fontes e níveis proteína bruta em dietas para juvenis pacu. Foram utilizados 252 pacu, distribuídos 36 caixas cimento amianto volume 150 litros, sendo estocados sete peixes cada unidade. Durante experimental, a temperatura média da água permaneceu 28ºC os demais parâmetros limnológicos (oxigênio dissolvido, pH, alcalinidade condutividade) apresentaram-se dentro dos adequados desenvolvimento desta...
Para melhorar a alimentação do pacu (Piaracatus mesopotamicus), é necessário conhecer o nível de aproveitamento dos ingredientes utilizados em suas dietas. Neste trabalho, inicialmente, foram analisados quatro métodos coleta fezes, função da precisão e versatilidade (dissecação, extrusão, Guelph modificado), tempo entre as coletas fezes nos sistemas Guelph, por intermédio coeficiente digestibilidade proteína bruta uma dieta-referência para pacu. Não houve diferença os fezes; já intervalos...
The use efficiency and feed conversion of extruded pelletized diets were compared. Eight isoproteic (220 g kg⁻¹ digestible protein) assayed for 90 days in a 2 x multifactorial design with two carbohydrate levels (400 500 kg⁻¹), lipids (40 80 kg⁻¹) diet processing (pelletization extrusion) three repetitions. growth Piaractus mesopotamicus fed these the quality control indices gauged. density was lower as level 400 lipid 40 kg⁻¹. interaction presented higher leaching value low diet. Fish best...
Decoupled FLOCponics (DFP) is a promising aquaponics approach which takes advantage of the nutritional benefits biofloc technology (BFT). Enabling use less protein in fish diets one BFT. The effect reduction content, and consequently input nitrogen, on plant production DFP systems has not yet been investigated. This study was designed to investigate evaluate lettuce tilapia juveniles system using different levels crude (CP) diets. zootechnical performance growth were evaluated, containing...
To verify the potential of lipids and carbohydrates to spare dietary protein understand intermediary metabolism interaction these nutrients in pacu juveniles, an experiment was carried out evaluate physiological performance parameters. The experimental design completely randomized with 12 treatments a 2 × 3 factorial arrangement, consisting diets containing two digestible levels (200 230 g kg−1 PD), lipid (40 80 kg−1) three carbohydrate (410, 460 500 kg−1). Fish-fed digestable (DP) showed...
The use of dietary protein can be optimized by increasing diet energy, which achieved adding non-protein nutrients such as carbohydrates and lipids. If incorporated in suitable amounts, these items promote the sparing effect, reducing nitrogen excretion improving quality fish farming effluents. study assessed productive performance, body composition, nutrient energy retention efficiency digestibility omnivorous tambaqui (Colossoma macropomum) fed diets with three carbohydrate (410, 460 510 g...
Abstract Three types of raw materials including commercial waste from saltwater (SW), freshwater fish (FW) and tilapia fillet residue (FR) were used to produce silage by either acid digestion (2% formic 2% sulfuric acid) or anaerobic fermentation (5% Lactobacillus plantarum 15% sugar cane molasses). Six test diets in digestibility trials prepared with 70% reference diet 30% each experimental silage. These fed juvenile pacu Piaractus mesopotamicus (146 g average weight) triplicate. Fish kept...
Abstract Fish meal has been the most common animal protein source used to feed fish, even though it is fairly expensive and seasonally available. The objective of this work was investigate co-dried fish silage as an alternative for diets pacu, Piaractus mesopotamicus.The did not differ significantly (P >0.05) with respect average weight gain, ration consumption, apparent conversion, efficiency specific growth rates. However, digestibility productive values were different <0.01). Diets...
Several investigations have been carried out to improve the productivity of tambaqui, an economically important fish species in Brazil and other Latin American countries. This study determined digestible protein (DP) requirements juvenile tambaqui by assessing their productive performance nutritional efficiency. It also evaluated effects different dietary DP levels on morphology cellularity skeletal fast muscle fibres. The 1750 tested (6.53 ± 0.43 g body weight, 7.58 0.18 cm length) were...
O presente trabalho foi desenvolvido com o objetivo de determinar os coeficientes digestibilidade aparente da proteína e energia dos principais alimentos utilizados na formulação dietas para alevinos pintado. Foram 600 peso médio inicial 9,80 ± 1,48 g comprimento total 13,00 1,00 cm. Na coleta fezes, utilizado sistema Guelph modificado. As 12 dietas-teste foram constituídas por 69,50% uma dieta referência, 0,50% óxido cromo (marcador inerte) 30% do ingrediente estudado. Após receberem as...
