“…The survival of 100% of the fish and, there not having been observed any signs of external deficiency and erosion of the fins, corroborate other studies utilizing lysine in the diet (Dairiki et al, 2007;Abimorad et al, 2010;Dairiki et al, 2013;Ovie e Eze, 2013). According to Keembiyehetty and Gatlin (1992), lysine helps to produce anticodies and to prevent fins from eroding.…”

“…Nevertheless, some studies indicate that the use of free aminoacids as a protein source in the diet does not promote the same performance obtained with intact proteins (Bureau e Encarnação, 2006), corroborating the findings presented for tambaqui. Some factors may be related to the low performace displayed by juvenile tambaqui, such as, the use of free aminoacids in the diet, low palatability of the purified ingredients, diet pH, feeding frequency and antagonism between lysine and argenine (Montes- Girao and Fracalossi, 2006;Bicudo et al, 2009;Dairiki et al, 2013;Ovie and Eze, 2013). According to Bureau and Encarnação (2006) and NRC, (2011), the use of either purified or semipurified diets provides, for some species, a lower weight gains mainly related to the use of free aminoacids and the low palatability of the ingredients utilized in those diets.…”

Some Authors suggest that the arginina: lisina ratio imbalace may affect animal performace (Furuya et al, 2012;Dairiki et al, 2013). The same can be observed in the study of Furuya et al (2013) who utilized 1.43:1 arginina: lisina ratio in the diet for tilápia (O. niloticus) and found that ratio to have influenced the lysine requirement when compared to earlier studies undertaken with the same species, suggesting that ratio to be able to affect the animal's nutritional need.…”

“…Lysine is an essential amino acid for fish, limiting in many feed ingredients utilized in diets, presenting no endogenous synthesis and is found in higher concentrations in fish carcass and muscle. It is considered an amino acid exclusively oriented for body protein deposition and, its limitation in the diet can lead to growth and weight gain losses, thus deserving special attention in feed formulations for different speciess (Rollin et al, 2003;Dairiki et al, 2013;Ovie e Eze, 2013).…”

“…In Brazil, recent studies on aminoacids nutritional requirement in fish have utilized lysine as reference and focused their their research on some species, such as tilapia Oreochromis niloticus, dorado Salminus Brasiliensis, pacu Piaractus mesopotamicus and surubim Pseudoplatystoma spp (Dairiki et al, 2007;Bicudo et al, 2009;Abimorad et al, 2010;Bomfim et al, 2010;Prado, 2011;Furuya et al, 2012;Dairiki et al, 2013;Ovie and Eze, 2013). In this context, tambaqui Colossoma macropomum, the second most cultivated species in Bazil and the first amongst the native ones (44,56% in 2011) (MPA, 2013), still has few studies being addressed to its aminocid nutritional requirement.…”

Exigência de lisina e estimativa dos aminoácidos essenciais para tambaqui, Colossoma macropomum (CUVIER, 1818)ABSTRACT Four hundred-fifty (450) 7.7±0.06 g juvenile tambaqui were distributed in 500L boxes, fed a casein, gelatin and free amino acids-based semipurified diet containing six lysine levels (L-lysine HCL 0.9; 1.2; 1.5; 1.8; 2,1; 2.4% of the diet), in a completely randomized design, so that their lysine requirements could be determined. Findings demonstrated that diets with rising lysine levels did not influence the assessed zootechnical parameters.Tambaqui presented reduced consumption, low weight gains and high feed conversion with the use of the semipurified diet. This diet affected the hematological parameters significantly with no changes on total proteins and plasmatic glucose. The reduction on the plasmatic cortisol with the increase of lysine in the diet suggests the lower lysine levels to have had an influence on plasmatic cortisol level values. The reduced levels of triglycerides, cholesterol and body lipids with increasing lysine levels suggest a relationship of this amino acid with the accumulation of body lipids. Essencial amino acids demand estimated from tambaqui body amino acids content, showed to be similar to that found for other species and the lysine was estimated at dietary protein 6.0 and 6.2%, through the two utilized methods. The zootechnical performance exhibited by tambaqui, using semipurified diet for the lysine 0.9 to 2.4% interval in the diet did not allow its demand to be determined through dose-response method. RESUMOCom objetivo de determinar a exigência de lisina para o tambaqui, 450 juvenis (7,7±0,06 g) foram distribuídos em caixas de 500 litros, alimentados com dieta semipurificada à base de caseína, gelatina e aminoácidos livres, contendo seis níveis de lisina (L-lisina HCL 0,9; 1,2; 1,5; 1,8; 2,1; 2,4% da dieta), em delineamento inteiramente ao acaso. Os resultados demonstraram que as dietas com níveis crescentes de lisina não influenciaram os parâmetros zootécnicos avaliados. O tambaqui apresentou consumo reduzido, baixo ganho de peso e alta conversão alimentar com o uso de dieta semipurificada. Essa dieta afetou significativamente os parâmetros hematológicos e sem alterações nas proteínas totais e glicose plasmática. A diminuição no cortisol plasmático com o aumento de lisina na dieta sugere que níveis mais baixos de lisina influenciaram nos valores de cortisol plasmático. Os níveis reduzidos de triglicerídeos, colesterol e lipídios corporais com o aumento dos níveis de lisina sugerem uma relação deste aminoácido com o acúmulo de lipídios corporais. As exigências dos aminoácidos essenciais, estimados a partir do conteúdo de aminoácidos corporais do tambaqui, foram similares ao encontrados para outras espécies e a lisina foi estimada em 6,0 e 6,2% da proteína dietética pelos dois métodos utilizados. O desempenho zootécnico, apresentado pelo tambaqui, com uso de dieta semipurificada para o intervalo de 0,9 a 2,4% de lisina na dieta, não permitiu determinar a exigência ...
