“…In the present study, the lysine content was significantly lower in the plasma of fish fed diet with highest dietary arginine levels from 13.0 to 33.6 g kg -1 compared with those fed diets with arginine 8.3 g kg -1 in two sizes, so that the dietary high arginine level would probably result in the deficiency of lysine, which limited the growth of fish and affect the accurate requirement of arginine. Similar findings were observed in rainbow trout (Berge et al, 1999) and Atlantic salmon (Kaushik et al, 1988), which indicated antagonism between arginine and lysine at the various species of fish. However, using different fish species have yielded no convincing evidence of competition between lysine and arginine (NRC, 2011).…”

“…Arginine is one of the necessary amino acids for all fish species studied (NCR, 2011), which has played important physiological and nutritional roles (Alejandro and Delbert, 2000). It is impacted many metabolic pathways such as protein synthesis metabolism of glutamic acid , proline, synthesis of creatine and polyamines (Kaushik et al, 1988). In addition, arginine has been regarded as an EAA in diets of some fish species (Cowey, 1994), and arginine is treated as an efficient stimulant of growth hormone and insulin so that it indispensable in anabolic processes (Wan et al, 2006).…”

This trial was conducted to investigate the dietary arginine requirement in two sizes of blunt snout bream (Megalobrama amblycephala). Six isonitrogenous and isoenergetic (34% crude protein) diets containing graded levels of arginine from 8.3 to 33.6 g kg -1 . Triplicates of 30 fishes (body weight 52.50±0.18g) of size I or 20 fishes (body weight 101.85±1.85g) of size II were fed with one of six experimental diets. Specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER) and weight gain (WG) significantly increased with the increase of arginine levels from 8.3 to 23.5 g kg -1(size I) or from 8.3 to 18.1 g kg -1(size II), and thereafter, kept decrease. The alanine aminotransferase (ALT) was significantly decreased with increase in dietary arginine levels from 8.3 to 23.5 g kg -1in size I or 8.3 to 18.1 g kg -1 of the size II (P<0.05). Urea content first significantly increased (P<0.05), and showed the same trend in two sizes. Meanwhile, plasma arginine concentration of two sizes significantly increased with increasing dietary arginine from 8.3 to 23.5 g kg -1 (P<0.05), and significantly lower lysine content in plasma was observed in fish fed diets with arginine levels from 8.3 to 23.5 g kg -1 (P<0.05). Broken-line regression model analysis relation on the basis of SGR, the optimal dietary arginine requirement could be 20.3 g kg -1 in size I, and 17.9 g kg -1 in size II of dry matter, respectively. The results may explain the adverse effects of a deficient or an excess dietary arginine level on growth and health of fish in future. Furthermore, the present study also suggests that an optimum dietary arginine could play an important role in improving growth, and maintaining health for different size of fish, which would be useful in developing amino acid balanced commercial feeds for blunt snout bream.

“…Neste estudo, os melhores resultados de desempenho foram obtidos com as dietas contendo relação energia digestível:proteína digestível de 122:1 e 127:1 e relação lisina digestível:arginina digestível de 0,72:1 e 0,77:1, com as dietas contendo 25,2 e 24,3% de PD, respectivamente. Kaushik et al (1988), em estudo realizado com truta arco-íris, relataram que o aumento no conteúdo de arginina na dieta aumentou a digestibilidade desse aminoácido e diminuiu a digestibilidade da lisina, indicando que há competição entre esses aminoácidos para absorção no intestino delgado. Berge et al (2002), em estudo realizado com salmão-do-atlântico, observaram que o crescimento e a conversão melhoraram nos peixes alimentados com dietas contendo níveis limitantes de lisina e altos níveis de arginina.…”

RESUMO -Avaliou-se o desempenho de tilápias-do-nilo (Oreochromis niloticus) criadas em tanques-rede e alimentadas com dietas contendo 27,0 (controle); 25,2; 24,3 e 22,7% de proteína digestível. Aminoácidos cristalinos (L-lisina, DL-metionina e L-treonina) foram adicionados à dieta considerando o conceito de proteína ideal e simulando o perfil de aminoácidos da dieta controle. Os peixes (34,63±19 g) foram alimentados manualmente com dietas isoenergéticas (3.075 kcal de energia digestível/kg de dieta) até saciedade aparente, três vezes ao dia, durante 91 dias. Utilizou-se um delineamento inteiramente casualizado, com quatro tratamentos, três repetições e 25 peixes/unidade experimental. Não foram observados efeitos dos níveis de proteína digestível sobre o ganho de peso, a conversão alimentar, a taxa de eficiência protéica, o peso da carcaça eviscerada, o rendimento de carcaça, o peso e o rendimento de filé, a sobrevivência e o hematócrito. Houve efeito quadrático dos níveis de proteína digestível sobre o consumo; o maior valor foi estimado para a dieta contendo 24,41% de proteína digestível e excreção de nitrogênio, na qual o melhor resultado estimado foi obtido com peixes que receberam a dieta contendo 24,92% de PD. Com a redução nos níveis de proteína digestível, observou-se aumento linear na retenção de nitrogênio. É possível reduzir o nível de proteína digestível, de 27 (29,1% de PB) para 24,3% (26,6% de PB), em dietas para tilápias-do-nilo criadas em tanques-rede. Essa redução deve ser feita por meio da suplementação de aminoácidos (com base no conceito de proteína ideal), considerando o desempenho e o custo da dieta/kg ganho em filé. of CP) to 24.3% (26.6% of CP) in amino acid supplemented diets (based on ideal protein concept), for juvenile Nile tilapia, cultured in net pens, without adverse effects on growth performance, carcass yield and composition, hematological parameters and cost of diet/kg of fillet gain.Key Words: amino acid, ideal protein, nitrogen excretion IntroduçãoA tilápia-do-nilo (Oreochromis niloticus) é uma das espécies mais promissoras para a piscicultura, pelo rápido crescimento em sistema intensivo, pela rusticidade e por possuir carne com boas características organolépticas e filé sem espinhos intramusculares.

“…Similar results were observed for silver perch (89.5%) (Allan et al, 2000) and striped catfish (86.7%) (Da et al, 2013). According to Kaushik et al (1988), excess dietary arginine may decrease the lysine digestibility, because these two amino acids share the same carrier system in the intestines (Berge et al, 1999).…”

ABSTRACT. The use of alternative feeds aims to maintain productivity and reduce animal production costs. This objective of this study was to determine the nutritional value of peanut meal (PNM), as well as replacement of soybean meal (SBM) by PNM in diets for Nile tilapia, Oreochromis niloticus. To determine the apparent digestibility coefficients (ADC) of nutrients from the PNM, 40 fish (100 ± 4.3 g) were randomly distributed in four 250 L tanks and fed reference and test diets (50% PNM) plus 0.1% chromic oxide. Feces were collected by modified Guelph system. For the growth performance trial, 180 fish (13.4 ± 0.2 g) were randomly distributed in 30 200 L tanks and fed during 90 days with isoproteic (26.8% digestible protein) and isoenergetic (17.6 kJ g -1 digestible energy) diets containing replacement levels of 0, 25, 50, 75 and 100% of SBM digestible protein by PNM digestible protein. The experimental design was completely randomized with five treatments and six replicates. The ADC for protein from PNM was 90.9% whereas the ADCs for essential amino acids ranged from 88.7% for lysine to 97.6% for arginine. The feed conversion ratio was significantly affected when the SBM was totally replaced by PNM. The protein efficiency ratio, protein retention and whole-body protein content significantly decreased in fish fed diets containing PNM levels above 25% of PNM. Therefore, PNM can replace up to 25% of SBM without impairing juvenile Nile tilapia growth performance, feed efficiency, and body composition.
