“…Poor PWG, FI and FE were observed in young grass carp fed valine-deficiency diet, as previously shown in juvenile Jian carp [8]. Ahmed and Khan [45] indicated that the enhancement of fish growth was due to the increased FI and FE. Correlation analysis showed that PWG was positively correlated with FI and FE (r 1 ¼ þ0.935, P 1 < 0.01; r 2 ¼ þ0.881, P 2 < 0.05), implying that the enhancement of young grass carp growth may be partly attributed to the fact that FI and FE were improved by optimum dietary valine.…”

“…Determining the optimum dietary protein for fish enables the formulation of diets that maximize protein retention and reduce nitrogen excretion, thus reducing the costs and environmental impacts of aquaculture (CYRINO et al, 2010, WEBB et al, 2010, AHMED & KHAN, 2004. Therefore, the objective of this study was to determine the level of protein in juvenile II fat nook rations that would lead to a better apparent digestibility coefficient (ADC), greater protein retention and lower ammonia excretion.…”

Digestibility, protein retention rate and ammonia excretion in juvenile fat snook (Centropomus parallelus) fed with different.Ciência Rural, v.47, n.7, 2017. INTRODUCTIONCentropomus parallelus (fat snook) is a marine fish that is highly valued for its meat, which has excellent organoleptic qualities and is low in fat and calories, rich in polyunsaturated fatty acids and white in color. However, despite its high value in domestic and foreign markets, the species has been threatened by predatory fishing and anthropogenic impacts (DUTKA-GIANELLI, 2010). For commercial breeding to become a reality, several types of scientific information are needed, including data on animal nutrition.In animal nutrition, evaluation of feed digestibility coefficient is important to maximize nutrient utilization, reduce production costs and minimize water pollution by reducing the amount of nitrogen, phosphorus and organic matter that is eliminated (CANESIN et al. 2012). Digestibility, i.e., the ability of an animal to digest and absorb the nutrients contained in the diet, is one of the criteria used to quantify the diets nutrient utilization efficiency (BERCHIELLI et al., 2011;POND et al., 2005).Protein is one of the most important nutrients in fish diets due to its role in growth, maintenance and reproduction as well as being an important source of energy (MARTÍNEZ-PALÁCIOS et al., 2007), so it should be included at adequate levels in the diet to ensure good protein efficiency (CARVALHO et al., 2010). When included in excess, protein results in increased ammonia excretion (SÁ et al., 2008)

“…Para juvenis de espécies herbívoras e onívoras, o teor de lisina na dieta é de aproximadamente 1,5 ou 5% da proteína da dieta, como pode ser observado nos trabalhos realizados por Santiago & Lovell (1988), com tilápias-do-nilo, Murthy & Varghese (1997), com carpa (Labeo rohita), Forster & Ogata (1998), com juvenis de flounder (Paralichthys olivaceus) (1 g), Fagbenro et al (1998), com o bagre africano (Clarias gariepinus), e Ahmed & Khan (2004), com a carpa (Cirrhinus mrigala).…”

RESUMO -Este estudo foi realizado com o objetivo de determinar a exigência de lisina digestível para juvenis de tilápia-do-nilo. Noventa e seis peixes revertidos sexualmente e com peso vivo inicial de 5,72 ± 0,10 g foram alimentados por 42 dias com quatro rações (29.51% de PB e 3.235 kcal de energia digestível/kg) contendo diferentes níveis de L-lisina HCl (0,1; 0,3; 0,5 e 0,7%, correspondendo a rações com 1,04; 1,27; 1,51 e 1,741% de lisina digestível, respectivamente).Os peixes foram distribuídos em 16 tanques com capacidade de 1.000 L cada um, em um delineamento inteiramente casualizado, com quatro tratamentos, três repetições e seis peixes por unidade experimental. Não foi observado efeito dos níveis de lisina sobre o índice hepato-somático, a gordura visceral, a sobrevivência e os teores de água e extrato etéreo na carcaça. A análise de Linear Response Plateau do ganho de peso e da conversão alimentar versus níveis de lisina digestível demonstrou estimativa de exigência de 1,56 e 1,44% de lisina digestível, respectivamente. Foi observado efeito quadrático sobre o rendimento de carcaça, que aumentou até o nível de 1,61% de lisina digestível. Considerando o desempenho, recomenda-se que dietas para juvenis de tilápia-do-nilo devem conter 1,44% de lisina digestível (5,23% da proteína da dieta). Palavras-chave: desempenho, exigência, lisina, Oreochromis niloticus Digestible lysine requirements of Nile tilapia juvenilesABSTRACT -This trial was carried out to determine the digestible lysine requirements of Nile tilapia juveniles. Ninetysix reverted fishes averaging initial weight of 5.72 ± 0.10 g were fed four diets (29.51% of crude protein and 3,235 kcal/kg of digestible energy) containing increasing levels of L-lysine HCl (0.1, 0.3, 0.5, and 0.7%), during 42 days. The following treatments were evaluated: dietary lysine levels of 1.04; 1.27; 1.51 and 1.741%. Fishes were allotted to 1000-L 16 tanks, as a completely randomized design with four treatments, three replicates and eight fishes per experimental unit. No treatment effects on hepatosomatic index, visceral fat, survival rate and water ether extract in the carcass were observed. The Linear Response Plateau analysis of weight gain and feed:gain ratio versus digestible lysine level yielded an estimated digestible lysine requirement of 1.56 and 1.44% for Nile tilapia juveniles, respectively. Quadratic effect of treatments on carcass yield that increased up to 1.61% of digestible lysine was observed. Considering the performance, it is recommended diets containing up to 1.44% of digestible lysine (5.23% of protein) for Nile tilapia juveniles.
