Resumo: | The objective of this research was to study the effects of methionine or lysine supplementation in diets with low protein level for growth of pacu Piaractus mesopotamicus (Holmberg) (Characiformes, Characidae). Diets were formulated as a basal diet presenting 22% crude protein (CP), 4100 kcal gross energy (GE)/kg, 0.42% of methionine and 1.16% of lysine and other six diets, with the same basic formulation, supplemented with 0.2%, 0.4% or 0.6% methionine or lysine. An eighth diet (control) contained 26% CP, 4100 kcal (GE)/kg, 0.48% methionine and 1.43% of lysine. The diets were administered ad libitum to 144 fingerlings with initial medium weight of 14.98 ± 1.16 g. Averages weight gain, gross energy efficiency retention and feed intake for the control treatment were significantly higher (P < 0.05) than those of smaller protein level diets. Averages protein retention efficiency were only higher (P < 0.01) in the diets supplemented with lysine, showing the advantages of lysine supplementation in diets with low crude protein level. A higher growth of pacu was confirmed with diets containing 26% of CP. |

Foram formuladas uma dieta basal com 22% de proteína bruta (PB), 4100kcal de energia bruta (EB)/kg, 0,42% de metionina e 1,16% de lisina e outras 6 dietas, com a mesma formulação básica, suplementadas com 0,2, 0,4 ou 0,6% de metionina ou lisina. Uma 8ª dieta (controle) continha 26% PB, 4100kcal EB/kg, 0,48% metionina e 1,43% de lisina. As dietas foram administradas à vontade a 144 alevinos com 14,98 ± 1,16g de peso médio inicial. As médias de ganho em peso, eficiência de retenção de energia bruta e dos consumos alimentares da dieta controle mostraram-se maiores (P < 0,05) que as das dietas de menor teor protéico. As médias de eficiência de retenção de proteína bruta só foram maiores (P < 0,01) nas dietas suplementadas com lisina, mostrando as vantagens da suplementação com lisina em dietas com baixo teor de proteína bruta. Foi confirmado um maior desenvolvimento do pacu com dietas com 26% de PB.Editora da Universidade Estadual de Maringá2008-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/234310.4025/actascianimsci.v24i0.2343Acta Scientiarum.
