Resumo: | In this trial the requirement of threonine for the jundiá (Rhamdia quelen) was studied during the initial growth phase. Therefore a dose response experiment with five threonine inclusion levels (1.6, 2.2, 2.8, 3.4, 4.0% crude protein (CP)) and four replications was performed. The mixed diets were isonitrogenous (37% CP) and isocaloric (3400 kcal / kg estimated digestible energy). Juvenile jundiás (initial weight 4.47 ± 0.39 g and 8.16 ± 0,49cm length) were subjected to 70 experimental days, fed three times a day until apparent satiation, and their consumption calculated on a daily basis. Water quality parameters levels were kept optimal for the specie. Every twenty one days biometry was performed to evaluate the parameters of weight, weight gain, specific growth rate and feed conversion ratio. Body composition, nutrients deposition, metabolic, and enzymatic parameters were evaluated at the beginning and end of the trial. The data were submitted to normality test, analysis of variance, polynomial regression, and segmented regression. Then was chosen the analysis that best fits the data by comparing the residual error. The parameters of hepatossomatic index, mineral matter, and CAA, were higher in treatment with 1.6% of threonine in the diet. Based on the biomass parameters, relative weight gain, specific growth rate, and total weight gain, the appropriate level of threonine for catfish in that weight stage is 2.45% of threonine of the gross protein in the diet. |

Para tal foi realizado um experimento de dose-resposta com cinco níveis de inclusão de treonina (1,6; 2,2; 2,8; 3,4; 4,0% da proteína bruta (PB)) com quatro repetições. As dietas mistas eram isoprotéicas (37% PB) e isocalóricas (3400 kcal/kg de energia digestível estimada). Os juvenis de jundiá (peso inicial 4,47±0,39 g e comprimento 8,16±0,49cm) foram submetidos a 70 dias experimentais, alimentados três vezes ao dia até a saciedade aparente, e o consumo calculado diariamente. Os parâmetros de qualidade da água mantiveram-se dentro do ideal para a espécie. A cada vinte e um dias foi realizada biometria para avaliação dos parâmetros de peso, ganho de peso, taxa de crescimento específico e conversão alimentar aparente (CAA). A composição corporal, deposição de nutrientes, parâmetros metabólicos e enzimáticos foram avaliados ao início e ao final do período experimental. Os dados foram submetidos ao teste de normalidade, posteriormente a análise de variância, análise de regressão polinomial e regressão segmentada sendo escolhida a análise que melhor se ajusta aos dados através da comparação do erro residual. Os parâmetros de índice hepatossomático, matéria mineral e CAA, foram superiores no tratamento 1,6% de treonina na dieta. Baseando-se nos parâmetros de biomassa, ganho de peso relativo, taxa de crescimento específico e ganho de peso total o nível adequado de treonina para o jundiá nesta fase de peso é de 2,45% de treonina da proteína bruta da dieta.Universidade Federal de Santa MariaBRZootecniaUFSMPrograma de Pós-Graduação em ZootecniaRadünz Neto, Joaohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783033E5Lazzari, Rafaelhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4771019T6Fernandes, Joao Batista Kochenborgerhttp://lattes.cnpq.br/7653605390097019Flores, Daniel Prois2017-06-132017-06-132015-02-26info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfFLORES, Daniel Prois.
