Resumo: | Knowledge of the growth of animals is important so that zootechnical activity can be more accurate and sustainable. The objective of this study was to describe the live weight, development of liver tissue and fat body, leg growth, and cumulative food intake of bullfrogs during the fattening phase using nonlinear models. A total of 2,375 bullfrog froglets with an initial weight of 7.03 ± 0.16 g were housed in five fattening pens (12 m2). Ten samplings were performed at intervals of 14 days to obtain the variables studied. These data were used to estimate the parameters of Gompertz and logistic models as a function of time. The estimated values of weight (Wm) and food intake (FIm) at maturity and time when the growth rate is maximum (t*) were closer to expected values when the logistic model was used. The Wm values for live weight and liver, adipose and leg weights and the FIm value for food intake were 343.7, 15.7, 19.6, 96.03 and 369.3 g, respectively, with t* at 109, 98, 105, 109 and 107 days. Therefore, the logistic model was the best model to estimate the growth and food intake of bullfrogs during the fattening phase. |

O objetivo do estudo foi descrever o crescimento em peso vivo, dos tecidos hepático e adiposo, da coxa e o consumo alimentar acumulado da rã-touro na engorda, através de ajuste de modelos não lineares. Foram utilizados 2.375 imagos de rã-touro com peso inicial de 7,03±0,16g, os quais foram alojados em cinco baias de engorda com 12 m². Foram realizadas 10 amostragens, a cada 14 dias, para obtenção das variáveis estudadas. Os dados amostrados foram utilizados para estimar os parâmetros dos modelos de Gompertz e Logístico em função do tempo. Os valores estimados de peso (Pm) e consumo à maturidade (Cm) e tempo em que a taxa de crescimento é máxima (t*) dos parâmetros avaliados foram mais próximos do esperado no modelo Logístico. Os valores de Pm para peso vivo, tecido hepático e adiposo, coxas e Cm para consumo alimentar foram 343,7 g; 15,7g; 19.6g; 96,03 e 369,3g, respectivamente, com t* aos 109, 98, 105, 109 e 107 dias, respectivamente. Portanto, o modelo Logístico foi a melhor ferramenta para estimar o crescimento e o consumo alimentar da rã-touro na fase de engorda.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista Júlio de Mesquita Filho Centro de AquiculturaUniversidade Estadual Paulista Júlio de Mesquita Filho Departamento de ZootecniaUniversidade Estadual Paulista Júlio de Mesquita Filho Centro de AquiculturaUniversidade Estadual Paulista Júlio de Mesquita Filho Departamento de ZootecniaEditora da Universidade Federal de LavrasUniversidade Estadual Paulista (Unesp)Pereira, Marcelo Maia [UNESP]Mansano, Cleber Fernando Menegasso [UNESP]Silva, Edney Pereira Da [UNESP]Stéfani, Marta Verardino De [UNESP]2015-02-02T12:39:39Z2015-02-02T12:39:39Z2014-12-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article598-606application/pdfhttp://dx.doi.org/10.1590/S1413-70542014000600009Ciência e Agrotecnologia.
