Resumo: | The objective of this study was to evaluate the performance and the digestive enzyme activity in bullfrog tadpoles, fed with commercial ration during 60 days, at the density of one tadpole per liter in 30 L boxes. The parameters measured fortnightly were: survival, length, weight, ration consumption, and amylase, lipase and trypsin activities. There larger growth of the tadpoles occurred from the 15th to the 45th day – 20.61 mm. During the first 15 days, the tadpoles had the largest specific growth rate, 16.7% per day. From the 45th to the 60th day, the tadpoles had the largest weight gain, 3.98±0.73 g, the largest ration consumption, 14.40±1.14 g and the best feed conversion, 3.67:1.0±0.18. There was significant increase in enzyme activities after the 30th day. Relationships were observed between the specific enzyme activities and the different development phases of the tadpoles. |

Os parâmetros medidos quinzenalmente foram: sobrevivência, comprimento, peso final, consumo de ração, e a atividade de amilase, lipase e tripsina. O maior crescimento dos girinos foi do 15o ao 45o dia – 20,61 mm. Durante os primeiros 15 dias, os girinos apresentaram a maior taxa de crescimento específico, 16,73% por dia. Do 45o ao 60o dia, os girinos apresentaram o maior ganho de peso, 3,98±0,73 g, o maior consumo de ração, 14,40±1,14 g, e a melhor conversão alimentar, 3,67:1,0±0,18. Houve aumento significativo da atividade enzimática depois do 30o dia. Observaram-se relações entre as atividades específicas das enzimas e os distintos estágios de desenvolvimento dos girinos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPERJFilho, José Teixeira de SeixasOliveira, Maria Goreti AlmeidaMoura, Guilherme de SouzaGarcia, Silvana Lages RibeiroLanna, Eduardo Teixeira ArrudaSilva, Lilia Nogueira da2008-12-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/993Pesquisa Agropecuaria Brasileira; v.43, n.11, nov. 2008; 1617-1624Pesquisa Agropecuária Brasileira; v.43, n.11, nov. 2008; 1617-16241678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/993/5563https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/993/649info:eu-repo/semantics/openAccess2012-06-17T11:45:10Zoai:ojs.seer.sct.embrapa.br:article/993Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:45:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
