Resumo: | The objective of this work was to evaluate feed addition of exogenous digestive enzymes amylase, lipase, and protease on the tambaqui performance in three independent experiments. In each experiment, the effect of different percentages of enzyme inclusion in the feed was evaluated: 0.0, 0.05, 0.1 and 0.2%, each with four repetitions, in a 28 days duration. Initial biometrics for the initial weight were performed for sample homogenization, and for the final weight, to verify treatments effect on fish performance. Each experimental unit was stocked with ten fish, and fed on up to apparent satiety twice a day (8 and 14h), on a commercial extruded feed containing 28% crude protein, grounded, added enzymes levels and then pelleted. At the end of the experiment weight gain, apparent feed conversion, and specific growth rate presented significant differences between treatments. Exogenous enzymes amylase at 0.05% and lipase at 0.2% in diets influenced juvenile tambaqui zootechnical performance. The addition of the exogenous protease did not present the same influence. |

Em cada experimento foi avaliado o efeito da inclusão de uma enzima na ração em diferentes porcentagens: 0,0, 0,05, 0,1 e 0,2%, cada uma com quatro repetições, com 28 dias de duração. Foram realizadas biometrias do peso inicial, para homogeneização da amostra, e do peso final a fim de verificar o efeito dos tratamentos sobre o desempenho dos peixes. Em cada unidade experimental foram estocados dez peixes, alimentados duas vezes ao dia (8 e 14h) até a saciedade aparente, com ração comercial extrusada com 28% de proteína bruta, triturada, adicionada de enzima e depois peletizada. Ao final do experimento, o ganho de peso, a conversão alimentar aparente e o crescimento específico dos peixes, apresentaram diferenças significativas entre os tratamentos. As enzimas exógenas amilase a 0,05% e lipase a 0,2% na ração influenciaram o desempenho zootécnico de juvenis de tambaqui. A adição de protease exógena não apresenta a mesma influência.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNunes, Érica da Silva SantiagoCavero, Bruno Adan SagratzkiPereira-Filho, ManoelRoubach, Rodrigo2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7117Pesquisa Agropecuaria Brasileira; v.41, n.1, jan. 2006; 139-143Pesquisa Agropecuária Brasileira; v.41, n.1, jan. 2006; 139-1431678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7117/4162info:eu-repo/semantics/openAccess2014-09-25T17:01:40Zoai:ojs.seer.sct.embrapa.br:article/7117Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-25T17:01:40Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
