Resumo: ABSTRACT. de Azevedo R.V., Ramos A.P. de S, Carvalho J.S.O. & Braga L.G.T. [Inclusion of cassava leaf meal for juvenile Nile tilapia.] Inclusão do farelo da folha da mandioca para juvenis de tilápia do Nilo. Revista Brasileira de Medicina Veterinária 38(3):305-310, 2016. Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural, Av. Conde D’Eu 344, Centro, Ibiraçu, ES 29670-000, Brasil. E-mail: azevedorv84@gmail.com This work examined the performance, intestinal morphology and viability of including cassava leaf bran (CLB) in diets for Nile tilapia, Oreochromis niloticus. It was distributed 160 fish (41.30±1.46 g) into 20 hapas (0.60 x 0.50 x 0.30 m), installed within ten polyethylene tanks (310 L) in a completely randomized design with four treatments and five replications. The treatments consisted of a diet free of CLB and three diets with inclusion (10, 20 and 30%) of the CLB. Performance were evaluated as feed intake (FI), weight gain (WG), feed conversion rate (FCR) and survival (SUR). In morphometric analysis, was measured the height (HEI) and width of intestinal villi. For the economic analysis of diet were analyzed the cost of feed per kg weight gain (CFK) and economic efficiency index (EEI). Data were subjected to analysis of variance at 5% probability and polynomial regression. There were significant negative effects (P<0.05) of the inclusion of CLB on FI, WG and FCR, with increasing inclusion of CLB, does not influence (P>0.05) SUR. It was observed a significant effect (P<0.05) of level of inclusion of the CLB in the diet of tilapia on HEI, observing decreased linearly with increasing inclusion of CLB. It was observed that the inclusion of CLB increased significantly with increasing linear behavior, CFK, and hence worsened the EEI. It is concluded that the inclusion of the CLB is not feasible on the performance and economically, besides affecting the absorptive capacity of Nile tilapia, degraded performance.

Foram distribuídos 160 peixes (41,30±1,46g) em 20 hapas (0,60 x 0,50 x 0,30 m), instaladas no interior de dez caixas de polietileno (310 L), em delineamento inteiramente casualizado com quatro tratamentos e cinco repetições. Os tratamentos consistiram de uma ração isenta do FFM e três rações com inclusão (10; 20 e 30%) do FFM. Como desempenho zootécnico foram avaliados: consumo de ração (CR), ganho de peso (GP), conversão alimentar aparente (CAA) e sobrevivência (SOB). Na análise morfométrica foram medidas altura (AVI) e largura das vilosidades intestinais (LVI). Para a análise econômica das rações, foram analisados o custo de ração por kg de ganho em peso (CRK) e o índice de eficiência econômica (IEE). Os dados obtidos foram submetidos à aná- lise de variância em nível de 5% de probabilidade e regressão polinomial. Houve influência negativa (P<0,05) da inclusão do FFM sobre as variáveis CR, GP e CAA e o aumento da inclusão do FFM não influenciou (P>0,05) a SOB. Houve efeito (P<0,05) do nível de inclusão do FFM na ração sobre a AVI, observando-se comportamento linear decrescente com o aumento da inclusão do FFM. Observou-se que a inclusão do FFM aumentou significativamente, com comportamento linear crescente, o CRK e piorou o IEE. Conclui-se que a inclusão do FFM não é viável zootecnicamente e economicamente, além de afetar a capacidade absortiva da tilápia do Nilo, prejudicando o seu desempenho.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2016-09-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/107Brazilian Journal of Veterinary Medicine; Vol. 38 No. 3 (2016); 305-310Revista Brasileira de Medicina Veterinária; v. 38 n. 3 (2016); 305-3102527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVporhttps://rbmv.org/BJVM/article/view/107/55de Azevedo, Rafael VieiraRamos, Ana Paula de SouzaCarvalho, João Sérgio OliveiraBraga, Luís Gustavo Tavaresinfo:eu-repo/semantics/openAccess2020-12-23T17:25:48Zoai:ojs.rbmv.org:article/107Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2020-12-23T17:25:48Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false
