The use of alternative feeds aims to increase productivity and reduce the feed costs in aquaculture production. This objective of this study was to determine the nutritional value and optimal rate of fermented Leucaena Leaf Meal (LLMF) as well as the replacement of soybean meal (SBM) by LLMF in diets for Nile tilapia (Oreochromis niloticus). Five different iso-proteinous diets were prepared and fed to three replicates trial of group tilapia. Fish were fed 28% protein diets with substitution of LLMF 0%, 25%, 50%, 75%, and 100%. The parameters that have been observed consist of the survival rate (SR), specific growth rate (SGR) and feed efficiency (FE). The results showed that the best results of SR, SGR and FE were observed in LLMF 0% group; 100%, 1.27%, and 31.47%. However, these results were not significant differences (P>0.05) from LLMF 25% group; 93.33%, 1.19%, and 28.25%. The experimental study from the present work suggested that LLMF can be used to substitute until a 25% level which can provide the survival rate, specific growth rate and feed efficiency as well as feeds without LLMF.Pages: 160-163 | 518 Views 57 DownloadsDownload Full Article:
