| The aim of the present study was to evaluate the feasibility of using biosilage produced from chicken waste and to replace this product in the diet of rainbow trout instead of fish meal. Because biosilage has higher properties and lower prices than fish meal. For this purpose, after producing biosilage based on fermentation of autogenous bacteria, is added to the diet formulation in the form of two treatments of 50% biosilage -50% fish meal and 100% biosilage and the growth performances and feed efficiency (WG, CF, SGR, FCR, PER) indices of these two treatments along with the control treatment (100% fish meal) on days 30 and 50 were evaluated and compared. The results showed that the indicators of WG, CF and SGR, in the treatment with 50% biosilage -50% fish meal are significantly higher than the other two treatments. It was also found that this treatment is more favorable than the other two treatments in terms of FCR and PER. According to the results, biosilage produced from chicken waste is a good alternative to fish meal. In addition, 50% biosilage-50 fish meal treatment is more desirable in terms of growth and feed index than 100% fish meal and 100% biosilage treatment. |
