ABSTRACT The present study was performed to investigate the effect of feeding different levels of poultry by-product meal as untraditional ration constituents on fish performance, and apparent digestion coefficients. A total number of 90 apparent healthy Nile tilapia fingerlings were randomly distributed into 5 groups, each of 18. The first group was considered as a control (T1) and was fed ad- ...

Hi Mr. Elsayed, thank you for the posting about the evaluation of Poultry-by Product as Feedstuff in the Diets of Nile Tilapia. However, in the abstract where you say ''There were no significant (P<0.05) differences'', the ''<'' sign is wrongly used. It would have been P>0.05. While the subject is necessary, the absence of replication and the small n used makes one question the ability of this study to detect a truly existing difference amongst treatments.
Thank you.

Thank you for your interest but our work is on the nutritive value and we don´t measure the water quality as water changed every day and also we use filters to avoid stress of water pollution by anything

Dear Dr. Elsayed Mickdam, Good work, Did the poultry by product meal include feathers? It would have been very much interesting if you had done chemical analysis of flesh as the results of your work hints involvement of some fat metabolisms as well.

Dear Christopher Hettiarachchi, thank you for your question, poultry byproduct meal contain feather and concerning flesh analysis the research includes protein deposition and energy deposition of fish in all treatments but we did not include it in the paper.

In our poultry operation, we produce feather meal and offal meal separately and if I am to formulate a feed for Tilapia, what would be the maximum inclusion rate of feather meal with offal meal in the diet?

Thank you for your interest, but in my research I use combination of both feather and offals with offals domenant. I dont know what is the percentage of both as the factory in my town do not produce them separatedly
