    abstract = {A 30% crude protein control diet was formulated for the Nile Tilapia, Oreochromis niloticus with fishmeal as the main protein source.  The fishmeal content was replaced with soaked and cooked soybean at 25, 50, 75 and 90% equi-protein levels.  Diets were designated as D1, D2, D3 and D4 respectively.  Oreochromis niloticus fingerlings (mean weight, 10g) were randomly distributed at 20 fish per tank in duplicates.  After seven days of  acclimation, the fish were fed on the experimental diets for 21 days.  Faecal collection was carried out using five  different methods: siphoning directly from  the  aquaria,  stripping  by  applying pressure on the intestinal  section  and  collection  of  samples  from  three  sections  of the intestine: upper region, middle region and lower region. Acid  insoluble ash  was used as internal marker to assess digestibility of crude protein, lipid,  ash  and  carbohydrate  (NFE).   In the  siphoned, stripped and middle intestine collection methods fish fed  diet  2  had  the  highest  digestibility  coefficients  in  crude  protein,  lipid,  ash and NFE, while in  the  upper  and lower intestine the control diet had the highest digestibility coefficients in crude protein, lipid and NFE.  In samples collected from the lower intestine diet 4 had the least digestibility of all nutrients.  While n the upper intestine fish on diet 3 had the least nutrient digestibility except in NFE.  Diets 3 equally had the least digestibility in the siphoned diets except in NFE. In crude protein fish fed diet 2 had the highest digestibility of nutrients while those on diet 3 had the least.  Highest numerical quantification of digestibility occured in the siphoned method while the least was in the stripped. This study shows that soybean inclusion levels and sampling methods have significant effects on the coefficients of digestibility.}
