The water quality parameters were within the recommended ranged for C. gariepinus.</em><em> Crude protein, crude lipids, dry – matter and </em><em>carbohydrate digestibility values of the experimental diets were; 86.97±3.5 – 89.25±2.8 %,</em><em> </em><em>83.50±2.6 – 85.35±2.3 %, 66.71±2.4 – 69.35±2.7% and 51.38±1.4 – 52.58±1.5% respectively. There was no significant difference (p>0.05) in the ADC values of </em><em>crude protein, crude lipids, dry – matter and </em><em>carbohydrate. The incorporation of co – mixed of betaine/β – glucan additive at different levels into the diet of</em><strong><em> </em></strong><em>C. gariepinus</em><strong><em> </em></strong><em>fingerlings had </em><em>no significant (p>0.05) </em><em>effects on</em><em> the ADC values of crude protein, crude lipid, dry – matter and carbohydrate. </em><em>C. gariepinus</em><strong><em> </em></strong><em>fingerlings should be fed with </em><em>co – mixed of betaine/β – glucan as feed additive. However, other feed additives could be employed which may further promote the digestibility of the feed.</em></p>}, journal={Nigerian Journal of Animal Production}, author={Ali, M.
