Dried Poultry Manure Meal as a Substitute for Soybean Meal in the Diets of African Catfish (Clarias gariepinus) (Burchell 1822) Advanced Fry
Öz
The effect of replacement of Soybean meal with dried poultry manure meal in the diets of Clarias gariepinus advanced fry was investigated. Six iso-nitrogenous diets containing 40% crude protein in which the soybean meal protein was replaced by dried poultry manure meal protein at 0% (diet PM1), 20% (diet PM2), 40% (diet PM3), 60% (diet PM4), 80% (diet PM5) and 100% (diet PM6) levels were formulated and fed to C. gariepinus advanced fry of average weight of 0.35g for 8 weeks in adapted aquaria. At the end of the trial, weight gain of 1.35 g was the highest in fish fed diets PM1 and PM4. Feed conversion ratio (FCR) of 1.89 was the lowest in fish fed diet PM3 but not significantly different (P>0.05) from 1.90 of fish fed diets PM1 and PM4. Net protein utilization (NPU) was the highest in fish fed diet PM1 with a value of 39.35% and the lowest with a significant difference (P<0.05) in fish fed diet PM6 with a value of 34.26%. Percentage survival value of 87% in fish fed diet PMI was significantly the higher (P<0.05) than 80% of fish fed diets PM2,3 and 4 and the lowest in fish fed diets PM5 and PM6 with an equal value of 60% respectively. In view of the above, it is evident that dried poultry manure meal can replace up to 60% of soybean meal in the diets of C. gariepinus advanced fry.
