Abstract  

Haematological, Histopathological, and Internal organs response of African catfish (Clariasgariepinus) fingerlings, were used as selection criteria for three auto-detoxified mixtures of Jatropha kernel cake with bovine blood (ADMJKC/bb) coded, Y3, Z2, and Z4. Each of the three test ingredients was evaluated at a 30 % and a 50% replacement level with fishmeal. Thus with a control, the ingredients were compared in seven iso-nitrogenous and iso-caloric diets (control, Y330, Y350, Z230, Z250, Z430, and Z450). The control significantly (P<0.05) had higher haemoglobin level, packed cell volume (PCV) and lower white blood cell count (WBC) than the ADMJKC/bb test ingredients. Similarly, increasing the ADMJKC/bb from 30% to 50% of reduced the PCV and increased WBC. However, the PCV and WBC in Z430 were significantly (P<0.05) different from their Z230 and Y330.counterparts. Histopathology and internal organ response followed similar trends as haematology. This lead to the conclusion that, the Y3 and Z2 ADMJKC/bb ingredients were better detoxified than the Z4 ingredient. However, Y3 and Z2 should not replace more than 30% of fishmeal diets for C. gariepinus fingerings. Therefore, there is a need to continue development of the Y3 and Z2 ingredients for C. gariepinus and other farm animals.
