Abstract

African catfish Clariasgariepinus fingerlings were used as a model to evaluate diets containing three auto-detoxified mixtures of Jatropha kernel cake with bovine blood ADMJKC bb ingredients The test ingredients and a control were used to produce seven isonitrogenous and isocalorificdiets in which they either replaced 30 or 50 level of fishmeal The Jatropha kernel cake mixed with bovine blood at a ratio of 2 1 heated spread dried remoistened and substituting 30 of fishmeal and the Jatropha kernel cake mixed with bovine blood at a ratio of 3 1 unheated spread dried without remoistening and substituting 30 of fishmeal were similar to the control in feed conversion ratio and feed cost per gram of gain
